Dr. Serena Kogan

"For many years humans have believed in what they wanted to believe, but what they believed in was a bit too big for us to grant their wish, Cyberdyne couldn't let them push their limits, their dreams were too much"

About
Dr. Serena Kogan was a geneticist and chief operating biological officer at Cyberdyne Systems. She was born in 1960 and had been working for Cyberdyne for 10 years before her death in 2004. In 2003, Serena persuaded Marcus Wright into signing a contract for Cyberdyne Systems to allow her to do 'research' on Marcus' dead body. She died of her terminal cancer in 2004, just sometime after Cyberdyne had been purchased by the Airforce. Despite Cyberdyne being shut down, her research was continued by Skynet. She created Marcus for a reason, to survive Judgement Day and to harvest humans to bring back to Skynet.

Personality
Serena's personality at the begining of the film was all 'nice and friendly' but the inside of her was selfish and greedy all along, she just wanted to experiment on a human to see the future of the machines. Later on, Skynet takes her appearance saying that Serena programmed Marcus Wright but he executed that programming 'beautifuly'.
