Grimlock is the most fearsome and powerful Dinobot.
Although dedicated to the Autobot cause, he resents authority. He
is a valiant warrior, but is also cold and merciless with contempt
for the weak, including all humans. He has great strength and his
jaws can break almost anything in two. He carries an energy sword
and galaxial rocket launcher in Dinobot Mode. Other than arrogance
and lack of speed, he has no real weaknesses.
