Other mistake: During the Pokérap, when the Poliwrath name is said, the Pokémon shown is actually Poliwag. Also, when the Graveler name is said, the Pokémon shown is actually Geodude.
Other mistake: Larvitar's weight is 158.7lb, but Ash can carry it in his backpack without any problems.
The March of the Exeggutor Squad - S1-E41
Other mistake: The Pokemon Exeggcute is shown evolving in to an Exeggutor naturally. But the Pokemon Exeggcute can only evolve into an Exeggutor with the use of a leaf stone. In the Japanese version, there is a mention that something in these woods causes Exeggcute to evolve without using the Leaf Stone (when Exeggcute evolves, James even mentions that there is no stone). However, as this was skipped in the English version, it creates a plot hole.
Other mistake: Assunta's Ivysaur attacks Sparky too early, before the battle even started, not to mention Assunta haven't given it any commands during the battle.
Mystery at the Lighthouse - S1-E13
Other mistake: When Professor Oak goes to rotate his monitor, his right index finger is intermittently not coloured in. (00:09:15)
Pokemon, I Choose You! - S1-E1
Other mistake: When Pidgey turns its head to see Ash with a Poké Ball, its head feathers beside its eyes are mistakenly coloured cream instead of brown. (00:11:36)
Bulbasaur and the Hidden Village - S1-E10
Other mistake: In the scene when Team Rocket tries to steal the Pokemon, Bulbasaur saves Oddish. Ash comes to help push Bulbasaur, and for a few frames you can see 2 sets of hand prints cut out where Ash's hands go.
Other mistake: When Team Rocket is running away with the trophy, James falls flat on the ground, and an indentation of his body as well as the trophy is made. The indentation shows a perfect match to the trophy, but James' arms were partially covering it, so there shouldn't be a perfect indent of the trophy in the ground. (00:05:18)
What You Seed Is What You Get - S7-E1
Other mistake: When Poliwrath first appears in the Pokémon Trainer's Choice, its swirl mistakenly faces clockwise instead of counterclockwise. (00:12:13)
Abra and the Psychic Showdown - S1-E22
Other mistake: When Ash says, "Without a Marsh Badge, I can't get into the Pokémon League!" the strips on Pikachu are missing. Also, Ash does not have gloves, but in the next shot, he does. (00:07:11)
Mystery at the Lighthouse - S1-E13
Other mistake: When Ash and friends are first seen walking on a path, Pikachu's cheek pouches are missing. (00:01:14)
Other mistake: When the camera pans across the Pikachu when they are surprised, one of them is missing its cheek pouches while another is missing its left one. (00:03:06)
Other mistake: When Ash and friends are first seen when a Ghost Pokémon laughs, the base on Pikachu's tail is missing. (00:07:47)
Other mistake: When Brock says, "Yeah. The season of love is when Butterfree lay their eggs," two Butterfree occasionally are missing feet, and another one occasionally has a part of its wings mistakenly colored black instead of white. (00:01:49)
Clefairy and the Moon Stone - S1-E6
Other mistake: When the camera begins panning back to show Seymour, Ash, Butterfree, Zubat, and Brock, Pikachu's mouth is missing. (00:11:18)
Fushigidane and Fushigidane! Regaining the Monster Balls!! - S7-E34
Other mistake: The English title card misspells Poké Balls as "Pokéballs." (00:02:41)
Other mistake: When Ash, Misty, and Brock are worried about the cyclone approaching, the edges of Meowth's ears are mistakenly colored tan instead of black. (00:20:08)
Flower Power - S3-E6
Other mistake: During the second battle with Team Rocket, James tells Victreebel to use Take Down, but it actually uses Swords Dance. This error is corrected in the Polish dub. (00:18:08)
Other mistake: In the English dub, in the Executive Production section of the credits, TV Tokyo is misspelt as "TV Tokoyo." Additionally, from "Fear Factor Phony" to "Time Warp Heals All Wounds," The Pokémon Company is misspelt as "The Pokemon Company," lacking the accent over the "e." (00:20:46)
Protecting the Egg! The Life Born in a Storm! - S5-E49
Other mistake: When Nurse Joy says she will take Larvitar's temperature one more time, the Pokémon Center is dark despite the power not going out yet. (00:04:32)
