Glue-Gun was part of The Conquistador's Plot in 1998.
Glue-Gun has no known powers.
Glue-Gun's equipment, as fits his name, is a high-pressure glue gun capable of firing immobilizing epoxy a considerable distance, or killing somebody from the force alone if used at extremely close range. Unlike a standard glue gun, it is fed from a tank which he wears on his back.
Glue-Gun is missing two upper teeth, possibly due to unsuccessful encounters with superheroes.
