Bee: That wack yo...
Naruto: You're one? What does "one" mean?
Tobi: I am nothing more then a combination of shinobi. Shinobi who are manifested by pure hatred. Some of which, you know of.
Naruto: ...? Wait a second...
Tobi: Starting to catch on? That's right...Akatsuki itself.
Bee and Na
Tobi: I take the abilities of shinobi's who die with hatred inside of them. In the beginning, Madara was my first victim. His ability to enter and leavedimensions was part of my eye, the sharingan. Akatsuki was my next goal. Filled with rogue ninja's of the highest caliber, this was perfect for me.
