Larisa was taken from her mother within a few weeks of her birth so she has no memory of the woman, however, she has been plagued by vivid dreams ever since can remember. In these dreams she can see her mother, but her mother is horrible and twisted. Larisa is tortured in these dreams and torn apart by various insidious devices. She has long since stopped waking from these dreams screaming at the top of her lungs. She has accepted them as she has accepted everything else about her life.

Larisa and her twin brother Mihajlo were raised in a State-run orphanage specifically tailored to train young uberhumans. The twins were both able to manipulate the world around them simply through thought. Larisa tended to act out her insidious dreams and had to be chastised repeatedly for hurting the other children. She ignored the punishments and thought of new ways to break the other seemingly happy children.

When she was six she was introduced to her big brother, Stephen. She was initially unimpressed, but the longer she stayed in his charge the more she began to see a kindred spirit in him. His anger was delicious and her burgeoning telepathic abilities were drawn to him. She drifted from her brother to Stephen in a natural progression, and when the group of uberhuman 'orphans' were christened the Serbian Six she was at the forefront of their clandestine activities.

The Serbian Six were sent out to bring vengeance upon those dissidents who sought to break from Serbia. She thrilled in the bloody massacres, the ethnic cleansing. She was still a teenager but her bloodlust put even the most hardened soldier to shame. Of all the Serbian Six, it was Larisa who threw herself into the slaughter with the most abandon.

Milosevic thought she was devoted to him, but the slaughter and the torture were solely for her own pleasure. When she killed she thought of no one else. Stephen was a fragment of her past, Milosvic a pale ghost, her brother a distant hum.

But then the party stopped and Larisa was forcibly reeled in. Milosevic was taken to the Hague for crimes against humanity and the Serbian Six were wanted criminals. Her world had seemingly turned upside down and it was then that she turned to Stephen. He cradled her at night time and for a while she regressed to childhood. But then Stephen had an idea. They would storm the prison in the Hague and free their 'father'. At the thought of future mayhem, Larisa brightened. The Serbian Six were inspired. The Hague stood no chance at all.

Larisa discovered that even the best laid plans sometimes find themselves without a completely satisfying resolution. Their 'father' was dead, plagued by a heart attack, and their attack had been at least momentarily deflected by super heroes. But Stephen rallied the Six again and he boldly commanded them to take Serbia by force.

Larisa felt alive at the thought of ruling a country. She has planned her realm out to the last torture chamber, and is just waiting for the Serbian Six to topple the government and establish their rule.

Larisa is unhinged. She has been a sociopath since childhood and there seems to be no salvation for her in any immediate future. She was raised to be a weapon and that is what she has become: completely lethal and without remorse or pity. She will just as likely rip the skin off a little child as she would to pierce the heart of a hardened soldier with a fence post. As long as she is causing damage she is happy.

She looks to Stephen for guidance when things go haywire, and he has proven to be a direct and bold leader.

"So many ways to peel the heads off soldiers... and so little time!"

Sestorica is a powerful telekinetic whose powers are solely generated through her mind. She is able to manipulate the world around her and create force fields and levitate from the ground. As well as these psychokinetic abilities, Larisa is also a powerful telepath. She is able to create a mental link between her team mates which allows them to communicate through thought alone. She is also able to search crowds for minds as well as deliver stunning psionic charges and read minds.

Larisa has very pale skin, blue eyes and a shock of white hair which tends to billow about her body as a result of her psychokinetic powers. She is chillingly beautiful but even her friends find her unsettling to be around.
