The Democratic Order of Planets, or DOOP for short, is a collective organization of planets that gather together to provide a limited sort of shared governance. They were briefly housed in a four hundred billion dollar space station orbiting the Neutral Planet, which was destroyed by Zapp Brannigan during the ceremony to celebrate its completion. Afterwards, they returned to their former, somewhat derelict headquarters in Weehauken, New Jersey.
The DOOP maintains a fleet of ships which, under the direction of Zapp Brannigan, captain of the flagship Nimbus, engage in a variety of humanitarian conquests, as well as occassionally being called in to defend a member planet.
