The Endless Variations of a Game-Breaking Pokémon.
Spinda, a normal-type Pokémon from Generation III, has become a nuisance for The Pokémon Company due to its multiple forms, which can have up to four billion possible variations. Spinda's appearance is determined by its individual personality value, making it a centerpiece in its own Pokémon community. However, Spinda has been an issue for Game Freak and The Pokémon Company in terms of transferring the character and all its variants to future games due to compatibility issues with Pokémon Home and Brilliant Diamond and Shining Pearl remakes. As a result, Spinda is the only Pokémon obtainable in Brilliant Diamond and Shining Pearl that can't be transferred to and from these games.
