The master of the Earth Cargo Service freighter Fortunate, badly wounded in a Nausicaan pirate attack, whose incapacity leaves his first officer Matthew Ryan free to pursue revenge.
Captain Keene appears in the Enterprise episode Fortunate Son, set in 2151. He commands the Fortunate, a Y-class freighter crewed largely by families who have spent their lives in deep space.
When Nausicaan pirates attack the ship, Keene is seriously injured. Enterprise, sent by Starfleet to answer the distress call, finds him unconscious and the first officer, Ryan, in command and secretly holding a Nausicaan prisoner.
Phlox treats Keene while Ryan takes the freighter after the raiders. Once he recovers, Keene talks with Jonathan Archer about how faster Starfleet ships will change the boomers' way of life, and admits Ryan must answer for his actions.
