Bonebreaker was the former leader of the criminal cyborg gang known as the Reavers.
The Reavers are best know for their stint in the pages of X-Men during the X-Men's time in the Australian outback.

Bonebreaker himself is not only a heavy weapons expert, but a heavy weapons platform as well. His lower half has been removed and replaced with a tank like set of treads that carry an abundance of weapons.

Bullseye donated his upper body to the cause of creating Bonebreaker. He features a sculpted mohawk and custom removeable shades cut from some plastic packaging and a harness made from a metal ring and bits of rubber door seal. His harness is a separate piece and not directly attached to his body!

His treads were a 1/32 scale tank, sorry I don't recall the model. The turret was removed and his connection stalk was installed. Additionally, an articulated (2 rotating joints!) disruptor cannon sits over the back of his treads.

His connection stalk is made up of parts from an old recharge stand from Heroes Reborn Iron Man. Even the hoses are articulated. His cyber-spine is a bit of movie Doc Ock tentacle. Man those tentacles are useful!

With the removeable shades, moving weapons arm, extra guns and the ability to disassemble into his component parts, he's got a lot of play potential.
