[RSJNaruto]

yep with out breaking a sweat

 

[Relostar Devil]

Nope, he won't bcoz arlong will make fun of oda by saying him trolla, which will make him go nuts and will give these mentioned powerups to arlong instead of luffy.

 

[Naruto Power]

this fight would show the advancement of luffy for sure. I think luffy could beat arlong just using his normal power now.
