well i somewhat understand yall's reasoning but not how my top 15 wud go
1. Itachi (i mean he kinda beat the edo in death, defeated nagato once he went back into his prime, and LET sasuke win even when he was ill so yeah)
2. Naruto (defeated multiple bijuu and jinchuriki, is as fast as his dad, and is facin off against arguably one of the strongest ninjas in history along with a few bijuu)
3. Sasuke (EMS obvious and even with just MS was a beast)
4. Madara (EMS, Rinnegan< and insanely powerful fire style justu and crazy good taijutsu)
5. Nagato (rinnegan and rinnegan jutsu)
6. Hashirama (took on madara and nine tails)
7. Minato (took on nine tails and tobi)
8. third raikage (took on 8 tails alone, only ever suffered a self inflicted wound)
9. A (fastest man alive, has bijuu sized chakra volume)
10. Ginkaku and Kinkaku (defeated the 2nd hokage, survived 2 weeks in 9 tails belly)
11. Tobirama ( invented edotensei, skilled in ninjutsu, genjutsu and taijutsu)
12. Kimimaro (if he hadnt been on his deathbed he wouldve been practically impossible to kill he kinda survived buried under thousands of pounds of sand)
13. Gaara (can control sand and is nearly impossible to wound)
14. Bee (in synch with the 8 tails, defeated A with help from gyuuki)
15. Kakashi (MS, chidori, can copy jutsu, and due to sharingan can undo genjutsu and doesnt rely on the MS to fight)
remember this is opinion based and i respect other opinions so respect mine

but criticism is ok just no damn flame wars.
