yeah, It would be cool to see Kiba's dad, since we have only seen his mom, who looks pretty much like him, except with eye liner. His sister is the butt of many jokes on irc, which I won't repeat here.

I don't know about Naruto's dad showing up though. Perhaps in Naruto's mind. Naruto goes to call on the Kyubi again, but Yondaime is there and give him some of his chakra instead
