What hetalia - axis powers character do you think is the manliest?

Poland
Because only a real man can crossdress and look so fabulous~

Turkey.
Turkey is the Manliest character, He has facial and body hair Unlike others. Turkey Used to be the one of the strongest countires and still Is. He's positive and manages to stay happy even though his past was Painful for him. He tries to be friendly with everyone and stays polite. Plus his tanned skin makes him unique, as the most countries have pale skin.
And I have no idea why he's so underrated, He's so Manly and Sexy. And in one of the episodes, Germany and Italy admitted his strength por saying:
Germany: "He's stronger than I thought"
Italy:"Turkey is the strongest!"
This was a "irl" reference as Turkey is #16 in most strongest countries. He loves tourist and strangers.
He deserves attention, Even though there were almost no scenes with him in the series, He showed himself as one of the manliest and masculine characters.

Manly is another way of saying "Germany", vice versa.

Italy best

I don't know... I'd say Germania or maybe Hesse... Or it could be Germany.
