Prowl acted as go-between for the civilian High Council guards and various city-state militas. He allied with Optimus during Megatron's attack on Praxus. During the siege of Iacon, Prowl informed Optimus that Megatron was aboard Trypticon Station. Optimus feared Megatron had found a new weapon. Alpha Trion asked the Autobots what they knew about energon. Prowl tried to silence Jazz's jokes as he felt anything the Archivist had to say was significant, but even he laughed when Jazz felt Alpha Trion had not sufficiently explained what Energon was when he said it was the emanation of Primus. Alpha Trion then adequately explained Megatron had found Dark Energon, the emanation of Unicron. Optimus ordered Prowl to lead a guerilla team to draw out the Darkened Decepticons, to waste the resource in chases, when Prowl received a communication from Starscream requesting a meeting. Prowl offered to go meet him in case it was a trap, but Optimus requested Starscream speak to him on a secure channel instead. When the Darkened Decepticons stole the Plasma Energy Chamber, Prowl helped fight them off and got Ratchet to repair Omega Supreme, whom Megatron almost killed. Afterwards, Prowl received a distress signal from Sentinel Prime. He traced it to Kaon, as he recognized the signal blocking its source was used by gladiators to hide messages they didn't want on the Communication Grid from his pre-war days working in the Hydrax-Badlands circuit. Prowl rescued Sentinel with Optimus and Jazz. While recovering, Optimus went to Cybertron's core to purge its Dark Energon corruption and returned declaring Project Generation One. Prowl became part of the Eight Track crew, boarding Trypticon and sustaining heavy damage battling its drones and Minicons. He helped destroy its Dark Energon Facility, causing it to crash into the planet. He boarded the Ark with the other Autobots, journeying through the last space bridge to a spiral galaxy. Then Prowl detected the AllSpark.
After passing through the unstable Space Bridge, Prowl and the Autobots aboard the Ark found themselves in the vicinity of a Cybertronian colony world called Velocitron. They located it in part thanks to a mysterious starmap projected outwards from Optimus Prime's chest by the Matrix itself. Prowl was assigned to Hound's second response team, as Optimus Prime made planetfall with his initial squad. It was a time of great stress between Velocitron's rulers, Override and Ransack, and the Autobots' arrival from mythical Cybertron only exacerbated the situation. Worse still, Prowl uncovered evidence of a Decepticon agent on Velocitron. He overheard a secret meeting between a mysterious robot called "777" and several Velocitronians, spreading Megatron's message of "Peace through tyranny". Prowl was unable to get a good fix on 777's face or voice, but after active sabotage temporarily disabled the Ark, he came to the conclusion that one of their crew was actually a Decepticon agent. Jazz and Prowl conferred with Optimus about the situation, but ultimately concluded there was little they could do at the moment other than remain on guard. Although the Autobots secured an ally in Override, they left Velocitron on the brink of civil war during their departure, as Ransack's followers had been corrupted by the Decepticon rhetoric spread by the Ark's traitor. The next leg of their journey through the Space Bridge brought the Autobots to fabled Junkion, a world composed entirely of space junk. Prowl was on board the Ark during the initial landing again, and was therefore present when the engines blew out in another act of deliberate sabotage. At Prime's request, he kept an optic on the shifty Junkion named Axer, whom even Junkion Leader Wreck-Gar didn't trust. Prowl got some intel on Axer from another Junkion named Shearbolt, and learned that not all Junkions were natives—some came from Cybertron and other worlds, and Axer was among the most recent arrivals. Shearbolt seemed to be holding something back, and so Prowl resolved to keep both him and Axer under observation during their time on Junkion. Unfortunately, Shearbolt disappeared soon afterwards. And when Prowl eventually located the Autobot—dead and stuffed inside a starship belonging to Axer—Ratchet confirmed via energon decay that Shearbolt had been dead BEFORE Prowl supposedly had a conversation with him. Shocking as it was, this confirmed the existence of a mythical "Shifter", one of the descendents of the Thirteen's trickster, Amalgamous Prime. Tracking down Axer, he confirmed that the Autobot they thought was Hound was actually a Decepticon shifter named Makeshift. After securing Makeshift, Prowl and Ironhide oversaw the repair work on the Ark while Optimus Prime finished up his Matrix-driven quest on the other side of Junkion's Space Bridge. Makeshift's Decepticon comrades found them, however, forcing Prowl and the others to square off against the Seekers while waiting for Prime to return. He eventually did, and the situation became a bit too esoteric for Prowl's taste...multiformed legendary figures and weapons out of myth threatening to tear apart the planet. The situation resolved itself once Prime got a heading for the AllSpark in a flash of insight. Unfortunately, Megatron shared that insight, and the two Cybertronian forces began a race to acquire the prize.
