I'm gonna tackle the big list of shadowy figures. Right to left, top to bottom.
Pekoms and Tamago. Easy, everyone knew this.
Unknown, but rather obviously not Hawkins, by this point. The chin shape is wrong, the sword is misplaced and the clothing is wrong. We can't even see the background, or what's held in the hand. I expect this one to be a Yonko subordinate we'll meet relatively soon.
Kid.
Shilliew. The chin shape is right, the lips are right, the nose is right, the cigar is right and his bulk is right. We never saw his hair, so that's not an indicator.
Rob Lucci. Hair is right, hat is right, drink is right, posture is right, and it even looks like the build is right.
Next three are unknown. Due to the details given, it seems likely that they are new characters. Direct your attention at their background though. Very 'dark' feel to it. Barebones, like they are in a warehouse.
Unknown. Appears to be at sea, though. The lantern hanging above him is the sort you'd see in a ship, and the screen for his projector was hastily set up.
Unknown. Not much we can draw from him, except that he's probably on land due to the stone architecture. Without even being able to see his face, the indication might be that he's someone we'll see very soon, to drive up speculation.
These two are unknown. Again, they appear to be on land, and as a wild guess, based on their fashion sense, I'd say they would be members of DoFlamingo's group. Barring that, the background is vaguely like Kid's with a sort of industrial feel to it.
Rob Lucci, again. I know, but look at him. Then look at the background. It's the same place and the same guy. You can even see the curly hair on his shoulder. One problem though, the screens appear to be different.
I'd love for this last one to be Gekko Moria. But the hair is all wrong. Ignore the problems with his sheer bulk and general shape. He could have had surgery performed on him to acquire a new, stronger body. The hair was nearly a trademark, and presumably most of his head would stick around as well.Oh, and I'm willing to bet that in the New World, in addition to the WG bounties, there are something like "Yonkou" bounties, which represent how much one of the Emperors want to kill you. We'll be introduced to the concept before too long, but it would help explain why Hawkins' bounty barely raised. He's been pissing off Yonkou instead of the WG.
the yonkou are not allied so if they had yonkou bountys/rewards for people they want dead then it would be seperate.
