I do wonder if Megas will even be a thing this generation, but the new female trainer is very adorable. Likely not expecting a BW-esque Pokedex again since it appears the protagonist's mother has a pet Meowth, but we can only imagine.
Popplio getting hated so much reminded me exactly of Oshawott once being that way when the Unova starters were first revealed. Now I feel Oshawott became most popular thanks to the evolutions, whereas the initially popular one (Snivy) got a bit divided over.
