Biography
He is a scientist who works for the government. He and his team of scientists created Sil with the help of an alien-DNA sequence they got from outer space through SETI (transmissions from earth to outer space and reverse). After creating her they kept her in confinement for further observation. He saw, how Sil grew up in an extreme way. She already was a child after three months.

Then, when they realised that something sinister was in her body while she was sleeping, he executed the decision of the government to kill her with gas as a form of prevention and run more research regarding this unforeseen, sinister event. However, she fled by breaking out of the confinement and then by fleeing from the place. After that, at the behest of the goverment, he recruited a team of scientists and a killer to search for her and kill her. Under his leadership they follow her trail to the city of Los Angeles. There they hunted her down, but she faked her death. When they found out she was alive, they continued with the hunt.

He was killed by Sil during the decisive hunt, in which she was killed.
