Why Bulma is useless in a nutshell.

   

    Doing things before a story begins doesn't make you important during the story.

    Doing things at the start of the story doesn't make you important for the rest of the story.

    Doing things at the end of the story doesn't make you important for the entire story.    

    Doing a few things during the story doesn't make you important for the entire story, especially when the things you do are brief and only amount to lazy plot devices at most.

    Doing something off-screen doesn't make you important in a story, because if it's off-screen, it's not an actual point of focus in the story.

    You're not getting any real focus or spotlight when the supposedly important things you do are brief or off-screen. 

    Being used for lazy plot devices doesn't make you important.  

    Constantly being used for perverted fan-service or misogynist gags doesn't make you important. 

    Being the parent, child, or relative of someone important doesn't make you important. 

    Oh, and having sex with mass murderers and getting knocked up by them doesn't make you important. 

    The plot in Dragon Ball is utter bullshit and only the fighting matters (if anything), because that's all people care about seeing.

    Nobody actually gave a shit about Dragon Ball in the beginning, and the series only became successful when it became more about fighting.

    Bulma doesn't fight, so she's worthless.

    Only fighters matter a fighting series. 

    If you wanted a series with truly important female characters, you'd just watch or read ones with female protagonists. 

    Bulma doesn't even come anywhere close to being one of the most significant female characters in fiction.

    Oh, and do know that Toriyama Akira was a degenerate pervert who drew a comic where a superheroine turns to prostitution after repeatedly getting raped. Not a surprise when he'd constantly draw Bulma getting sexually harassed and assaulted when she was supposed to be a minor. Did I mention that he said he'd like to spy on his daughter bathing as a grown man?
