Bozo is the nickname of an unidentified male individual, likely employed by the Liang-Dortmund Corporation. On August 11, 2558, Bozo supplied Liang-Dortmund resettlers on the human Outer Colony of Meridian with one M12 Warthog, three M290 Mongeese, and five D79-TC Pelicans. All markings on the vehicles that had identified their previous owners were removed.
