Heh heh...since he opened that can of worms, I might as well give some more backstory to Raven. Please note, I didn't write this, I got it from this site, which contains a lot of info about DC characters (Cyborg's BG is pretty bizarre too):

The Titans fought Trigon twice, once in his home dimension, trapping him there, and once on Earth. That second time, he was able to release the evil in Raven, and she stood as his second as he began remaking the Earth in his twisted, hellish image (sounds like the episode the other day, huh?
)As the Titans battled on against impossible odds, the soul of Azar guided Arella and Lilith through preparing the unconscious Raven for her destiny. Raven’s soul, cleansed of her father’s evil, became a conduit through which the souls of all of Azarath came to corrupt Trigon with purity and "destroy the Destroyer of Worlds."
Raven vanished in that battle, only to reappear weeks later, amnesiac. Found by the Church of Blood, she was recruited to help him stage Brother Blood’s "resurrection" (having faked his death in an earlier battle with the Titans). In the midst of Blood’s worldwide telecast she freed herself of his influence, using her powers to release the thousands of onlookers who were under his thrall as well. Rejoining the Titans, she reveled in the emotions she was finally able to experience.
The Titans (both the team and the series) fell apart when the Wildebeest society (guided by the now-corrupted souls of Azarath) began hunting them down. Raven was killed, and the evil in her soul took possession of a new body. Though her former Titans contacts, she began implanting what she believed were the souls of her slain brothers and sisters — fellow children of Trigon whose mothers had committed suicide rather than give birth to children of evil — into people such as Changeling and Frances Kane. She accidentally implanted Raven’s true soul into Starfire, and was forced to seek her in outer space. There it was revealed that the seeds of Trigon’s children were actually pieces of his own essence, planted for his own resurrection. The Titans arrived, with Starfire carrying Raven’s soul, and Trigon was destroyed forever (again), leaving Raven as a disembodied, but again pure, spirit.
Captured again by the Church of Blood — now revealed to be Trigon worshippers — Raven’s soul was bound to the body of a teenaged girl. (The body was "...made from the sacrifices of Blood’s disciples," which might mean they created it mystically, or it might mean one of their number sacrificed her own life so Raven could take her body.) Sadly, Blood’s influence has reawakened her dark side, which Raven must again strive to keep in check.
As I said, somehow I DOUBT they're going to have that as her origin on a TV-Y7 show.
