Easily Luffy. All Naruto did was get a bigger Rasengan. FMI Luffy was already above 6T Naruto.

Luffy for sure

I dont watch naruto so lets just say a god is more powerful than a fox

Lol, that would be the case if the so called god was an actual god and if the fox didn’t have the capability of destroying the world

Usually Naruto characters beat OP characters but in this case Naruto actually loses. He only has access to like 2 tails and his rasengan is slow. Luffy wins mid diff
