It was there, however, that the full extent of their exposure to the AllSpark's energy was revealed, as the three Dinobots suddenly came to life! The three robots were apparently left deactivated by the blast and were returned to Sumdac's lab once more.
When the Key reacted by tugging her toward her Autobot friends, she plugged it into Bumblebee's weapons systems to boost their powers, but this only resulted in the Dinobots being blasted with AllSpark energy. Thusly rebuilt, the Dinobots went on a rampage at Dino Drive, but were restrained by the Autobots when Ratchet and Bumblebee captured them in an electromagnetic field.
The remains were brought to Isaac Sumdac's lab for repair, where the disembodied Megatron took an interest in them and attempted to turn them into robotic attack drones as practice for re-creating his own body. Grimlock and the Dinobots were originally animatronic dinosaur models at the Dino Drive theme park that were badly damaged by the clumsy Autobot Bulkhead.
