Unleash the Dragon: Part 2 - S3-E26
Other mistake: When Jesse activates the spell card Prism Wall, just as he explains that "So Yubel and I, we both take damage", Elemental Hero Bubbleman can be seen on his duel disk, even though Jesse does not have this card in his deck. (00:18:30)
Unleash the Dragon: Part 2 - S3-E26
Continuity mistake: When Marcel activates Immortal Class, his left arm is extended as the face-down card rises. In the next shot, his left arm is suddenly bent so that he can use the duel disk. (00:13:48)
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)
