Jack Wynand

Jack is the protagonist of BioShock. He is a young man who, prior to his unwilling arrival in Rapture, was a passenger on an airplane that crashed near the lighthouse that provided entry to the underwater city. During his journey through Rapture, Jack comes across a number of gene-altering substances, known as Plasmids, that he uses to empower and protect himself. According to the passport he used to board the plane, his full name is Jack Wynand and he is twenty-four years old.
Jack is the illegitimate son of Andrew Ryan and Jasmine Jolene, Ryan's lover. While pregnant, Jolene suffered some financial difficulties and decided to sell Jack, as an embryo, to Dr. Brigid Tenenbaum on behalf of Frank Fontaine, without consulting Ryan. Jack was to be Fontaine's back-up plan if he was ever forced into an unfavorable situation by Ryan, which happened during Rapture's Civil War.
Jack was "born" and "grown" by the scientists of Fontaine Futuristics, including Dr. Yi Suchong and Brigid Tenenbaum. According to Audio Diaries by Dr. Yi Suchong, who was responsible for Jack's development, Jack, by the age of one, weighed fifty-eight pounds and had the "gross musculature of a fit nineteen-year-old", thanks to Lot 111. Dr. Suchong also reveals in another Audio Diary that he was responsible for the mind control imprinting that Frank Fontaine requested.
