Chi-Chi in super dragon ball z is far from what I'd call faithful. They took a lot of liberties with her moveset.
The thing is, DBFZ is going to have a very small roster for a dbz game. About 25 or so characters on day 1.
That means that some popular characters are going to be missing.
Broly, Hit, Beerus, Raditz, Goku Black, Adult Gohan, Videl, Hercule, Android 17, Master Roshi, Janemba, Bojack, Bardock, Android 13, Garlic Jr, Kid Buu, Super Buu, Dodoria, Cooler, Zarbon, Dabura, Gotenks, Gogeta, Vegito, Goten and Trunks to name a few. Many of these characters won't be in the day 1 roster or even in the dlc.
And you're asking for one of them to give their place to Bulma. A character that has never fought in the entire series. That doesn't know martial arts, doesn't know how to fly or know how to produce ki blasts.
All because she's female. Literally for no other reason. You want her in, at the expense of fan favorites, because she's female. Don't tell me it's because of what she does in the source material because, again, she doesn't fight. She doesn't do anything other than being a plot device that gets the fighters to where they need to be next. That's it. That's her job in the entire series. She's there as the owner of the dragon radar who goes along for the ride and as the scientist who creates the next machine that the fighters need to go back to the past or namek.
But I guess I just have a different mentality than many resetera members when it comes to dragon ball.
