Gridman the Hyper Agent: The Demon King's Counterattack

is a series of photo novels from Shogakukan Televi-Kun, running from May to November 1994. It is a spin-off of Gridman the Hyper Agent and features the younger brothers of Gridman and Kahn Digifer, Gridman Sigma and Neo Kahn Digifer respectively.
==Conception==
Gridman the Hyper Agent was supposed to end with not more than 30 episodes, but due to its surprising popularity, additional succeeding episodes were to be produced. Unfortunately, only 39 episodes were produced due to production problems.
Wanting to find a way for Gridman's popularity to continue, Kazumitsu Akamatsu proposed a photo novel plan as a sequel work for Gridman. The only returning actors are Masaya Obi and Tsuyoshi Sugawara, who reprise their characters Naoto and Takeshi as photos. The former antagonist character Takeshi Todo bonds with Gridman Sigma and assisted Gridman/Naoto Sho in against Neo Kahn Digifer's army of monsters.
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 Khan Knight, a rival character and Kahn Digifer's servant, before redeeming himself as Grid Knight. 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 , Sigma is designed by , known for the Mobile Suit designs in Mobile Suit ZZ Gundam.http://egloos.zum.com/kgm84/v/3334227
For appearing monsters, the least requirement of budget allowed the production team to create them as clay models. The models' heights were around 50 cm to 1 m. The only exception goes to Neo Metallus who was represented by a slightly altered version of its original suit and Geist Digifier, represented by a plastic model.https://star.ap.teacup.com/karzworks/273.html
