Who needs brass knuckles?

A commission repost by Mostly posting because he has been absent for a long time now. Hopefully he's absent due to good fortune.
This requires a little bit of explanation. I have rehashed the one on the left. He's my oldest character. The first one I ever created when I was very young. I have renamed him and tweaked his backstory only slightly. 
Now I call him Repo since it suits him better. His previous job in life was simply a repo man before he was ripped limb from limb by Loco, on the right. 
Repo, 7' 4" and upwards of 570 pounds. Capable of dead lifting over two tons. He cannot be killed and he cannot be destroyed. He is stuck here on this planet until he can figure out why he was brought back from the dead. He knows time is limited and immortality is a curse of the worst sort. Among the bonuses of being rebuilt with prosthetics he has no armpits therefore doesn't stink as much.
