X-Men (1992)

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

Continuity mistake: Rogue rips off Donald Pierce's cybernetic left arm, but when he is first shown running away, his right arm is the one that is missing. When he catches up with Sebastian Shaw in the secret passageway, his left arm is back to being the one missing. (00:18:30)

The Final Decision - S1-E13

Trivia: One of the images in Gambit's mind-scan is of fellow Marvel Comics superhero Ghost Rider. (00:07:45)

Phaneron

The Cure - S1-E9

Revealing mistake: When Rogue puts the dome in place, if you look closely you will see that the dome is resting on thin air (note that you can see the sky through the platform she sets it on, and when she sets it down, the underside of the dome is visible). (00:06:15)

Phaneron

Slave Island - S1-E7

Plot hole: After Storm's attempt to escape the Genoshan prison is thwarted, she ends up in the ocean right at the shoreline of the beach, where she is captured by a Sentinel. Aside from the fact that it makes no sense for a Sentinel to be hiding in the ocean in the event that a mutant tries to escape the prison, there is absolutely no way that a two-story tall robot could hide in the ocean right by the beach, as the water would be way too shallow. You can even see that the water level only goes up to the Sentinel's ankle area when it is standing upright in the ocean. (00:03:15)

One Man's Worth: Part 1 - S4-E1

Trivia: The man that aids Wolverine in the coffee shop is Johnny Strabler, Marlon Brando's character from the film "The Wild One." (00:16:45)

Phaneron

Have Yourself a Morlock Little Christmas - S4-E12

Other mistake: When Gambit is tasting the food in the crock pot, his left arm has been drawn backwards.

Phaneron

X-Ternally Yours - S2-E6

Continuity mistake: When Gambit first walks into Bobby's cell. Bobby is sitting in a chair up against the back wall. A few shots later, Bobby is sitting in the center of the cell. (00:09:55)

Phaneron

X-Ternally Yours - S2-E6

Continuity mistake: Bella Donna's engagement/wedding ring from Gambit doesn't appear on her finger until she mentions that she still wears it. (00:10:55)

Phaneron

Longshot - S5-E5

Factual error: When Rogue and Beast are playing pool, in one shot the 8-ball is colored white instead of black. (00:07:50)

Phaneron

Family Ties - S4-E17

Revealing mistake: When Quicksilver is fidgeting inside his containment shell, the animators neglected to properly sync his body movement. You can see that his shoulders are not "connected" to his arms, as if his head and shoulders were separated from the rest of his body. (00:16:00)

Phaneron

Secrets, Not Long Buried - S4-E15

Revealing mistake: When the Lady Gardener shuts her door on Cyclops, his right arm stays inside her house in front of the door frame. (00:14:35)

Phaneron

Secrets, Not Long Buried - S4-E15

Revealing mistake: Instead of staying in place, the energy surging around Watchdog's head moves down the screen as the camera pans down. (00:02:35)

Phaneron

Love in Vain - S4-E14

Revealing mistake: When Rogue's phone is ringing you can see that the phone is halfway absorbed into her mirror. (00:04:15)

Phaneron

Beyond Good and Evil: Part 2 - S4-E9

Continuity mistake: Magneto straps Wolverine to the port side of a boat and then drops the boat on a warehouse. When Gambit is freeing Wolverine, Wolverine is suddenly on the starboard side of the boat. After Gambit frees Wolverine, they are both shown to be on the boat's port side. (00:17:00 - 00:18:00)

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)

Phaneron

Weapon X, Lies, and Video Tape - S3-E19

Continuity mistake: The helmet Wolverine picks up changes from gray to gold and then back to gray when he drops it. (00:05:25)

Phaneron

Nightcrawler - S3-E18

Continuity mistake: Gambit moves further away from Rogue when they are sitting on the couch. (00:03:00)

Phaneron

The Juggernaut Returns - S3-E17

Trivia: When the new Juggernaut crashes through the film studio, the production being filmed is a parody of Mighty Morphin' Power Rangers. There is even a short musical phrase similar to MMPR's theme song. (00:16:10)

Phaneron

Cold Comfort - S3-E15

Continuity mistake: The tray of food Beast brings for Iceman has suddenly disappeared when he asks him about Lorna. (00:09:20)

Phaneron

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

Continuity mistake: When Cyclops blasts a hole in the floor beneath Sebastian Shaw and causes him to fall through it, Shaw lands on a catering table. Later when Beast jumps down the hole to attack Shaw, Shaw is emerging from underneath heavy rubble rather than a catering table, and he is inexplicably shirtless. The rubble also changes from being brown just before Beast jumps down the hole, and is then white after he lands. Additionally, the floor goes from being black-and-white checkered to a solid brown color. (00:15:55 - 00:17:05)
