I've just read 4chan on Sword/Shield, and guess what someone just data-mined? AZ's coming back and he's no longer super tall (he's normal-sized) and he aged a little bit. Got a new outfit too.
And so I just scribbled this one up.
You /do/ realize that this is just a false rumor. Happy April Fool's! rofl
AZ (Pokemon) belongs to Nintendo/Game Freak
