Professor Tomoe
Professor Tomoe is pretty much the leader of the pack. The season starts with him creating daemon eggs. These eggs are used to capture people's Pure Heart Crystals. Later we find he has a daemon inside of him, and is destroyed by Uranus and Neptune. He also has a daughter named Hotaru who is Chibi-Usa's best friend. When the season ends Doctor Tomoe decides to take his daughter and raise her normally.
