Death Ray Blaster
The Death Ray Blaster was a major weapon of Spaceman Spiff's. He frequently used it on his travels to fight aliens, though for whatever reason it never actually killed them.
He also used a flare.
The Demise-o-Bomb was featured only once in Spaceman Spiff: Interplanetary Explorer Extraordinaire!. The Demise-o-Bomb was supposed to have killed the Naggon, but it only stunned it. The Demise-o-Bomb was analogous to Calvin throwing a blue water balloon at his mother.
