Life Transformer Gun

The Life Transformer Gun is a device used by Shredder in the 1989 video game. It de-mutates and instantly kills the Turtle that the player controls. He also takes away roughly half of the player's health if he is touched. After he is defeated, the Shredder turns into a pile of ash and the Life Transformer Gun is used to turn Splinter back into amato Yoshi.

In the 1989 arcade game, Shredder has access to a similar attack where he shoots an energy beam from his that instantly kills any player it hits by causting them to de-mutate into a regular turtle.
