Common mistake but people fail to realize there is no special Rinnegan ability. Sasuke for instance, ppl think the amaterasu control is different than his ameno.... nope he's using the same jutsu. Just due to variation in application he names it differently. This is speculation but I think amaterasu can also be classified as a s/t ninjutsu. Summoning flames, Reverse summoning flames and partial flame summon to put it simply. Limbo is considered to be a Rinnegan ability due to it being used only when Madara received it, but in actuality because it wasn't his actual eyes he couldn't. Obito stated it over and over just b4 Madara received both that the true power of the sharingan can only be obtained with both eyes. The eye at all stages has the special ability the development and evolution only further the potency of given special ability. That's why he could only do basic MS abilities until he revived and obtained both his real eyes.
Nope. Sorry bro, but even jin no sho (the 4th databook) states limbo and amenotejikara to be Madara and Sasuke's rinnegan abilities.
Plus, there is actual dialogue in the manga from the characters themselves that confirm this.
It was either chapter 674 or 675 that was literally titled "Sasuke's rinnegan". In that chapter, he uses amenotejikara for the first time, and he says "so that's this eye's power", implying that it was a new technique to him and not something that he could use before. In the fight against Kaguya, Sasuke also goes on to have a certain conversation with Naruto:
*Sasuke warps to Naruto's location after almost falling into the lava*
Naruto: "That's right, I forgot you could move all shunshin-like now"
Sasuke: "Like this platform (referring to the truth seeking ball platform that Naruto made for him), it's thanks to the six paths power"
Now what did Sasuke awaken after obtaining the six paths power? That's right: The rinnegan!!
As for Madara, in the chapter titled "Limbo Hengoku" (forgot the chapter number), Madara said to Zetsu:
"If I use the true power of the rinnegan, this (battle with the bijuus) will be over in a few seconds"
Then he summoned the mazou and then used limbo and soloed Naruto, Bee, Gaara and all 9 bijuus with ease.
Notice he said, power of the rinnegan, and not of the sharingan or the mangekyou sharingan?
Also, with limbo, only those with six paths chakara can attack a limbo clone, and only those with rinnegan (a rikudou powered dojutsu) can see it. Those with RSM can sense it.
Now tell me, why would a mere mangekyou sharingan technique have so much to do with the six paths powers and the rinnegan and all that stuff?
Not to even mention that Momoshiki doesn't even have a sharingan, but he has a rinnegan and he has his own rinnegan abilities.
Clearly the rinnegan does grant unique and special abilities.
On another note:
What is with all the rinnegan haters/nerfers around this base?
First we get those two users who try and say that only Nagato can use the six paths techniques and that not even Madara can use the techniques that come with his own freaking eyes. Essentially, those two are trying to render the rinnegan as a weak eye with only about 1 or 2 abilities.
Now you're here and trying to say that rinnegan doesn't grant unique abilities! I wouldn't be surprised if you agree with them in that only Nagato can use the six paths techniques either.
What the hell are you people trying to do to the rinnegan?! Between you and those other two, we might as well just call rinnegan a contact lense and announce that there are only 2 great dojutsu (sharingan and byakugan), because if the writers were to listen to you three, then the rinnegan would be just about freaking useless!
P.S: For the other two users who I referenced (you probably know who you are), I already have you ignore listed.
