I thought the Six(6) Paths were the 5 elements (Wind,Fire,Water,Earth,Lightning), cause if you recall some episodes that ero-senin (jiraya-sama) talk about the six paths. And after watching the episode where kakashi gain the sharingan. And suddenly Tobi showned himself.
I jumped into conclusion that Tobi is Obito who's sharigan is not completed yet. And the only reason that Tobi recruit sasuke is to prevent any leak about another Sharingan Survivor who I believe have the ability to destroy the Konoha, and even if happens, Sasuke will be the villain who can do that as a sharingan user
.
But still I like the attitude of Tobi. Cocky yet cuddly
