if u had a deamon inside u what would it be and why?

id have Naruto's Kyuubi, or maybe Gaara's shakaku.

The Shakaku because it made Gaara strong, also the Kazekage :)

The Kyuubi because it was the only one NOT captured by the Akatsuki.

either juubi from naruto or the great laviathan from yugioh XD because their awesome

This question is strange. Do you mean a demon from Naruto only, or any demon whatsoever?
From Naruto i wouldn't know - none seem to fit me as myself, but people have told me i fit the personality traits of Gaea or Gaia, ancient greek goddess of earth and fertility also known today as Mother nature. It's said that in even earlier times, the greeks worshipped Gaea out of fear, as they believed her to be a demon from hell who had given them rich land for their souls. Only by worshipping her did she allow their souls to remain in their bodies until death. But around two thousand years after that in the ancient greeks we've learnt more about, she just becomes a normal earth goddess who was the mother who gave birth to everything in exsistance.

i would have the nine tailed fox because it's the most powerful and awsome
