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 Hassleberry and the two Slifer Red students are sitting outside the classroom, there are two piles of books around them. A couple seconds later, when Hassleberry and one of the Slifer Red students stand up after Crowler appears, the books are now in three piles. (00:06:11)
Other mistake: After Cyber End Dragon has been summoned and its attack points have doubled, the next shot of Zane shows Chimeratech Overdragon on his duel disk, instead of Cyber End Dragon. (00:16:10)
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
Continuity mistake: When Alexis first appears and watches the duel between Jasmine, Mindy and the MaƮtre 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)
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)
Mirror, Mirror: Part 1 - S2-E26
Continuity mistake: When Jaden, Aster and Bastion run up to the simulation building at Kaibaland, once they stop running, Jaden and Aster's forearms are raised. In the next shot, their arms are suddenly lowered. (00:02:04)
Continuity mistake: After the duel, Chazz looks at his deck and the three Ojama cards can be seen at the bottom. Beneath the Ojama cards, the spell card Mystical Space Typhoon can be seen as the next card in his deck, and no other cards are shown. Two shots after, there is a closer shot of the cards, and Polymerization can be seen beneath Mystical Space Typhoon even though it wasn't visible in the earlier shot. (00:19:20)
Other mistake: After Hassleberry activates Survival Instinct and removes from play two dinosaur monsters, the attack points of Curry Fiend Roo go up by 600. However, on the point display that is shown when the points go up, the word DEF can be seen, indicating that it is in defence mode. Since it is the attack points of this card that are going up, and it is currently in attack mode, the word ATK should have been shown in the point display instead. (00:16:18)
Other mistake: Just after Syrus has summoned Ambulance Rescueroid to the field, he uses the effect of Cyber Summon Blaster to inflict 300 points of damage to Hassleberry. At this point, Hassleberry should have 2900 life points (which then go down to 2600). But for a split-second, his life point count reads 4000, which then shifts to 2900 when his life points go down. (00:12:55)
Continuity mistake: When Syrus arrives in the duelling arena and sits next to Hassleberry and Bastion, two Slifer Red students can be seen sitting behind Chazz. A couple minutes later, after Atticus says he and Alexis are going to conquer the world, it cuts to Hassleberry saying "Man, bro bro's got some issues", and the two Slifer Red students behind Chazz have disappeared. (00:05:58 - 00:08:53)
A New Breed of Hero: Part 2 - S2-E7
Other mistake: Aster uses the effect of Magical Stone Excavation to send two cards to the graveyard to bring back one spell card. Polymerization is coming out of his graveyard, but a second later, it is now Misfortune that returned from the graveyard. (00:14:10)
Continuity mistake: Chazz and Hassleberry argue about the Slifer Red meals, and then Chazz grabs onto Hassleberry's hand when he tries to pour soy sauce in his bowl. While this happens, Syrus is holding a bowl low to the table and is holding chopsticks pointed forwards. When the shot cuts to Syrus, the bowl is lifted higher off the table and the chopsticks are pointed downwards. (00:00:48)
Continuity mistake: When the crashed satellite is first shown, there is rubble shown next to the satellite and the Kaiba Co Ltd can be seen on the satellite, positioned to the opposite end of the rubble. A couple seconds later, when the lid to the card capsule falls off, the logo is now positioned on a different side of the satellite, closer to the rubble. (00:09:28)
A New Breed of Hero: Part 1 - S2-E6
Continuity mistake: When Aster tosses the cards over the card thief, an Elemental Hero Wildheart card lands on his chest face up and another card lands on his chest face down. Seconds later, when Syrus and Bastion go to check on him, the Wildheart card is now on the ground and there are three face down cards on his chest. (00:06:31)
Continuity mistake: When Chazz is standing on the Slifer Red dorm roof and says Jaden didn't see the Society of Light, Syrus and Hassleberry can be seen standing on the ground at rotated angles. When the shot cuts to them, they appear to be side by side, and not rotated at all. (00:01:15)
Continuity mistake: When Jaden runs over to the crashed satellite, there is a close-up of the Kaiba Co Ltd logo that is covered in dirt. In the next shot, the dirt has disappeared from the logo. (00:09:34)
Revealing mistake: While Syrus and Hassleberry are calling for Jaden, there is a shot of a cliffside, that then pans upward to reveal the back side of the Slifer Red dorm. The windows on the left side of the dorm appear to have been drawn wrong, as they are smaller than the windows on the right side, even though they are all supposed to be the same size. (00:00:03)
Mirror, Mirror: Part 1 - S2-E26
Continuity mistake: When Sarina is asking Aster why he thought Sartorius was the one who took him in all those years, Syrus and Hassleberry are standing in front of Jaden and Aster. Seconds later, when Sarina says they must face her in a duel, Syrus and Hassleberry have disappeared from in front of Jaden and Syrus. (00:04:50)
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)
