Intro. Killdroid is an experimental prototype robotic bodyguard that was planned to be mass-produced by the Government to surveil and protect civilians. However, during one of their tests, they began to go crazy and went rogue, destroying the test site they were at and escaping into the world. The Government still does not know the cause of its malfunction, and all efforts at mass production have been destroyed. (From dying to death from Roblox!)
