|Alias|| Doc Knock |
Commander Knock Out
|Rank|| Soldier |
|First appearance||Deus Ex Machina|
|Voiced by||Daran Norris|
Knock Out is a medical officer and former member of the Decepticons. Originally, Knock Out was relocated to Earth after being summoned by Starscream to aid the damaged Megatron. Knock Out made a rival named Bumblebee. Once Breakdown was killed by Airachnid, Knock Out took a less active role for the Decepticons, in part due to his reliance on the former and resorted to using various weapons to get his point across during battle. Knock Out no longer served as an antagonist in the series, after he joined the Autobots in Predacons Rising.
Once the Autobots defeated Megatron, Knock Out claimed joining the group as they were restoring Cybertron and was knocked out by Miko in the Apex Armor and taken as a prisoner to the planet. There, Knock Out helped the Autobots while they were under siege by whacking Starscream with the Immobilizer from behind, destroying the device in the process, proving that he really wanted to join them. The team welcomed Knock Out into their side and he remained with them ever since. Knock Out also became a part of their family now.
First Appearance/Museum Heist
Knock Out was called on by Starscream to see if he can repair Megatron. Starscream chastised Knock Out for being late but he explained that it was "a long drive" to which Starscream reacted with distaste towards Knock Out's choice of altmode and wonders why any self-respecting Decepticon would choose a land altmode when he could fly. Knock Out replied that he enjoys how he looks in his current appearance. Starscream then asked if he could repair Megatron. Knock Out said that he was better at "breaking them than fixing them" but agreed to do his best.
Later, Knock Out and Breakdown interfere with the Autobots' museum heist to take the Energon Harvester. He pulled up to Optimus Prime in vehicle mode and wolf whistles at Optimus' altmode. He and Breakdown then engaged the Autobots while Soundwave made off with the Energon Harvester taken from the human children. After Starscream began using the Harvester on Energon deposits, he and Breakdown disabled each other in an attempt to stop Bulkhead from interfering. When they come to the other, Autobots show up to help Bulkhead. Breakdown asked whether they should fight, but Knock Out decided to drive away instead.
Later, Knock Out participated in human street races, one such race resulting in him driving an opponent off the road literally for scratching his paintjob. When he returned to the Nemesis, Starscream confronted him about his street racing and ordered him to continue working on Megatron, not to race again. Later, Knock Out does indeed raced again, but this time, he happened upon Bumblebee, who is racing with Jack. He attacked them, but they managed to escape. When another kid, Vince, found Jack, Knock Out took him hostage and forced the Autobots to give chase. He and Breakdown set a trap to keep the other Autobots occupied, but Optimus Prime is able to save Vince by tearing off Knock Out's door, sending a furious Knockout fleeing into the distance. When Knock Out returned to the Nemesis after the ordeal, Starscream punished him for disobeying orders, though the punishment was only cosmetic as Starscream scratched his paintjob.
Deal with Starscream
When Starscream decided he wanted to terminate Megatron by "mercifully" taking him off his life support, he made a deal with Knock Out where he would be the new Decepticon leader with Knock Out as his second-in-command. To this end, Knock Out did his best to convince Soundwave that Megatron would not have wanted to remain in a "vegetative" state and that taking him off life support was the only solution. However, they discovered Bumblebee and Arcee doing something to Megatron's body, and as they fled, they knocked Megatron's life support system off. However Soundwave pointed out they could not let Megatron die by an Autobot's hand, so Knock Out was forced to reconnect his life support. Later, he noted to Starscream that Megatron was no longer showing any brainwave activity.
He subsequently informed Starscream that he was not yet leader, but still open to the idea of being a second-in-command. When the Autobots interferred in Starscream's latest plan to recover the Energon, Knock Out assured Starscream that his second-in-command would take care of them, and ordered Breakdown to attack. However, Optimus Prime attacked from behind, and Starscream chastised Knock Out for not keeping an eye on the rear.
Aftermath of Megatron's recovery
Following Megatron's miraculous recovery, Knock Out was assigned to keep Starscream functional as Megatron punished him repeatedly for his duplicity. Starscream disobeyed his orders to simply recover, and later Knock Out saw to him as Starscream claimed he had lost his arm and it was Knock Out's fault for not checking him thoroughly. To make up for this, Knock Out suggested an upgraded limb, or else find his old arm. Starscream returned from searching even more damaged, and Knock Out pointed out that he needed to take better care of himself.
Knock Out and Breakdown were sent to steal a data cylinder which transferred all its data into Bulkhead by a laser due to Miko's clumsiness. After detecting Bulkhead in a monster truck platform, Megatron ordered Knock Out to bring Bulkhead's head. When Knock Out and Breakdown were searching through the platform for Bulkhead, who was in vehicle mode, the Autobot transformed when Knock Out was about to inspect him, then painted some of his mathematical (or possibly scientific) equations on Knock Out. This outraged Knock Out. Before he could use his chainsaw to cut out Bulkhead's head, Miko bumped herself into his head and the data came out of Bulkhead through a laser again. The data was lost in space, then Knock Out and Breakdown retreated after Optimus, Arcee, and Bumblebee came.
At a certain point, Knock Out and Breakdown were stealing Energon cubes and Arcee was in pursuit of them until the air support Vehicons came and would have killed her if Ratchet had not intervened. Knock Out claims that he saw Ratchet for the first time saying he is a new Autobot. Megatron got assaulted slightly with energon leaking out of his mouth after Ratchet punched him in the face. Before Ratchet was able to punch him again, Megatron punched the green Energon liquid out of him. Knock Out collected the liquid back into a container, then battled Ratchet while trying to decapitate him. After Knock Out aimed his circular-saw at Ratchet but, Ratchet dodged it, causing him to miss and pinned his saw to the rock-wall; when Ratchet picked up the container, Knock Out teased him in a rude tone, asking if he was going to drink it. Ratchet then remarked, "No...I'm going to destroy it!" he through it against the rock-wall, shattering and destroying the container. Knock Out gasped and stated that Megatron would have his head for his failing to collect and present the new energon. Knock Out again retreated when Bumblebee, Arcee, & Optimus came.
He reported that the Space Bridge 2.0 was almost finished and joked on how he could hear Unicron's thoughts to Airachnid. He was present when they were rendezvousing with the portal, but his Lord left and left him wondering if he was losing it. Knock Out questioned Commander Airachnid when she suggested to abandon Megatron and witnessed Soundwave taking her down. The crew was surprised to see Optimus as Orion come with Megs. Aboard the Nemesis, in the laboratory, he gave Orion the Decepticon Insignia.
Relic hunt/ Knocked out
Knock Out would become even more humiliated during the search for the Iacon Relics, as an infusion of Dark Energon caused the Nemesis to develop its own intelligence, thereby sending him and all the other Decepticons into stasis. This would be followed by a right cross to the jaw by the Autobot medic Ratchet. A chance to recover one of the relics in New York led to a fight with Arcee and Bumblebee, with the end result of Knock Out being run over by a sweeper train.  A close inspection of Laserbeak would have Knock Out frantically trying to get rid of a live grenade.  He would later be embedded inside a wall, courtesy of Smokescreen. His only real success was obtaining a Predacon bone, but not without a great deal of trouble. 
Dark Energon Experiment/ Terrorcon attack
With the return of Shockwave and his demotion to becoming his subordinate, Knock Out agrees to Starscream's plan to inject Dark Energon into the body of CYLAS, only to have him to become an Energon-hungry zombie. This in turn causes the release of Airachnid and cutting the Vehicon forces in half as they were infected by CYLAS and became zombies as well. The end result was the banishment of Airachnid and the Insecticons to one of Cybertron's moons and a severe reduction of the remaining Decepticon forces on Earth.
Due to his experiments with Synthetic Energon, and with the aid of Shockwave, and the captured medic Ratchet, Knock Out played a role in restoring the Omega Lock with the intent of restoring Cybertron and cyberforming Earth. However, he also played a vital role in the Decepticon's downfall by merely letting it slip in front of Ratchet that Megatron had set up the Autobots into finding Shockwave's lab and destroying the Predacon clones so the clones would not have a chance at destroying the Decepticons themselves, all of which Ratchet revealed to Predaking when he was at the Predacon's mercy, and then deactivated the Nemesis' shielding allowing his fellow Autobots to storm the warship while Predaking turned on Megatron. When the Autobots attacked the Nemesis, Knock Out decided that it was time to jump ship and tried to escape, but was prevented from doing so in the ensuing crossfire. In the end, he witnessed Cybertron being restored, calling it a 'lustrous sight.' When given odd looks by the Autobots seeing him, he responded with the statement of 'joining the winning team.' Knock Out was immediately knocked out by Miko, who was in the Apex Armor. Knock Out was put in a holding cell with the remaining Decepticon troops.
Predacons Rising Movie
Knock Out was held captive with the other Decepticon troops. He gave Bumblebee information on where to find Shockwave's lab. Eventually, Knock Out was freed by Starscream, which he told him that they could finally get off the ship. Starscream told them that they need to take over the ship.
Knock Out trapped Smokescreen in the wall the same way he did to him a long time ago and was present on the bridge. When Starscream announced his plans to use the warship as a way of fleeing Cybertron, Knock Out suggested they should try Earth, since Unicron was no longer present there. When Starscream yelled at him to shut up, Knock Out seemed hurt and could be seen thinking, probably about his place in the situation, as Starscream continued talking.
While Bumblebee fought Starscream over the Immobilizer, Knock Out used the Phase Shifter to take the Immobilizer from Starscream, and then whacked Starscream with it, which destroyed the relic. When Knock Out asked the Autobots if they now believe he wanted to join their cause, they have him a grumpy look in return as Bumblebee told Knock Out that they needed the relic, by using Ratchet's most common sentence: "Knock Out! We needed that!"
Regardless, Knock Out was welcomed and escorted Starscream to his cell with Arcee and Smokescreen. When Arcee asked why he turned against Starscream, he replied that even if he did help him, he would've fired him out the first airlock, which he states "Oh, and he's rude." Knock Out and the Autobots faced against Unicron's army, with their three Predacon allies. The Nemesis crashed and the all survived, thankfully. After the Predacons were pushed with their undead ancestors in the well, Optimus and Wheeljack returned with the AllSpark. After a short battle between Optimus and Unicron, Bumblebee, Smokescreen and Knock Out tried to aid Optimus. After that, Optimus trapped Unicron's spirit inside the AllSpark's container. Megatron is back in his new body and Starscream tried to bring back the Decepticon ranks. Megatron said the Decepticons were over and flies off into the galaxy.
Knock Out was present with the rest of the Autobots with Optimus Prime. Optimus told them that they have acted like true Primes and Knock Out replied by saying that he looks up to Optimus as a best role model. After Optimus sacrificed himself, Knock Out was amazed along with the other Autobots, as the Well of Allsparks began shooting sparks out. Optimus's sacrifice restored their home world and as the team watched the sparks, a red spark, presumably Optimus's spark, shines out.
Knock Out is is relatively short in height compared to Starscream (but extremely short compared to Megatron), he is more sized like an Autobot. He is bright red in color, with red accents; like most Decepticons, his optics are red. His finish is usually very shiny, as his seems to be a bit vain when it comes down to his appearance. In vehicle mode, he has the appearance of a bright red European sports car, with the inner part of his wheels painted a shiny gold color.
Knock Out is, essentially, the Decepticon's version of Ratchet. However, rather than being grumpy, Knock Out is very vain and values his own appearance above everything else, including the welfare of his patients. When he was about to abandon the Nemesis, his greatest concern was taking along his best rotary buffer. He is also shown to not like losing that much.
He is constantly arguing with Starscream, though at times, his personality often mirrors that of the backstabbing Decepticon's and Knock Out won't hesitate to grovel or even change sides if the situation warrants it, stating that he is " joining the winning team". He considers humans as nothing but bothersome, though he does admit that they do create some 'fine-looking automobiles', as well as enjoyable fiction, such as horror films revealed that he had watched at drive-in-theaters.
Interestingly, he does seem to have some sense of morals, like when he sided with the Autobots in order to save Cybertron from Unicron. He also appears to have at least a small amount of humility. Due to his apparently humble reaction to when Optimus openly accepted him as an Autobot.
Breakdown was Knock Out's partner in the battlefield when Breakdown was alive. When on missions, they worked well together and were skilled enough to face Optimus on occassions. Knock Out was greatly angered when he found otu about Breakdowns' death and was eager to dissect the one responsible when given the chance. He showed no knowledge that Airachnid was the one who killed Breakdown, with no remorse.
While very dismissive of the Decepticon Second-in-Command, often insulting him openly. Knock Out was eager to join Starscream in his attempted takeover of the Decepticons' and become the new Second-in-Command while Megatron was incapacitated. Knock Out turned against Starscream and joined the Autobots in Predacons Rising.
The human organization won Knock Out's ire when they captured Breakdown in Russia, and attempted to dissect him in their attempts to learn about Cybertronian biology. They unknowingly angered him further when they found his remains, left by Airachnid and used his corpse save their leader Silas. Knock Out took great pleasure in torturing MECH's leader for some time, citing the Breakdown would have approved of the punishment.
Optimus Prime (formerly)
Knock Out complemented Optimus on his tires in Deus Ex Machina and attacked Optimus with his energon prod. Knock Out fought Optimus in T.M.I. and lost in battle. Optimus is rarely seen to fight Knock Out on the show. In Predacons Rising, Knock Out reveals that Optimus is a true role model to look up to.
While the pair only met recently, Ratchet proved himself more than a match for the Decepticons chief medic in both combat and scientific skill. Despite this animosity, Knock Out seemed to appreciate when Ratchet thanked him for his assistance. Earning the Autobot doctor a sincere "you're welcome". When Knock Out joined the Autobots, he seemed to patch things up with Ratchet.
Knock Out was jealous of the Autobot's newest recruit the moment they met. Noting the young Autobot had a flashier paint job, and possessed the Phase Shifter (the very relic he'd found but failed to secure on a previous mission). This animosity only grew when, after fighting Smokescreen trapped Knock Out in a wall before making his escape form the Nemesis. This eventually accumulated into Knock Out trapping Smokescreen in a wall as revenge after he and Starscream ambushed him. Despite this, Smokescreen and Knock Out are seen to reconcile after Knock Out joined the Autobots.

- Though other Decepticons in the series have shown signs of losing faith in the Decepticon cause, Knock Out is the first one to actually change sides, even with Dreadwing who gave the Forge of Solus Prime to the Autobots.
- Though the premise of Predacons Rising states that the Autobots, Decepticons, and Predacons unite as one, Knock Out is the only Decepticon who actually joins the Autobots and Predacons as Starscream was a prisoner on the ship and Shockwave dissapered.

- Like Dreadwing, Knock Out was more of a anti-hero than evil, before changing sides.
- In Thirst, Knock Out used the same line as Arcee in Scrapheap, when he was about to get his energon drained by Terrorcons, along with Starscream: " I find it rather ironic that after battling Autobots all these years, getting smacked down, shot at, blown up, this is how our lights go out? (bold= same line as Arcee)
- He is sometimes using European languages like German and French. This suits him, because his vehicle mode is an European sports car.
