You know what I wanna see more of? People actually acknowledging that men are naturally stronger, faster, & have more stamina than women.
So, in stories where a woman fights a man & is supposed to come out the victor, it'd be nice to see these women use methods that would IRL help a woman win in a fight.
Things that utilize a woman's natural strengths over men, such as flexibility, agility, balance, dexterity, & ability to change direction at a moment's notice.
Because of all these things, women are naturally better at gymnastics than men, so fighting styles that would flow well when paired with it would likely be best.
Also styles that involve using your opponent's strength & size against them. Something that allows women to escape or dodge holds.
I've seen Judo, Brazillian Jiujitsu, & Aikido recommended to learn how to throw people bigger & stronger than you. There's also Muay Boran, which I think is the self-defense version of Muay Thai.
I've seen someone recommend Jiu Jitsu as having the best technique to use in order to weasel out of a grab & then run.
Apparently in Judo, you learn a lot of powerful techniques to take someone out from the floor.
I've also seen someone say that, if you're looking for a good dojo, to not go with any that focus hard on competitions as, apparently, they're more likely to have removed so much from the actual arts themselves that they're all-but-useless in real situations.
Add all this to the typical Women's Self-Defense where it's recommended you go aggressive for the eyes, nose, windpipe, & groin. As well as several escape maneuvers.
Now, in a fictional world, I'd like to also say gymkata or Martial Arts Rhythmic Gynastics would be good things to learn. At the same time, I don't know if gymkata is even a real thing or if it's just an old comedy movie that was then referenced in a Lego movie.
However, I would like to think that if it did exist, it'd be the sort of martial art that would cater to a woman's strengths specifically.
That, plus Bellet Kenpo & Acro Ballet.
Either way, don't just make the woman stronger without an explanation. Instead, make her skilled in ways that specifically allow her to fight against men.
