Steven Jacobs is the head of the biotech company, Gen-Sys Laboratories, in San Francisco, which is creating the ALZ-112, an artificial retrovirus cure for Alzheimer's Disease. He has dark eyes and dark hair. He is narcisstic, arrogant, greedy, ambitious, and selfish, often caring about no one but himself. He callously experiments on apes for money, as money is the thing he desires the most. However, he is a pathetic coward deep down. He mostly wears suits, as a head of a company.
