Other mistake: When Wolverine is leaving to find Yuriko and Jubilee offers to tag along, the camera is fluttering in and out of focus for a few seconds. (00:07:01)
Other mistake: When Wolverine first enters the subway, there are two tracks, and there is a train moving away from the camera on the track closest to the platform. When Gambit and Jubilee enter the same area moments later, there is now a train on the same set of tracks, but moving towards the camera. (00:07:38 - 00:08:07)
The Phoenix Saga (1): Sacrifice - S3-E3
Other mistake: When Dr. Corbeau opens the door to the locker room, Cyclops, Jean Grey and Wolverine are in his direct line of sight. Despite this, it isn't until he takes several steps into the room that he realises they aren't his shuttle crew. (00:08:35)
The Phoenix Saga (2): The Dark Shroud - S3-E4
Other mistake: After the shuttle crashes into the Upper New York Bay, the X-Men escape the wreckage and swim up to the surface, with Wolverine being the first one to appear. Given that Wolverine's skeleton is coated with a heavy metal, not only should he not be the first one to surface, he should actually sink instead. (00:04:06)
The Phoenix Saga (3): Cry of the Banshee - S3-E5
Other mistake: When the text depicting the episode name appears on screen after the opening credits, it says "The Phoenix Saga Part 2, The Cry of the Banshee." It should read "The Phoenix Saga Part 3, The Cry of the Banshee." Note: this mistake may only apply to the DVD version of the episode. The episode that appears on Disney+ correctly depicts it as "Part III." (00:02:20)
The Phoenix Saga (3): Cry of the Banshee - S3-E5
Other mistake: When Xavier is telling Moira about how he and Lilandra were attacked, Moira dismisses his claim, reasoning that he came to her for help because he could no longer trust his own mind, and that no-one else had been in his room. She witnessed him flying out of a window, and he's a paraplegic. Unless she thinks he somehow catapulted himself out the window, she shouldn't have been so dismissive of his claim. Not to mention the damage to the room, including the bed being thrown against the TV. (00:05:21)
The Phoenix Saga (4): The Starjammers - S3-E6
Other mistake: When Captain Britain is shown flying by the Elizabeth Tower, the two clocks visible are displaying different times. The clock on the left is showing roughly 12:10, while the clock on the right is showing 12:00. (00:04:50)
The Phoenix Saga (4): The Starjammers - S3-E6
Other mistake: When Gambit is tossing playing cards in Lilandra's helmet, he is shown tossing four cards. All four cards are the exact same card (the ace of spades). (00:13:30)
The Phoenix Saga (4): The Starjammers - S3-E6
Other mistake: When D'Ken is saying "Destroy them all," he is speaking with a German accent. (00:17:09)
The Phoenix Saga (4): The Starjammers - S3-E6
Other mistake: When the X-Men and Corsair encounter D'Ken in the hallway, D'Ken, Gladiator and Lilandra remain in the background while the X-Men and Corsair are wiped from the screen. It's as if this was meant to be a zoom in on D'Ken, Gladiator and Lilandra, but their size relative to the camera remained the same and the X-Men and Corsair are simply removed from view. (00:19:35)
Savage Land, Strange Heart (2) - S3-E9
Other mistake: When Rogue tells Beast that the word "Zaladane" kept popping in and out of her head when she and Sauron made physical contact, a border roughly in the shape of the letter "D" appears around her mouth. (00:08:08)
Savage Land, Strange Heart (2) - S3-E9
Other mistake: When Storm is directing a surge of lightning at the monolith of Garokk after telling Rogue to stay back, the plume of smoke coming from the volcano in the background is completely motionless. (00:16:49)
Other mistake: When Apocalypse is holding Rogue upside-down, her belt remains in place despite the fact that her belt is wider than her waist and abdomen (it is not as wide as her hips which is why it remains in place when she is upright). Her belt should have fallen down to underneath her breasts. (00:11:50)
Dark Phoenix (1): Dazzled - S3-E11
Other mistake: The episode begins with an out-of-place one-second shot of a door opening on a space craft revealing a satellite hovering over Earth before quickly cutting to an establishing shot of Muir Island. Note: this may only apply to the version of the episode that appears on Disney+. (00:01:00)
Dark Phoenix (1): Dazzled - S3-E11
Other mistake: When Moira McTaggart asks Jean what happened to her, keep an eye on Banshee. His body slightly stretches horizontally for a split-second. (00:01:15)
Dark Phoenix (1): Dazzled - S3-E11
Other mistake: When Wyngarde is facing the wall after White Queen breaks his mental contact with Jean, he is casting a shadow against the wall. However, as the White Queen approaches him, she has no shadow of her own. (00:15:17)
Dark Phoenix (1): Dazzled - S3-E11
Other mistake: When Rogue is looking down at the Inner Circle from the skylight, a hair appears on the animation cel, in the glare of the glass to the left (viewer's right) of her head. (00:18:14)
