Justice League vs. Teen Titans

Years ago, the demon Trigon gave birth to his daughter Raven with the human Arella. When Arella discovered his demonic nature, she ran away and was taken in by a group of mystics who lived in another dimension called Azarath. As she grew older, Raven wondered about her father. She attempted to use her powers to learn more about him. Trigon used her probe to find and destroy Arella along with Azerath and all its inhabitants. Raven managed to imprison Trigon inside a magical crystal in what was left of Azerath. Sometime later, she met and joined the Teen Titans.
