Tokusou Sentai Dekaranger (特捜戦隊デカレンジャー, Tokusō Sentai Dekarenjā), translated into English as Special Investigation Squadron Dekaranger, was the twenty-eighth production of the Super Sentai television series. Deka is Japanese colloquial slang for "detective" and has no direct translation, but is sometimes written over the kanji for "Keiji" (a more formal term for detective); it is also a Greek prefix "deca", meaning "ten", and a total of ten Dekarangers appear in the series and movie combined. The footage from the show was used to create the American series Power Rangers: S.P.D..
The story begins when Banban Akaza arrives on Earth to the city of Megalopolis. He is transferred to the S.P.D. (Special Police DekaRanger) Earth branch by his commander. By that time, Agent Abrella, an Alienizer arms dealer, turns his destructive attention to Earth, helping the criminals there. It's up to the DekaRangers to stop them and bring them to justice. The SPD of Earth are stationed in the DekaBase under the command of Doggy Kruger.
