Kanto
Do I even need to explain Pikachu
Charizard is easily Ash’s strongest Kanto Pokémon (besides Pikachu) and helped him a ton in his early days
Squirtle becomes Blastoise because Blastoise is cooler
Bulbasaur can stay Bulbasaur, it’s probably stronger than a Venusaur
Why the heck didn’t Ash catch that Haunter, I was so mad when I saw that he leaved it behind with Sabrina
Pidegeot is cool, he can stay
Johto
Pikachu because obvious
Cyndaquil would be so much stronger and cooler if he was Typhlosion. Ash needs at least one fully evolved starter
Bayleef is strong and way better than Meganium
Scizor gives Ash vibes
He should’ve had an Espeon. It just has ash written all over it
He should’ve caught that Larvitar and evolved it to a Tyranitar. That’d be sick
