Remember during my old account where I would repeatedly bash Fate's idiotic idea of gender swapping historical figures and their own male characters? Well, my buds sent me something that impressed me today.
I present to you, Hassan
From what my friend told me, this guy is a pure badass. Essentially he was an assassin during a religious war that died defending his soldiers to the last breath. He's so pure that he warded off the entity of lust itself (probably a loli). From what he said, he has never truly lost a battle. That means against men, other servants, to even gods!
Only thing that brings him down however is that it's said he appeared once in the series and that's it. I don't even like Fate but I would be down to see this guy get his own spin off show. Also there's a cool alter version of himself called Hassan of the Hundred Faces where he's able to reincarnate himself into his fallen soldiers.
