After Dr. Silas Stone used his technology to convert his son into Cyborg, some technology manifested that wanted Cyborg to get information on metahumans. When he fought the controls, the secondary cybernetic systems began to hunt passively for information. Cyborg began to refer tothe software as the "Grid." As it grew with every computer intelligence, it developed quirks and traits from the hackers and viruses that it encountered. Its full sentience was brought out by Atomica where she used it to steal the date of the Justice League's adventures during the events of the "Trinity War" storyline. When she betrayed the Justice League upon revealing her allegiance to the arrival of the Crime Syndicate of America, Atomica brought Grid into the group. When it joined the Crime Syndicate, it got what it wanted: a body made from Cyborg's robot prosthesis and emotions. During the "Forever Evil" storyline, Grid served the Crime Syndicate as their datahub in their plan to take over the world. He starts by cutting power to all major cities, and orchestrates the release of all prisoners from the world's superhuman prisons. Grid continues to examine case files for the Crime Syndicate members attempting to learn how to feel, and sees Power Ring, Johnny Quick, Atomica, and Deathstorm's histories of how they gained their powers. However, he is unable to view Superwoman's history as her file has been deleted to which he states that if he had feelings, it would now be suspicion. With he had the Metal Men reactivated, Cyborg informs them of Grid as they head to Happy Harbor to take on the Crime Syndicate. Cyborg lures Grid out and the Metal Men begin attacking him. Grid brings Society members to help as Grid enters Cyborg's new body. Cyborg is able to trap Grid in his body as the Metal Men defeat the Secret Society of Super Villains members that are present. During the "Darkseid War" storyline, Grid is still in Cyborg's body at the time when the surviving Crime Syndicate members and the Justice League in a plot to end the conflict between Darkseid and the Anti-Monitor. Grid is able to make Cyborg become it. When the fight was over, Grid and Owlman were the remaining Crime Syndicate members where Owlman has Grid downloaded into Metron's Mobius Chair. The two of them are seemingly destroyed by a powerful entity.

In other media
Grid appears in the 2017 video gameInjustice 2, voiced by Khary Payton. In the story, Brainiac creates Grid by briefly taking over Cyborg's body to create a clone of him deprived of Cyborg's humanity. Grid then fights Cyborg or Catwoman and is defeated by either one. He appears as a "Premier Skin" for Cyborg in the main game, and his character intros reveal that his new task is to achieve human emotion.
Grid appears as one of the central antagonists of Lego DC Super-Villains, voiced by Bumper Robinson. This version of Grid has emotion and is from the same reality as his teammates are, being portrayed as the Earth-3 counterpart of Cyborg, as opposed to his comic origins. He and the Crime Syndicate pose as the Justice Syndicate at the time when the Justice League went missing. "Have a nice day." is Grid's catchphrase here. Later, during the Legion of Doom's assault on the Syndicate on top of LexCorp, Grid and Deathstorm are fought against Deadshot, Captain Boomerang, Rookie, Harley Quinn, Catwoman and Solomon Grundy, with Grid eventually destroyed in the end.
In the DC Universe show, Doom Patrol, Cyborg refers to his computer AI as "Grid", somewhat similar to its comic book origins. In the episode, "Hair Patrol", Grid activated Cyborg's sonic cannon against the cybernetic hero's wishes; causing him to question his A.I.'s capabilities. In "Frances Patrol", Cyborg finds out that Grid has secretly been enhancing him so he'll go from mostly human to mostly machine. He later tells Jane that he's starting to not trust Grid anymore and is unsure of what to do. At the end of the episode "Cyborg Patrol", it was revealed to be a trick by Mr. Nobody to have Cyborg go crazy and beat up his father Silas Stone for no good reason. While Silas is in critical condition, Rita helps Cyborg reinstall Grid as he stays by his father's side.
