Minato and Tobi (Obito) fight......

[Sasuke Itachi Uchiha]

Minato ended up dying not to kurama killing him but to betting the future on Naruto. So if you guys want to play the indirect death game then Minato wins when Naruto Wins .

thats true he did die betting the future on naruto

 

[USSJ Future Trunks]

kurama killed him. if obito fought with kurama side by side obito would be credited as winner by everyone. anyway who even could have handled obito besides minato back then?
