Here's how it works:
1. The Beginning: You start the game by answering questions about your personality. This helps the game determine which Pokémon best suits you.
2. Partner Pokémon: Based on your answers, the game chooses a partner Pokémon for you.
3. Starter Pokémon: You then choose your own starter Pokémon from three options: Charmander, Squirtle, or Bulbasaur.
So, to become Charmander in Pokémon Mystery Dungeon, you don't need to answer any specific questions. You just need to choose Charmander when given the option.
