madara uchiha is not tobi zetsu said that tobi is ralatively young. Madara uchiha is probably over a hundred. theres now way he could stillï»¿ be alive. If tobi is any other character in naruto and not just another random uchiha he is obito. Because they never said his right side of his head got crushed just his body. (to remind you tobi has screws in the right side of his body) If it did his right half of his brain wouldve been crushed. Which means he wouldnt even have been able to talk.
