Why are female characters who can solve things without anyone’s help hated, but male characters who are perfect at practically everything are loved?
Batman is an example. Batman is a human being with a brilliant intellect, which is not a problem, but being a human being without powers, he manages to be more intelligent than aliens superior to humans, he manages to be a MASTER in all martial arts and no matter who the opponent is, he is always prepared and can win. Any writer who dares to create a female character with these characteristics would be attacked and called woke
There are many other examples, just watch any Japanese isekai anime. The protagonist dies and is reincarnated in another world with unrealistic powers and abilities. Out of nowhere, the boy who used to just stay at home masturbating and playing games is able to use all the magic and martial arts. Just by being born in another world, the protagonist is able to defeat wizards who have spent centuries training. And even though he has never picked up a sword, he is able to defeat dragons and swordsmen with a single blow
Any writer who dared to create a story with a female protagonist with the same characteristics would be accused of trying to push an ideological agenda and their character would be considered a Marie Sue.
Can’t say I relate or that I’ve watched much isekai. The only I’ve followed for a while was Overlord and it doesn’t fit your bill that’s for sure. Momonga is overpowered but morally mega flawed, which is precisely what keeps the plot interesting.
Isekai genre is kind of getting stupid bloated, and sadly an overwhelming portion of it is what’s come to be known as “power fantasy”, in which the main character, is intentionally made with as little personality as possible, because the writers believe that allows people to mentally “self insert” themselves as the MC.
Which I have to say, most people are considering the genre pretty tired, to the point where many of them are starting with paordies of the genre.
