for reasons I don't feel like spoiling or explaining (which the show doesn't explain all that clearly either)I actually find this series homophobic now so I'mma keep my commentary to a minimum...**shrug**
I just Preffer Bulla because it's more in line with Bulma's family names being Misspelling/mistranslations of underpants , like Bulma=Bloomers and Panchy=Panties
it's because they re-hired a bunch of Z's old animators and adjusted the style to match the old show's style
Toei finally realized the fans weren't happy with the UNPAID INTERNS toei had animating the first few arcs
