I knew that Ash had already Gigantamaxed Pikachu and Gengar for the first time, he also Mega Evolved Lucario for the first time, and he transformed Greninja into Ash-Greninja for the first time until I thought that Greninja had permanently lost this transformation after Ash released him. Other than Pikachu, Gengar, Lucario and Greninja, I’m just wanting to know why you think that the writers permanently refused to let Ash Mega Evolve or Gigantamax Pokémon capable of their Mega Evolutions and Gigantamaxes for the first time?
