A "Laser gun" is a type of weapon primarily based on a shotgun used by various people around the galaxy. It made It's first appearance in "The Good Deed".
From the only variation seen in the series, it is primarily similar to a shotgun. However, the scope of the gun is surrounded by three red or blue rings and a red/blue sphere.
Although the laser guns were not shown hitting things often during the feud between the families, their extreme power was shown twice: Once when an accidental shot set out a nearby small village on fire, and again when Wander used one of them to destroy the snowy part of Graknor's mountain, in order to solve the aforementioned problem.
