At some point in my Teen Titans/Danny Phantom crossover "Raven Phantom" (where Beast Boy is corrupted by having Raven's Demon Half fused with his Soul, and Raven becomes Half Ghost to save him from Trigon)
Raven travels to the Ghost Zone and trains with the spirit of Azar (the Founder and Former Grandmaster of Azarath) to learn how to use her Ghost Powers properly
whiel there, Raven is caught in a Time Portal
which sends her to a "probable" Future...one where she Failed to save Beast Boy from her Evil Demon Half, and as such...Trigon Beast MAN has become a Insane villain who killed Trigon YEARS ago, and has destroyed nearly all of the world (similair to Dark Danny/Dan Phantom from "The Ultimate Enemy") leaving many Heroes and Villains DEAD or DYING.
Raven discovers to her Horror, that this version of Beast Boy has NO TRACE of the Goodness and Nobility that his Teenaged Self once had (having been bonded to her Demon Half for so many years has Twisted his mind, turning him Completely Evil)
he was even willing to Kill Raven, despite admitting that he was once In Love with her as a Teenager.
Raven BARELY escapes this Future with her Life/Afterlife
and, comes to the conclusion that saving Beast Boy from Trigon is her Number One Priority.
Failure is NOT an Option.
Note: sketch base on a Dark Danny/Dan Phantom Pose.
