From Bulbapedia, the community-driven Pokémon encyclopedia.

In the Pokémon anime, there will often come up a Pokémon that knows a move it cannot learn legally in any of the games. It is unknown whether these are actual mistakes or a writing policy of not having to stick to the games too closely.

Less blatant examples

• During Caterpie's battle with Pidgeotto in EP003, Ash tells Caterpie to use Counter; however, Caterpie cannot learn Counter and does not know how to use it, so it panics and braces for impact.
• In EP050, Misty gets stuck with Psyduck in her battle with Ash. Ash doesn't battle seriously and has Bulbasaur simply lick Psyduck's head and tickle it with its vines. This is not to be confused with the actual moves Lick and Tickle, the latter of which was later introduced in Generation III. Bulbasaur still cannot learn Lick or Tickle.
• In DP028, some Drifloon were used to fly around the area. However, they did not use the actual move Fly. The Pokédex specifically states that Driftloon can't carry the weight of children anyway.
• A group of Combee in DP032 appear to be using Psybeam, however, this is actually the anime representation of Vespiquen's Attack Order.
• DP071 and DP072 feature a Riolu that can use Aura Sphere. This is due to its unique ability to manipulate aura prior to evolution. This episode is directly based on a mission from Pokémon Ranger Batonnage featuring a similar Riolu. This is the only way a Riolu that knows Aura Sphere is available in the games.
