2. He soon dies of his wounds from the battle, regardless of his use of Izanagi, both explaining why everyone thought Hashirama killed him and why no one knew he had awoken the rinnegan.
3. Before his death, Madara channeled his final efforts into creating an avatar using his newly gained rinnegan (which can give life) and/or Izanami (a jutsu that determines fate) and stolen mokuton abilities. This avatar, henceforth known as Tobi, is to continue his legacy, and is imbued with Madara's memories and living will.
4. As a creation of the sharingan and mokuton, Tobi may in fact be a precedent for Orochimaru's research into Mokuton's ability to enhance the sharingan's power. We know at he at least formulated some very astute hypothesis regarding Madara's abilities (his true prime, which included Hashirama's dna)
6. Mokuton is the reason Tobi's body is both able to survive grievous hits (from Yondaime and Torune) and regenerate lost limbs (by using the stuff grown out of the Hashirama clone back at his base.
7. before the Uchiha massacre but AFTER Kakashi's gaining of the sharingan (very soon after), Tobi retrieves Uchiha Obito's remaining eye, and gains the same type of space time manipulation as Kamui (the latter being Kakashi's activated Mangekyo jutsu). Because his body contains mokuton material, which is shown (via Danzo) to augment and shorten the cooldown for sharingan abilities, Tobi's spacetime jutsu is in fact the same as kamui (similar to how Danzo's mind manipulation ability is the same as Kotoamatsukami)
8. Post Uchiha Clan massacre, Tobi gains access to a fresh supply of sharingan eyes (minus Shisui's eyes, which he coveted)
9. Tobi is at least aware that he is not the real Uchiha Madara (despite claiming to be). His claim is at least partially legitimate because he possesses the memories of Madara and shares the same goals (having been created by the former)
