Here's why:
* Shayman isn't in the game: Shayman is a Pokémon introduced in later generations, not in Pokémon Ranger: Shadows of Almia.
* No specific missions: Pokémon Ranger doesn't have specific "missions" for individual Pokémon. The game focuses on capturing Pokémon to help solve problems and protect the region.
However, you can encounter Shayman in Pokémon Ranger: Shadows of Almia:
* Using cheats: If you use cheat codes or save editing tools, you can potentially add Shayman to your game. This is not officially supported by the game developers and may cause issues.
* Fan-made modifications: There may be fan-made modifications or ROM hacks that add Shayman to the game, but these are not officially sanctioned by Nintendo and are not considered legitimate gameplay.
Important Note: Using cheat codes or modifications can potentially corrupt your game data or lead to other issues. It's generally best to play games within their intended rules and enjoy the experience as it was designed.
