Super Sentai overview

The Super Sentai Series (スーパー戦隊シリーズSūpā Sentai Shirīzu? ) is the name given to the long running Japanese superhero team genre of shows produced by Toei Co., Ltd., Toei Agency and Bandai, and aired by TV Asahi ("Super" refers to their use of mecha, and "sentai" is the Japanese word for "task force" or, literally, "fighting squadron" and was also a term used for Japanese squadrons in World War II). The shows are of the tokusatsu genre, featuring live action characters and colorful special effects, and are aimed mainly at children. This series is one of the most prominent tokusatsu productions in Japan, alongside the Ultra Series, the Kamen Rider Series, and the Metal Hero Series, and is adapted in the United States as Power Rangers.

Series overview

The basic premise of the series is that a group of five (in some cases fewer) people gain special powers (magical or technological), wear colored outfits, and use advanced weapons and martial arts skills to battle powerful beings from other planets and/or dimensions threatening to take over the Earth. In most of the episodes, after the team has beaten an army of evil creatures ("grunts") and the "monster of the week", they call for huge robotic vehicles/animals ("mechas") that can combine to form one giant robot to fight an enlarged version of the monster. Sentai series with the giant robot element are specifically known as Super Sentai. While each Sentai series is set in its own reality, a number of TV and video specials feature a teaming up with previous Sentai. The evolution of the Super Sentai Series from its roots in Shotaro Ishinomori's Himitsu Sentai Goranger. The first Sentai series, Himitsu Sentai Goranger, was created by the late Shotaro Ishinomori, creator of Kamen Rider and Cyborg 009 in 1975. He did not create any further Sentai series after his second, J.A.K.Q. Dengekitai, was not received well. These two series were not a part of the Super Sentai series until 1994 when Toei decided to include them with the series that followed.

Following J.A.K.Q., Toei chose to work with Marvel Comics to produce the live action adaptation of Spider-Man (1978), which included the first giant robot in a Toei Superhero show. This concept was used in Toei and Marvel's project Battle Fever J (1979) and was deemed the first Super Sentai Series. The following production of Denshi Sentai Denziman was the first production solely by Toei and written by "Saburo Yatsude".

The term sentai is also occasionally used to describe shows with similar premises, such as Voltron, or even the magical girl team in Sailor Moon, as Naoko Takeuchi deliberately used Sentai ideas. In 2003, Sailor Moon was retold in a fashion somewhat similar to Sentai shows in the form of Pretty Guardian Sailor Moon. While not officially Sentai, some fans of the genre have accepted it as such.
