"Bad things happens to bots when I leave their side."
―Miko to Wheeljack in Hurt.

Miko Nakadai (仲代ミコ, Nakadai Miko) is a 15-year old girl from Japan with a strong love of American pop culture. Shriek metal and wild punk outfits are her thing and she's always searching for thrills, causing trouble for her friends Jack Darby and Raf Esquivel. Miko started to hang out with her best friend Bulkhead too, helping him get over his fear of hurting his tiny partner and encouraging him to get in trouble with her. However, when the chips are down, Miko looks out for her friends and will do whatever it takes to ensure their safety.

Miko is a supportive friend and a member of Team Prime.


When living in Tokyo, Miko had two loving parents and two purebreed cats, named Chi Chi and Ding Dong. Miko went to the best school and took piano lessons from the age of three, but she found it all so boring that she jumped at the chance to transfer to Jasper, Nevada. Once there, she learned English and became very fluent in the language with only a trace of Japanese accent and quickly realized that the brochure had lied about Jasper being "the entertainment capital of the world", and soon piano lessons seemed pretty good in comparison.

Miko was sitting outside her high school sketching Arcee, who was parked in motorcycle mode in a very colorful and creative way. She received a phone call from her host parents, but decided to ignore it. When Jack rode off on Arcee, she decided to follow the motorcycle because it was the coolest ever. She caught up to Jack in an alley in time to overhear Arcee, who had transformed to robot mode, asking Jack to go back with her to Autobot headquarters for his own safety. When Jack hesitated, Miko encouraged him to go. Since Miko now knows about the Autobots, Arcee took both of the humans back to headquarters. When Ratchet was surprised to see three humans, Arcee wryly explained that the youngsters had multiplied. Miko introduced herself to Bulkhead and promptly asked a barrage of questions, leaving the Autobot at a loss for words. Optimus Prime arrived and explained about "autonomous robotic organisms" and the Transformers civil war.

Ratchet picked up Cliffjumper's signal, but believed it was a computer system error, since Cliffjumper had previously gone offline. Prime went to investigate anyway. Miko offered to help, but Prime told the humans to remain with Ratchet, to both Miko and Ratchet's dismay. When the humans had to return home, Prime assigned Bulkhead to watch over Miko.

Bulkhead didn't need much encouragement to take Miko on an off road jaunt on their way back to base. When they eventually reached their destination, they were deserted by pretty much all of the other Autobots, leaving them at the base with Jack and Raf. Miko decided to make the best of things by organizing those remaining into a band, and she kicked off with a solo on her electric guitar. Fortunately for the others, Agent Fowler picked this moment to make a return visit to complain about the energon mine explosion. The kids hid behind Bulkhead, but Miko's guitar gave them away. It was only Bulkhead's intervention that stopped Fowler from taking them into custody then and there. After the agent left, the base equipment picked up a distress call from his helicopter, suggesting he'd been captured by the Decepticons. When Bulkhead used the ground bridge to mount a rescue mission, Miko tagged along, unseen until it was too late. Bulkhead noticed her when she spoke up, but so did one of the Decepticon sentries, leading Miko to witness Bulkhead disemboweling the con. (He'd warned her not to look, but she thought it was awesome anyway.) They were joined a short time later by Jack and Raf, who accidentally attracted the attention of more sentries on the Decepticon ship.

Miko rode in Bulkhead's back seat as he swooped in and picked up the two other kids... and then stayed in there as he drove under the ship, transformed, scaled a nearby cliff and fought some Decepticons. After spewing on his floor mats, she knocked and he let her out. She discovered that the middle of a fight between Bulkhead and some Decepticons was no place for a young human to be. Once they moved into the ship, he was forced to slide her along the floor to keep her safe. They quickly ran into Arcee and Bumblebee with the two boys and after some more fighting, the Autobots cleared a room for the kids to hide in. Miko and Jack began arguing, which upset Raf, and the pair had to console him. They noticed a computer screen displaying important info, but before they could make a copy, a Decepticon appeared. Jack yelled to Miko to get a photo with her cell phone, but only after she snapped a picture of the con did he clarify that he meant the readout. They were subsequently rescued once again by the Autobots and Miko observed on the way back to base that they succeeded in rescuing Fowler. Miko was exuberant over their experiences as she handed over the picture, but Jack was furious that they'd all almost gotten killed. After he opted to return to his normal life, Miko paid him a visit and unsuccessfully attempted to convince him that the exciting life they had with the Autobots was much better.

When they discovered that the Decepticons were using the Giant Sized Array radio telescope in Texas for their space bridge, Miko accompanied Jack and Raf there to do some on-site hacking. It wasn't long before Soundwave spotted them and sent a tentacle to attack them, knocking Miko and Jack aside. Miko tried to strike at the appendage with an axe, only to miss and have the tentacle snatch up the weapon. They chased it into the next room, where Soundwave had severed the computer system's hard line. Miko took a picture of the Decepticon as he flew away and he responded by snapping a picture of the three of them. Defeated, the kids returned to base, where they monitored the Autobots' progress in destroying the space bridge. After the Autobots returned, Miko wondered if Optimus would now ask them to go home and forget everything that happened. (The answer, apparently, was no.)

Tasked with creating a science project for school, Miko decided on a model of the solar system. Bulkhead helped her by holding it up so she could paint it, but Ratchet somehow took over all of the kids' projects, leading her to observe he was a bit of a control freak. He produced a scale model of Cybertron for her which was not well received at school and Miko presumably did not achieve a high grade on it.

The kids arrived at base one Saturday just as Optimus and Arcee were heading out on a mission. She challenged Jack to a video game, but soon found herself on the losing end, at least until a random power fluctuation stopped the game. The reason for the malfunctions was revealed when Raf returned to the control room with a small metal critter the Autobots called a Scraplet. The day proceeded to be a series of surprises for Miko. First, Raf killed the Scraplet he'd found with a crowbar after it attacked Bumblebee and second, when she was Scraplet-hunting with Bulkhead, she discovered that the large Autobot screamed like a little girl. After they returned to the control room, she helped Jack and Raf fight the Scraplets off their Autobot friends. A plan was formulated to rid the base of Scraplets using the ground bridge, which meant the three kids had to repair an energon fuel line rupture. After the successful expulsion of the invaders, they helped repair Bulkhead and Bumblebee, but Miko was scared off by an itsy bitsy spider.

Miko was excited by the news that a new Autobot, Wheeljack, was coming to Earth, but figured if he was going to stick around, he'd have to find his own human. She hit it off with Wheeljack right away, and when the Autobots decided to celebrate, brought out her electric guitar. The kids listened to Bulkhead's tales of the old days on Cybertron, and then Wheeljack asked Miko to show him around the base. She answered all of his questions about where the base was and the contents of the armory, but after they returned to the control room, Bulkhead unmasked Wheeljack as a Decepticon impostor. The impostor took Miko hostage, threatening to squish her. After the ground bridge was activated, the real Wheeljack came through and hit the impostor, knocking Miko out of his grip and into Bulkhead's waiting hand. Once the impostor was disposed of, they again partied and Miko played her guitar some more. The three kids turned out to see Wheeljack off as he left for space, and Miko snapped off a picture of him and Bulkhead on her cell phone.

When the Autobots helped Fowler move a hi-tech device, the kids observed their progress from base with Ratchet. The Dynamic Nuclear Generation System was in danger of being captured by MECH, and Miko had the bright idea that Ratchet could ground bridge them onto the speeding train that was transporting the object. With some help from Raf, Ratchet got Jack and Miko on the train, and Miko grabbed a fire ax to try and defend the device with. The MECH goons ended up retreating after seeing Optimus. Silas blew up the track ahead of the train, and for a few moments, Jack and Miko thought they were doomed—Miko even asked Raf to make sure Bulkhead got her beloved electric guitar—but Optimus managed to stop the train in time.

Miko skipped out of detention one day when Bulkhead arrived outside the school, earning herself a lecture. Bulkhead took her on a mission to Greece, with the theory that she could use the time to work on her history report, but instead they found an ancient fresco showing an Energon Harvester. Breakdown arrived and used Bulkhead to break the fresco, but luckily, Miko had already snapped a picture of it with her phone. When Raf located the actual Harvester in a museum, Miko volunteered the services of the three kids to go in and retrieve it. After some deft work disabling a security camera with her phone, she, Jack and Raf were able to swipe the Harvester, but while making their escape, Miko was caught by a security guard. While they waited for the police, Miko bored him with every bit of knowledge she could remember about Greek history. Eventually, Fowler arrived to bail her out, and she happily told Bulkhead that she was going to write her history project on how the Autobots interacted with ancient races.

At school, Miko and Raf heard all about Jack's race with Vince, the local bully, and they congratulated him when he reached the Autobot base. He swore them both to secrecy. After Vince challenged Jack to another race but Arcee refused to take part, Miko helped Jack convince Raf to let him take Bumblebee instead. Miko and Raf subsequently failed to cover for Jack and Bumblebee's absence, first with Arcee, and then with Optimus.

After Optimus was struck down with a Cybonic plague and Arcee and Bumblebee infiltrated the Decepticon ship, the three kids watched Ratchet monitor the pair's progress as Arcee patched Bumblebee into the comatose Megatron's mind to find the cure. Miko later acted as referee for a basketball game between Bulkhead and Bumblebee.

When the Autobots detected a Dark Energon signal, Miko cheered Bulkhead on, but her seeming not to want to go alone made Jack and Raf suspicious. Sure enough, she made a break for the GroundBridge, and though Jack tried to stop her, she and the two boys ended up on the battlefield. The Autobots finally noticed them when she realized that she'd lost her cellphone and yelled at Jack. The kids were promptly sent back through the bridge, but interference from a Decepticon GroundBridge caused a disruption which deposited the trio in the Shadowzone . Unable to be seen or heard by the Autobots, they were pursued by Skyquake who had been resurrected as a zombie by Starscream. After Raf dropped his glasses, Miko risked her life to retrieve them. The kids managed to send a text to Miko's phone back at base to alert the Autobots, and attempted to use Starscream's severed arm against the rampaging Skyquake but only succeeded in dislodging his arm, which promptly began chasing them as well. The three kids returned to reality through a special GroundBridge portal engineered by Ratchet and, much to Jack's surprise, Miko took responsibility for the entire mess. Optimus said she'd went through was enough.

After Bulkhead was knocked out during a fight with Breakdown, Miko eventually managed to reach him on the comms, and he requested a GroundBridge back to base. She was disappointed to learn that Bulkhead hadn't manage to trash his foe, who had instead been snatched by MECH. She was even more dismayed when Bulkhead refused to go on the mission to rescue his arch-enemy, insisting that he should be the one to do it so that he could have a rematch. Even Dinolizard vs. Five-Headed Ape wasn't enough to distract her, and she eventually talked Bulkhead into going to Russia on his own to try to rescue Breakdown.

Miko was at the Autobot base when Jack and Arcee brought Jack's mom in to introduce her to everyone. Unfortunately, Jack's killjoy mom started making a habit of hanging out at the base, so things weren't as fun as they had been before. When Miko wanted to go on a mission with Bulkhead, he felt obliged to tell her to stay put because it wouldn't be safe. Miko managed to sneak along anyway, and persuaded Arcee not to make her go back to base. Though Arcee made them turn the rock music off, Miko got to hang out with Bulkhead, at least until they found Breakdown and Airachnid. From the cover of rocks, Miko attempted to snap a picture of the fight, only to have her phone snatched from her hand. The Decepticons' polarity gauntlet stuck Arcee and Bulkhead together, and as the further pursuit would be dangerous, Arcee insisted on Miko returning to base, causing the girl to complain loudly that Arcee was as bad as Jack's mom. After the mission, Miko took a picture of Bulkhead's new battle scars.

Miko was looking forward to a Slash Monkey concert when she was roped into going to an old energon mine with Jack, Bulkhead and Arcee. After complaining a lot, she slipped inside to test the mine's acoustics, only for a cave-in to occur, trapping her and Bulkhead. While Bulkhead supported the roof so it didn't crush them both, Miko attempted to clear some of the rocks but eventually became exhausted. They were eventually found, but not by Arcee as they had hoped, but by Starscream. After the Decepticon chased her around a bit, Jack arrived on a mining drill. Tearfully, she left Bulkhead behind and the two kids made a break for the surface. After Arcee rescued Bulkhead, they joined the two kids and escaped from the mine.

Bulkhead and Miko sneaked into a monster truck rally and Miko recorded parts of it on her phone. A week later, they were reviewing the footage when Bulkhead was called into the field to help retrieve Cybertronian data cylinder. Unimpressed at being told to clean the place by Ratchet, Miko followed Bulkhead to a battle field where the Autobots and Decepticons were battling in an attempt to claim the cylinder. Miko ran into safety and managed to call Ratchet for a groundbridge, but she couldn't give him enough precise coordinates to reach to the Cylinder and was forced to hang up when she dodged a blaster from a Vehicon. Left with no other choice, she unsuccessfully tries with desperation to push the Cylinder into the groundbridge. She tries pushing harder with all of her strength, but she isn't strong enough to move such a large object. She then tries kicking the Cylinder, but only succeeded in making it eject its contents into Bulkhead's cranium. Though Bulkhead seemed fine at first, he started painting formula at a mad rate, and when Miko realized he was beginning to forget things, she had it confirmed by Ratchet that the data from the cylinder was slowly destroying Bulkhead's mind. In an attempt to try and jog Bulkhead's memory, she took him to the monster truck track, only to be found by Knock Out and Breakdown. Miko attempted to conceal Bulkhead and contact the other Autobots, but when the searching Decepticons found Bulkhead, she tried to stop them removing his head. She again triggered the cylinder energy, which left Bulkhead and fired off into space. She believed that the energy had taken Bulkhead's mind with it, and was near inconsolable until something Ratchet said prompted her to get out her guitar, and the sound from it caused the comatose Bulkhead to wake up.

Miko lent her voice to "Mars Cat", which Raf used to cover up evidence of the Autobots which had found its way on to conspiracy websites. After Raf was gravely injured in an attack, Miko watched Ratchet and Mrs. Darby work to save his life and gave Raf a hug when they succeeded.

When June attempted to take the children with her when she left the base, Miko refused to go, asserting that neither June nor Bulkhead were her mother. As the Autobots discussed the ramifications of Unicron being at the center of the Earth, Miko wondered if Unicron would stretch and make the Earth explode. Optimus wasn't sure.

The humans listened as the Autobots battled giant stone Unicrons, and as Megatron arrived to offer to help the Autobots defeat Unicron. Miko was alarmed at the thought that Unicron would remain in the Earth's core after his defeat, but Raf and Ratchet explained that Unicron was the Earth's core and removing him would not be possible. To Miko's annoyance, the humans were instructed to hide when Megatron arrived. After Raf ran out to confront the Decepticon leader, Miko got her chance to holler that she would make sure Megatron would regret double-crossing any of her friends and had to be dragged away by Fowler. The humans all watched the Autobots and Megatron step through the GroundBridge into Earth's core.

Ratchet told the kids about Optimus back when he was Orion Pax, and how he got the Matrix. Miko and Raf were both concerned when they lost the Autobots' signals. The kids all took shelter underneath Ratchet when the ground started shaking, but were overjoyed when it turned out Prime's team had succeeded. They welcomed the Autobots back, but were shocked by the loss of Optimus, who had become amnesiac.

When it was determined they would need to reach Cybertron to deal with the problem, Miko suggested using the GroundBridge, adding that Ratchet could turbo-charge it when Raf pointed out that it could barely reach orbit. She was present at base when the Autobots failed to stop the Decepticons from stealing a power source for a new space bridge and thought Jack's plan to commandeer the Decepticon bridge was a good idea. Miko turned out to see Jack off as he left for Cybertron, though she seemed more concerned with how Jack was going to use the toilet in the spacesuit Fowler had supplied. Miko and the others monitored Jack's mission on Cybertron until he returned with the Autobots and a restored Optimus Prime.

After Bumblebee's T-cog was taken, Miko suggested that Ratchet make another one, only to be told it wasn't possible. She and Raf tried to cheer Bumblebee up, but all of their entertainment seemed to revolve around cars, which just made things worse. She and the other kids hung around for an attempted transplant and subsequently covered for Bumblebee when he went to get his cog back.

The kids were racing toy cars when Fowler reported being attacked by Optimus. They stuck around as Optimus returned and it turned out he was being impersonated by a MECH creation which Miko dubbed "Nemesis Prime". Later she asked Bulkhead, Bumblebee, and Arcee on how it felt to be attacked by an imposter that looked like Optimus, to which Arcee responded by stating its a sight she won't forget. 

After the Nemesis became sentient, the kids GroundBridged aboard with Fowler to try and download the Iacon database. When they learned the ship was heading for New York City and Fowler was rendered unconscious, they headed for the power core. Miko and Raf ended up playing hide and seek with one of the ship's manipulator arms while Jack worked on reversing the energon flow. After succeeding, they high-tailed it back to the GroundBridge.

Jack and Miko volunteered to go to Manhattan with Arcee and Bumblebee in search of one of the relics. The two kids encountered Vogel, a sweeper train driver whom they took into their confidence. With his help, they used the sweeper train to hit Knock Out, but this resulted in the train barreling out of control. With a little assistance from Arcee, they stopped the train by running it into Knock Out, and subsequently got Fowler to draft Vogel to ensure his silence.

Going after HardshellEdit

After their victory, Miko rode in Bumblebee's passenger seat as they were GroundBridged back to base. As they rode, she listened and motioned herself in conjunction with the music Bumblebee was playing until the latter turned it off, causing her to ask if he and Raf usually listen to other type of genres. As he answered, she concluded that while she had a pleasurable time with him, it was time for her to reunite with Bulkhead, whom she discovered at the base when Bumblebee nearly crashed into the latter's body. As Ratchet tried to stabilize Bulkhead, Miko blamed herself for Bulkhead's injuries, citing that if she had went with him, he wouldn't have been in his current state of being before agent Fowler stated that it was beyond her control.

As the group continued to register with his condition, Arcee exclaimed to Optimus that Wheeljack was on his way. Angered, Miko concluded the group had already given up on Bulkhead and lashed out at them for doing so before Arcee explained that since Bulkhead and Wheeljack shared a close relationship, she thought Wheeljack would want to be present. However, Miko did not believe her and continued to cite her own belief of Arcee's statement. As she walked away, Optimus Prime asked her where she going. Miko angrily shouted that she was going home and trying to catch up to agent Fowler, whom she hoped could give her transportation. In reality, she had actually snuck aboard Wheeljack's ship. After being spotted by the Autobot, she tried to convince him to allow her to accompany him to exact revenge on the Decepticon responsible for Bulkhead's near-death state. She earned her place at his side after making a bargain to reveal whom had tried to kill Bulkhead to him if she was brought along.

During their outing, she snuck into a cave Wheeljack himself could not enter, due to his height and size and alerted him of the Vehicons presently located near the energon mine. The two then contacted Megatron and allowed him to listen as the energon mine blew up. As the two rode together, Wheeljack suggested to Miko that she go to sleep for a while before Miko reassured him that she was fine and expressed her belief that Bulkhead was going to live before asking Wheeljack, who himself believed the same theory. After Wheeljack described Bulkhead's strength, Miko exclaimed that Bulkhead would not miss any of their upcoming objectives the two had made together. As they landed, Miko woke up and expressed disappointment in not being able to come along with Wheeljack, whom had present the ship to send her home in case he went offline. She become angry, citing that the two had a deal. Wheeljack stated that Bulkhead was going to wake up and would harm him if she were not present before leaving the ship, causing Miko to utter his name in frustration.

Despite Wheeljack's orders, Miko participated in his battle with Hardshell by shooting the Decepticon and killing him while he was fighting and nearly defeated Wheeljack. When Wheeljack reminded her that she was supposed to not intervene, Miko assured Wheeljack that bad things happened to Autobots when she left their side.

Treating Bulkhead/Captured and Traded/Leaving with BulkheadEdit

Really Bulk

As Bulkhead worked to recover, Miko attempted to loudly encourage him to work harder at it. She was upset by his slow progress, but Arcee told her the story an adventure with Cliffjumper, during which Arcee and Cliffjumper encountered Shockwave and ended up on Earth. She continued to try to help Bulkhead, and when new Autobot Smokescreen arrived, tried to reassure him that he wasn't being replaced, despite herself being excited to see a new Autobot in Team Prime.

Bulkhead remained discouraged, despite Miko's ongoing support. She, Jack and Fowler were sent via GroundBridge to Raf's house when the Decepticons got control of a Project Damocles satellite and assisted him in destroying the satellite.

When Miko heard Cybertron might live again she made plans to live there with Bulkhead. She, Jack and Raf waited outside school one day for over an hour. When Jack called Ratchet he was told the Autobots were busy, Miko suggested Ratchet pick them up as he had nothing else to do but Ratchet told them to just go home. The kids were kidnapped by StarscreamSoundwave and Knock Out and brought to Cybertron to be traded for Omega Keys, which Miko stated it was not how she wanted her visit to Cybertron to turn out. Bulkhead handed over his key for Miko. Miko was amazed at the Omega Lock's power and wondered if it would restore Earth, before Optimus told her it would just turn Earth into another Cybertron. Optimus used the Star Saber to destroy the Omega Lock and as revenge the Decepticons stormed their base. Bulkhead and Miko bridged out to the Rockies.

Bulkhead took her to the Wrecker meeting point where they sat all night before Wheeljack showed up. When he did he briefed them on a plan to reunite the team to regroup the Autobots by blowing up an Energon mine to draw the attention of nearby allies. The trio were attacked by a Predacon and rescued by Ultra Magnus and Arcee. As part of Magnus' plan to destroy Darkmount, Miko used her cellphone to draw Vehicon forces to the East Coast. Like everyone, Miko was overjoyed when it turned out that Optimus Prime had survived. When the Autobots set up their new base, Wheeljack almost crushed Miko with his Wrecker Lobbing Ball.

A More Active RoleEdit

Miko attack!!!

Later, Miko is secretly brought along by Wheeljack on a mission to find Predacon remains in Scotland. Ultra Magnus agrees to bring her since the Decepticons are all dead. When the Predacon arrived Ultra Magnus had her go to his ship to contact base. When she arrived she found Starscream and two Vehicons. An explosion distracted the Decepticons and Miko ran for the lift to the ship. Starscream noticed and stopped her. Desperate, she ran for the Apex Armor. To everyone's surprise (Including Miko herself) it worked for her. After being used as a chew toy by Predaking, she used it to fight off Starscream and his elite Vehicons.

She was afterwards officially made a member of the Wreckers. Wheeljack praised her but was fed up with Bulkhead siding with Magnus and left. After the mission she called Jack to see if Wheeljack showed up at base and learned he had gone on a mission with Arcee. She kept the Apex Armor as her personal weapon. She witnessed Raf building Chip and the Autobots mobilizing to secure the Omega Lock.

Miko proved instrumental in securing the Omega Lock 2.0. As Soundwave was always using GroundBridges to defend himself, Jack had a plan of using the bridges against him but needed Miko as back up. Jack, Ground Bridged onto the Nemesis, where four Vehicons confronted him. Miko then jumped out, wearing the Apex Armor and killed the Vehicons. She charged on Soundwave who tried to force her into a Ground Bridge. Unknown to Soundwave, she was bait. Raf opened a Bridge behind Soundwave sucking him into the Shadowzone. Miko saved Jack from being sucked in with Soundwave as she now weighed enough to resist the pull of the malfunctioning GroundBridges. She was later tossed around like a butterball when Jack tried to fly the Nemesis leading her to ask "Dude, where'd ya learn to drive?". She later punched Knock Out when he tried to join the Autobots. When the Autobots left she cried at the fact that Bulkhead was leaving her. She was there to see Optimus giving his last glimpse at his human friends and Ratchet before going back to Cybertron with the rest of Team Prime. 

Physical AppearanceEdit

Miko has brown eyes, fair skin and medium-long black hair with pink highlights and is worn in a low ponytail and two twintails at the top of her head. She is slim, taller than Rafael, but a little short around Jack. She wears a two-toned purple t-shirt under a dark blue tank top with yellow stropes and a little green robot drawing, jean shorts, two-toned purple striped stockings, brown knee-high boots with purple ties and a soft two-toned purple bracelet as a match to her t-shirt.


If there is one word to describe Miko's personality its reckless. She is a thrill seeking adventurer who wants to be in on the action and has no regard for danger or her own safety and certainly no thought as to the potential consequences of her actions. Still she is, at heart, a good person who cares deeply about her friends and the Autobots. She is particularly close to Bulkhead her protector to the point of refusing to leave him at the mercy of Starscream. Her hot-headed and impetuous demeanor cause no end of headaches for her friends and Autobots. She also has a habit and hobby of taking pictures with her cell phone, which actually helped bots from time to time.

Though she may seem harmless, Miko is far more willing than most of her other companions to fight back. When Bulkhead was severely injured by Hardshell she teamed up with Wheeljack in order to take revenge. When Hardshell had Wheeljack beaten and had been ordered to flee in his ship, she instead chose to activate the Jackhammer's weapons systems and blew Hardshell to pieces. When his remains were brought to Megatron's attention, the Decepticon leader was surprised that even a human would be capable of such an act of violence.

Miko's act of killing Hardshell (by using the Jackhammer) was more to save Wheeljack. Miko didn't show remorse for killing Hardshell, but neither did she find satisfaction of her actions. Miko proved her bravery by confronting Soundwave himself singlehanded in Deadlock using the Apex Armor. She would do whatever it takes to prove herself and save or help her friends. She is also an arachnophobiac, that is, she is afraid of spiders.

She shows little regard for authority and rules which once led her to cut detention in Deus Ex Machina.


Miko is a skilled guitarist, owing to her love for rock music, and her favorite band is Slash Monkey. With the Autobots she became skilled in mechanical engineering, and she's somewhat of a photographer, using her cell phone to take pictures of the Autobots constantly. The cell phone apparently can synch with Autobot communications, seen when she used it to spy on a Decepticon energon mine and her phone's camera transmitted everything it saw and heard to Wheeljack's ship.

Miko is also bilingual, as she comes from Japan, but she speaks fluent English, likely due to her love of American pop culture.

By donning the Apex Armor, Miko was able to fight off two Vehicons and Starscream, with a haphazard fighting style as a mix of martial arts, sumo and wrestling. Despite the fact that she lacks muscle when she unsuccessfully attempted to; drag Acree's leg from Bulkhead's back, lift a giant rock to save herself and Bulkhead from danger or push a cylinder with all her might.


Caregivers/Temporary guardiansEdit

Miko's host parents (Not Miko's actual parents)Edit

Miko's real and loving parents live in Tokyo. She took part in a student exchange program where she left Tokyo and was placed under her host parents care. While her host parents are not seen physically, Miko does mention them and feels like she scares them. However, she seems to not mind being under their care for the time being.


Jack DarbyEdit

Prey Miko hugging Jack

Miko hugging Jack in Ultra Magnus' ship.

"Jack: Miko! *Miko hugs Jack* Ugh can't breathe."
― Jack and Miko reunited in Prey.
"Glad to be your bro, bro."
―Miko to Jack.

Miko goes to the same school as Jack and Raf. Miko met Jack when Jack encountered Arcee. Miko told Jack to go with Arcee and she tagged along on the ride, with Raf traveling in Bumblebee. They were brought into the Autobot's base and were introduced to Optimus Prime. Optimus explained to them about their existence and why the Autobots are fighting the Decepticons. After some time, Miko almost got Jack and Raf killed by the Decepticons when Miko went with Bulkhead to rescue Agent Fowler from the warship. Jack almost left the team, but Miko tried to convince him to stay. After the Autobots returned from destroying the Decepticon space bridge, Jack and Miko now work together as teammates and friends. In most episodes, Jack and Miko are seen to hang out, along with Raf too. In Tunnel Vision, Miko was jealous that Jack went to Cybertron but Jack reminded her that she was important to the team. In Darkest Hour, Miko and Jack shared a moment to look at each other as they were about to leave the base from being attacked by the Decepticons. Miko seemed sadden to leave Jack as she left inside of Bulkhead. In Prey, Miko reunited with Jack by joyfully hugging him. Miko thinks of Jack as her "bro" as she revealed in Plus One, which means she thinks of Jack like a brother figure. In Deadlock, Miko was in the Apex Armor as she protected Jack from being pulled into the shadowzone with Soundwave.

Jack protects, looks after and cares for Miko like a brother.


"Miko: Raf! *runs to Raf and hugs him*"
― Miko reunited with Raf in Prey.
Prey Miko hugs Raf

Miko hugging Raf

Like Jack, Miko met Raf when they encountered the Autobots and went inside their base. After the Autobots returned from destroying to the Decepticon space bridge, Raf and Miko work together as teammates and friends. In most episodes, Raf hangs out with Jack and Miko. They would often hang with their Autobot guardians or play video games in the Autobot base. When Raf was injured by Megatron, Ratchet saved Raf's life and Miko gave Raf a hug. In Prey, Miko was thrilled to see Raf as she runs and picks him up in a hug. This shows that Miko cares about Raf the most and gets concerned over his safety. After Ratchet was captured, Miko was surprised that Raf knew Cybertronian language.

Raf is like a little brother to Miko.

June DarbyEdit

June hugging Miko and Raf

June hugging Miko and Raf

Miko met Jack's mother in Crisscross. At first it seemed like Miko missed the old days before June started coming to the Autobot base. Miko also seems to ignore June's authority as it was revealed in One Shall Rise, Part 1 when June tried to get her and Jack to leave the base. However, in Prey, Miko was happy to see June as Jack pulled her and Raf into hugging June. Miko did not have no problem with it and hugged June back.

June is like a mother figure to Miko.

Optimus PrimeEdit

"Miko. Your quick thinking prevented the formula from falling into Decepticon hands."
― Optimus trying to lift Miko's spirits in T.M.I..
"Optimus saved our planet."
― Miko to Ratchet in Darkest Hour.
"Optimus 2.0 is rad!"
―Miko to Optimus in Rebellion.

Miko met Optimus Prime on her first encounter with the Autobots. Optimus introduced himself to the humans and told them of the Autobot's history. After destroying Megatron's plans to conquer Earth with an army of undead zombies, Miko hanged out with Optimus and the others in the base. Miko may no agree with Optimus at times, but she still respects him. Whenever Miko felt impaired, Optimus would comfort her. Optimus also saved Miko and Jack's life when they were trapped in a train that was heading to a blown part of its tracks, which was blown by Silas. Miko and Jack were thankful Optimus saved them. When the base was destroyed, the team was scattered. After sometime, Optimus returned in a new body and helped in destroying the Decepticon citadel. When the team retreated in a new base, Miko complimented Optimus on his new look, by saying "Optimus 2.0 is rad." In Deadlock, Optimus gave Miko a last glance before leaving to Cybertron.

Optimus and Miko remain good friends through out the show. Optimus cares about Miko and Miko loves having Optimus around. Miko would go "fan girl" at times when Optimus does something exciting or gets a new upgrade.


Watch the Sunset

Miko holding Arcee's hand as they watch the sunset outside of the base.

"Miko, you okay?"
―Arcee asking Miko in Hurt.

Miko sketched Arcee in her vehicle mode and then saw Jack talking to Arcee in a corner. Eventually, Miko and Arcee would hang out in the base with their fellow companions. Even though they rarely talk, Arcee regards Miko as a teammate and friend. Arcee would also comfort Miko whenever she felt impaired, even when Bulkhead was hurt. When Arcee told Miko of her past, Miko listened and asked questions about Cliffjumper. Arcee explained about Cliff and how they arrived on Earth. Arcee didn't expect to lose another partner and she tells Miko that nothing is louder than the silence. Miko held Arcee's hand, mostly her finger, as they happily watched the sunset together.

Miko and Arcee remain good friends through out the show. While she seems to be annoyed with Miko's little antics, Arcee would go along with it. Arcee cares and protects Miko like she does with Jack and Rafael. Arcee is also like an older sister figure to Miko.


Bumblebee and Miko are rarely paired together. In most episodes, Bumblebee hangs out with Miko and the other humans. In Tunnel Vision, Miko was very concerned when Bumblebee was about to crash in front of their sweeper train. Luckily, he survived and Miko was glad he did. In Out of the Past, Bumblebee was walking by Miko until she told him to move aside. Despite this, Bumblebee and Miko still care for one another. When Bumblebee got his voice back, Miko and the other humans were all surprised.

Miko talking about moving with Bulkhead on Cybertron.

"I wanna be just like you Bulk!"
―Miko to Bulkhead.

Miko immediately took a liking to Bulkhead when she first met the Autobots. She was ecstatic when Bulkhead was assigned to be her guardian. The two of them would go to monster truck shows and do dune bashing when they finished their chores. When Bulkhead was injured by Hardshell, Miko went with Wheeljack to avenge Bulk. In the Jackhammer, Miko was able to kill Hardshell just before the insecticon could kill Wheejack, avenging Bulkhead in the process. Back at the base, Miko said to Bulkhead that she will never leave him again. After a while of healing, Bulkhead slowly recovered and Miko trained him so hard because it was rough for her to deal with Bulkhead being injured. It was really hard for Miko to say goodbye to Bulkhead in Deadlock as she cried on his leg and Bulkhead gives her his finger to hold on.

Miko still cares for Bulkhead and would do anything to protect him. Miko is Bulkhead's best friend, next to Wheeljack. Bulkhead would do anything to protect Miko and cares for her as her guardian and closest friend.


"If anything happens to my favorite Wrecker, I'm coming after you."
―Wheeljack jokes with Miko.
"She may be small but she saved my tailpipe. Snuffed an Insecticon all on her own."
―Wheeljack to Ultra Magnus about Miko.
Chain of Command Wheeljack and Miko

Wheeljack and Miko

Miko met up with Wheeljack after Wheeljack defeated Makeshift who disguised himself as Wheeljack to invade the Autobot base. Wheeljack told Miko that if anything happened to Bulkhead, he would come after her. Miko said she will take care of Bulkhead and took a picture of Bulkhead and Wheeljack together. Later on, when Bulkhead was injured by Hardshell, Wheeljack had no choice but to take Miko with him to find Hardshell. Eventually, they found Hardshell and Wheeljack was fighting against him. Hardshell almost killed Wheeljack, but Miko was able to shoot Hardshell using the Jackhammer. Wheeljack and Miko are seen to hang around most of the time. Wheeljack even invited Miko to go on a predacon bone hunt with Bulkhead and Ultra Magnus. Ultra Magnus questioned Wheeljack on bringing Miko and Wheeljack replied that Miko saved his life from an insecticon. Ultra Magnus agreed and Miko was made an official member into the Wreckers when she obtained the Apex Armor from Starscream.

Wheeljack and Miko remain good friends. Wheeljack is like an adult figure to Miko and cares for her safety and well being.

Ultra MagnusEdit

"Perhaps you weren't wrong about the human after all."
―Ultra Magnus to Wheeljack about Miko.
"Yes sir."
―Miko to Ultra Magnus.

Miko met up with Ultra Magnus when Ultra Magnus saved her, Bulkhead and Wheeljack from Predaking. The team reunited with the others, but not with Smokescreen or Optimus Prime. Later on, after an attack on Darkmount, the team was captured and were about to be killed. Optimus returns in a new better built body and saves them. After the Autobots retreated to a new base, the team was honored for their efforts in the downfall of Darkmount. Ultra Magnus went with Bulkhead and Wheeljack to hunt for a Predacon bone. After killing several Vehicons, Miko came out of Wheeljack's chest, which Wheeljack forgot she was in there. Ultra Magnus questioned Wheeljack on bringing Miko, which led to Wheeljack having a flashback of Miko wanting to come along. Wheeljack persuaded Ultra Magnus when he told him that Miko saved his life from an insecticon called Hardshell. Ultra Magnus agreed and they went off into the cave. Miko took a rock and asked Ultra Magnus if that was a bone. He told her it wasn't and they moved on. Suddenly the Predacon appears in the cave and chases them. They were able to break away from the Predacon for a short time. Miko wanted to help fight and Ultra Magnus told her that she can help by reaching his ship to contact Optimus Prime. She followed his order and called him "sir", which shows Miko respects Ultra Magnus. After a short fight against the Predacon, the wreckers were buried under a pile of rocks. They were able to climb out and they went back to Magnus's ship, where Miko was in the Apex Armor fighting Starscream with his two Decepticon soldiers. The wreckers were impressed by Miko, even Ultra Magnus told Wheeljack that he wasn't wrong about Miko being brave. Eventually, Ultra Magnus and Wheeljack uncovered Shockwave's secret lab filled with Predacon clones. They destroyed it with Wheeljack's bomb, which enraged the Predacon they fought before, Predaking. Ultra Magnus and Wheeljack boldly fought Predaking in a fierce battle. In the end, Predaking got the upper hand and crushed Ultra Magnus's right hand. Luckily Optimus Prime saved Ultra Magnus and Wheeljack from being killed by the Predacon. As Ratchet worked on fixing Magnus's hand, team Prime and the humans watched.

Miko was very worried about Ultra Magnus, which shows that she cares about Magnus like she does with all her friends. Ultra Magnus is like an adult figure and friend to Miko.


"We haven't had somebody new here since Wheeljack."
―Miko excited to meet Smokescreen.

When Smokescreen was introduced to the humans, Miko was very thrilled to meet him. Smokescreen did question on if they were the lifeforms they are suppose to protect and asked if they are all like Miko. Ratchet told him that Miko was just Miko. When Smokescreen tried to encourage Bulkhead that he was battle ready, Miko gave Smokescreen a thumb's up.

Although they barely interact, Smokescreen and Miko are good friends.


Scrapheap Ratchet, Bumblebee, Bulkhead and Kids

When Ratchet told the kids that the ground bridge also works for humans, Miko suggested that they should visit her parents in Tokyo and Ratchet told them that he could send the three of them there right now but Miko walks up to Ratchet and told him to watch it. Even though Miko considers Ratchet a control freak in Masters and Students, Ratchet still thinks Miko and the others should have recieve the highest honor on their planet.

Although Miko is often a constant headache for Ratchet because of her reckless behavior, Ratchet is concerned for her safety and her feelings, such as when she was afraid for Bulkhead's life in T.M.I. and in Hurt. Miko cares for Ratchet as well and hangs with him at the base in some occasions.



"You double cross ANYONE, MINE is the face you'll never forget! NEVER!!!"
― Miko proving a point to Megatron, which comes back to haunt him.

Miko never met Megatron until One Shall Rise, Part 2. She referred to Megatron as "king con" when Megatron aided the Autobots with Unicron's manifestation over a comm link that Ratchet enabled at the base for the humans to hear. After Raf ran out to confront Megatron in the base, Miko vowed to make Megatron regret if he double crossed any of her Autobot friends in their mission to put Unicron to stasis. In Hurt, Megatron was shocked to learn that Miko had killed Hardshell.


"Big whoop. I snuffed Hardshell."
―Miko shuts down Starscream with a clever comeback.

Miko met Starscream in Rock Bottom. Starscream taunted Bulkhead and was close to grabbing Miko until Bulkhead managed to secure her from his hands. Miko was able to take the Apex Armor in Chain of Command where she boldly fought Starscream and his two vehicon soldiers. When Starscream reminded that he terminated Cliffjumper, Miko replied that she snuffed Hardshell, which ultimately placed Starscream in his place as he retreated with his soldiers.

Knock OutEdit

"Get scrapped!"
―Miko telling off Knock Out.

Miko met Knock Out in T.M.I. where she was trying to help an amnesia Bulkhead evade Knock Out and his partner Breakdown. When Miko had accidentally sent the information out on the Synthetic Energon formula out of Bulkhead, Knock Out and Breakdown nearly tried to attack her but were forced to flee when the Autobots arrived. In Regeneration and in the beginning of Darkest Hour, Knock Out held Miko in a container as the Decepticons had kidnapped all three of the Autobots' human allies. Knock Out traded with Bulkhead in an exchange that Bulkhead gets Miko and Knock Out gets an Omega Key. Miko simply told Knock Out to "get scrapped". In Deadlock, Miko finally got her revenge on Knock Out when she punched him in the Apex Armor.


"Enjoy the shadowzone dude."
―Miko wishing Soundwave a nice stay in the dimension.

Miko rarely faces Soundwave. In Deadlock, Miko and Jack worked together with Raf's aid in placing Soundwave into the shadowzone. It worked and Miko told Soundwave (even though she couldn't see him) to enjoy his time in the dimension.
