He has a well-armed air force and navy, complete with battleships (referred to as "gunships"). This is mainly to protect his shipping and business interests worldwide. However, despite his ruthless and self-interested behavior, Khan is willing to act nobly at times, such as ordering his forces into the air to protect Cape Suzette from air pirate attacks. He is also shown to respect Baloo's piloting skills, most notably in the episode "From Here to Machinery", in which Khan's plane had been ambushed by Don Karnage's air pirates and the robotic pilot (created by the sleazy Professor Martin Torque) refused to deviate from its flight plan due to its programming, causing an arriving Baloo to forcibly remove the robot and take control of the plane (with Khan's permission) in order to engage in his usual dogfight with the pirates, resulting in the reinstatement of his laid off pilots.  He also refers to Baloo as "a pilot to be reckoned with" in Plunder & Lightning after Baloo manages to destroy Don Karnage's lightning gun and severely damage the Iron Vulture.
Garth's time-travelling adventures lasted for over 50 years and covered 165 stories (plus two additional stories published in the Daily Mirror Book for Boys , 1970–71). In the backstory, Garth washed ashore in Shetland and was adopted by an elderly couple.  Garth developed almost superhuman strength and eventually became a naval captain and all-round military genius.  Garth travelled through many eras and confronted villains such as Madame Voss and Apollo. His true love was the ancient goddess-like figure, Astra. Garth's sidekick and mentor was Professor Lumiere, who psychoanalyzed the hero and recovered memories of his previous experiences.
