Too easy.



I'd had a theory that there aren't any male alicorns is because...one hasn't emerged yet. But if one did, Shining Armor would be the most likely candidate.



Sombra might have, if he didn't go down such a dark path. It seems that each alicorn faces their own internal darkness, either before or after their ascension. Luna had her Nightmare Moon period, Twilight went batshit insane.
