Ultraseven (ウルトラセブン, Urutora Sebun) is a Japanese tokusatsu science fiction television series created by Eiji Tsuburaya.

To combat them, the Terrestrial Defense Force establishes the Ultra Garrison, a team of six elite members who utilize high-tech vehicles and weaponry.

[3] TBS eventually settled on a fusion of Eiji's and Otomo's ideas and Eiji submitted a treatment titled The Ultra Garrison, which featured six trained astronauts (including an android named "John") stationed on a satellite called "Mother", the first line of defense against alien invaders.

Many of the actors hired were chosen from Toho's acting pool, since the studio was one of the financial investors for Tsuburaya Productions.

The issue was featured on an article of the Asahi Shimbun newspaper, which sparked public outrage and forced Tsuburaya Productions to change the name to "Kyuketsu Seijin" (Vampire Alien).

[17] In 1985, Turner Program Services licensed the series in a 15-year contract from Tsuburaya Productions, who provided the English dubbed versions produced in Honolulu by Tsuburaya-Hawaii, Inc. in the mid-1970s.

Finding this English version to be lacking, Turner commissioned the Canadian children's programming production house, Cinar, to dub all 49 episodes for run in syndication.

Unsatisfied with Cinar's resultant work, Turner put the series into their vaults until 1994, when they were alerted that the episodes were never broadcast.

When the contract expired in 2001, Turner returned all the materials (film elements, videotapes, audio masters) to Tsuburaya Productions.

Factory announced to have struck a multi-year deal with Alliance Entertainment and Mill Creek Entertainment, with the blessings of Tsuburaya and Indigo, that granted them the exclusive SVOD and AVOD digital rights to the Ultra series and films (1,100 episodes and 20 films) acquired by Mill Creek the previous year.

[25] Pokémon creator Satoshi Tajiri said that the Poké Ball concept was inspired by Ultraseven's Capsule Monsters.
