  • Thunder Subtitle: Combined Super God (合体超神 Gattai Chōjin)
  • King Subtitle: Combined Dragon Emperor (合体竜帝 Gattai Ryūtei)


According to Kazumitsu Akamatsu, Gridman's designer, he was employed by Takara to come up with a design for a Kyodai Hero called Cyberman, which was much like Toho Company's Dennou Keisatsu Cybercop. The hero was apparently human-sized and would be able to combine with support mechas to achieve a total height of 4m. After some internal review, the project was scrapped and he was moved to the production team of another Tsuburaya Hero, Bigman, because of his knowledge in Tokusatsu, and to be a liaison between Tsuburaya and Takara. He accepted the role, knowing that Tsuburaya were experts in the Kyodai Hero genre. This conceptual hero would eventually be reworked into Gridman. After that, he also worked on the designs of the monsters with the help of former Takara employee Osamu Yamaguchi. After designing Chidogerah, he stopped designing monsters and focus more on the background scenes. He also came up with the names of the Assist Weapons and the names of the characters, and thinks of the work as if it were his own child.

While tracking down Khan Digifier he encountered Naoto and, seeing that Naoto had a good heart, chose him to merge with whenever battle must be done within the Computer world. To fight the larger and more powerful monsters, Gridman receives the upgrade program P-L6806OX to grow gigantic and battle against his foes. However, this massive power-up last only for a few minutes as it could overload Junk's system. When the power up begins to fade, a blue light on Gridman's head begins to blink as a warning. Naoto, Yuuka, and Ippei chat with Gridman over their computer by typing messages to him.

Main article: Category:Assist Weapons

Assist Weapons (アシストウェポン Ashisuto Uepon) are created and devised by Ippei to assist Gridman in battle. When in the Computer World, Gridman uses the Materialization Beam to complete the process of bringing them into battle.

Initially, Yuka was responsible for handling the programs until Ippei created the Assist Weapon Selecter (アシストウェポンセレクター Ashisuto Uepon Serekutā) to contain and deploy them easily. With the exception of Gridman Sword, later Assist Weapons (being mechas themselves) are remotely controlled by both Ippei and Yuka through game controllers. They are also modified to become powered suits for Gridman, thus raising his ability perimeters. In the final episode, Khan Digifier invaded Junk's server and destroy all the Assist Weapons in their data forms, leaving Gridman almost defeated before Takeshi created the Grid Hyper Beam program.
