Mihajlo and his twin sister, Larisa, were taken away from their parents soon after their birth. Serbian scientists identified them as potential uberhumans and the President had orders that all such children would be raised by the State. They were taken to a State-run orphanage where they grew up segregated from the other children. When they were six, the twins were introduced to Stephen, another uberhuman. The older boy took them under his wing and over time became their big brother: a protector and a guide to the institutions around them.

Mihajlo and Larisa seemed to lack humanity. They rarely showed emotion and when tragedy struck, as it did so often in their presence, they merely watched. The greater the tragedy the less inclined they were to show any kind of interest. When children started breaking in the impoverished playground, Mihajlo simply turned his back and watched the clouds skate across the sky. Larisa developed an interest, though, and when the children's bones started to pop out of their skin, the smallest smile flickered on her face.

When they were old enough, their 'father' President Milosevic ordered that his Serbian Six be activated to fight revolutionary tendencies across Bosnia and other rogue states. Mihajlo found this period to be dreadfully boring. He participated in the ethnic cleansing but had no interest in pursuing it after the war was drawn to a conclusion. Larisa seemed to be the opposite, embracing the wanton destruction even more so than their older brother, Stephen. Mihajlo followed his sister as a matter of course, not really thinking about options.

When Slobodan Milosevic was taken to The Hague for War Crimes, Stephen and the rest of Serbian Six attempted a rescue. Mihajlo agreed, although he never really managed to feel anything for his 'father' except distant acceptance. When Milosevic was found dead in the prison, Serbian Six was left without a leader.

The missing leader role was quickly filled by Stephen, Neko. The others accepted the move. It was, to most of them, the only option available. As the number two, Mihajlo or Dvoje, had no interest in any kind of leadership position. He also lacked the initiative to make a grab for power.

When Stephen called for an attack on all rogue states Mihajlo agreed. If Serbia could not be run by Milosevic then surely it should fall to his special children?

Mihajlo is comfortable in his world where he is supremely powerful and nothing can touch him. He has very little compassion, even for his twin sister. When he looks out from behind his seemingly-fragile spectacles he sees a world of animated corpses. He can manipulate the world without having to touch it and does so also with obsessive verve. Rarely does he allow his skin to come into contact with anything.

"I suppose the best course of action is to follow the lead of Neko. So far he hasn't managed to get us killed and that must be counted as a positive sign."

Dvoje is a powerful telekinetic like his sister, although his powers are physical rather than mental. He is able to manipulate physical and liquid objects and produce devastating force blasts and protective force shields. On his own he is quite the adversary but as artillery support and occasional cover, Dvoje makes the Serbian Six a very dangerous and destructive adversary.

Since the death of Milosevic, the Serbian Six have refused to wear uniforms. Instead, Mihajlo wears whatever is comfortable. He has no concern about being touched or sullied by anyone since his telekinesis prevents almost any form of contact. He has straight silver-white hair, bright blue eyes and wire-framed spectacles.
