No , not because it takes huge chakra , he chose it because he can't deactivate that !He just closed his eyes like Kakashi when kakashi newly used MS because it takes a huge chakra and due to both eye's different vision
Thats mythrecharge huh... So that might be a draw back to Sasuke's powers, recoup time. Then what's Naruto's? As far as I can see Naruto has unlimited power.
I would have thought that Hagoromo's chakra would be immence. Even half of it, I think would be as much if not more than Maderas.Well, I have never seen anyone deactivate the Rinnengan so I am not really sure u can. Also, Sasuke is using the an eye which > Rinnengan while only having half of Hagoromo's chakra so it probably drains more chakra. So Sasuke is probably closing his eye to save conserve chakra
Madara before attaining attaining the Juubi or after?I would have thought that Hagoromo's chakra would be immence. Even half of it, I think would be as much if not more than Maderas.
