Eye of the Moon Plan

The is Madara Uchiha's plan, which seems to involve using Sasuke Uchiha to synchronize with the Demonic Statue of the Outer Path, of which holds seven of the nine tailed beasts gathered by Akatsuki. Madara notes that after Sasuke has failed to capture Killer Bee and the Eight-Tailed Giant Ox, he has been cautious for too long, and that it is time to emerge from the shadows and commence with this plan.

The Plan
Madara's plan is to gather all the Tailed-Beasts in order to fuse them back into their original form, the Ten-Tailed Beast. He will then become the host of the monstrous being, letting him gain immense power and so that he can use the moon, the Ten-Tail's body, to cover the world in an "Infinite Tsukuyomi," letting him control every living being, creating a world without hatred nor conflict.
