The planet is depicted as being inhabited by different cultures, and having a varied ecosystem.[5] The technology of these cultures varies from groups at a Stone Age level, to highly technologically advanced peoples.[4] At the beginning of the comic strip, almost all of these cultures are shown as being under the domination of the tyrant Ming. In all the versions of the Flash Gordon story, Flash Gordon is shown as unifying the peoples of Mongo against Ming, and eventually removing him from power.[3] Later stories often depict Mongo under the rule of its rightful leader, Prince Barin.[3]
