I'm guessing Ned Kelly in a prototype suit of armor. Or maybe he's a Weeble and I'd tip him to see him Wobble?

Hey, I've missed you Gus.

Sorry I don't know enough about your story to figure this one out, but I can safely say I'd not want to have a head butting contest with this one.    Great drawing!  One day I will catch up on your whole story.   

No clue.  He looks like the Tin Man crossed with the Man in the Iron Mask who used to play tennis...

I gotta a good tip, don't sit on his face.

Irv Fetzler, because his robotic arm would probably hit you. 

Ha! *L*  Who knows.  But, he certainly has my shirt.  I'm afraid to get it back. 

You know, his head sort of looks like a gas tank for Ocean City Choppers, they just made one for Lance Armstrong to resemble his spiking bike hat.
