The Origin of the Fantastic Four: Part 1 - S1-E1
Other mistake: When Puppet Master is making a clay figurine of Thing, the mold he uses doesn't have a Thing-shaped interior with which to make a detailed figurine. The figurine should have just looked like an undefined human-shaped figure. (00:15:20)
Injustice For All (2) - S1-E19
Other mistake: Unless he escaped prison, it makes no sense for Copperhead to be in the police van with the other Secret Society members. You can see him sitting there across from Solomon Grundy and The Shade.
Other mistake: Kendra slaps the right side of Donna's face to stop her from freaking out. Donna then rubs the left side of the her face. (00:14:05)
Other mistake: In the English dub of the series, Tai's last name is Kamiya; however, when he makes reference to the family name plate his father put on the front door in this episode, the name displayed is Yagami. (00:03:00)
Other mistake: In the scene where Raphael and Michelangelo report from their ceiling vantage point, we see a hallway full of Foot ninjas. Strangely, we can see a brief shot of an Earth Protection Force trooper walking peacefully among amongst the Foot even though they are hostile to them. (00:07:50)
Is Lupin Burning... ?! - S1-E1
Other mistake: The logo of the evil organization, Scorpion, contains just a little misspelling. It's missing the R. (00:02:50)
Other mistake: At Honker Burger, when Skeeter introduces Doug to Patti, the lower half of Doug's body and both of his arms are missing; the animation is incomplete. (00:20:55)
Blue Wants to Play a Game - S1-E12
Other mistake: The jigsaw puzzle Steve and Blue help Shovel and Pail with has a picture of everyone playing musical chairs from the Mailbox's Birthday episode, but Steve suddenly isn't in the puzzle. He played musical chairs, so he should've been in the puzzle.
Tag Team Trial: Part 2 - S1-E11
Other mistake: Syrus summons to the field Drillroid and has it attack the Gate Guardian in defense mode, but is blocked by Defence Wall because of its effect, and Defense Wall is destroyed. Because of this, Jaden and Syrus lose 500 Life Points. While it does seem logical that their life points would go down because Drillroid has 1600 attack points and Defense Wall has 2100 defense points, they should not lose life points in the first place. This is mainly due to the fact that Drillroid's effect causes a defense position monster to be destroyed instantly, without losing life points. If Drillroid was capable of destroying Defence Wall, then their life points should have remained at 1700. (00:08:00)
Other mistake: In the scene where Yakko, Wakko and Dot are sitting at their desks repeating Miss Flamiel's every word, Wakko is drawn without legs (only feet) during one shot.
Other mistake: At the end of the intro, before the logo appears you can see Mojo Jojo's brain. His brain is green and it should be pink.
Monkey Fun - S2-E13
Other mistake: Season 2 episode 13 "Monkey Fun": Just before the enlarged Titano appears at the zoo, there is a family watching normal-sized monkeys in a cage. The family father (farthest on the right) has a drawing disorder with his eyes: their pupils look up and down, respectively, giving him a rather goofy expression.
Kiss 'N Tell - S1-E4
Other mistake: The door that Link blasts down to get into Ganon’s bed chamber has a locking bar on the front of it. A bar like that is used to slide across when a door is two doors to keep them sealed together closed. But when Link blasts it open, it is very obvious this is just a single door with a board on the front that doesn't even stretch to the ends of the door. This makes the locking board and support bones on it completely pointless. (00:12:20)
Vampire Bats and Scaredy Cats - S2-E2
Other mistake: When the Mystery Company find a torn paper in a coffin, it is written exo-6 and something else. They find later that exo is the first part of exotic. The way the paper was torn, you should be able to see the lower part of the missing letters.
To Touch a Hummingbird - S2-E10
Other mistake: Chris gets on the zip line and hooks up. Martin just stands behind him, not hooked up to the zip line. Chris zooms off down the line chasing the hummingbird. A few seconds later, Martin is suddenly on the zip line also and right behind Chris.
Coffee Quest/Phoenix Rises - S1-E18
Other mistake: In Phoenix Rises, when Phoenix runs away, the Big Coffee sign is missing.
What If... Captain Carter Were the First Avenger? - S1-E1
Other mistake: The premise of the first episode is flawed; "a single choice" should make the difference, the choice being identified as Ms. Carter not leaving the room to get in the observation booth. But in the normal timeline the booth is exactly where all the other characters were. In this reality everyone else is downstairs, with the German spy that inexplicably sets the bomb early. If anything, it's his bizarre, suicidal choice that matters.
Suggested correction: Except it was her decision to not leave the room that delayed the procedure and gave Heinz Kruger the chance to attack. And with her in the room, she is now given the chance to volunteer to take the serum.
How did her staying delay the procedure? Besides, in OTL the spy only triggered the bomb after he saw the procedure succeed, to know it works before stealing it.
Other mistake: When Viper slides the swords to Jackie and they come to a rest next to him, there is a small paper spider right beside Jackie. The only paper spider in the room, however, is Origami himself, and he is actually too far away at that moment and too big to fit the bill. Guess some of the animators got their depth perception messed up.
Crimes R Us - S1-E19
Other mistake: When the Mario Bros. are suspicious of Clyde, the background is the treasury instead of the dungeon. (00:10:25)
Until Sunset, the Full Moon - S1-E7
Other mistake: In Italy, in a mountain home in the Alps, owned by Italians, Zenigata is using a big bottle of sake to cook. Not exactly what you find in 99.9% of Italian kitchens. (00:07:30)
