Wolverine
I wanted to do New X-men Wolverine and these parts really fit. Now technically I still need to do the yellow piping on the jacket and sleeves, but I really like the way he looks as is.
I also modified his nose a little bit to have that sort of broken nose look that Frank Quitley (sp) tended to draw him with.
ROC Joe torso (I think the Snake-eyes), arms IJ Mutt, Jacket CP Hannibal, legs WATXM cartoon Wolverine.
Mentallo
For some reason I have always really like this character although I don't think I own a single comic with him in it (beside the OHOTMU).
Cyclops head, Dr. Strange arms and torso, hands Black Bolt, legs Ghost Rider, belt GI JOE
Doombot from Avengers A:I
The break out star of Avengers:A:I is the Hank Pym reprogrammed Doombot.
A true spare parts custom- Head and arms Deep-Sea Ironman, torso, Iron Patriot, legs Ultron, feet, some Joe figure.
Lots of sculpted details--the hood isn't as nice as I'd like. It was the last of some greenstuff that was starting to dry out.
