I’m leaning on it being Drake since it’s been a couple of days since we last saw him, and we know Zoans can recovery pretty well with some time—so at this point, he should have recovered.
I could see him speaking in the ‘formal’ tone, and though Drake’s Den Den has spiky hair, it could simply be laid flat (if it takes on the speaker’s characteristics) seeing as the “hair” seems to be laying flat (unless it’s not hair).
CP0 also failed to put him down, and he knows about their dealings with Wano (specifically Orochi), so him hiding out makes sense as they should be gunning him to clean up their mess.
Though only thing is unless Drake has had his own awakening, I’m not sure he’ll be able to hold off Lucci (who’s the real powerhouse there).
