A Sight Unseen: Part 1 - S3-E35
Continuity mistake: On Jim's second turn, he draws a card from his deck. When he finishes drawing, he has two fingers pressed against the back of the card. In a close-up of the card, he has the side of one finger against the back of it. (00:18:12)
The Darkness Is Revealed - S3-E34
Continuity mistake: In the flashback of Jim as a young boy, he puts a stick in a mantrap, causing it to break. The distance between his hand and the top of the stick changes between shots. (00:04:55)
The Darkness Is Revealed - S3-E34
Continuity mistake: When the episode opens on the father and son at the campfire, in the wide shot, he has his right hand on his lap. Then in the next shot, his right hand is lifted. (00:00:04)
Dueling with the Dark Army - S3-E30
Continuity mistake: After the opening titles, the scene opens on the main group standing around the bed of the man who went to the stars at the end of the previous episode. The boy is shown kneeling next to the wooden corner of the bed where the pillow is located. In a close-up of the boy's knees, he is kneeling next to the blanket. (00:01:50)
Continuity mistake: When Scarr has finished explaining the ability of Fusion Devourer, Jaden says "Me get it" with his right fist raised. When the shot cuts, his right hand is lowered. (00:08:48)
Character mistake: On Jaden's first turn, he considers fusing his Bubbleman and Clayman to summon Elemental Hero Mudballman because "he'd have enough attack points to take down the Sky Scouts' Simorgh." This is not true, as Mudballman has 1900 attack points and Simorgh has 2700 attack points. (00:10:57)
Continuity mistake: Just after Atticus says his boots aren't the best for hiking through alternate dimensions, Alexis says "Well I'm going" and looks off to the left. In the next shot, she is looking at Bastion. (00:02:35)
Revealing mistake: When the main characters are in the other dimension, they are shown walking on sand quite a lot, but they never make any footprints when walking across it.
Unleash the Dragon: Part 2 - S3-E26
Revealing mistake: When Marcel activates Dimension Fusion Destruction, whilst explaining that by removing the three Sacred Beasts from play, he can summon a new monster, there is a shot of him saying "I can summon Chaos Phantasm Armityle." Right at the start of this shot, a minor animation error occurs where part of his hair suddenly becomes more shadowed partway into the shot. (00:14:25)
Unleash the Dragon: Part 2 - S3-E26
Other mistake: When Chaos Neos destroys Uria, Marcel takes 2500 points of damage. However, Marcel should have lost 3500 points, because an ability Chaos Neos has is that monster effects are negated, and Uria's attack points were only 1000 because an ability it has is that it gains 1000 attack points for every continuous trap card in the owner's graveyard, meaning its attack points would've been 0. Since Chaos Neos' attack points at that time were 3500, there should've been 3500 points worth of damage. (00:13:05)
Unleash the Dragon: Part 2 - S3-E26
Continuity mistake: When Jaden draws Fifth Hope from his card, his thumb is in a position where it covers part of the artwork. But in a close-up of the card, his thumb has moved further down, and only covers the bottom part of the card. (00:11:45)
Unleash the Dragon: Part 1 - S3-E25
Continuity mistake: When Jaden raises his Instant Fusion card, the card is held at a slanted angle, but in the next shot, the card is held at an upright angle. (00:15:55)
Unleash the Dragon: Part 1 - S3-E25
Continuity mistake: After finally obtaining the Rainbow Dragon, Jesse raises his hand into the air and says "I finally completed the Crystal Beast deck" and Axel replies "You all done talking to this guy over there." At the end of the shot, Jesse's right hand is still raised, but in the next shot of Jesse, his hand is suddenly lowered. (00:13:20)
Unleash the Dragon: Part 1 - S3-E25
Continuity mistake: When Jesse and Axel find the capsule, the rocket it crash-landed is broken into two halves. The front section of the rocket is dark grey, and orange around the area that is broken off. But in the next shot, the front section of the rocket is light grey (also the same colour as the rear section). (00:11:39)
Unleash the Dragon: Part 1 - S3-E25
Other mistake: After Bastion tells Jaden to get to Marcel while they are cornered by the Duel Ghouls, Hassleberry is shown running and says "I summon Black Tyranno", before said monster appears. However, Polymerization is the card that is shown in his hand and not Black Tyranno. (00:07:38)
Continuity mistake: When the Ghouls are breaking into the tennis court, Alexis says "Our only way out is through them" and she and Jim activate their duel disks. When this happens, Bastion and Blair can be seen in the background, with Blair slightly ahead of Bastion. When the shot cuts, Blair is slightly behind Bastion. (00:17:09)
Revealing mistake: When Pegasus has finished designing the Rainbow Dragon card, Chancellor Shepherd and a group of background extras start applauding. There is one extra wearing a lab coat standing behind Shepherd with black hair, who is reused in the same shot when it pans over to another group of extras on the opposite side of the site. (00:03:20)
Breaking of the Sacred Seal - S3-E23
Continuity mistake: When they have finished setting up the inter-dimensional duelling system, there is an overview shot that passes over the main characters. In this shot, Pharaoh can be seen sitting on a console, directly in front of Blair. When the shot cuts to Blair and Pharaoh, Pharaoh is now sitting in front of Blair, to her right. (00:19:30)
Breaking of the Sacred Seal - S3-E23
Character mistake: When Marcel activates his two face-down cards, he says "I'll start by revealing my two face-down cards which both happen to be Break the Seal spell cards", but they are trap cards as they are pink and spell cards are green. (00:15:10)
Breaking of the Sacred Seal - S3-E23
Continuity mistake: When Echo is warning Pegasus not to move closer, in an overview shot, there are two aides on his left. One is a few meters next to him, and the other is a few more meters ahead of the first aid. Just under a minute later, when Pegasus says "Okay, I was kind of with you until that last bit", both aides to the left of Pegasus are side-by-side. (00:10:55 - 00:11:50)
