Manga move errors
In the Pokémon manga, a situation will sometimes occur where a Pokémon knows a move it cannot learn legally in any of the games. It is unknown whether these are actual mistakes, a writing policy of not having to stick to the games too closely, or merely the Pokémon using an attribute that shares the name of a move in the games.
Occasionally, in-game event Pokémon that can be transferred onto the main series games have a move that is not normally included in that Pokémon's moveset (a prime example being Pokémon Box Ruby & Sapphire, which gave away four separate Pokémon with moves that were not normally available to that specific Pokémon).

How I Became a Pokémon Card
Pokémon in How I Became a Pokémon Card will often use moves that they cannot learn in the games. These are generally not errors, though, because this series is based on the Pokémon TCG; the "illegal" moves Pokémon use in this series are moves from their TCG cards.
