Gridman (グリッドマン, Guriddoman?) is a 'policeman' from the Hyper World, a parallel world to the "Computer World" a world within all computers. 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.
