The Bonecrusher

Mac McGee (a.k.a.) The Bonecrusher is a fictional comic book supervillain and a an enemy of Gun. He was formerly a scientist until he conducted an experiment that caused a drought, wiping out half of the resouces in Spain to China. He was then locked up in an asylum in Russia. There, they conducted a test of their own, giving Jason a drug known as the Toxin-Fatigue Elixir, after being hit by a speeding car and being sent to the hospital. After taking it, he was giving gauntlets to channel the effects more causiously, enabling him to push his body through monstrous sizes of transformations. The elixir was made with the substance of the other crystal from Lazar, Cryptogen.
