Sharingan and Rinnegan are separate

[BlinkST]

I've touched on this idea many times now (Although I'm not very active on this forum).

The idea that the relationship between the Sharingan and Rinnegan, is not that of "Pokemon evolution". That is for example, like when Bulbasaur evolves into Ivysaur, and can use all of Ivysaur's attacks. That's not what happens with a Sharingan "evolving" into the Rinnegan, because the Rinnegan is not a permanent change, like the Bulbasaur - Ivysaur change. The Rinnegan is more like a Digimon evolution: you can evolve, but then go back. In other words, it's a transformation. Basically:

Sasuke doesn't have a Rinnegan, or Sharingan. He has an eye in which these ocular jutsu have been awakened, and he can go back and forth between them. This means the Rinnegan is not necessarily a "progression" of the Sharingan. It's more like another portion that has it's own set of powers. It's like how Naruto got Biju mode, but still used Sage mode and even mixed the two. Actually, Biju mode allowed Naruto to gather natural energy even quicker.

Similarly, the Rinnegan's powers mixed with the Sharingan, such as with the Susano'o that can block light.

The Rinnegan isn't necessarily stronger than the Sharingan, and vice-versa. But, if the two are used together, they can be unstoppable. This manga has commented many times on this. Specifically:

And now again with Sasuke.

Even though his Rinnegan can still use his pre-existing powers, he still makes it a point to separate the two, and goes so far as to reactivate his right Sharingan to carry out the Chidori. Why do all that if the Rinnegan is supposed to be an "evolution"? Because it isn't. Remember: all three ocular powers existed at the exact same time.

None of them "branch" from each other, nor was there ever ever an "ultimate eye", as much as there's an "ultimate being" with all the eyes. They each have their own special abilities.

I understand what you are trying to say here but isn't Sasuke's Rinnegan a special circumstance? What I mean is it isn't exactly the same kind of Rinnegan as say Madara awakened or the one Hagoromo had. (being just the ripple pattern with no tomoe)

In the case of Sasuke's Rinnegan I dare say you are correct. But if you noticed when Madara used his, he switched between both Sharingan and Rinnegan to use their abilities respectively. Whereas we just saw Sasuke use Chibaku Tensei, Preta path absorbsion and Amateratsu all from his own Rinnegan.

So I think you are right but only in the case of the 3rd eye rinnegan (juubigan if you will) just my guess though.

That's never been shown. The reason people insinuate that, is because:

One of his Mokuton clones placed the Raikage under a genjutsu. We never saw the eyes of the clones while Madara made them, so there's no way to know which eye they were made with.

Whereas we just saw Sasuke use Chibaku Tensei, Preta path absorbsion and Amateratsu all from his own Rinnegan.

We also saw the same from Madara.
