Both the character's name as the Pokémon are customizable. Ours can choose to start the game, and the Pokémon can be changed in the game menu. The names are unique, and if you have a common name, this is already taken. So, how much more quickly you know, before you can choose. Those who have caught and Ash, Misty, Allegra, Oak, or Jessie and James are in luck.
