1. Anyone who isn't Kaguya does. Obito wasn't a perfect Jinchuuriki and he was using the god tree to do the Jutsu.
2. The Rinnesharingan
3. No it actually doesn't you retard

, you need to learn how to read. She possesses all 3 doujutsu powers, she is the progenitor of chakra. Still doesn't change the fact she used The Rinnesharingan to cast Inifinte Tskuyomi, or are you going to say that eye is now a sharingan?
4. "Madara awakened a 3rd eye on his forehead" The Rinnesharingan. SMH you're stupid.
5. Her 3rd eye is the Rinnesharingan not a sharingan. Obito was using the god tree to cast infinite Tskuyomi. Kaguya is the Juubi so why would she need anything else. Madara to get Kaguyas powers needed 2 Rinnegans to get the 3rd eye, The Rinnesharingan to cast infinite Tskuyomi. Otherwise he wouldn't have bothered with the whole capture the Bijuus and used his regular old sharingan powers like you claim

.
Rinnegansharingan = Infinite Tskuyomi
