But during their 'rampage', both Ratchet and Bumblebee try to use an electromagnetic attack to disable them. However, Sari's key gets pulled into the mix, which gives the Dinobots a small semblance of 'a spark'.

It is during this fight that Bulkhead proves to be exactly what the Autobots need to stop the Dinobots, his muscle more than a match for the Dinobots muscle.

She wants the key to get rid of her organic half that she got when she was on an organic planet infested with giant spiders. The spider's venom somehow mutated her Cybertronian systems, making her 'a freak'. After seeing how Sari's key can heal Autobots, she wants to use it to purge her organic half.

Worse, it is the work of Prometheus Black (AKA the acid-shooting Meltdown) who has forced the Dinobots to become his watchdogs, and wants to use Sari as part of his experiments to create a transforming human. His previous experiments having failed, Meltdown thinks that a still-growing human, as opposed to an adult, will have better results, and chooses Sari because he hates Sumdac. Bulkhead is injured by Meltdown and Prowl and Fanzone team up to fight Meltdown's mutant freaks (the mammal-like one was his lawyer).

To obtain Destronium to help rebuild his body, Megatron bails a fleet-footed thief named Nino Sexton out of jail and gives him Isaac Sumdac's experimental super-speed suit to obtain the Destronium for him. Since the Destronium is highly unstable it needs to be transported quickly from the research lab to Megatron directly. Megatron uses Sumdac's private bank account to make Sexton do the job. Having arrested Nino Sexton before, the Autobots are shocked to learn that he now has super speed powers, which makes Bumblebee upset that Nanosec, Sexton's new name, is faster than him. Even with a pair of experimental rocket boosters created by Sumdac, Bumblebee is unable to truly catch Nanosec. However, the Autobots make two startling discoveries: 1-Nanosec's new speed suit is making him age rapidly, and 2-their constant movements are destabilizing the Destronium which will cause it to explode and take out half of Detroit. The Autobots use their combined talents (Bulkhead's battering arm, Prowl's jump boosters and Bumlebee's rocket boosters) to launch Bumblebee into the upper atmosphere where he hurls the Destronium away before it explodes.

Soon, when the clones are freed, Starscream reveals he had planted a self-destruct bomb inside the Omegas, which will destroy everything within a 100 mile radius. Prowl and Jazz manage to piece the AllSpark together from the scattered fragments (killing Starscream in the process, by removing the piece in his head) to deflect the blast, but only when Prowl sacrifices his Spark does it come to fruition.

Ratchet thinks back to the time when he served in the Cybertronian War as a field medic. During the fighting, he was sent to rescue an Intelligence agent named Arcee who was injured during the fighting. The intelligence codes she possesses could turn the war in the Decepticons favor. For that reason, Megatron sends the the bounty hunter-for-hire Lockdown, to capture her, snagging Ratchet in the process. Back in the present, Lockdown has resurfaced and uses Ratchet's EMP generator to capture Optimus Prime. Recruited by Blitzwing and Lugnut to locate the Autobots who destroyed Megatron, Lockdown is revealed to be just a bounty hunter who doesn't care about the Decepticon's cause and just does it for the 'upgrades' he can get. Ratchet also reveals that the EMP generator Lockdown stole from him, which he used to repair injuries, doesn't work on the one bot it was designed for, namely him! But Ratchet also despises Lockdown for turning a medical tool into a weapon, and forcing him to use the generator to wipe out Arcee's memory so that the Decepticons wouldn't get hold of her security codes. But as a result, she wiped out every other memory she ever had, even of Ratchet and herself. Lockdown is apparently destroyed when his ship crashes into a bridge and Ratchet reveals to Prime that his encounter with Lockdown and Arcee is one of the reasons he is the way he is.
