Susanoo is manifested initially by dual Mangekyou, but once manifested it no longer needs the eyes. According to the legend, Susanoo was borne from the nose, so i guess it makes sense that it's technically not a dojutsu.

In other words, Susanoo is a technique that originates from the brain, not the eyes. Indk21 wrote: Sasuke's sharingan just has his unique look and its the same as Madara's and Hagoromo's Rinnegan. Sasuke's eye has simultaneously a Sharingan and Rinnegan active. When active this way, the sharingan manifests as tomoe in his Rinnegan. This is why it's simply named a Rinnegan most of the time, since it is. It's not a new dojutsu, although it's obvious from the look that the two dojutsu manifesting together is a step towards the Rinne Sharingan.

Indk21 wrote: I think that each Rinnegan have the same abilities (Tendou, Gedou, Ningedou, Shuradou etc.) The paths are Nagato's own invention, i think. While certain techniques are available to the Rinnegan users, and certain others can be taught, the Rinnegan doesn't innately possess these powers.

E.g. Animal Path is just an extension of his Six Paths, since they too have the black spikes and corresponding rinnegan, suggesting that he found strange animal corpses and manipulates them. The Six Paths technique itself is just Nagato making use of black rods and the Human Path's mind control.

When faced with Amaterasu, Madara absorbed the flames like it was nothing, suggesting that Preta Path's ability is also not a pure rinnegan ability.
