Belzei Gertrude (ベルゼイガートルード Beruzei Gātorūdo?) is one of the Seeds of Darkness to have been created by the Evil King after the first time Cure Black and Cure White defeated him. He is the leader of the three Seeds, and apparently the strongest. His main color is purple, and he gets rather irritated with Regine and Juna sometimes. His human alias is Yuuki Hidehiko (ゆうき ひでひこ Yūki Hidehiko?).
