Complete Monster: Killer The Butcher is The Dragon to Big BadGaizock. During the series, this guy commits any sort of horrible action, the mildest of which is mass murder of innocent civilians with the excuse of humans being worthless. One of the crueler of his deeds is implanting mini-bombs inside unknowing human prisoners, just to release them, let them go back to their families, and then blow them up. All the while, he admires his work, is proud of the bloodshed and jokes about the horrible deaths of his victims, treating his killing sprees as a funny game.
Fridge Horror: The Big Bad Gaizok states that it is made by the Gaizok race and is numbered eighth and sent out to destroy creatures "with bad thoughts". Does this imply that it is only ONE OF THE SEVERAL bio-computers manufactured, while the others are roaming the galaxies and trying carry out their designated massacre jobs?
