Denkou Choujin Gridman (電光超人グリッドマン, Denkō Chōjin Guriddoman; lit. Lightning Superhuman Gridman), known as Gridman the Hyper Agent in some English-speaking territories, is a 1993–1994 Japanese tokusatsu "Giant Hero" series created by Tsuburaya Productions (the producers of Ultraman) and would be Tsuburaya's last non-Ultra superhero production before Bio Planet WoO. It was the inspiration and source material for DiC Entertainment's Superhuman Samurai Syber-Squad.
Shot on live video, Gridman was the first series by Tsuburaya Productions to utilize D-2 digital video for its special effects scenes, allowing for smoother slow-motion photography. Tsuburaya, having switched to digital techniques since then, would continue to use D-2 for all future productions.
