Grimlock helped to sniff out the "dinosaur transform static" that implicated Trypticon in the theft of world monuments. Later in the year, when Decepticon leader Galvatron had Cybertron infused with function-inverting anti-electrons, a dose of the particles gave Grimlock super-intelligence. For the first time Grimlock identified himself as "I, Grimlock". During a mission to Unicron 's disembodied head, where the Autobots were outmatched by the new Decepticon Terrorcons , Grimlock used components of Unicron's head to construct the Technobots to battle them. Combined as Computron, the Technobots felt they could not match the Terrorcons, until Grimlock transferred his super-intelligence into Computron, reverting to his old self and allowing the Technobots to claim victory.
The Dinobots took refuge with the other Autobots in Cade Yeager's junkyard . Since their alternate modes were too conspicuous, they hid themselves by digging underground tunnels and only coming out to feed. At some point, the Dinobots began reproducing through unknown means and gave birth to at least three baby Dinobots . Unlike their larger counterparts, the Mini-Dinobots spent most of their time in Cade's house. When the Deceptions found the base and attacked, Grimlock and Slug burst out of hiding to defend their offspring and Autobot friends. After the battle, the Dinobots went back into hiding with most of the Autobot refugees and did not participate in the final battle against Quintessa . The Last Knight
In their first appearance in the Generation One series, the Dinobots were dispatched to Earth to discover what had happened to the missing Ark . They encountered the Decepticons, who would become the Insecticons , and both sides blasted each other into stasis lock. The Dinobots killed Octane and stole his ship, but they ran into trouble when the local Autobot forces believed them to be traitors and fired on them. Repaired by the Autobots, who were by now convinced of their intentions, they participated in the final assault on Shockwave, where Grimlock rescued Magnus and Optimus Prime.
