Charizard

Charizard was James' starter Pokémon in Pokémon LeafGreen. As such, she was the first Pokémon to join James' team.

History
James chose to use Charizard in LeafGreen because his favorite of the Kanto starters is Charmander and he has used the species the most when doing repeat playthroughs. Charizard also happened to fit better when the rest of the team was being planned out ahead of the series.
