I don't see Greninja returning, he'd have to have a massive role in any upcoming Pokemon Movies or Games, which I don't see happening, Charizard I find as an exception because he was a Gen 1 starter, arguably one of the most popular Pokemon and has been in every Smash Game evolving into his own character.
