Minato's, his base rasengan is bigger then the others. size equal powers.Whose Rasengan is the strongest? (simiple one)
- Naruto
- kakashi
- 4th hokage
- jiraiya
- konohamaru
NARUTO PERFECTED IT WITH his element NOT THE BASE ON !!!!:flaw:agreed naruto! minato might have created it but naruto perfected it
What was impressive was when Naruto was concentrating he exploded the ball (2nd part of learning the rasengan) but Minato's base rasengan is bigger then Naruto's or Jiraiya's making it stronger just like how Oodama rasengan is stronger than base rasengan.during the training for naruto to learn it J-man high lighted he was burning his hand with his own chakra density and this was right after the chunin exam. so now i would say based on strength naruto has it in spades. but for ability to use it ftg plus rasengan is insane.
