The Lotus and the Steel - S4-E13

Revealing mistake: The footage of Jubilee flying off in the mini-jet is recycled footage of her flying Colossus back to Russia from the season 4 episode "Red Dawn." You can even make out Colossus' silhouette in the window over the passenger seat in one shot, even though Jubilee is supposed to be by herself. (00:07:35)

Beyond Good and Evil: Part 2 - S4-E9

Revealing mistake: When Psylocke is scaling the cliffs, her left leg passes through the cliff walls. (00:09:20)

Phaneron ★

Beyond Good and Evil: Part 1 - S4-E8

Revealing mistake: When Mr. Sinister is mocking Jubilee, take a close look at his neckline as he moves his head. The animators moved his neckline as he moved his head, but his shoulders stay in place, so his head and neck look like they are floating above his shoulders. (00:15:30)

Beyond Good and Evil: Part 1 - S4-E8

Revealing mistake: The slice of cake that Wolverine cuts out already has the cut-lines animated on it before he starts slicing it. Probably to make it easier for the animators to animate his hand movement. (00:11:05)

Proteus: Part 2 - S4-E5

Revealing mistake: When Proteus is leaving his father's home while possessing the police officer, the green glow of his eyes doesn't stay in place as he is moving. You can see the green glows leave his face and float in midair with the eye slots on the face turning black. It appears that the animators couldn't keep the glowing eyes synchronized with the body movement. (00:07:30)

Proteus: Part 1 - S4-E4

The Dark Phoenix (4): The Fate of the Phoenix - S3-E14

Phaneron ★

The Dark Phoenix (2): The Inner Circle - S3-E12

Revealing mistake: When Cyclops uses his optic beam to blast Leland through several walls, the final wall that Leland goes through already has a hole in it. (00:15:40)

Savage Land, Strange Heart (2) - S3-E9

Revealing mistake: At various points in the episode, the animation for the flashing red eyes on Garokk's various statues is not synchronized with the physical impression of the eyes on the statues.

Phaneron ★

Savage Land, Strange Heart (2) - S3-E9

Revealing mistake: When Rogue is saving Jubilee and Wolverine from the stampede of dinosaurs, you can see that the dinosaurs behind them are simply gliding across the screen. (00:04:30)

Phaneron ★

Savage Land, Strange Heart (2) - S3-E9

Revealing mistake: When Beast is checking on Storm, his right foot appears under her left armpit despite the fact that she was lying flat on the ground. (00:19:25)

Phaneron ★

The Phoenix Saga (3): Cry of the Banshee - S3-E5

Revealing mistake: When Professor X is telling Juggernaut that he is in his mind, if you look closely you can see there is a disembodied mouth on the right side of Professor X's face that is synchronized with his dialogue. Apparently an animation error. Note: this error may only apply to the DVD version of the episode, as it does not occur on the version of the episode that appears on Disney+. (00:04:00)

Phaneron ★

Out of the Past (2) - S3-E2

Revealing mistake: When Beast states that it appears safe to enter the alien ship, his right arm and right leg completely pass through Professor X's body and hover-chair respectively. (00:13:45)

Revealing mistake: When Wolverine, Storm, Rogue and Gambit are walking down the stairs to the subway station, you can see that they aren't actually descending the steps, but walking on thin air. (00:11:10)
