in the past he fights Hashirama Senju since he's really Madara Uchiha
Tobi fights against Konan and is victorious in the episode called Breached Mind. This is episode number 213. Tobi fights Naruto and a group of fighters in the Naruto Shippuden episode number 134. The name of the episode is Banquet Invitation.
I'm not sure of when Naruto fights Tobi alone, but there is an episode in Shippuden in which he fights Tobi with a group of six or so shinobi whilst on a quest for Sasuke. This episode is number 134, called "Banquet Invitation".
The eight man squad, Fu and Torune, Konan, Naruto

That's about it for now.
Tobi and Deidara appear at the end of 122 and the fight is from 123 to 124, where Deidara dies..
Just watch 'The Chunin Exams: Final Rounds Begin!' Episodes. You'll find it at the end of those.
I am positive it is Tobi
Tobi because nobody could defeat him. But i think if naruto fight Tobi Tobi will get kill
Tobi :D
Madara is not Tobi.
No it is not. If you are referring to the episode where Tobi was with Didara in the dango shop when he said "Ichibi, Nibi, Tobi!" then no it was just Tobi being stupid.
Sasuke sees Tobi when he fights Deidara. Tobi flees after Deidara self-detonates. However, after he kills Itachi, Sasuke meets Tobi, who reveals himself as Madara Uchiha. The Shipuden Episode is 139.
