OK. I recently made a big deal about the gender distribution of servants in the Fate universe and found that while people constantly complain that there are more female Servants than male Servants the reverse is actually true. The real reason people feel that way is that the female Servants get a lion’s share of the attention despite being fewer in number. There are a lot of reasons for that but the gender-bent Servants are no small contributing factor. So in order to counterbalance that I made a list of awesome historical characters that would make great female Servants and you would not have to touch their gender in the slightest.
One quick rule: There is currently a supposedly data mined list of characters who have code in the Fate/Grand Order game but have not been revealed yet. So while that list has not been fully confirmed yet there are some magazine spoilers and leaked images have shown that at least part of the list is correct. With that in mind I won’t pick any characters from that list as I’m going to assume they are already in Fate/Grand Order. So no Cleopatra, Helena Petrovna Blavatsky, or Tomoe Gozen. At this point they are practically canonical.
