Ten foes of Green Arrow:
- The Bull's-Eye
- The Skylark
- Professor Million
- Stanley Dover
- The Rainbow Archer
- Clock King
- Onomatopoeia
- Morgan Thorpe
- Count Vertigo
- Slingshot
hcwoodward's desire to see onomatopoeia mentioned in a list reminded me of the comic book character who goes by that name. His gimmick is that he never speaks but to say the sound of one of his actions. So if he's about to shoot someone, he'll say "blam" first. Pretty good character, all things considered. Better than the Raibow Archer, that's for darn sure.
