I was drawn into it because of how it looks so much like early DBZ's art style; I'm almost surprised it wasn't animated by Toei. Needless to say, Toriyama designed the characters. Anyway, it's a pretty shit anime; I just skimmed through it.
A pervert's manga isn't science, dear.
Nah, Toriyama hates women. That's why the only thing Bulma ever actually does is be the butt of countless misogynist, sexist gags. And why he drew a comic where a woman turns to prostitution after repeatedly getting raped. And why he said he wanted to spy...
Lazy off-screen plot devices that fuck over the spacetime continuum and result in everyone on Earth being killed followed by the whole multiverse being erased. So, yeah, not useful. Trunks could travel back in time through a wormhole in a squirrel's ass and nothing would change.
Not important...
It wasn't important.
Doing one thing at the start of the story doesn't make you important. And lol @ you leave out the next part.
So, yeah, Bulma's worthless.
