Monster from the Go Era

The concept of this story is interesting but it's too rushed it goes from 0 to 100 and even though the gimmick he got isn't necessarily OP he can use a fully evolved Pokémon and who knows what amount of power from the start it's too much , at first I thought the MC was going to be able to use all his Pokémon from Pokémon go but they would all be in their first evolutionary stage and with the same power they had when they were first caught in the game and the MC to avoid awkward questions would only use Pokémon he could catch in Kanto in other words he wouldn't come out with that he caught a chimchar or another Pokémon from a different region.
