Here's Grimlock's bestie as he appeared in Fall of Cybertron. Slug was made with a Beast hunters Bulkhead with some heavy modification. "Where's Sludge?" "He didn't even make it out of the caves." "Are you sure? Like, did you check?" "Uhh, no." "Tail becomes weapon!" Now, Slug has 2 Dino modes. Normal: Aggressive: Enjoy!
