Other mistake: Franz gives up 1000 life points to destroy all monsters on Jaden's field, going from 2200 to 1200. Later, Franz activates Winged Dragon of Ra's secret ability, allowing him to sacrifice all but 1 life point to add it to Ra. However, when this happens, his life point count starts at 4000, when it was 1200 earlier. Ra gains 1199 attack points, so it does gain the correct number of points, but it was still wrong for the life point count to read 4000. (00:12:45 - 00:14:30)
Plot hole: Jaden activates Miracle Fusion, allowing him to fuse the Elemental Heroes Flame Wingman and Sparkman in his graveyard to summon Shining Flare Wingman. However, Flame Wingman was never sent to Jaden's graveyard. He activated De-Fusion (allowing him to summon Avian and Burstinatrix) when it was about to be destroyed, which meant Flame Wingman was sent back to his deck and not his graveyard. (00:17:13)
Blinded by the Light: Part 1 - S2-E35
Continuity mistake: When Aster shows Jaden and Hassleberry the medals he won, some of the medals can be seen in between each of his fingers. Two shots later, when Aster says "I guess I've done all right", there are two fingers where medals cannot be seen in between. (00:06:53)
Blinded by the Light: Part 1 - S2-E35
Continuity mistake: The night before the duel, Jaden is in his dorm, sitting at his desk and looking at his cards. In an overview angle, he has his right hand over some cards, but in the next shot, he is suddenly holding two cards in his hand. (00:09:57)
Blinded by the Light: Part 1 - S2-E35
Continuity mistake: When Jaden is looking at his cards the night before the duel, he has the cards on a mat. The cards are near the front of the mat, but a couple of shots later, the cards are nearer to the back of the mat. (00:09:58)
Blinded by the Light: Part 1 - S2-E35
Continuity mistake: When Jaden finds the Ojama cards whilst they are being held by two crabs, he places his fingers on the Ojama Yellow card. At first, his fingers are placed toward the middle of the card, but when the shot cuts, his fingers are toward the left hand side of the card. (00:11:05)
Blinded by the Light: Part 1 - S2-E35
Continuity mistake: When Professor Banner says he doesn't know whether it's worse to live in the well or to live with Chazz, the three Ojama cards are being held by two crabs. There is a small gap between the three cards, but in the next shot, the cards are closer together. (00:11:22)
Blinded by the Light: Part 1 - S2-E35
Continuity mistake: After Professor Banner goes back into the cat's body, there is an overview angle where the Ojama cards are on Jaden's desk. Two of the cards are positioned at rotated angles, but a couple of shots later, the cards are not rotated. (00:11:50)
Blinded by the Light: Part 1 - S2-E35
Continuity mistake: When Jaden and Chazz are about to duel, Jaden raises his deck and speaks to the Ojamas briefly. In this shot, his left thumb is placed against the corner of the cards. In the next shot, his left thumb is away from the corner. (00:13:37)
Pro-Dueling - S2-E38
Other mistake: When Crowler and Bonaparte approach Damon and Mathmatica during their duel, Mathmatica appears to have 4000 life points. A couple minutes later, when Mathmatica loses 1000 life points due to Damon correctly guessing which card he would draw, Mathmatica's life points are now 3000 (which then go down to 2000). (00:04:33 - 00:06:53)
Pro-Dueling - S2-E38
Other mistake: When Damon summons Doron to Mathmatica's side of the field due to Mathmatica activating Illegal Summon, the monster is summoned in defence mode, but the display reads ATK, indicating that it is in attack mode. (00:05:18)
Pro-Dueling - S2-E38
Other mistake: When the Maître D increases the attack points of his Bacchus monster, the Life Point display is shown to display the attack point count going from 1600 to 1900, and not the Attack Point display that is usually shown. (00:11:09)
Pro-Dueling - S2-E38
Continuity mistake: When Alexis first appears and watches the duel between Jasmine, Mindy and the Maître D, her duel disk on her right arm. A couple seconds later, when she approaches them, the duel disk is on her left arm. (00:11:50 - 00:12:18)
Pro-Dueling - S2-E38
Other mistake: When Alexis activates her Ritual Weapon spell, her Cyber Angel Benten gains 1500 attack points. When this happens, the Life Point display is shown to display the Benten's attack points going from 1800 to 3300, instead of the Attack Point display that should've been shown. (00:13:40)
Don't Fear the Reaper - S2-E39
Continuity mistake: When Chazz throws Jaden the Grim Reaper card, once he catches it, he has his middle finger placed along the side. In a close-up of the card, his finger cannot be seen along the side of it. (00:01:54)
Don't Fear the Reaper - S2-E39
Continuity mistake: When Jaden hands Lucien his duel disk, Lucien takes back the duel disk and holds it. Two shots later, Lucien is still holding the duel disk, but when the shot cuts, it is suddenly lowered. (00:03:23)
Don't Fear the Reaper - S2-E39
Revealing mistake: After Jaden summons Dandelion in defence mode, he places a card face down. When he goes to insert the card into the slot on his duel disk, his hand doesn't appear to align with the duel disk. His hand appears to pass over the spherical red light on the duel disk, and not the card slot. (00:13:02)
Don't Fear the Reaper - S2-E39
Continuity mistake: When Lucien activates his Slash Draw for the second time, he has his right hand placed over the front of the duel disk after inserting his card into the slot. In the next shot, his right hand is at his side. (00:15:15)
Continuity mistake: When Chazz appears on the staircase in front of Jaden, Syrus, Hassleberry and Atticus, he puts his hands on his hips. When it cuts to a closer shot of Chazz, his hands are at his side. (00:08:55)
Continuity mistake: After Chazz hands Jaden the card to use in the duel, in the shot of Jaden saying "Uh, okay", the card is level with his face. In the next shot, the card is lowered away from his face. (00:10:52)
