both madara and izuna had eternal

[epictobi]

What if madara gave his brother (tobi) his magekyou and they swaped and if the eternal grants more chakra explaining how izuna (tobi) lived so long....also this explains why tobi knos so much about madara U_U

 

[AP2k]

If izuna is tobi and tobi has EMS why does he not use it?

 

[Mugen Tsukyomi]

He wouldn't have it any more because he used izanagi.
