A.D.F.

Power Rangers: Alien Defence Force, abbreviated to A.D.F. is a Power Rangers series that takes place before and during Super Mario Rangers.

History
The Alien Defence Force serves as a precursor to S.P.D. and functions similarly, with the main difference being that it is set in the present day. The A.D.F.s purpose is to protect the Human race from alien invaders and criminals, while simultaneously keeping the knowledge of aliens hidden from the general public. The A.D.F. is set up in almost every country in the world and has a team of seven operatives in each city. Along with the seven Rangers the teams are assigned an Alpha-8 unit. The series follows unit PG-5321 as they attempt to protect the city of Pine Grove from alien threats. The primary antagonist is Marudas, an Ekurian warlord who wishes to conquer Earth and transform it into a gigantic fortress. The group capture the aliens by beating them, then putting them in suspended animation before storing them in a massive undeground facility underneath Antarctica.
