Slug

Slag (aka Slug) is the Dinobot most likely to live up to the team's bad reputation. Slag is surly, mean-spirited, nasty, and disturbingly violent, to the point where it really is a wonder he's not a Decepticon. Slag will fight anyone, over anything, at the drop of a microchip, and fight dirty. Slag enjoys nothing more than reducing his enemies to pools of molten metal with his fire-breath (and he's more than willing to include annoying Autobots on that list). He'd swim in the pools to celebrate if he could.
