Can Sasuke's rinnegan/sharingan deactivate?

[Styles]

ofcourse its permanent did nagato's eye disappear after his death NO IT DID NOT and you really can't compare Shringan and Rinnegan

Naw man those wasn't Nagato's eyes they was Madara's and he could switch back and forth.

 

[~Sasuke~]

It can deactivate, but Sasuke will keep it active during the duration of the fight.

Who wants to see his regular eyes?

anyone he fights does

No need to deactivate it in a war

 

[Xāvî1]

EMS can be deactivated but not the rinnegan.
