Page "Grimlock" Paragraph 35

Although content for the moment to remain a soldier, rather than a leader, Grimlock still had trouble accepting orders, only agreeing to help stem the tide of natural disasters ravaging Earth due to Cybertron being pulled into its orbit when he realized he would die if he did not.

Grimlock and the Dinobots were semi-regularly called into action when the Autobots were faced with challenges that required extra strength, such as the Sub-Atlantican invasion of Washington, D. C., or the Decepticons ' control of the TORQ III supercomputer ; with every piece of help he and his troops gave, Grimlock was never slow to add a scathing remark about the inabilities of the Autobots.

That said, he was not unwilling to admit the failings of his own troops, either, and willingly took them to the time-displaced " Dinobot Island ," where they trained in the wilderness and helped stop a Decepticon raid on the prehistoric paradise.
