The larger issue at hand isnt what can happen if Zangya is discovered. Those are easily predicted. What needs to be listed out are the potential methods to discover her in any relevant fashion, and by looking at that we realize a few interesting things:
- The Kais can discover Zangya through typical Power Detection methods
- The Scouter Network can pick up on her rather impressive Power level
- Observing her directly and realizing that she is, indeed, the last remaining Heran.
Fairly straightforward, tbh. And just as straightforwardly circumvented.
The first is, naturally, the Kais. They are also the one that we can do the least about. They are, for their part, already fully aware of what's transpiring above Earths atmosphere.
Ergo, attempting to hide things from them is a wasted effort. But what would they do about that? I'll go into that in a bit.
The second method is the Scouter Network. Ordinarily, this wouldn't be an issue since Broly could take similar measures to match the ones that were taken regarding both his own power level and Lord Coolers.
However, there is a bug in the system. Namely,
Toddler, who is still at large. Now fortunately this is a problem that can be taken care of
right now courtesy of Bulma.
This also addresses a larger problem in finishing up the last remnants of the Machine Mutant War, but that can be discussed in a bit.
The third, and last method of detection is visual observation. Which can be handled by a simple combination of solving the second potential issue and keeping her out of sight of relevant individuals either through isolation or through disguise or some other method of subterfuge. Options are on the table, so to speak.
Now then, we come to the repercussions that are immediately observable. The first is the Kais.
They did not intervene. Nor, for that matter, have we been informed of an ongoing bounty on the heads of the Herans.
Like what happened with Pikon. Now then, we can assume that this means that whatever interest the Kais held in them wasn't something particularly urgent since they seemed largely content to allow Broly and Cooler to try and handle the situation. Which means less an existential issue, and likely something more tied to just how inconvenient someone of Bojack's Power and potential flying around acting like a tool was for the universe at large.
What this means is that, as far as the Kais are concerned, Zangya's continued life and death likely isn't that big a concern to them now that Bojack is out of the way. If it's an ongoing concern, one of the Kais will naturally reach out to us directly or just have Kami continue in his role of Divine Whipping Boy and have him relay their messages and requests to Broly through him.
Now that just leaves dealing with Toddler's interference and him acting as a Ghost in the Scouter Network. Something which Bulma is well-equipped to handle. This also lets her free things up so that countermeasures against Zangya's power level being discovered can be put into place. Which was a gateway to ensuring that the visual discovery method wouldnt be pulled off regardless.
tl;dr we go back to Capsule Corp, work with Bulma to discover Toddlers location and root him out of the Network while also killing him like the bug he is, before then proceeding to mask Zangya's power level and figure out how to best use her as Broly's Minion-in-Chief.
A vote which encapsulates those issues along with other ones I missed would undoubtedly be the most ideal.
