That's not exactly true. Muscular women in fiction still have feminine mannerisms and desires, and the best portrayals of such characters is when they mix the two elements together well.
Take my examples above. Aveline is one of the warriors of main character Hawke's group, and eventually becomes Guard-Captain of Kirkwall with your help. Despite this, she's quite lonely and yearns for a man to love her, but is painfully aware that she intimidates men with her looks. One of her companion quests has you helping her in wooing her fellow guardsman Donnic, whom she marries if you're successful. Seems pretty feminine to me and not exactly a man-hating feminist stereotype.
Bioware where famous SJW even before it was cool. They where after all one of the few who allowed protagonists to have homosexual romance between characters and depicted it seriously.
Jennifer Walters on the other hand, loves being the She-Hulk in contrast to her cousin, Bruce Banner, who hated becoming the Hulk. And who wouldn't love the fact being a super strong and sexy 7-foot tall green amazon? Plus, she gets plenty of chances to sleep around with guys, including a Greek demi-god. Again, seems plenty feminine to me.
She-Hulk on the other hand didn't begin like the character she is today. Her current image was pretty much an accident, as the character was created exclusively to avoid a potential licence loss AND NO OTHER REASON! Upon Marvel realizing they might have a feminist icon on their hand (they became rather sensitive after
the rape of miss Marvel 5 years ago after all), and after a few writers who managed to be woke and smart at the same time, only then she reached her current status.
Even with the above, she's curiously allowed to keep her sexuality , unlike her male counterpart that becomes as dumb blob of muscle and rage. So rather than becoming an inhuman monster, she becomes a different fetish.
Lets not forget that despite all the above better traits, she's still not considered nearly as popular as her male counterpart. Hulk is now a staple of the Cinematic universe, while She-hulk was only considered as a Netflix adaptation at some point, and they didn't even go through with that.
The Strong Female hero is mostly a recent thing, that has been done mostly as a PR stunt, as those movies don't seem to sell (or be) as good. The only two movies like that that sold decently are Wonder Woman and Captain Marvel, and both did because they had huge support from the cinematic continuity.
But we are getting off-topic...
Where where we?
Oh, yes! Muscular female game characters!
