Sludge

“Stomp your enemy, crush him under your feet.”

Likes to make presence known - a footstep can be heard and felt in a 3-mile radius. Gentle and shy, but terrifying and unstoppable in battle. Like other Dinobots, dislikes authority. Can exert 40,000 psi via feet - enough to shatter a bridge. Immense strength and endurance. Adept at fighting in water, swamp and jungle. Slow, not too clever - often victim of the calamities he causes.
