Pretty sure I accounted for Hassan of Hundred Personas in the list I made in the first post, being:
Rename/alias assassin_(fate/zero) -> hassan_of_hundred_personas_(fate)
imply child_assassin_(fate/zero) -> hassan_of_hundred_personas_(fate)
imply female_assassin_(fate/zero) -> hassan_of_hundred_personas_(fate)
Of course, the alias would have to be done first before the implications.
Of Hundred Personas’ identified personas, only Female (or “Asako”) and Child are distinctly depicted through in-game portraits, as they’re the only female ones seen. There are other ones, as stated in HP’s Interlude segment in FGO, but you either don’t get to see what they look like, or they’re the generic Hassan enemies players encounter in the game. Generally, the male personas look so similar to each other that it’s nearly impossible to identify a specific one.
To be specific, generic HP personas encountered as enemies are Zayed the Base, Gozul the Strong and Makul the Quick. Along with those three, a fourth one called Dew Painter is mentioned in HP’s interlude segment, but not actually seen. Child Hassan is referred to as Little Hassan, but I think the Child Hassan tag is good enough as it is.
The interlude is on YouTube if you guys want to review it. I’d copy and paste it, but I don’t know how to do that on an IPad. Sorry. :/
