Yah whenever Naruto is in a sticky situation, Rasengan!… of course now we have the variations... which are slightly better but still bland.
Nevertheless, I hope Luffy can actuallly maintain haki in terms of real combat so he can be more on par with logia. I mean he did "somewhat" grab? or hit Crocodile from stopping and his arm did not turn into sand. But who knows, it could just be lucky.
Anyways, I am sure after this incident + the whole IMpel down breaking incident, Luffy will be getting the most credit. Even though Buggy's fame will rise, Luffy will skyrocket. I mean seriously, this is basically on par with what the Revolutions are doing right? But they are attacking the world government direclty instead of the Marines. As far as we know, no one has been this much attacking the Marine as Luffy has. I mean he is noticable for several things:
1. Defeating Shichibukai
2. Direclty toppling World Government Enies Lobby
3. Infiltrating and breaking out prisiniors from Impel Down
4. And now intervening with the biggest war in ages.
I mean even other pirates with high bounties have never been shown to defy the world's power in this method. If they have, they without a doubt they would have been mentioned and Luffy's act would be less "glorified". I mean hell, if Fisher TIger received that much fame for breaking out of Impel Down, then Luffy's arsenal of feats should make him even more legendary.
