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)
Coming Home - S1-E13
Plot hole: Amuro flies the Core Fighter to the refugee camp. Taking a plane to get just across a hill is already kinda a headshaker, especially with White Base being short on resources, including fuel that is an issue in this very episode.Anyway, he lands it in the middle of the camp, and the people there tell him to please hide it. Later in the episode, we see that Amuro indeed hid it, in the middle of some woods, covering it perfectly in branches and other things. How in the world did he get the fighter there and on his own did all the camouflage work on the huge thing, is a prodigy of off-camera work.
Moero! Pegasus Ryuseiken - S1-E2
Other mistake: In the ending shot of the tournament bracket showing the potential future opponents, the two saints' names are written the wrong way, as "DORAGON" and "ANDOROMEDA", instead of Dragon and Andromeda. (00:22:00)
Continuity mistake: When Yakko points to India, Africa, except for Egypt and Madagascar, is shown as one country until he points to Tunisia.
Weirdmageddon: Part 1 - S2-E18
Continuity mistake: Two guys are throwing a frisbee and it lands on the ground. In the next shot, the frisbee is gone.
Battle Scars - S1-E7
Continuity mistake: When Echo prepares to calibrate the surgical pod, he has a bandage on his head, even though the members of the Bad Batch don't get their control chips removed until near the end of the episode. (00:14:11)
'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)
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.
Land of Hold/Penny Henny - S2-E17
Deliberate mistake: When Garfield brings Jon to the broken TV, the scene's animation is still unrendered. (00:01:04)
Fruit Picking Day/Daniel Is Big Enough to Help Dad - S1-E11
Continuity mistake: The fruit on Miss Elaina's hat changes colors.
Continuity mistake: Before Charlie says to Lola "You must double-triple promise you'll never play with it", he places the rocket beside a black box. Later in the episode, when Lola attempts to get the rocket down to play with it, the rocket is now on top of the black box.
Triumvirate of Terror! - S3-E8
Continuity mistake: After revealing himself to Wonder Woman, Joker rips of his cross-dress disguise. The two halves land on the ground on both sides of him. But then when he subdues Wonder Woman with his Joker gas, he is standing in the same spot, approximately, and the torn clothing is now gone. (00:12:00)
The Sleeper Shall Awake/Where Walks the Sleeper/The Final Sleep - S1-E11
Continuity mistake: Part 3: As you see the third "Sleeper" (a giant bomb shaped like the Red Skull's head) note the position of the monocle. First it's on its right side, then its left side, and back again to its right side. (00:14:20 - 00:15:05)
Wind Chimes - S1-E9
Visible crew/equipment: In the scene where Mcduff and Johnson are trying to find water since it's extremely hot, they go Under The Bed and notice Alfred under there. Look in the background, for just a split second, you can a man walk past the from the door. It's for only a split second so it's quite easy to miss. (00:06:05)
Continuity mistake: When Daria is on the couch with her dad she's holding a mug but the next shot it's a glass. (00:15:39)
Iron Forged in Fire: Part One - S1-E1
Audio problem: When Obadiah Stane is trying to tell Tony that Stark International is in good hands, his lips are out of sync with his speech. (00:08:20)
Continuity mistake: When Chris is trying to activate Hummingbird Power, his skin is suddenly lighter than in the previous shot.
Continuity mistake: When Steven and Connie arrive in the armoury and the hand-shaped pedestal rises out of the floor, the pedestal is shaped like a right hand when first seen, but like a left hand for the rest of its screentime. (00:06:00)
Deliberate mistake: Season 2, episode 6 "Identity Crisis": When Bizarro starts decaying into the parody form of Superman, his costume goes with it; the blue fades, and even the 'S' insignia changes. Strange that superhero garments change right alongside their wearers when they suffer from an unstable genetic effect. Were the clothes cloned right onto his body, instead of sewn?
Duck/Aren't You Chupacabra to See Me? - S4-E9
Continuity mistake: Mandy is in the library working on her report. When she's working on the second page, the writing is scribble, and on top of a stack of paper. A second later, the page says "CORN by Mandy", and the stack of paper is gone.
