Germatoid
The Death Busters (デスバスターズ, Desu Basutāzu?) are a group of antagonists in the Sailor Moon metaseries. They are the primary villains of the third story arc, called Mugen (which means "Infinity") in the manga and S in the anime. In the English dub, they are alternatively called the Heart Snatchers and the Bureau of Bad Behavior.
The goal of the Death Busters is the resurrection of Mistress 9 in order to bring the alien creature Pharaoh 90 to Earth, which would wipe out all life in an event known as the Silence. The group is led by Professor Tomoe, a mad scientist, assisted by a woman named Kaolinite. They employ the Witches 5 to help carry out their schemes.
