On the issue of the origin of Gaara's sand shield? Well, since you said that you thought it was his mother's love (the lie told to him when he was younger), and it's actually not, I think that about rules out all the options except that the automatic sand shield is the Shukaku's work, how it protects itself.Originally Posted by JaySee
And, bringing it back around to the earlier discussion, that point and the fact that Shukaku would possess Gaara whenever he went to sleep indicates that Chiyo's sealing of the Bijuu into Gaara was NOT as good of a seal as the 4th's of the Kyuubi into Naruto. Then again, Chiyo is still alive and the 4th is said to have died in the sealing process.
But whether that means that Kyuubi is stronger than Shukaku?... honestly, I'm with Assassin on this one; by anime logic, the Kyubbi is the strongest simply because it's the one sealed within the main character.
