Continuity mistake: When Chumley hands Jaden his duel disk, Jaden puts it on and his deck of cards cannot be seen inside it. Jaden then walks over to face the Shadow Duelist, where his deck is suddenly inside the duel disk. Then a few seconds after that, he puts the deck of cards in the duel disk. (00:12:13)
Revealing mistake: When Jaden says "I got a whole army of vicious army of monsters in my deck just waiting to get at you", a small animation glitch occurs in the bottom right corner of the frame. Just as he begins saying "waiting", he moves his left arm slightly, and part of the red colouring on his blazer disappears from shot, almost as if the animators forgot to colour it in. (00:15:27)
Revealing mistake: When Jaden says he's started hearing voices again, it cuts to a close-up of a flashback showing Jaden holding the Winged Kuriboh card. The shot appears to be flipped as the LIGHT symbol on the card, as well as the illustration of the card is reversed, compared to every other time this card is shown. (00:03:20)
Continuity mistake: After Jaden has picked up the Level 1 card, in the shot of Syrus saying to Jaden he really lucked out, there is one card on the table in front of Chumley. A couple seconds later, when the shot focuses on Chumley and Syrus after Jaden begins the story, there are suddenly two cards in front of Chumley. (00:02:29)
Continuity mistake: After Jaden's life points have gone down to 1000, in the shot of Chazz saying, "Having some test anxiety", his arms are pointed down toward the ground. When the shot cuts to focus on Jaden, his arms are suddenly raised. (00:15:20)
Continuity mistake: When Jaden summons Elemental Hero Clayman to the field in defence mode, another version of the card appears beneath Clayman for him to kneel on. The card is shaded yellow, but around a minute later, the Clayman card is suddenly shaded orange. (00:10:14 - 00:11:09)
Continuity mistake: When Crowler reveals the rare cards in his jacket, on the top row, there is a spell card with an orange hammer on the illustration (This card is called Hammer Shot). There are then a series of close-ups of the card, and when the Hammer Shot card is shown in the close-up, it is suddenly on one of the middle rows. (00:08:10)
Continuity mistake: Crowler opens his trench coat to Chazz and his friends to reveal the rare cards. The cards are displayed in the boat as three separate rows, all equally distanced from one another. A couple seconds later, in the shot of Crowler saying "What's the matter, Chazz? Don't recognise me", the top row of cards is suddenly further away from the other two rows. (00:08:10)
Continuity mistake: When Jaden draws the Fusion Gate card, in the close-up shot of the card, it is facing toward him. In the next shot, the card is facing away from him and is also held differently (so that Jaden can place it on the duel disk). (00:14:00)
Continuity mistake: When Crowler breaks the lock to the girls' dorm, the lock and the chain that the lock is placed in land on the ground. The chain changes position when Syrus runs past it later in the scene. (00:06:02 - 00:06:52)
Other mistake: When Jaden summons Elemental Hero Clayman to the field, the card is shaded orange. Clayman does not have special abilities, and monsters without abilities are shaded yellow, and monsters with abilities are shaded yellow. The card also appears to be flipped, as the attack and defence points shown on the card are reversed. (00:16:50)
Revealing mistake: When Chazz summons Reborn Zombie in Defence Mode, the monster appears on the duel field, as well as the playing card beneath it, positioned at a horizontal angle, for it to stand on. The card casts a shadow on the ground, but the shadow can be seen lifting above the ground. (00:11:22)
Tag Team Trial: Part 1 - S1-E10
Other mistake: When Jaden explains Elemental Hero Rampart Blaster's ability to Syrus and the Paradox Brothers, Jaden has Rampart Blaster attack the brothers directly. Just as Jaden says "Blast them with rampart mirage!", Elemental Hero Rampart Blaster is in defense mode somehow standing on top of the Elemental Hero Clayman card, rather than the Elemental Hero Rampart Blaster card. (00:16:10)
Tag Team Trial: Part 1 - S1-E10
Continuity mistake: Jaden fuses together Elemental Hero Burstinatrix and Elemental Hero Clayman to summon on out to the field Elemental Hero Rampart Blaster. As the monster's being summoned to the field, Jaden calls out the name and says "Beat that." As he says this, he extends his arm and the finger that is shown to be pointing is pointing slightly downwards. In the next shot, as Elemental Hero Rampart Blaster appears on the field, his finger is suddenly perfectly level with the rest of his arm. (00:15:40)
Tag Team Trial: Part 1 - S1-E10
Other mistake: After Jaden has summoned Elemental Hero Rampart Blaster, Syrus states to Jaden that Gate Guardian's attack points are 3750 and Elemental Hero Rampart Blaster's defense points are only 2500. When Syrus is stating this to Jaden, it cuts to a reverse angle of Jaden and Syrus where Syrus says "Blaster will get blasted", you can see on Jaden's duel disk, the Elemental Hero Clayman card shown, rather than Elemental Hero Rampart Blaster. (00:15:55)
Tag Team Trial: Part 1 - S1-E10
Continuity mistake: Dox asks Para to take out the Sanga of the Thunder card from his deck which Para then does. He is shown taking out the card with two of his fingers placed on the very back of the card, but from a sudden close-up of Sanga of the Thunder, it is now only one finger placed around the back of the card. (00:09:25)
Tag Team Trial: Part 1 - S1-E10
Continuity mistake: When Dox summons Kaiser Seahorse, the sea horse's spear is held in its hand, completely level. Next shot from a far distance, the sea horse's spear is now held slanted and positioned upwards. (00:07:55)
Tag Team Trial: Part 1 - S1-E10
Continuity mistake: The shot after Dox summons Kaiser Seahorse, an overview angle is shown and the Kaiser Seahorse is directly in front of Dox. Later on, after Dox summons Kazujin, the Kaiser Seahorse is now to the left of where it was originally. (00:07:55 - 00:08:50)
Continuity mistake: When Jaden is finishing off his painting of Sparkman, in the shot of him saying "It's a work of art. It's pure genius", his left hand is placed against the lower left side of the pad. In the same shot, he brushes a huge smear of red paint against the bottom half of the page. When the shot cuts, his left hand is nearer to the top of the pad, there are now paint smears are now across the top half of the page, and the paint smear along the bottom of the page has disappeared. (00:02:02)
The Seventh Shadow Rider - S1-E44
Continuity mistake: When Alexis loses the duel, she falls to the ground and there is a shot of her cards landing on the ground, including her Etoile Cyber card that lands face up. When the shot cuts, the cards surrounding Etoile Cyber have changed position. (00:12:55)
