Now this is a poll.
Yes. I approve this poll tremendously.
My vote went to Crocodile (or course). Handsome, stylish, arrogant, highly intelligent, and utterly unapologetic in his evil, what's not to love? And he's the original One Piece pimp. The fact that he tormented Vivi is just a bonus (I'm sorry, MetaMario). XD
Other than him, I like Doflamingo for his extravagance, his casual confidence, and his constant amusement at absolutely everything. And being a slaver, he's also probably kinky. XD Lucci and Mihawk would be my next choices, but more for aesthetic reasons, rather than personality. As for those not listed, I would add Enel because his chiseled shirtlessness and deluded god-complex are a fabulous combination. And of course, Zoro (because he's Zoro).
Ace was probably the most conventionally handsome character in the series, especially his design later on. Although he's not really my type, I think he does deserve to be on this poll, even posthumously.
Although Doflamingo IS awesome. Voting for him feels like a vote for DoflaCroc which I'd rather not too.
That's just because DxC is the most popular Doflamingo pairing at the moment; before that, all we pretty much saw was DoflaKuma and (rarely) Dofla/Bellamy (and/or Sarquiss). Oh, and Dofla/Tsuru. shudder
Once Doflamingo's character is explored more thoroughly later on in the series (and he finally gets a chance to interact with more characters, especially female ones), we'll have more pairings to choose from. Don't forget that he, too, is a pimp.
Besides, a vote for Doflamingo is quite possibly a vote for The Master. XD
As for omitting the Strawhats from this poll, it's not really that much of a big deal to me. Listing all seven male Strawhats (including Chopper) would only leave room for two more guys plus "Other." The crew will always be the most popular choices, so I don't really see anything wrong with giving some 'lesser' characters a chance to shine. And like the old poll, if you don't see your pick listed here, just post who you'd prefer. It is a forum.
Besides, if you are unable to list every single male character in One Piece due to the poll's 10-choice limit, it could never be considered an "accurate" poll, anyway. Because you know that someone, somewhere, thinks Blackbeard is just the hottest thing ever. XD
Now, all we need is for someone to update the Hottest Girl poll and make sure Sadi-chan is on it. Then all will be right with the world.
