When I was a kid I used to sometimes get the Superman comic (late 80's/early 90's). There was a 2nd story at the back, it might have been Green Lantern but I can't be sure. I always remember an issue set in space with a female character dressed in purple with a robot or claw hand/arm. I think she was a villian but again can't be sure. I've never been able to find any pics or name of this character and it's always bugged me! Any info would be appreciated! Thanks
