A powerhouse of fighting muscle! Once rebellious,
now one of Optimus Prime's most loyal and valiant warriors. Fearsome,
powerful, virtually unstoppable on the battlefield. Thick-skinned
and stubborn. Never concedes a victory to the enemy. Partnered with
a combat-ready anti-tank cannon that fires concentrated bursts of
flaming metal. Converts to long-range mortar launcher, equipped
with 50-mile firing range. Smarter and more powerful than ever before,
Grimlock is often called to lead the charge into battle.
