James' One-N-Done Run: Leaf Green is a Pokémon run being attempted by James The Animator.


The One-N-Done Run is a fairly simple run, with only two rules:

  1. You can only catch one Pokémon on each route. You want to catch Meowth on Route 8? Fine, but you can't catch anything else.
  2. You can't catch any Pokémon twice. If you want to, you may outlaw catching Pokémon in the same evolutionary line as well.
