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 2004 Super Sentai Japanese TV 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. it joined Kamen Rider Blade part of Super Hero Time. The footage from the show was used to create the American series Power Rangers S.P.D..
Following its end, a Korean dub of Dekaranger also entitled Template:Hangukeo was broadcast in South Korea in 2005. While both Super Sentai and Power Rangers series had been irregularly broadcast prior, this began a consistent run of Korean dubbed Super Sentai series under the Power Rangers brand following the conclusion of their original Japanese broadcast.
"S.P.D.. Special Police Dekaranger. Five detectives who fight cool with burning hearts. Their mission: To combat space criminals who invaded Earth. They will protect the peace and safety of all humanity!"
The universe has come together where aliens from many different planets coincide in peace. Banban Akaza was transferred to the Earth branch of S.P.D. (Special Police Dekaranger) in the city of Megalopolis by his commander. By that time, a major outbreak of crimes had broken out by a group of aliens known as the Alienizers. Agent Abrella, an Alienizer arms dealer, turns his destructive attention to Earth by helping the criminals there. It's up to the Dekarangers to stop them and bring them to justice.
Dekaranger is the only Super Sentai series in which the gender ratio is equal; out of the total ten Dekarangers, five are male and five are female.
This series is notable in that there is no central villain or evil organization at work throughout this series (although Rainian Agent Abrella serves as a recurring antagonist).
Dekaranger is credited in the ending credits of Power Rangers S.P.D. as "Deka Rangers" where S.P.D. is adapted from.
This is the first series that villains are defeated after only one battle. Villains can be defeated when they are in normal size same as before Hikari Sentai Maskman or using machine (different from other sentai, villains are defeated in normal size then transform to giants or using machine and finally are defeated totally. Total 2 battles)
The opening sequence is different with every episode, with one shot displaying the villain(s) for that particular installment.
The first in the series to feature a Pink Ranger and a Green Ranger on the main team since Mirai Sentai Timeranger.
This is also the first series since Timeranger to have the original Red-Blue-Green-Yellow-Pink main team formation.
Part of this season's title, Deka, means "ten". This season also features 10 Rangers.
"Deka" is also the Japanese slang term for "detective".
Dekaranger has several homages to Metal Heroes. The "Tokusou" in the name, the narrator who repeats the same description every single episode (and was once self-parodied within the show), and a birdman in charge of the organization are all references to Metal Heroes, especially to that of the Space Sheriff Trilogy.
The Dino Thunder special Dino Thunder the Lost Episode shows several shots of Dekaranger footage not used in the US, and at one point you can see the faces of 4 of the Dekarangers as they transform.
Pop idol Shoko Nakagawa had a guest starring role in Episode 38.
Dekaranger is the first Super Sentai series (and the third Tokusatsu overall, after Ultraman Tiga in 1996 and Kamen Rider Kuuga in 2000) to win the Media prize Seiun Award, which is given to the best science-fiction work of either the movies or television for the year.
Dekaranger is the second Sentai series since Fiveman where the female Ranger's uniforms do not have skirts.
Dekaranger was originally going to be named "Sirenger".
The Dekarangers are currently the only Sentai in which every Ranger is called by a nickname.
Similar to Denziman, the Dekaranger gain their powers from an alien source with many of the members recruited by a dog; likewise said dog, Denzi Dog IC, was a robot akin to assisting teammate K-9 Murphy.
Akin to Bioman, likewise the Dekaranger are recruited and assist in powers that are alien in nature. However, this series also has concepts such as the heroes having numerical designations in combat (with only Green and Blue switched between Bioman (where Green is "2" and Blue is "3") and Dekaranger (Blue is "2", Green is "3") as well as the main villains mostly relying on giant robots to fight the main mecha of the allies.
There is also a slight similarity in concept with Gekisou Sentai Carranger's Signalman, who likewise is a policeman from space akin to the universal police organization the Dekaranger are depicted in this series.
Dekaranger is the last Super Sentai season to share a head writer with its immediate predecessor. While the earliest seasons of the franchise would have a head writer shared between several seasons in a row, every season since this one has had a different head writer with no less than a year break between seasons that share a head writer.
