X-Men: The Animated Series: Phoenix Saga, Part 2: Dark Shroud

The space shuttle crash-lands in Jamaica Bay. Though the other X-Men are unscathed, Jean Grey's fate is unknown, until she flies into the air, displaying powers and a new costume she has never used before, and proclaims herself "The Phoenix" before collapsing, suffering from confusion, memory loss, and vast new powers. Meanwhile, Xavier goes to Muir Island to recuperate after his mind is attacked and a psychic projection of his dark side attacks the X-Men; an alien named Lilandra Neramani has come to seek Xavier's help, but Juggernaut and Black Tom Cassidy kidnap her.
