Overview... despite being a relatively young nation, Germany acts like one much older. He does have a lot of weight on his shoulders, after all. Not only did the result of the last war leave his economy devastated, but now he's engaged in another war (basically started by his boss) and stuck with two barely trained allies for help. It's enough to make anyone age quickly, to say nothing of the complete madman his current boss has turned out to be.
Personality... stern, disciplined, and completely hopeless at emotions. Tall, muscular, and gruff, Germany can come off as the worst brand of drill sergeant. But he does care about his allies, and his harshness in training is only an extension of his worry for them. And with allies like Italy, it's really hard not to worry.
