I actually found a use for Doom Rider. His bike has enough other due dads on it to make it different than your regular biker. My guy is Slannesh, but here is a pic.
The skull on the bike makes a good personal icon. You can then buff him up with powerweapons or what not. My torso is the
EC champion torso, with standard biker legs that I added some green stuff to bulk them out. The tenticle can be used to represent demonic mutation or something like that.
Besides, you don't have to paint your guy orange. I think a big backpack goes a long ways to helping him look more important as well.
