Skanafel the Devourer (WOIN)

Once a mighty and noble planetar warrior, the monster that is now Skanafel was captured during a raid against forces of a powerful demon lord. Dragged into the depths of that wicked domain, he was subjected to centuries of torment and mutilation—his wings destroyed, his face torn from his skull, and his mind and soul twisted and warped by vile demonic craft into an abomination of rage, destruction, and unending hatred for all he once was. Skanafel the Devourer has become a nightmare for the forces of good, a demonstration that even the highest of beings can be broken, corrupted, and remade into a fiendish weapon.
