Continuity mistake: When everyone returns to the real world, Jaden stands up after waking up. There is then a close-up shot of his foot where Winged Kuriboh is shown on the ground that wasn't there in the previous shot. (00:19:40)
Continuity mistake: When Jaden draws Winged Kuriboh from his deck, he has two fingers pressed against the back of the card. Then there is a close-up shot of the card, where Jaden doesn't move his hand, but when the shot cuts again, he only has one finger pressed against the back of the card. (00:02:45)
Continuity mistake: After the guards have walked past Jaden and the woman, Jaden remarks "What's going on here" and the woman can be seen standing right next to him. The shot then cuts to focus on the woman and Jaden cannot be seen beside her, even though he was just right next to her. (00:08:30)
Continuity mistake: After Syrus explains to Jaden the call he overheard Professor Banner having, Jaden tells him "This is starting to sound like another chilli sauce nightmare" and has his hands at his side. In the next shot, Jaden's hands are suddenly grasping his backpack. (00:03:58)
Continuity mistake: When Jaden is watching Chazz give himself the prep talk in front of the bathroom sink before the duel, in a shot shown from above, there is a blue tile and a green tile shown on the top right-hand side of the mirror he is standing in front of. Two shots later, the tiles are suddenly further down the wall. (00:06:25)
Continuity mistake: After Bastion tells Jaden duelling is about being the best you can, there is a close-up of him raising his Water Dragon card to him, which is followed by Syrus raising his Power Bond card to him. In this shot, Syrus has his thumb placed over the front of the card. But in the next shot, his thumb is along the side of the card. (00:03:38)
Continuity mistake: After Jaden leaves the Obelisk Blue dorm, he says "What until I tell the guys about this", and Blair pops up her head up from some bushes she was hiding behind. The shot then cuts to a closer shot of Blair, and the bushes around her have changed shape. (00:05:58)
Continuity mistake: When Jaden starts climbing up the tree to follow Blair into the Obelisk Blue dorm, in the first shot of him climbing the tree, the branch leading toward the balcony is only a few feet long. Then there is a quick fade edit, and the branch is suddenly much longer. (00:03:52)
Character mistake: Jaden tells Damon that because of Elemental Hero Flame Wingman's ability, he will lose life points equal to half his destroyed monster's attack points. This is incorrect, as Damon will actually lose life points equal to the full attack points of the destroyed monster. He has used this card multiple times throughout the series, so this isn't a mistake he should have made. (00:18:25)
Plot hole: To escape from the students chasing after him, Damon jumps from a high ledge in the Duel Academy building and lands in the forest. Then he swings across vines at great speed, but somehow, the students all end up ahead of him in the forest, even though they were walking on foot. (00:05:30)
Monkey See, Monkey Duel - S1-E13
Continuity mistake: After Jaden summons Sparkman to the field and says "Monkey see, monkey do", the shot cuts to Wheeler, before panning over to Jasmine lying on the tree. When the shot cuts to a closer angle of Jasmine, her right hand is suddenly touching onto a branch, even though it wasn't in the previous shot. (00:08:49)
Plot hole: After discovering the cards tossed into the ocean at the docks, Miss Dorothy goes to Jaden's dorm to alert him of this. There was no real reason for her to go to him, seeing as how she had no idea if this incident was tied to him specifically. (00:09:05)
Continuity mistake: When Jaden and Syrus are sitting at the Ra Yellow cafeteria with Bastion, in the shot where Jaden says "Well you deserve it", both he and Syrus have knives and forks in their hands. But in the next shot, the utensils in their hands have disappeared. (00:07:10)
Continuity mistake: When Bastion opens the door to his dorm room to let Jaden and Syrus in, the bag he is holding has a baseball bat sticking out of one side of the bag. A couple seconds later, after Jaden and Syrus have the formulas on the wall, in the shot where Bastion says "Most of these I've memorized", the baseball bat is now sticking out of both sides of the bag. (00:05:40)
Continuity mistake: Jaden picks up a card Chumley dropped from the tree. When he picks it up, the card is pointed downwards, but when the shot cuts, the card is pointed upwards. (00:03:58)
Duel and Unusual Punishment - S1-E7
Continuity mistake: On Syrus' second turn, there is a close-up of the cards in his hand. In his left, we can see five cards and Steamroid and Gyroid are the fourth and fifth card on the right-hand side. A few minutes later, after the flashback to grade school, when Syrus activates Polymerization to fuse the two monsters together, they are now the first and second card in his left hand, on the left-hand side. (00:10:32 - 00:14:15)
Duel and Unusual Punishment - S1-E7
Other mistake: In the close-up shot of the cards in Jaden's hand on his second turn, it is revealed he drew Elemental Hero Clayman from his deck. The Clayman card is shaded orange, but since Clayman is not an effect monster, it should be shaded yellow. (00:08:26)
Duel and Unusual Punishment - S1-E7
Continuity mistake: On Jaden's second turn, he draws a card from his deck with his right hand, which is higher up than his left hand. Then there is a close-up of the cards in his hands and both his hands are suddenly level. (00:08:25)
Duel and Unusual Punishment - S1-E7
Continuity mistake: At the start of the duel, just after Jaden draws his first card, his right hand is positioned higher than his left hand. When the shot cuts, both hands are level. (00:06:25)
Continuity mistake: When the shadow dome shrinks down and disappears, Jaden puts his left hand on the coffin that Alexis is in. When the shot cuts, he suddenly has both hands on the coffin. (00:18:57)
