The Zip Morgan story in the 1963 Young Marvelman Adventures Annual appears to be part two of a continued story, but does not specify where part one saw print.
Captain Zip Morgan was an officer of the Space Patrol, a military unit who patrolled Earth's Solar System in the future. Apparently based on Mars, Zip and his sidekick Buzzy, aided by allies such as Princess Kara, defended humanity from criminals like Sorl and Rorga, giant alien ants and other menaces in a number of unlikely adventures including tracking the lost treasure ship of Rana to Mercury.
