nice fanfic..Sasuke, because of the Rinnegan would allow him to transport him through dimensions and he could switch places with Minato's Kunai not to mention he could absorb the Bijuu Chakra as well.
I would say Minato would win. Minato can teleport way more times then sasuke and he has more chakra. Amaterasu is countered by FTG.
nikka stop soking saski tick..especialy after he admited his lost like fodder to naroto..RG Sasuke has the CQC powers to edge this. However I do not say this is a neg diff.
