The problem is that she looks like tryhard comittee designed shit, her personality is fucking retarded, she gets powerups like every goddamned person in super which cheapens them(this isn't just a problem with super, it's a problem with all media with "strong female" characters being handed power with no actual work see star wars), she's never had anything close to unique character building, masculine acting female fighters who are protected from things that the male fighters aren't always always shit the bed with the male and female half of the audience, and she's shoved in everyone's face even after we kept screaming SHE FUCKING SUCKS AND WE HATE HER STOP!!.
Take kale and add in "rape broly" and you have like...two of the most hated characters in DB in a long fucking while. I mean, kale is so shit that the character managed to kill hype for the Broly character outright.
This isn't me shitting or being a dick about it. This is a fact.
And just having her beat up won't fix this fuck up like it did with fucking videl. Even after that beating(which was a light slap on the wrist compared to what racoome did to a 5 year old gohan)
They can't even get away with that. People will see through it and know that they're being manipulated.
They can't do shit with her except pull a saber/lightning. Continuously lie to the audience stating that everyone loves the character and even create a bunch of fake polls.
