Obito is dead reinaldo (Tobi could or could not be Obito/Madara). now the strongest person in Naruto is Pain with his Rinnegan as it is the precussor to sharingan and byakugan. Pain took down the frog sannin (legendary ninja) and leader of the mist country hidden village (a ninja who beat the sannin when they were at their most powerful by himself). Compare to Pain, Tobi is an insect who just buzzed around.
