Abaddon  

Prince Abaddon has large curved wings resembling a sickle and his body is covered in green scales. Despite being of royal blood, he was imprisoned in the deepest part of Hell by Astaroth after Lucifer's soul vanished. Although all who looked upon him died instantly, Kurai managed to escape his grasp by wearing one of Setunas earrings as a necklace. Abaddon recognized her as his "mother" and broke free from his chains. He later crashed Kurais wedding to Lucifer but ultimately perished while protecting her from the collapsing chapel.
