Honestly...
Can we just
accept that in-character, Kakara doesn't think Dandeer deserves to die anymore?
Dandeer dying isn't going to give me pleasure in-story. I get the feeling that for some people she's, like, a proxy for other characters they hate, or even real people they hate, and I can sympathize with that... But I don't think it's a good idea to get upset over a lack of opportunities to kill off a fictional antagonist.
...
Look, Dandeer did one very terrible thing,
I get that. It affected all of
two people, one of whom almost certainly deserved it and would have murdered or tortured his own family if it hadn't been done.
She did that after experiencing massive, mind-crushing trauma over a period of many years that seems to have badly warped her mind and attitudes, leaving her in a situation where she seems to have
believed that either her actions were in fact not harming anyone, or that her actions were necessary, or both.
Compared to the level of evilness of actual Dragonball villains, she barely even shows up on the radar. I'm not going to even try to list all the Dragonball characters responsible for hundreds or thousands of deaths, including those considered redeemable or even good.
Vegeta tried to
blow up the Earth, plus killing I don't even know how many people on Namek, plus other planets he depopulated in Frieza's name. Dandeer's level of actual
sins, in the sense of evil acts committed that reflect personal character deficiencies, is measured in, like... micro-Vegetas, at worst. Probably nano-Vegetas.
Most ki blast techniques tend to be redundant with each other. There is a reason Goku never bothered to name anything besides Kamehameha.
Yeah. Looking at Vegeta Style, the preferred techniques list consists of four "high-energy directional blast" attacks, plus Crowd Fighting. It's almost certainly the definitive 'blaster' style of martial arts among the Exiles, but if you aren't planning on fighting with blasts it's kind of useless.
For Kakara, the combination of collateral damage potential from long range blasts, plus the fact that it's hard to calibrate a ki blast so it
affects your opponent without killing them, it's counterproductive.
Vegeta Style is, appropriately, a good style for a self-identified "warrior prince" who expects to be stronger than his enemies but probably outnumbered by them, doesn't give a damn about collateral damage, and is willing to kill his opponents.
Yup.
Were that a thing, yes.
Piccolo style is mentioned because she hates it.
I'm curious as to why. You say...
Indeed. She tried it a bounced.
In-story is there a narrative reason for that? Or did she just roll badly during character creation or something?
I was under the impression that it was made for combat rather then a multipurpose tool? At the very least, we never see anyone try and use it for anything else in the show.
I think that's because most of the Z fighters are
really, really focused on combat utility or martial arts for the martial arts' sake. Most of them don't seem to have much in the way of gainful employment or ambitions in life beyond "be hella strong and cultivate your ki."
Goku doesn't use his superhuman strength and Instant Transmission to make millions transporting big expensive objects around the world instantly. Krillin doesn't use Destructo Disks to cleave through mountains for construction projects. Piccolo doesn't open up his own "fly your stuff into space" business and outcompete commercial satellite launchers.
So just because these techniques were developed with the intent of using them in combat, doesn't mean that's all they're for. Kakara isn't using Multiform for battle, but that's because Kakara has only fought two battles since she began studying Multiform, and she hasn't studied a combat style that would enable her to use Multiform to best effect in any case.
Kakara's Mom is so good at Satan Style that she can lose with grace and class.
Kakara's Mom once beat a computer at tic-tac-toe. As O.
Kakara's Mom can learn any style that doesn't require being green.
Someone once thought Kakara's Mom was wrong. Their body was never found.
A compelling theory goes that if Kakara's Mom is ever proven wrong, the Universe will retroactively change until she no longer is.
If Kakara's Mom doesn't know the answer, the question doesn't have one.
Hypothesis: Some of this may be because Berra is soooo Gokun (complete with raising a Goku-esque combat style to the highest level of refinement ever known among the Exiles) that his wife has spontaneously started channeling Chi-Chi.
So, like, that's the only thing we need to beat the Enemy? Get him one good time with the ki blocking technique? I am not sure it's as simply as that. Otherwise, there would be no need for any other technique.
Hypothesis:
The Enemy may not rely entirely, or may not rely
at all, on ki as we know it. Their powers may involve sorcery, for example, or may be some kind of totally unique and unknown thing.
What I take from that is we inherited both our fathers social/political brain, and our mothers academic brain. Then add our Ki brain on top.
From the sound of it, they're both
pretty damn talented at ki usage, too...
