Kre-O comic
Grimlock had himself a hearty laugh when Megatron attempted to replicate Optimus Prime's new clear-torso'd power-up via a see-through negligee. Wheeljack's Bizarre Invention! Optimus Power Up!?
Grimlock was at Metroplex before it was attacked by Earth's worst criminals. The Brick List: Earth's Most Wanted
Kre-O cartoon
Grimlock participated in an enormous battle against the Decepticons... until Optimus Prime began talking about the plot of the live-action film series to the audience. He quickly grew bored during his leader's monologue and attempted to order a pizza over the phone. The beeping caused by Grimlock dialing up the pizza place kept on interrupting Optimus when he tried to spoil the plot of the fourth film. Optimus settled with introducing Grimlock and the rest of the Dinobots. Then Grimlock's pizza arrived, and the fighting started up once again. Take Us to the Movies Take Us Through the Movies
Grimlock served as Optimus's mount as the two of them burst in on a bunch of Vehicons building the Galvatron Factory Battle set. Announcing that it was "Dinner Time!", Grimlock used a sort of tractor beam to draw his victims into his maw. He also got to stomp down on Lockdown, and kicked his head away.

Grimlock went to game at the arcade, only to be infuriated over not being able to beat a particular game. As soon as he gave up the task, Fracture came along and beat the game with ease! This sent Grimlock into a rage, and he began to rampage across the arcade... until he spotted a Foosball table, and went to play with it instead. Arcade
