Steven might be the strongest trainer period in the anime as of now, and even he couldn't do anything against Mega Rayquaza, though he was sort of managing to hold his own against Primals. Alain, who's around Elite 4 level, beat 50% Zygarde pretty easily.
For a legendary as strong as Mewtwo, who was casually creating country sized storms, and is an intelligent psychic on top of that, there's probably no single Ashnime trainer that can beat him, at least without extensive prep or plot induced idiocy.
