Me and my friends have begun collecting Heroclix which is a collectable mineatures game like Mechwarrior or Mageknight, but with comic book characters instead. It's pretty cool. I thought I'd mention it here since Antihero for Hire is, more or less, a superhero comic.

Also, there's a lot of powers in Heroclix that fit Shadehawk very well. Leap/Climb for his zipgrappler, Ranged Combat Expert and Energy Explosion for the gun, Outwit for when he's down on his luck (like he currently is due to a certian giant robot gremlin)
