A brief note on this book's setting regarding Uchiha Madara's Eternal Eye: the original work never explicitly stated Madara's Mangekyo abilities, only the abilities of the Rinnegan. Although I have not watched Boruto, I looked up some information online. Only Otsutsuki Toneri, a descendant of Kaguya who lived on the moon—the younger brother of the Six Paths Sage and a descendant of Hamura Ōtsutsuki—awakened the ocular technique Golden Wheel Reincarnation Explosion, an ability related to controlling gravitational and repulsive forces.
The extraterrestrial Ōtsutsuki invaders, meanwhile, had never used abilities involving gravity or repulsion. At least, I could not find any records of them doing so, so I will assume they did not have them.
Therefore, I set Madara's Eternal Eye abilities as the Power of the Six Paths and Yin-Yang Power. This refers to the Eternal Eye, not the Mangekyo. The Power of the Six Paths consists of the abilities wielded by Pain, while Planetary Devastation is performed through Yin-Yang Power. Tengai Shinsei should essentially involve using immense gravity to draw in massive rocks from outer space and gather them together. I treat it as a variation of Banshō Ten'in, only with far greater consumption; Nagato did not have enough Chakra to use it. As for Madara's unique Rinnegan ocular technique, it is Limbo: Border Jail.
The specific reference is that Sharingan ocular techniques can still be used even after being transplanted into someone else, such as Kamui Kakashi, Kotoamatsukami Danzo, and the Kotoamatsukami Crow—the one Itachi gave Naruto. Therefore, Nagato could also use the Power of the Six Paths and Yin-Yang Power.
As for the special Rinne Rebirth, I define it as a combination of the Human Path and Naraka Path. It belongs to the Power of the Six Paths, but its consumption is enormous and can even drain
