Hansl Schaefer had been born with glowing yellow eyes and chalk white skin, so his parents knew he was an uber, although apart from the eyes and skin, nothing else seemed to be different from his older siblings. His mother wasn't able to cope with having a child who might turn into a monster or superhero at any time, so she left, and took Hansl's two sisters with her. Hansl and his father were left behind.

As Hansl grew, he found himself drawn to the desolate places where he wasn't looked upon as a freak. He studied Geography, particularly the Arctic region, and gained work with industrialists investigating oil resources. During an expedition, his secondary, more potent, uberhuman abilities surfaced when he was forced to save three researchers caught in an underground fire. He picked up his colleagues and ran so fast that he outpaced the expanding explosion. It was a defining moment, and Hansl realised he had a duty to serve the community rather than hide from it.

At this time, his father remarried and Hansl found himself becoming the step son of the German uber, Golden Bear. She convinced him to join Uber Force and he agreed, although when his step sister, Schmetterling also joined the team, Hansl realised that he was developing an unusual crush on her. He hadn't ever allowed himself to fall in love before, seeing himself as an outcast; but in the company of other ubers he realised that he wasn't so monstrous after all. The only problem was that the love of his life was also his step sister.

Hansl is a caring and bold young man, who does his bit for the team without expecting recognition or applause. He has been that way since childhood, mostly due to his desire to conform and not stand out like a freak. His infatuation with Schmetterling has brought out the jealous and frustrated side of his personality though, and Hansl is not sure how to cope with his conflicting emotions.

"Never saw that mountain until it was too late..."

Zeitgeist is able to run at extremely rapid speeds, easily exceeding 2000kmph, which is twice the speed of sound and quite dangerous to the environment. Being a cautious man, Zeitgeist usually limits his speeds to subsonic levels. When he is moving at uberhuman speeds, Zeitgeist generates a protective field around his body which protects him from most collisions, and he has the tendency to simply run through objects, including walls and the occasional mountain.

Zeitgeist was born with yellow glowing eyes and chalk white skin. As adolescence set in his hair turned green. He has always been looked upon as different, but since joining the U-Force he no longer actively hides his appearance. As Zeitgeist, he wears a dark green uniform with a white stripe down the outside of his legs; yellow shoulder guards, gloves and boots.
