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)
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)
Other mistake: When Zane has Cyber End Dragon attack Elemental Hero Shining Phoenix Enforcer, Aster activates a trap card that allows him to send 5 monsters to the graveyard. One of these monsters is Elemental Hero Clayman, but it's shaded orange, and since Clayman is not an effect monster, it should be shaded yellow. (00:18:55)
Continuity mistake: After Hassleberry has Dark Tyrano attack The Magician and Sartorius' life points go down to 3600, when he starts saying "Maybe you should spend less time talking...", his right fist is raised slightly. In the next shot, his right fist is suddenly raised further. (00:09:12)
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)
Tough Love - S2-E43
Character mistake: When Zane is explaining Cyberdark Dragon's ability to Syrus, he says that for every card in his graveyard, his dragon gains 100 points, before saying "Since there are 38 dragons in my graveyard, Cyberdark Dragon gains 3800 points." However, his deck consists of monster cards, spell cards and trap cards, his statement that there are 38 dragons in his graveyard is incorrect. (00:18:00)
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 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)
Other mistake: When Jaden destroys Slifer 30, Bob tells him he has to drink a full bowl of water in 60 seconds. Once he finishes the bowl, water is shown dripping from his head and splashing up from the bowl, meaning that the bowl couldn't have been empty. (00:14:14)
Character mistake: When Jaden uses the spell card Gift of the Martyr to increase Neos' attack points to 5400, T-Bone shouts "That ain't right. Fifty-four grand?", but fifty-four grand would be 54,000 and not 5400. (00:17:52)
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: 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 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)
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)
A New Breed of Hero: Part 1 - S2-E6
Other mistake: After Jaden activates Miracle Fusion, he removes Elemental Heroes Flame Wingman and Sparkman from his graveyard (and removes them from play) so that he can summon Shining Flare Wingman. In the shot of the cards coming out of the duel disk, Sparkman is shaded orange. But since Sparkman is not an effect monster, it should be shaded yellow. (00:14:50)
A New Breed of Hero: Part 1 - S2-E6
Other mistake: When Jaden has Elemental Hero Flame Wingman attack Aster's Elemental Hero Clayman, the Clayman card appears to be orange. However, monster cards are only orange when they have a special ability, and since Clayman doesn't have an ability, it should be yellow. (00:10:54)
Other mistake: When Zane activates Trap Jammer, the monster Elemental Hero Bubbleman can be seen on his duel disk, even though Cyber Dragon is the only monster on his field and Zane does not have Bubbleman in his deck. (00:09:57)
A Hassleberry Hounding - S2-E3
Character mistake: At the start of the episode, Jaden says that he and Syrus have to carry 14 replacement duel disks across campus, which is later revealed to be because Hassleberry beat each of the 14 students in a duel and then stole their duel disk. But during the duel later on, Hassleberry says "I'm beating you the same way I beat my last 12 rivals", instead of the 14 students that were stated earlier. (00:00:09 - 00:15:35)
Champion or Chazz-Been? - S2-E2
Revealing mistake: After Bonaparte has introduced Reginald, it cuts to Jaden, Syrus, Alexis and Crowler sitting in the seating area. On the third row are two Slifer Red students. The first is looking at his cards, while the second is looking at the first student's cards as well. Later on, when Reginald has Gilford the Legend attack Chazz, it cuts to Jaden saying "Here we go", and those two students are in the exact same position, looking at the cards. Clearly the same animation was reused on both occasions. (00:03:58 - 00:11:03)
