First i was thinking Rinnegan.
But it would be a big ass pul,l and a ****ing senju boost wich make you almost godlike.
But i was thinking he might get the elder son's eyes just like on my ava.
because if im right the sharingan is some sort of evolution of this
this are the elder son's eyes
and this hatred made it to a sharingan.
So i may be wrong in this 1 but : why is sasuke showing His MS instead of EMS to tobirama
Is it because he is becoming a good boy ?
and the sharingan goes back to the form of elder son's eyes ???
(he might show his Ems later but only time will tell )
and it would be nice we dont know anything about these eye's yet
it would make sense because it seems the younger son is just like = naruto and hashirama
Madara failed in it so now its time for sasuke to be like the elder son
what do you guys think
( sorry for my english and horrible grammar.)
