Unless you have a plausible explanation like I do for the fic the above image comes from!Kyuubi itself, yeah. But Naruto would die if Kyuubi fully broke loose. Just 3 or 4 tails' worth of power, and Naruto's almost toast.
But yeah, the Kyuubi could waste pretty much anyone in Dagonball. Z... eh, he'd start hitting trouble, but DB would be a cake walk.
Someone brought up the "DB/Z characters can blow-up planets" thing earlier. Sure. They can do that. But I've never seen even Vegetto wave a hand and cause a hurricane. The Kyuubi's a walking natural disaster. Just moving can lay waste to huge areas of land.
The loud, showy, flashy kind.I mean really, what "ninja" wears an orange jumpsuit?
Let's also not forget that Naruto does not feature 'traditional Ninjas' in the slightest. These villages aren't training the next main character of Shinobi.
And if you really want to get into comments like that... what kind of Pirate isn't able to swim (exenuating circumstances change nothing, he still can't swim XP).
Anyway, as for how various Naruto characters would do against DB/Z characters... it would depend on which Naruto characters at what point in the series are fighting against what DB/Z characters from which point in the series.
Let's also not forget that the DB/Z characters have never dealt with moves like those the majority Naruto characters use. Roshi wouldn't last 2 seconds against a Sexy no Jutsu. A well placed Rasengan from even pre-timeskip Naruto could probably OHKO a fair majority of early DB characters. And I think anyone short Nappa would have an issue dealing with the likes of the Sannin.
And let's also not forget that all the power in the universe wont help you if you're trapped in a Genjutsu. None of the DB/Z characters would stand a chance in Hell against any Genjutsu.
