X-Men: The Animated Series: Phoenix Saga, Part 4: Starjammers

Phoenix transports all the X-Men to Lilandra's ship, where she has hidden the M'Kraan Crystal. A group of space pirates called the Starjammers attack and steal the M'Kraan Crystal from the X-Men. Phoenix reads the leader, Corsair's mind, and discovers he is Cyclops' long-lost father. The Starjammers want to trade the Crystal to D'Ken, so that they will get close enough to kill him, but they are double-crossed. Despite Phoenix's best efforts, D'Ken unleashes the Crystal's power and sucks himself, the X-Men and the Starjammers inside.
