  '''Professor&nbsp;Souichi Tomoe''' is a mad scientist, and the main antagonist of [[Sailor Moon S|''Sailor Moon S'']]. He is the leader of the Bureau of&nbsp;Bad Behavior, and commands [[Kaorinite]]&nbsp;and the [[Witches 5]]. He is often called '''Dr.&nbsp;Tomoe'''.
  
  == In the anime ==
  Professor&nbsp;Tomoe was originally a good scientist and a kind and loving father, but he and his daughter [[Hotaru]] were caught in a lab explosion caused by the power of [[Pharaoh 90]], who then offered to save their lives (particularly Hotaru, who was nearly killed) in exchange for serving him. From here,&nbsp;Tomoe was possessed by the evil demon, [[Germatoid]], and became evil. Germatoid's face was visible in Tomoe's right eye, which he entered. Tomoe chose Hotaru to be the host of [[Mistress 9]], whom he was working for when she entered Hotaru.
  
  Tomoe and his assistant Kaorinite began seeking out Pure Hearts, but Kaorinite's plans kept on being foiled by the Sailor&nbsp;Scouts, until she was killed by&nbsp;Sailor&nbsp;Uranus. Tomoe brought her back to life and sent [[Eugeal]]&nbsp;to extract Pure Hearts, while inventing a Heart Santcher oven to create [[Daimon Heart Snatcher|Daimon Heart Snatchers]]. After many failed attempts, Eugeal was defeated by&nbsp;Sailor Moon and killed by [[Mimet]], who then took her place. With the Purity Chalice&nbsp;found, Tomoe needed to get it and to&nbsp;get more Pure Hearts for Mistress 9 to increase her power.&nbsp;At one point,&nbsp;when&nbsp;Tomoe was out of the lab, Mimet crammed the oven full of board games, creating a monster named [[Ikasaman]]&nbsp;who warped the house leaving Rini and Hotaru trapped inside, and Tomoe ironically was counting on the Sailor Scouts to rescue Hotaru.
  
  After [[Mimet]], [[Telulu]], [[Byruit]], [[Cyprin]], and [[Petirol]]&nbsp;were killed, Kaorinite captured Rini and Mistress 9 took her Pure Heart and used it to return to her true form, killing Kaorinite. Tomoe was sent to destroy Sailor Neptune and Sailor Uranus when they entered the base, Mugen&nbsp;School. Germatoid left Tomoe, but was killed by&nbsp;Sailor Uranus with the Pure Heart Saber. From here,&nbsp;Tomoe was no longer evil, and tried to get Hotaru back to normal, protecting her from&nbsp;Pharaoh 90's attack. Eventually, Hotaru returned to normal,&nbsp;destroying&nbsp;Mistress 9&nbsp;and turning into&nbsp;Sailor&nbsp;Saturn, and Sailor Moon destroyed Pharaoh 90.
  
  Tomoe survived the battle, and took it upon himself to raise Hotaru, who was reborn as a baby from the battle. For a time, he has amnesia and is in a wheelchair (as his arm and leg are damaged and possibly broken), but according to the doctor, makes a full recovery.

  == Trivia ==
  
  
  
  *Professor&nbsp;Tomoe is similar to&nbsp;[[Prince Diamond]], as they have a similar appearance and are the main antagonist who is being manipulated by a greater power.&nbsp;The difference is, Diamond is killed while Tomoe survives.
  *Professor Tomoe and Kaorinite make an appearance in the final episode of ''[[Sailor Moon R]]''.
  *In Episode 27, ''Thorny Weather'', when&nbsp;Tomoe is in the lab (his face shadowed) and Rini is ringing the doorbell, it appears as though&nbsp;Tomoe is sticking up his middle finger (and he is currently standing in front of his boss, Mistress 9).
