Tobi has both of his or err...Obito's eys.
Itachi is in his prime neither him or Tobi will suffer drawbacks from over using the MS.
Sasuke has his EMS.
Madara is at his prime and can only use his EMS.
Battle takes place in Konoha village when it was hit by Pein's Almighty Push.
So who is the Top Uchiha?
