Jetty was one of several crew members under Robert Blake aboard the UESC Marathon who successfully detected an open transporter coil aboard an attacking Pfhor ship. A unit of fusion gun-packing Bobs - Fusion Unit Alpha - was sent in response to locate and disable the device pinning down the Marathon's engines. As he was mentioned by name only in Marathon Infinity, Jetty may or may not have been aboard the Marathon in the main timeline explored in Marathon and Marathon 2: Durandal.
