Virtue signalling means introducing minority characters as the best of the best.
But its ok when we have white child geniuses in comics, which there are many of.
If a white child genius was introduced as smarter than the canon smartest character, I'd still be annoyed. It has nothing to do with being white or black or male or female, it's that you don't debut at the top. And it's pretty evident that she's being toted as the smartest simply because she's a minority character.
They should've introduced her, let her develop her own following, and casually allowed her to surpass Tony Stark in a manner which felt organic. Instead, they threw a 15 year old girl into a metal suit, called her Iron Man, and proclaimed her smarter than the original. That's not a good way to make friends.
I wouldn't want to meet the 17 year old who could outfight Batman.
are you complaining about finctional characters making friends?
