Kyodai Hero

Kyodai Heroes (巨大ヒーロー) is the subgenre of Japanese tokusatsu superhero TV shows that feature giant-sized superheroes similar in many ways to Ultraman.

Examples of these are:

* Tetsujin 28-go
* Ambassador Magma
* Ultraman
* Spectreman
* Mirrorman
* Fireman
* Jumborg Ace
* Meteor Man Zone
* Megaloman
* Denkou Choujin Gridman
* Ike! Godman
* Ike! Greenman

The Kyodai Heroes were made popular mostly by the success of Ultraman and the Ultra Series, which many of these heroes have imitated. These shows were produced by various companies including P-Productions (Ambassador Magma, Spectreman), Tsuburaya Productions (the Ultras, Mirrorman, Fireman, Jumborg Ace), Nippon Gendai/Senkosha (Silver Mask, Iron King) and Toho (Meteor Man Zone, Megaloman, Godman, Greenman).

They have apparently fallen in popularity in mainstream Japan, as there haven't been any new TV shows for many years other than new Ultraman shows. But currently, there are still giant superhero series produced by independent companies in Japan, most notably "", created by veteran suitmation actor/mangaka Ryu Hariken. Bio Planet WoO was one of the more recent kyodai heroes created by Tsuburaya, based on an unused concept created by Eiji Tsuburaya as a continuation of Ultra Q.
