Trapster

Peter Petruski was a chemist who was working on an extremely adhesive multi-polymar. With it he created a paste-spraying gun to commit crimes and called himself Paste Pot Pete. He battled the Fantastic Four a few times before joining forces with the Wizard, Sandman, and Medusa to form the Frightful Four. The team was defeated by the fantastic Four, but came back several times with different members.

During his time with the Frightful Four, Petruski changed his name to the Trapster, as his former supervillain name, Paste Pot Pete had been the butt of many jokes and taunts from his enemies. Trapster's paste guns could fire a variety of adhesive traps, including exploding paste balls, lubricates, swing lines, and shooting discs. He also has equipped himself with gloves and boots that enable him to climb walls and ceilings.
