1 Rikudo Sennin ... I think this one doesn't need explanation...
2 Obito Uchiha ... since he's the Juubi's jinchuuriki, and it's not like he can be easily defeated
3 it would be Hashirama if Madara hadn't taken his cells and hadn't awakened the Rinnegan lol
4 Hashirama ... he was the strongest shinobi of his era, the one who defeated Madara, if Madara had no Rinnegan Hashirama would be the 3rd
5 Tobirama, he's always calm and invented a load of jutsus, he's very cool imo...
5 Itachi Uchiha he's not just another Uchiha who possesses the Mangekyou Sharingan but he's also very intelligent so he can beat people who're stronger than him
6 Uzumaki Naruto... even though he's the main character so one day he will be the strongest he isn't the strongest yet Lol
7 Uchiha Sasuke ... hasn't shown much ... he's still weaker than Naruto
8 the 5 kage ... Raikage, Tsunade, Mizukage, Gaara, and the Tsuchikage...
