Long story short, the 5 Kages are fighting a edo tensei madara who has both the Mangekyo and the Rinnegan while Sasuke's gained the Eternal Mangekyo Sharingan and Naruto, Bee, Kakashi, and Gai are up against Madara/Tobi and the revived 6 edo tenseI tailed beast hosts who have both a Rinnegan and a Sharingan like Tobi now.
THIS IS SPARTA!!!!!!!!!!
