Transformers - Tempus Exitium
Bonecrusher finds beauty in rubble-strewn wastelands and longs to transform pretty much any location he happens across into one. Moreover, he makes demolition into a wild performance art. He loves to show off his destructive talents for his fellow Decepticons. Deep down, his destruction is really a perfectionism that cannot tolerate anything that he views as flawed, which includes the Autobots. Megatron values the fear and destruction Bonecrusher creates as much as the resources harvested in his wake. Now if he could just refrain from destroying buildings the Decepticons actually need…
? BCE (Before the Great War)
Megatron Origin 2 – Bonecrusher and the other Constructicons built arena sites on Cybertron for the illegal gladitorial matches. At one point, Megatron, together with Rumble and Frenzy arrived too early. There they met Soundwave who offered weapons and technology. Megatron discovered two spies, and killed them both, learning that the gladiators were hunted by the Autobots. Megatron ordered Scrapper to quit building and leave the site.
Megatron Origin 3 – As the other Constructicons, Bonecrusher makes repairs to Megatron’s gladiator team after a fight. He was there when Soundwave came in and introduced the Seekers to Megatron.
