Sludge

From Transformers Fanon Wiki

Sludge is the team’s “muscle”, could such a term be used for mechs larger than standard Transformers. He is possibly stronger even than Grimlock, but is not as proficient at utilizing his full potential as the Dinobot leader. Not too bright, and well aware of it, Sludge is content to being a subordinate, following orders without question. He is, however, very proud of being part of an elite team of robots, and is always looking for ways of improving himself, and endearing himself to his leader.

He is armed with an electron blaster and an energo sword, though he prefers the former.
