My idea is similar to Hetalia or Countryballs- I draw personifications of different countries. The idea came up a year ago, but I was late with its realization. All of them will be militant and warrior-like, with dirt and blood. Not because of some political persuasion, but simply because that what I always draw in any case, and the idea of warrior-countries gives a lot of creative freedom. And a some politics is always fun, from time to time.
Every character is going to have some stereotypical attributes, that I am going to use in one way or another.
He still is a Teutonic knight, and a big one at that ( if you can see a knight in this concept, of course). And high-tech. Extremely.
Germany is considered to be clean, orderly and modern, so he wears a mechsuit. Something like an Ironman suit, but with more precision German engineering in it. And more stylish. Unlike earlier times, he mostly fights long ranged battles now, to keep the suit clean.
Has unfoldable wings and thrusters on his back, like any proper mecha should.
