Adonis was born with a bad mother. She gave him a cursed amulet in hopes that it'll possess him, and it did. It made him do terrible crimes. Eventually he found out the spirit's name was Arion. He later hung himself. In the Underworld, Arion got his body back, and fought Adonis. They fused and Adonis eventually became evil. After he met Cepheus, they captured Gamma to bring Beta and Alpha. When they fused and lost to Lambda, Adonis would become Aria's rival.
