It's his face, mostly. They both have that long, lewd face. I suppose Mayuri has it, too, but I don't feel it's as prominent.
Didn't Law say something about them being part of an old government experiment to engineer giant soldiers?
Also, Law has no idea what he got himself into by allying with Luffy. 😂
I understand. For me, though, it's quite literally he looks like Orochimaru. He's got that slime factor about him, which is I think what sets the two apart from Mayuri. He's creepy, but I don't consider him slimy.
What if the worst generation just all joined forces? That'd be kinda crazy.
I'm more interested in which emperor they're gonna be going after. I would assume it's the fat lady, since Luffy already has beef with her. No pun intended.
Mayuri isn't slimey. He's just cold.
I don't think Blackbeard would join forces with Luffy. I can't wait until we get to the final war for One Piece.
Big Mom would give Kidd more incentive to join. He has been giving her trouble and it would be cool to see him join forces with the others to take her down. But I know I was thinking Shanks at first. Still am somewhat.

Usopp is such a lucky bastard. >_>
My theory regarding that fruit is that Caesar engineered a regular fruit to react to a devil fruit user (the Slime), so he can ingest it and make himself explode (remember the legend about eating two fruits and exploding as a result?). Those fake fruits don't actually give you powers, they only react over the power of a devil fruit user. That would be my theory anyways.
