- Ash would have caught many more Pokémon
- Team Rocket would be more terrorist-y
- Jessie, James and Meowth would be more successful
- I don't care how much time and money it would take, the battles would be more detailed like they are at the start of most of the movies, none of this still Pokémon on moving background business
And most importantly:
The original dub actors would still be running the show. I caught the first episode of Battle Frontier and couldn't even finish it. It was like nails on a chalkboard.
