There have been multiple instances which Tobi desmonstrated to posses a strange body, and he made strange references to it:
- He is just "a shell of his former self" (also said by Itachi);
- When Kakashi asked, he said his goal would be to have a "perfect body"
- He claims to be "nobody";
- More recently, after he was revealed to be Obito, he seems to refers to "I" (as him) in some strange manner;
So, taking that in account, and that Obito has been around during the massacre of the Uchiha Clan, Itachi's death, probably during Madara's death... could it be that Tobi is an amalgamation of Uchihas?
Like this, but with Sharingans:
I don't see why he'd consider himself a shell of his former self (considering how noobish he was), and now he have Hashirama's cells + Haxx S/T (disregarding the Rinnegan), doesn't make sense
It's painfully clear that the character known as Tobi was intended to be Madara to begin with, guess Kishi changed his mind
and how would you explain him having kamui since his very very very first appearance arround chapter 250 (when the ring slips through his hand) ... i think obito was designed to be tobi since kakashi gaiden but kishi wanted to troll us into thinking he was madara

and thats why at the end , it looks like he was designed to be madara
Keep in mind that "Obito" can be translated as "Person about to be corrupted".
