>>55464876Pokemon can change their personality when they evolve, that's a fact. Besides, Charizard, with or without Ash, is still self-sufficient because he always trains. He's charismatic, funny, can play with Bulbasaur and Squirtle and in the next chapter have a really good battle.
Infernape recycles Charizard's arc, his entire existence revolves around that, it's only there to fight and it's very one-dimensional, that's why in Journeys he went unnoticed. He is a single-use pokemon. DP is overrated af.
