The Death Busters (デスバスターズ Desu Basutāzu) are a group of fictional characters who serve as antagonists in the Sailor Moon manga series written by Naoko Takeuchi. This group comprises the antagonists of the third major story arc, which is called the "Infinity" arc in the manga and Sailor Moon S in the anime. They are first introduced in chapter #24 "Infinity 1 – Premonition", originally published in Japan on July 7, 1994. In the Cloverway English adaptation, they are called the "Heart Snatchers".
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. Their base of operations is Infinity Academy (無限学園 Mugen Gakuen), founded by Tomoe with Kaolinite being the principal.
Professor Souichi Tomoe (土萠 創一 Tomoe Sōichi) is the leader of the Death Busters and Hotaru Tomoe's father.
