Just wanted to make this thread clear up an infectious misconception about madara's clones being shown to have rinnegan and then deactivating it to use a sharingan tech.
The misconception stems from here.
As you can see here is the picture of a madara CLONE he provided which never showed any signs of ever having rinnegan activated in the first place
This picture, one which was ignored for what ever reason, displays the original madara with rinnegan still activated
Here is the original creating the clones, the one with the RINNEGAN EYES
Madara never deactivated his rinnegan after activating it during his fight with the kages.
An argument commonly used against nagato's eyes being implants is that he is never seen with them off, and it is therefore assumed that he cannot deactivate them.
Another argument is that madara's clones can use non sharingan eyes therefore so can madara, except his clones may very well have never had had the rinnegan eyes in the first place, as they were never shown to.
Madara's rinnegan eye clone that tsunade attacked never deactivated it's rinnegan either, meaning that his clones were never shown deactivating it.
As you can see here his eyes are only black because tsunade pretty much destroyed the edo body, meaning that it needs to regain it's correct form before madara's soul can become active again, hence why the kage's tried to seal the clone.
He made 25 wood clones with sharingan only eyes, most likely due to chakra consumption, 25 rinnegan wood clones would be too excessive.
Madara is seen using top EMS techs while having rinnegan activate the notion that he would deactivate rinnegan for the sake of a MS genjutsu does not ludicrous in every way 100%.
IMAGE ISSUE SHOULD BE FIXED
