X-Men: The Animated Series: Nightcrawler

Cyclops, still in mourning after Phoenix's death, quits the X-Men and returns to the orphanage he grew up in and encounters his friend Sarah. She tells him that a wealthy man has decided to adopt all the mutant children, especially Rusty; his true intentions are to make them his army to kill all humans in order to create a world where mutants are accepted. Cyclops must stop him and save the mutant children. Cyclops returns to the mansion, and is stunned to hear that Professor Xavier's powers have found Phoenix alive and well and returned to Earth.
