The fox

[Vilstar]

Yeah, so i got to thinking this after seeing Gaara transforming into the Shukaku and Naruto and the Boss Frog transform into the fox. If there are creatures like this, do you think that the fox was also summoned like this? It says that the fox just appeared, so it's possible someone very powerful wanted to destroy Konoha. Maybe that person is the leader of the Akatsuki (sp?) or something like that. I dunno, just a thought. Would be interesting to see the guy that could/would summon the fox.

I dont think someone could summon the Boss Fox because hes sealed in Naruto, but that would make senice* about the great power of the Fox. because Toad boss and snake boss would seem like alot to handle for a town without equal power to fight it. the snake boss was said to be the kind of guy to eat even his master who summoned him if he know he could not use he jistus* to defind him self. So maybe some Powerfull guy had a fight with the 4th and in a last ditch try to win he summoned the fox for him to fight, but he was weakend by the major summon and fight before to stop gettin eaten by him. In the would of naruto their seems to be Lots of Animal types to summon. just think if their is a Boss Dog/wolf that kakashi can summon if need be. But it dose seem that not all Boss animals are big. remember the 3rds boss ape? it was Reguler size.

If Kakashi could summon Boss creature, that would put him on the same level as the Hokage and the Sennin. Naruto could only summon the Boss toad because he has the chakra of the fox. The monkey god could change size and transform, if he was his normal size he would probably not fit in the barrier.
