Gridman Sigma

is the younger brother of Gridman in a novel sequel series, Gridman the Hyper Agent: The Demon King's Counterattack. Sigma would have become the alter ego of Takeshi Todo, a reformed antagonist of the original series.
In 2015, Gridman Sigma made his first public appearance at the end of the anime short, Gridman the Hyper Agent: boys invent great hero.
==Conception==
Girdman Sigma was created both for the serial novel and Kazumitsu Akamatsu's desire to have both Thunder and King Gridman to fight side-by-side, hence his later form as King Gridman Sigma.
This plan was formulated back during the production of the original show. In the third quarter of the series, Takeshi Todo was meant to steal Gridman's data and become , a rival character and Kahn Digifer's servant, before redeeming himself as . Additionally, had the original plan taken place without the aforementioned production problems, Grid Knight would star in a sequel season. As revealed in an old magazine called , there was a design of a second Gridman, who was themed after a European knight. Despite his near-identical appearance to Gridman save his head, Sigma is designed by anime Mecha designer .http://egloos.zum.com/kgm84/v/3334227
