Assuming Captain was never captured by Millennium, or perhaps in an AU where he has the chance for his personality to flourish, how do you picture him being like? what is the /true/ human Hans like?
See, I think this is a highly interesting concept because it entirely depends on the background you give him. Since there is little to no information about him, I let my imagination run wild. I did however use ‘Desert Guardian’ as a guideline for my AU idea of a Hans Günsche, that has never become part of Millennium.
Let’s start out with my basic BIO for him. Hans being born in Germany on a small farm with his parents. He’s a born werewolf due to his father being one. Naturally this comes with the family keeping this as a secret and here comes the twist - it remains a secret. Shifting the timeline in a way that during WW2 Hans would be old enough to enroll in the army to be send to North Africa to join the Africa Korps. Hans Günsche is a 25+ year old soldier with blonde hair, stationed somewhere far away from Europe in order to support a tank division in the desert. He’s not convinced that this war is just and applied to be send to Africa instead of fighting in the front lines for something he thinks is unjust. Deserting his post is not an option however, because that would only get him and his parents at home killed or exposed.
So being at the Afrikakorps is the best possible solution in getting through the war, where he might end up making friends but most likely more enemies. The moment he stops being a soldier, is the moment he kills some of his fellow soldiers who tried to rape a native woman while throwing racist slurs at her. That act disgusted him so much that he faked his own death and deserted to return to Germany. His parents are dead by the time he returns and the war almost over. Hans becomes a Mercenary with a strong set of morals. He works as a bodyguard to protect innocent people, takes contract kills for those who deserve it and never once raises his weapon in intolerance towards other cultures.
He’s actually quite fascinated by them. During his time in Africa he learned a lot and travels the world only to end up settling down in England when he’s reached a certain age. His blonde hair white by then, but he remains the rugged soldier from all those years ago, carrying his secret with him. Hans is a kind soul, polite, quiet and someone who avoids unnecessary fighting.
What made him settle down in England however, are the vampire sightings. Because the beast within him, won’t let him ignore that specific threat which ultimately leads to him approaching Hellsing.
