This is Prussia, the most awesome country that ever was. Though overthrown after WWII, he still makes appearances in some episodes of Hetalia (mostly in World Series).
His little brother is Germany, who he likes to call "West"(a reference to Prussia and Germany's geological location) and his chick's name is Gilbird. He also loves to get in fights and might try to piss you off for just that reason, but don't let it get to you. Though he acts like a dope, he's truly hard working and very diligent (not that he'd let you know that!). Basically, Prussia is the embodiment of all things awesome, sexy, and, for reasons unknown, very lovable.
