Well, this is from East Blue
Humour’s pretty generic straight man/funny man (what’s the japanese term, something starting with a t/boke)
Funny man says something earnest and stupid, straight man corrects him.
It’s hardly the peak in wit and humour but it can be found quite often in One Piece. Usually with the boke (most often Usopp) having sharp teeth and shouting.
The special moves joke is fine.
The sensing some tension one is less Luffy. There’s an awareness that he doesn’t have in the manga. Maybe some more western attempted disarm snark. But I simply don’t think a full one to one will come across well anyway.
Course, that could raise the question why bother trying, fair enough. And this may well turn out to be total shit. But I don’t especially think these snippets we‘ve seen quite hit the bar of One Piece has been bastardised and ruined comments just yet.
