My thoughts for this guy is he's the result of a huge mutant pandemic, roaming an post apocalyptic city searching for other survivors to maim and dismember until he is the only one left.
All done in Photoshop CS5 - 5-6 hours or so in total. No references used.

Wow after the huge positive response to this guy I've taken some comments on board and added more. Thanks :)

I've also submitted him to alexiuss's Romantically Apocalyptic character contest: [link]
Wish him luck! (By +FAVing him here)
