Page "Grimlock" Paragraph 44

In the year 2011, the Decepticons invaded Cybertron in full force.

Grimlock was deployed by Wreck-Gar to fend off the invaders.

He was seen fighting alongside his fellow Dinobots as well as the Throttlebots against the invading Decepticons, however, they didn't fare too well against the Decepticon Headmasters, as they are all quickly put to sleep by Mindwipe's hypnosis attack.

In the second episode, Grimlock was again in action, trying to protect Vector Sigma alongside with two fellow Dinobots and Jazz.
