Genghis khan (as a rider or archer I’m honestly surprised that he isn’t already in the game due to just how famous he is he’s pretty much Iskander but on steroids )

Sun wukong (this guy has plenty of summon ideas like lancer, rider, caster, and berserker like he’s been mention and had a canonical design and np like what’s the hold up he would be so OP as a servant)

Ur-nungal (this one is a bit iffy since their isn’t a lot of Info on him but come on the child of Gilgamesh not in fate is a crime he isn’t even mention. The only major thing I can find on him is that he build a temple for the god Enlil(?) so I imagine he can be a caster with a similar np as mash)

Hammurabi (this one is definitely a ruler for me like without a doubt. like a true Babylonian king that help shape modern law and funfact in the CCC Gilgamesh route gilgamesh mentions him (very briefly) why isn’t he in the game???)

Bonnie and Clyde (easily archer class the infamous duo would have been perfect in the American singulararity or some kind of lost belt. Also I have a head canon that Bonnie is the crazier one and Clyde is a absolute simp for her)

Julie Daubigny (the princess of opera herself that bisexual sword swiging crazy French women would fit perfectly in Chaldea like the mad women got away with the death penalty twice cause the king found her funny)

Goliath (this one needs to in the game just for David can be scared shitless)

Lugalbanda (He should also be a servants like either a lancer or rider his legend is older then Gilgamesh considering he is Gilgamesh dad he was mention briefly by Gilgamesh in the ccc and extrella games like this total chad pulled a goddess where is he type moon)

Davy Crockett (honestly I just want more American servants call me bias)
