Ehhhhhehhhh...
[looks super-sheepish, moves on, though admittedly that would be proof that Jaffur's heart is, as per his famous ancestor's pure... badass.]
I don't know about you, but my steak dinner started talking to me, I wouldn't eat it.
Yes, see
The Restaurant at the End of the Universe for reference.
But on the other hand,
that won't actually happen, it's not plausible. The steak dinner is not, in point of fact, capable of generating any argument that could persuade us not to eat it.
Where are those mobs of supporting combatants? Where are the Kaiju-busters? Every single Kaio-Ken Oozaru is as powerful as this 900 million dragon. We should be swarming him with hundreds of apes as powerful as he is and tens of thousands of lesser saiyans while the golden apes anchor the whole thing. What's the point of investing in Tactical Genius if you don't use it?
No matter how weak or strong the dragon is, the royals have by far the best chance of taking this thing down
without mass casualties and
without some kind of infohazard event blowing up.
So I'm pretty sure that "bring in the mob of support combatants" is
at best the Go To Hell Plan, say what happens if one or two of the royals are down.
Also, strictly speaking, I'm not too sure that all the Kaio-Ken Oozaru are in fact capable of hitting Kaio-Ken x30, the multiplier your'e talking about. Furthermore, there aren't necessarily very many of those in any case (because being one puts you on the equivalent of a terror watch list). And they probably can't all teleport.
