In every Sentai show, the fight between good and evil is illustrated, with the good side winning most of the time. The basic premise of the series is that a group of five people gain special powers, 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 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.
The first Sentai series, Himitsu Sentai Goranger, was created by the late Shotaro Ishinomori, creator of Kamen Rider and Cyborg 009 in 1975. He left the project after the second series: JAKQ Dengekitai.
The third Sentai series, Battle Fever J (1979), is the first Super Sentai show (on account of it being the first to have a giant robot that the heroes ride - The past two shows only had vehicles). Many others appeared afterwards, including 1992's Kyouryuu Sentai Zyuranger, which was later Americanized to become the first season of Power Rangers (Mighty Morphin Power Rangers), followed by sequels based on new Sentai shows. However, Sentai shows are for a more mature audience than Power Rangers, as evidenced by deeper character development and slightly darker storylines, sometimes bordering on a soap-opera tone.
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. However, this definition never was official for these shows.

- 1980 - Denshi Sentai Denjiman (Electronic Task Force Denjiman) - The first to have a transforming giant robot, and the first to have "ski-goggle" masks (as opposed to "bug-eye" visors with small holes drilled in them, as was the case in the previous four series).
