@uniaka:
Roger doesn't look like he had more then two pirate rivals close to his level, WB and Shiki, one of them defeated by him. The one that was his main rival, guy who killed him many times wasn't even a pirate, it was Garp, so I don't expect 11 pirates close in power to Luffy, that would be too much of a change from 4 yonkous who are up there( world's strongest people) to 11 world's strongest people.
And monster group is power based, we don't know if the 11 supernovas groups is power based, you said it's bounty based.
there to 11 guys.
Roger has nothing to do with the amount of rivals Luffy will have. This is Luffy's story.
And we have literally no reason to believe that the Worst Generation is not power-based. They're the guys who have been the center of attention in the New World, being even grouped with the likes of Teach.
@Razh:
I really think Sanji could beat some of those guys. Don't care what they're "supposed to represent".
Urouge is a physical fighter so Sanji could have a decent chance. Capone too if he can get through his army. Bonney has a nasty devil fruit, so probably no. Not without some seastone maybe. I could see him doing against Killer and Apoo decently, maybe even Drake and Hawkins. Kid and Law are the tricky ones, since they seem to be a little above rest. But I could see Sanji providing a good fight. Their fighting capabilities shouldn't be too far apart. They all have devil fruits abilities, but effectively, so does Sanji.
Hopefully he'll get to show some heavy hitters soon.
We literally know almost nothing about most of the Worst Generation's abilities and you already go saying "Oh, Sanji could beat this guy because physical fighting and such". This is some Naruto Forums logic.
You don't define those things with potential match ups. If Oda wanted, he could make Urouge curbstomp Sanji for all we know (let's hope he doesn't even think about it) because he literally doesn't care about power levels or any other detail like that. This is the guy who makes his villain characters stronger because people don't think they are strong enough.
Those are they guys Oda designed to be the future of piracy and new top guys.
