Minotaur is the second Cardian that Alan and Ann send to drain energy. She attacks by using her horns to drain energy from her victims. She appeared in Sailor Moon R Episode 2, So You Want to Be in Pictures.

When Molly, Amy, Raye, Lita, and Mina were being auditioned for a movie, Alan and Ann attacked it and released Minotaur to drain energy from them for the Doom Tree. Minotaur drained Molly's energy before Serena transformed into Sailor Moon to fight her. However, Minotaur gained the advantage and began to drain her energy. Luna's only option was to restore the memories of the other four Sailor Scouts. They transformed and attacked her. Sailor Mercury's Mercury Bubble Blast distracted Minotaur long enough for them to get Sailor Moon away from her, and she was injured by Sailor Jupiter's Jupiter Thunder Crash before Sailor Mars and Sailor Venus destroyed her by combining their Mars Fire Ignite and Venus Crescent Beam Smash.

Her name comes from her resemblance in appearance to a minotaur.
