Prussia

Overview... the older brother of Germany. Prussia technically hasn't existed since 1947, but don't tell that to the former Teutonic Knight. But despite the dissolution of his state, Prussia hangs on – mooching off his younger brother Germany, reading comics, and generally pestering both former foes and friends alike.  

Personality... egotistical, warmongering, and completely lacking in social graces. It isn't exactly his fault, though. Unlike certain pansy states (like Austria), Prussia was too busy learning to fight to memorize the names of 50 different types of forks.  But while military training may have taught Prussia martial valor and discipline, it's done nothing to change his weakness for baby animals, his love for his younger brother, or a massively inflated ego.
