Bonecrusher hates everything, and what Bonecrusher hates, he destroys. He hates this planet and all its inhabitants. He hates the Autobots for getting in his way. He even hates Megatron and the other Decepticons; the only reason he stays with them is because Megatron scares him. Bonecrusher lives for the day when he's the only one left standing atop a pile of smoking rubble and shattered robots.
