In every Super Sentai series, the protagonists are a team of people who – using either wrist-worn or hand-held devices – transform into superheroes and gain superpowers – color-coded uniforms, signature weapons, sidearms, and fighting skills – to battle a group of otherworldly supervillains that threaten to take over the Earth. In a typical episode, the heroes thwart the enemies' plans and defeat an army of enemy soldiers and the monster of the week before an enlarged version of the monster confronts them, only to be defeated once again when the heroes fight it with their super robot mecha. Each Sentai series is set in its own unique fictional universe; various TV, video, and film specials feature a team-up among two or more teams.

The first two Super Sentai series were created by Shotaro Ishinomori, then known for the 1971–1973 Kamen Rider TV series and the long-running manga Cyborg 009. He developed Himitsu Sentai Gorenger, which ran from 1975 to 1977, and J.A.K.Q. Dengekitai, released in 1977. Toei Company put the franchise on hiatus in 1978, collaborating with Marvel Comics to produce a live-action Spider-Man series, which added giant robots to the concept of tokusatsu shows. The giant robot concept was carried over to Toei and Marvel's next show, Battle Fever J, released in 1979, and was then used throughout the Super Sentai series. The next two series Denshi Sentai Denjiman and Taiyo Sentai Sun Vulcan had Marvel copyrights and co-productions, despite no influence. Subsequently, the remainder of the series has been solely produced by Toei Company.
