Cataclysmic monster: Oblad

Oblad was the son of a former king of hell, who leads all the evil legions to hell, and leaves the angels alone whitout any bothering. Barbatos' father, who was a king's general and the right hand, betrayed and murdered him, due to being realized that he worked with the angels. And lately, Raoul became the king. Because of this, the wars between the demons and the angels declared over and over again. But what about Oblad? He became alone, crying over his father, but with the help of Elvira, she took him with her to Heaven, in order to became Heaven's loyal warrior. After Oblad is well grown up, he heard that Barbatos' father is escaped from the prison! Which obviously means that he prepares for vengeance. But Oblad is brave enough to stop this cataclysm.
