Alibaba

Alibaba is the Great Child of the 5th world, Pentas. His Spirit's name is Hibana (ヒバナ, known as Spark in some dubs). Because of a curse, Alibaba turns into a beautiful and tomboyish woman at night, and turns back into a girlish man at day. His objective was to capture Baku and his friends to save Pentas from a curse.
