Nothing tried is worse than nothing gained.
Not much, since the DBZ characters blow up everyone else instantly. In a more protracted scenario though, it would go some distance toward countering various tricks.Even if it was telepathy what does it do in regards to this scenario?
That's debatable, but not what I was going for, and it doesn't really need to. There are multiple instances of characters demonstrating that enough ki power lets you resist psionics. This is corroborated by the fact that enough ki power lets you resist outright reality warping because it demonstrates that ki power is basically a universal defense if you have enough of it. Not one without limits, of course, but it is demnstrated repeatedly that it pretty much gives you a saving throw against everything.It doesn't translate to telepathic defenses.
