I was just wandering if there could possibly be ties between the summons and demons in Naruto? It's obvious both types of creatures dont live in the same planes of existence as humans (Gamabunta saying something about it being nice being summoned back into the real world or something when Naruto first calls on him)
Could the summons be like a step below the animal demons and if they perform a task or live long enough get raised, or evolve into demons. Weak ones of course since it seems the older a demon is the more powerful it becomes (Kyubi and its 9 tails, each signifying a hundred years of life I think).
This is complete speculation with nothing whatsoever to back it up but it does maybe seem feasible (to me anyway [img]i/expressions/face-icon-small-wink.gif[/img] )
So what are your thoughts?
