Jack Kelso was born on 11 April, 1935/75 BH. In 1953/47 BH, Jack joined the American Army to fight in Outworld against Kahn's Army along with Ira Hogeboom, Courtney Shelton, Chris Majewski and Cole Phelps and to stop Shao Kahn's advantages against the United States of America and the world in general. In 1960/40 BH, Cole Phelps became a police detective for the LAPD, something that intrigued Kelso. In 1976/24 BH, Jack became a police Officer himself and in 22 BH he became a Detective for Elsa Lichtmann, looking into the Lou Buchwalter (originally pronounced as Luu Buh-walter) case in which the SRF, headed by Lenard Monroe, played a villainous part in.
Jack's adventures pit him up against many main players of the Los Angeles crime and economic scene and scheme, like Kurtis Benson, the aforementioned Monroe, Harlan Fontaine and his lapdog, the former brother-in-arms Courtney Shelton, Ray Buttowski and even the police chief, William Worrell.
