| Pokémon | Move | Game | Notes | Picture |
Lance's Dragonite | Barrier | Pokémon Red, Green, and Blue
Pokémon Red and Blue | Dragonite cannot know Barrier until Generation VI, in which a Dragonite based on Lance's that knows Barrier was distributed. |  |
Lance's Aerodactyl | Rock Slide | Pokémon Gold, Silver, and Crystal | Aerodactyl could not learn Rock Slide until Generation III. |  |
Cool Couple Carl & Nia's Muk
(Trainer Tower) | Shadow Ball | Pokémon FireRed and LeafGreen (Japanese) | In the Japanese version of Pokémon FireRed and LeafGreen only, the layout of Trainer Tower can be customized by scanning e-Reader cards. The Pokemon used by each trainer are partly determined by the order in which the e-Cards are scanned. If Cool Couple Carl & Nia appear on the first or seventh floor of Trainer Tower, they will use a Muk which knows Shadow Ball, a move it cannot learn until Generation IV. It was likely intended to be Shadow Punch, a move Muk can learn. |  |
Cooltrainer Dianne's Lanturn
(Victory Road) | Earthquake | Pokémon Emerald | |  |
Gentleman ピエール's Mawile
(Trainer Hill 4F) | Comet Punch | Pokémon Emerald (Japanese) | In the Japanese version of Pokémon Emerald only, the layout of Trainer Hill can be customized by scanning e-Reader cards. This Trainer and their Mawile will appear if and only if exactly seven such cards have been scanned, regardless of which cards they are, so that an eighth default Trainer needs to be added to fill out the roster with two Trainers per floor. | |
Battle Hall Totodile | Brine | Pokémon Platinum, Pokémon HeartGold and SoulSilver | |  |
Battle Hall Roselia | Sludge | Pokémon Platinum, Pokémon HeartGold and SoulSilver | It was likely intended to be Sludge Bomb, a move which Roselia can know. |  |
Battle Hall Anorith | Stone Edge | Pokémon Platinum, Pokémon HeartGold and SoulSilver | Anorith's evolution, Armaldo, can learn Stone Edge. |  |
Ace Trainer Nick's Squirtle (Union Cave B2F) | Curse | Pokémon HeartGold and SoulSilver | Squirtle can only learn Curse in Generation II; however, Pokémon from Generation II games cannot be transferred to Generation IV. This error is likely due to Nick's Squirtle retaining its moveset from Pokémon Gold and Silver, in which it could learn Curse. | |
School Kid Ann's Sandy Cloak Wormadam
(Route 12) | Leaf Storm | Pokémon Black and White | Only Plant Cloak Wormadam can learn Leaf Storm. Due to learning the move at the same level, this Wormadam should instead know Fissure. |  |
En's Moltres (PWT) | Leer | Pokémon Black 2 and White 2 | Moltres could only learn Leer in Generation I, and starting in Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!, neither of which can be transferred to Generation V. |  |
Abel's Metagross | Ice Beam | Pokémon Black 2 and White 2 | From November 18 to 20, 2012, Metagross knew Ice Beam. After that, it was replaced with the correct move, Ice Punch. This has been officially confirmed as an error, due to being based on a real-world Trainer. |  |
Totem Wishiwashi's Ally Alomomola
(Brooklet Hill) | Water Gun | Pokémon Sun and Moon | The Totem Wishiwashi can summon an ally Alomomola which knows Water Gun. | |
Battle Royal Shuckle | Stockpile | Pokémon Sun and Moon (v1.0) | Starting in v1.1, this Shuckle instead knows Double Team. | |
Battle Tree Kommo-o | Shell Smash | Pokémon Sun and Moon (v1.0) | Starting in v1.1, this Kommo-o instead knows Draco Meteor. | |
Battle Tree Rotom | Blizzard | Pokémon Sun and Moon | In USUM, this Rotom's form is corrected to Frost. | |
Battle Tree Rotom | Air Slash | Pokémon Sun and Moon | In USUM, this Rotom's form is corrected to Fan. | |
Hiker Jim's Onix
(Underground Path (Kanto Routes 7–8)) | Wrap | Pokémon: Let's Go, Pikachu! and Let's Go, Eevee! | It was likely intended to be Bind, a move which Onix can know. | |
 
1★ Wild Area News
Drilbur → Excadrill | Hydro Pump
(Max Geyser when Dynamaxed) | Pokémon Shield
(Available directly) Pokémon Sword
(Available if raid was hosted from a player with Shield) | For a portion of the first day of this round of the Wild Area News for April 28 to May 11, 2020, 1★ Drilbur raids originating from Shield came with the illegal move Hydro Pump. The same raids for the rest of the event's duration, or from Sword, came with the correct move, Scratch. Players who caught a Drilbur with Hydro Pump cannot trade or battle online with it unless that move is forgotten; after doing so, it cannot be relearned. These erroneous Drilbur otherwise function like other Drilbur, and can evolve into Excadrill with Hydro Pump. Additionally, while Dynamaxed, these Drilbur and Excadrill also have access to Max Geyser, which is typically unobtainable as neither can legitimately learn any Water-type attacks. |

Pokémon GO Alolan Sandshrew → Alolan Sandslash | Poison Sting and/or Sand Attack | Pokémon HOME
(After transferring from Pokémon GO) Pokémon Sword and Shield
(Can be imported to Pokémon Sword and Shield) | Alolan Sandshrew and Sandslash transferred from Pokémon GO to Pokémon HOME from November 11 to November 16, 2020, erroneously use the level-up learnset of their Kantonian counterparts from Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!. Alolan Sandshrew and Sandslash in Pokémon HOME, Sword, or Shield with illegal moves had their moves replaced with moves from their level-up movepool on November 16, 2020, opening Pokémon HOME at any point between that date, and the release of HOME v3.0.0 would cause HOME to search all Sword and Shield savefiles on the console and correct the illegal movesets. Players who transferred an Alolan Sandshrew and Sandslash with any of these illegal moves cannot trade or battle online with it unless that move is deleted. These erroneous Alolan Sandshrew and Sandslash otherwise function like other Alolan Sandshrew and Sandslash. | |
 
Pokémon GO Alolan Vulpix → Alolan Ninetales | Ember, Will-O-Wisp, Fire Spin, Flamethrower, and/or Fire Blast
(Max Flare when Dynamaxed) | Pokémon HOME

Players who transferred an Alolan Vulpix or Ninetales with any of these illegal moves cannot trade or battle online with it unless that move is deleted. These erroneous Alolan Vulpix and Ninetales otherwise function like other Alolan Vulpix and Ninetales, with Alolan Vulpix from GO being able to evolve into an Alolan Ninetales with level-up moves that are otherwise only in Kantonian Vulpix's movepool, such as Flamethrower and Fire Blast. Additionally, while Dynamaxed, these Alolan Vulpix and Alolan Ninetales also have access to Max Flare, which is typically unobtainable as neither can legitimately learn any Fire-type attacks. However, both Alolan Vulpix and Alolan Ninetales can use Max Flare by using Weather Ball powered up into a Max Move if it is sunny, though this is considered an extension of Max Strike. | |
 
Pokémon GO Galarian Meowth → Perrserker | Feint | Pokémon HOME

(After transferring from Pokémon GO) | Alolan Geodude, Graveler and Golem transferred from Pokémon GO to Pokémon HOME from November 11 to November 16, 2020, erroneously use the level-up learnset of their Kantonian counterparts from Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!. Due to being unable to be transferred out of Pokémon HOME, all Alolan Geodude, Graveler or Golem deposited in Pokémon HOME that had any illegal moves had their moves replaced with moves they can learn in their level-up movepool on November 16, 2020. | |

Players who transferred a Galarian Ponyta and Rapidash with any of these illegal moves cannot trade or battle online with it unless that move is deleted. These erroneous Galarian Ponyta and Rapidash otherwise function like other Galarian Ponyta and Rapidash. Galarian Rapidash can only learn Flare Blitz after having been powered up fully and reaching the Best Buddy Buddy Level in Pokémon GO as a Galarian Ponyta prior to being transferred to Pokémon HOME, then evolving into Galarian Rapidash in Pokémon Sword and Shield. | |

Psychic Corbin's Banette
(Route 228) | Shadow Force | Pokémon Brilliant Diamond and Shining Pearl | It was likely intended to be Phantom Force, a move which Banette can know. |  |
Dawn's Mr. Mime | Power Whip | Pokémon Brilliant Diamond and Shining Pearl | Second battle with Dawn (only used if the player picked Chimchar as their first partner Pokémon). It was likely intended to be Power Swap, which Mr. Mime can know. | |
