Here's why:
* Story Focus: The story of Pokemon Mystery Dungeon revolves around your chosen starter and their journey to understand themselves and their place in the world. The focus is on the journey and character development, not on becoming the strongest.
* Unique Abilities: The starter Pokemon in each game have unique abilities that are central to the story and gameplay. Evolving them would change their core abilities and potentially disrupt the narrative.
* Balanced Gameplay: Having starter Pokemon stay at their initial forms keeps the game's difficulty and balance intact. If they evolved, they could become overpowered compared to other Pokemon encountered throughout the game.
Instead of evolving your starter, you can:
* Level Up: Your starter will still gain experience and become stronger, even without evolving.
* Learn New Moves: As your starter levels up, it will learn new moves that can enhance its abilities and make it more versatile in battles.
* Gain New Abilities: Your starter will gain unique abilities as you progress through the story and complete missions.
* Focus on Other Team Members: You can build a team of other Pokemon to complement your starter's strengths and weaknesses.
While you can't evolve your starter in Pokemon Mystery Dungeon, the games still offer an exciting and engaging experience with plenty of opportunities for growth and adventure.
