Revealing mistake: When Pierre says "You're only extending your fate, my Cherie, and not even by that long", the shot cuts to Alexis, shown from the side of her face. In the background, Crowler and Sheppard can be seen sitting in the seating area, but their bodies don't appear to be aligned with the seats and are shown passing onto the seat next to them. (00:14:02)
Duel Distractions: Part 2 - S1-E37
Continuity mistake: When Tania shows Jaden the Amazoness Arena card, the two fingers she has pressed against the front of it are positioned at an upright angle. It then cuts to a close-up shot of the card, where the two fingers are at a rotated angle. (00:08:12)
Duel Distractions: Part 1 - S1-E36
Continuity mistake: A woman walks into the classroom holding an abandoned bag. When Banner asks "May I help you", the woman's hands are positioned outside of the straps, but when the shot cuts, her hands are inside of the straps. Also, during the shot, she has her right hand off the bag, but when it cuts to a close-up of the bag, her right hand is suddenly holding onto it. (00:04:35)
Continuity mistake: When everyone is walking in the hallway, Chazz takes out his Ojama Yellow card. He is holding it with two fingers, but when it cuts to a close-up of the card, Chazz's fingers cannot be seen holding it. (00:06:10)
Continuity mistake: When Chazz is ranting in his room, in the shot where Ojama Yellow comes out of his deck, the deck of cards shown on his bed is positioned at a rotated angle. A couple seconds later, when he says "If you want to see pressure" to Ojama Yellow, the deck of cards is now no longer positioned at an angle. Then, later in the scene after Syrus tells Chazz his door is way over there, the deck of cards is further down the bed. (00:00:12 - 00:00:43)
Field of Screams: Part 2 - S1-E32
Continuity mistake: When Chazz is looking over his cards in his room, his hands are folded, and the cards are on the bed. Ojama Yellow then appears and Chazz doesn't move his hands, but when the shot cuts, he is suddenly holding some cards in his hand that is suddenly raised. (00:04:30)
Character mistake: The episode opens late at night when Syrus overhears Banner on a call where he discusses burying Jaden alive. The next morning is a classroom scene where Banner says the field trip will take place on Saturday at 7am, and the next scene shows Jaden, Syrus, Chumley and Alexis outside the school at 7am waiting for Banner to arrive. In this scene, Syrus tells Jaden he heard Banner talk about burying Jaden alive the previous night, but by this point, at least two nights must have passed. (00:03:48)
Continuity mistake: When Chazz's brothers are speaking with him in the locker room, in the shot where one brother says "Now it's your turn, bro", there is a yellow bag and blue bag shown in the background. The yellow bag has one strap sticking upwards, and one strap bent to the side, but two shots later, both straps on the yellow bag are sticking upwards. (00:05:13)
Continuity mistake: After Belowski introduces himself to Jaden, Winged Kuriboh comes out of Jaden's deck. When this happens, Jaden's left hand is away from his knee, but when the shot cuts, his left hand is suddenly placed on his knee. (00:04:33)
Continuity mistake: After Crowler has thrown the chickens into the other vault, there are chicken feathers spread out on the floor beneath him. Two shots later, the feathers are suddenly closer together. (00:00:57)
Other mistake: When Jaden switches Oxygeddon to Defence Mode after using Spark Blaster, a display appears which shows the monster's defence points. However, the word ATK (meaning attack points) is shown on the display, even though it should read DEF (defence points) as the monster is currently in Defence Mode. (00:14:56)
Continuity mistake: After Jaden realises Blair is a girl, there is a shot of Zane's room from above where Blair starts to run away. In this shot, some of Zane's cards can be seen on the floor after they were dropped. A couple seconds later, when Zane looks at the floor, the cards are now in different positions. (00:04:47)
The King of the Copycats: Part 1 - S1-E18
Continuity mistake: When Jaden, Bastion and Chumley regroup after searching for the card thief, in the wide shot, Bastion is standing 45° perpendicular to Jaden. In the next shot, Bastion is suddenly 90° perpendicular to Jaden. (00:09:20)
Continuity mistake: Whilst everyone is waiting for the sandwich thief to arrive, Jaden and Syrus are playing cards. After Jaden correctly guesses Syrus' card, Syrus says "Picking cards, drawing cards, amazing", and has his right hand ahead of his left hand. When the shot cuts, his left hand is suddenly ahead of his right hand. (00:03:07)
Character mistake: When Chumley falls off the tree and his cards fall on the ground, Jaden picks up one and comments "There's like, a zillion koala cards down here" when he looks at it. However, all the other cards on the ground are face down and he only looked at one card, so there would be no way for him to know if there were a lot of koala cards. (00:03:58)
Duel and Unusual Punishment - S1-E7
Continuity mistake: After Syrus' life points go down to 2600, Jaden places a card face down. The card is positioned directly behind Elemental Hero Avian. But a minute later, after a brief conversation between Chumley and Alexis, the face down card is now more to the left and is positioned in between Elemental Heroes Avian and Sparkman. (00:09:13 - 00:10:26)
Duel and Unusual Punishment - S1-E7
Continuity mistake: When Chumley is standing on the cliff, Alexis approaches from behind. When he hears her, he turns his head around to face, while his body remains facing the edge of the cliff. In the next shot, he has suddenly turned around entirely to face Alexis. (00:05:45)
Continuity mistake: Jaden activates the spell card Mirage of Nightmare, and then places two cards face down. Later in the scene, Jaden activates the trap card Mirror Force, so when that leaves the field, only one other card is face down on Jaden's side of the field (not counting Mirage of Nightmare). But a couple of seconds later, when the Shadow Duelist brings Terrorking Archfiend back to the field, Jaden has three face-down cards, even though he should only have one card face down and one card already activated. (00:02:12 - 00:03:36)
Continuity mistake: When Jaden tells the Shadow Duelist to leave his friends out of this, he draws a card with his right hand. When he does this, his left hand is lowered, but when it cuts to a close-up of the cards in his hand, his left hand is suddenly raised to be level with his right hand. (00:14:00)
Revealing mistake: After the Shadow Duelist summons Infernal Queen Archfiend, Jaden says, "An Archfiend monster?" and the shot cuts back to the Shadow Duelist saying with that card on the field, every monster with Archfiend in its name gain 1000 attack points. In this shot, take note of the cards he is holding in his hand. He only appears to be holding onto two of the cards, but every other card in his hand appears to be held perfectly fine despite him not holding onto them. (00:12:41)
