Switzerland - Vash
Switzerland is seemingly eternally neutral and lives his life as a hermit/recluse, surrounded by the Alps. He maintains his cool air of complete indifference.
Though he appears to be peaceful, he actually is one the biggest producer of guns in the world.
He is also very frugal, for buying cheap cheese rather than a more expensive variety, claiming he likes the taste of it better.
He is cold and unwelcoming, but has a soft spot and cares a lot about people he‘s close with (ie Liechtenstein)
