Children like Bulma using guns is just because Toriyama was/is a model gun collector and he likes to draw them. There isn't any information of Bulma undergoing any combat training
I supposed this was the reason.
Guess if they make a more gunplay character it would have to be Mai, she could be the Mastodon Sentry of this game, lol.
I'm sure it's been mentioned, probably a few times, but Dragon Ball Z is the most basic of basic kids' power fantasy mangas that is made primarily for an audience of boys aged 15 or younger. I'm not sure how reasonable it is to expect much in terms of representation.
Cause Super added a ton of female fighter options, 2 of them (3 if you count their fusion) topping "most wanted character" lists.
Why do people keep ignoring this?
