Megatron has just made himself known to Isaac Sumdac and tricks the inventor into thinking that he is an Autobot. He then helps him in reprogramming some robotic dinosaurs after Bulkhead accidentally destroys them at a robotic theme park. While Sumdac tries to rebuild them, Prowl teaches Bulkhead how to 'think and move'. Behind Isaac's back, Megatron upgrades these Dinobots Grimlock (a Tyrannosaurus), Snarl (a Triceratops) and Swoop (a Pteranodon) to become his new attack drones. 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'. Megatron tricks' them into attacking the Autobots, which forces the Cybertronian heroes to battle them. 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. Sumdac thinks it would be better to dismantle the Dinobots, and Prime agrees, but Prowl, who senses a life force inside them, and Bulkhead take the Dinobots to an island in the middle of Lake Erie where they can exist peacefully.
