The Phoenix Saga (4): The Starjammers - S3-E6
Plot hole: Corsair takes out the X-Men by having Raza calibrating their stun weapon to humans. Since Corsair is also a human, the blast renders him unconscious along with the X-Men, and the Starjammers take him away. When Wolverine and Phoenix regain consciousness, they realize that Cyclops has been taken by the Starjammers as well. The problem is since Corsair was unconscious, he couldn't have possibly ordered the Starjammers to take Cyclops with them, and the Starjammers had no reason to take Cyclops of their own volition. Raza even acknowledges that Corsair is the one that takes Cyclops. (00:08:15 - 00:09:00)
The Phoenix Saga (4): The Starjammers - S3-E6
Plot hole: Rogue is able to punch Gladiator and knock him off his feet, yet in the previous episode when the Juggernaut punched Gladiator he didn't even budge. The Juggernaut is a lot stronger than Rogue, so either Juggernaut's punch should have affected Gladiator or Rogue's punch should not have. (00:17:55)
