Weakness offends GRIMLOCK®. He considers none so weak as those who refuse to use their full strength to command victories. As a result, he's never had much respect for OPTIMUS PRIME®. He barely even considers himself and his DINOBOTS® to part of the AUTOBOT® army most of the time. He only grudgingly helps the heroic AUTOBOTS® because the tyranny of MEGATRON®offends him even more than weakness. He longs for the day when OPTIMUS PRIME makes a final mistake, leaving a vacancy that GRIMLOCK will be more than happy to fill.
