Killerbee without sameda
Kakashi without Obito ms
Obito with both sharingan but no senju dna
Nagato without madara rennigan
NOW MAKE YOUR OVERALL TOP TEN WITH EXPLANATION
isnt madara ems a given power???...
here is my list
naruto....he would have sage mode and a larger chakra pool, since he isnt using chakra for the seal....also he would have some ninja techniques and would have much improved chakra control.....also he could fuse with ma and pa
killer bee...tied with naruto...neither wins in a fight...both are my number 1 for this list...maybe kb has a slight edge...so naruto and bee are very close.
kakashi....he has been underrated...he has speed of sasuke better smell than kiba, and is said to be as smart as shikamaru. and was a young jonin like itachi...if he had more chakra he would be so op....without sharingan he wouldve learned more raiton techs...and a second element...he is my number 3 guy
nagato is my number 4 since he has large chakra pool and wouldve learned his nature style.....
danzo is number 5/6 and kabuto is number 5/6...they tie
number 7-10 are madara sasuke and obito...
obito without senju dna and with both sharingan would be a halfcrushed ninja, and couldnt move anywhere let alone fight....madara and sasuke would be blind due to ms overuse...(and if obito had ms he might be blind as well)
(i dont wanna make a top ten so i just organized the people who have "given power"....this is going under the assumption that events progressed like normal....
