Worlds Collide: Part 3 - S3-E6
Plot hole: In their previous encounters with the Triceratons, the Turtles had to learn the hard way that the Triceratons breathe not oxygen but a combination of nitrogen and sulfur, which is detrimental to most Earth lifeforms, and thus had to wear special rebreathers. When the Turtles, Splinter, April and Casey enter Zanramon's throne room along with Traximus, none of them wear any breathing equipment to protect themselves from the hostile atmosphere.
Continuity mistake: At the end of the battle between Jaden Yuki and Gravekeeper's Chief, just as the explosion settles, in one shot you see the Gravekeeper's Spear card to the left of Gravekeeper's Chief on the duel disk. However in the next shot Gravekeeper's Spear is replaced with Magician of Black Chaos, which Chief neither has in his deck or ever played in the match. (00:13:35)
Spider's Little Daddy/Tricycle of Terror - S3-E1
Continuity mistake: Mandy's working on her report. The page she's on says "CORN by Mandy." A moment later, she writes the same title on another page.
'Unmei no sentaku' mitaina - S1-E6
Plot hole: Akito's attack is point blank, on a ship part of a fleet with Distortion Field activated (basically, they have shields, like the good guys' robots). The explosion he causes is according to Ruri's damage report big enough that it managed to vaporize 80% of the ships they were facing, but his Aestivalis and the other 3 right floating nearby make out of it literally without a scratch. (00:05:10)
Other mistake: In the scene where Yakko, Wakko and Dot are sitting at their desks repeating Miss Flamiel's every word, Wakko is drawn without legs (only feet) during one shot.
Other mistake: While Sonic and Tails are locked up in old Spelunk's cage during the cave-in, right before the huge diamondius crashes on top of the cage, there's a close-up of Sonic holding the bars, and the color of his torso becomes the same as the background mid-shot. (00:13:40)
Plot hole: White Base and the interior of Luna II withstand without a scratch the explosion of the thermonuclear reactor from the Magellan from just a few meters, while the blast literally vaporizes the Zaku far away from the entrance and threatens to damage the Musai, hundreds of meters away.
Continuity mistake: When Chris is trying to activate Hummingbird Power, his skin is suddenly lighter than in the previous shot.
Continuity mistake: The package Steve received from Mailbox is briefly visible before Mailbox comes in. You can also see a crew member's hand holding the package as Steve grabs it.
Continuity mistake: When Steven arrives on the Sun Incinerator, he's carrying a large sub (sandwich), which he gives to Lars. After the ship's power goes out shortly thereafter, the sub has vanished.
Continuity mistake: When Captain Bragg orders her troops to move in on the people in the square, GS-8 is standing behind her, despite the droid having fled the scene just two shots earlier after Senator Singh's arrest. (00:02:58)
What If... Captain Carter Were the First Avenger? - S1-E1
Deliberate mistake: When Peggy and Steve are studying the map where the 107th Army division is held captive, the names on the map are nonsensical names that do not even follow German spelling or standards for place names ("Farfignugen," "Dädtenorth," and "Rosskjhberg," for instance). Most of them are also reused, appearing several times on the same map. This is most likely done deliberately so as to avoid any resemblance to real places, but still looks out of place and illogical. (00:11:27)
Audio problem: While Pickles is sniffing the ground, she asks Bob "Did you know vomit tastes bad?", but her lips don't match what she is saying.
Triumvirate of Terror! - S3-E8
Continuity mistake: When the camera first shows Jimmy, he says "Where the heck have you been" and looks up to his left then straight forward. The shot changes to a close up and suddenly he is looking up to his right. (00:00:15)
Is Lupin Burning... ?! - S1-E1
Other mistake: The logo of the evil organization, Scorpion, contains just a little misspelling. It's missing the R. (00:02:50)
Iron Forged in Fire: Part One - S1-E1
Continuity mistake: After the plane explosion, a scene six months later is shown with Tony lying in bed with his chest piece now in that keeps him alive. The first shot shows it with some wire or designs of some sort protruding around it along his chest. Some of the ends overlap with the border of the central round piece. It then cuts to a closer view of the device as Tony’s alarm sounds, and suddenly the pieces do not overlap the circle at all, and some of them slightly change shape and position. (00:06:35)
Continuity mistake: When Lemmy falls down from the window and running away from Bowser with Iggy, Iggy's face turns orange. Then later, it turns back to green.
Revealing mistake: As Lois says she wants a chance to crack the case on her own, Clark turns his head to look at her. As he does, the shadow effects on his collar flash suddenly several times, his collar going in and out of the light rapidly on the right side. (00:03:00)
Continuity mistake: When Dum-Dum cuts the rope releasing Chug-a-Boom from the balloon, we cut to the car and you can see Clyde and Dum-Dum are surrounded by the rest of the Ant Hill Mob, but when we see the two in the next shot, the other members are nowhere to be seen.
The Sleeper Shall Awake/Where Walks the Sleeper/The Final Sleep - S1-E11
Continuity mistake: In part 3 an agent of the Red Skull tweaks a letter on a statue to activate the third and final "Sleeper." At a distance you see the statue depicts someone on horseback, one of the horse's hooves is above the ground. As the agent tweaks the letter, all four hooves are on the ground. (00:14:05)
