Peter Petruski was a genius chemist who invented a potent multi-polymer adhesive and immediately decided to use his invention to commit crimes. First assuming the identity of Trapster, he then became part of AIM's Frightful Four division.
- Paste-Gun Petruski’s special “paste-gun” fires a stream of glue (originally supplied by a canister worn at his hip). The adhesive dries instantly, can adhere to nearly any surface, and is virtually unbreakable, flameproof, and vulnerable only to ultraviolet light. He is so accomplished with the use of his gun that he can trap an opponent’s limb, jam machinery, build restraining walls, and form paste “lassos.”
