Tobi
Itachi's Back story...
Things were going well for Itachi at Konoha until he and his best friend got into a fight over to last stick of pocky. It errupted into a fight that killed his entire clan. During the melee, Sasuke took the stick of pocky, ate it and left without anyone noticing. Only he survived Itachi's rage. Seeing that his clan was dead and could buy him no more pocky, Itachi left Konoha to join the Akatsuki- an organization that gives him a weekly "pocky allowance" of $23.15. He is partnered with Kisame, the only guy in the group who doesn't like pocky. This is a safety precuation to prevent a repeat of the Uchiha Pocky Wars that wiped out the clan.
