Everything Mega Diancie can learn, split by learn method: what comes with leveling up, what from a machine and what only from an Egg, from a parent that already knows the move. Order and availability differ between generations — choose a game below to see the moveset exactly as it is there. The same move may appear in two sections at once, because in one game it is learned by leveling up and in another from a machine; the counter 62 counts distinct moves, not rows.
