diff.text: Professor&nbsp; Tomoe was originally a good scientist and a kind and loving father, but he and his daughter [[Hotaru Tomoe|Hotaru]] were caught in a lab explosion caused by the power of [[Pharaoh 90]]'s servant, the entity known as&nbsp; [[Germatoid]], who then&nbsp; offered to save their lives (particularly Hotaru, who was nearly killed) in exchange for serving him. From here,&nbsp; Tomoe was possessed by 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.
diff.text: Tomoe and his assistant [[Kaorinite]] began seeking out Pure Hearts, but Kaorinite's plans kept on being foiled by the [[Sailor&nbsp; Senshi|Sailor Scouts,]] until sheher was killed by&nbsp;Sailor&nbsp;Uranusdeath. 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 then 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.
diff.text: 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 herethere,&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 90Saturn.
