This is the Wasp, a minor super villain and sometimes hired thug. most of the other super villains think he is a bit of a joke, but his electo-gauntlets pack quite a sting.
The mini is an old Golden Heroes Miniature called Bug Bandit, made by Games Workshop (I think) and long out of production. My mate Leon managed to get this one for me on EBay, and I am delighted with him. The scale is a bit small, but that just makes him look even weedyer (if that is a word?)
