Damage is a DC Comics superhero who first appeared in a comic book of the same name during the Zero Hour crisis. He is the son of the original Atom Al Pratt. He has been a member of the Titans, and the Freedom Fighters, and is currently a member of the Justice Society of America.
A superhero/supervillain battle, involving Baron Blitzkrieg, Iron Munro, and others, results in extensive damage to downtown Atlanta. Damage is arrested for his part in the extensive damage. Sarge Steel is able to cut a deal for him: he would be banned from Georgia and remanded into custody of the then federally-sponsored Titans team, led by Arsenal. Around this time Damage deals with, emotionally, the murder of a fellow schoolmate he cares for at the hands of a supervillain. After a while, Damage leaves the Titans to find his origins.
When the original five Titans reformed the group, Arsenal nominates Damage for membership. Arsenal managed to erase Grant's criminal records, so he was no longer a fugitive, and Grant joins the team. Grant participates in multiple adventures, including a confrontation with demons from hell in "Day of Judgment" #1. Later, Damage confronts something he had buried for a long time: he had been victim of abuse at the hands of his foster father. After opening up to Roy Harper, Grant takes a leave of absence and sought peace and healing on the Navajo reservation where Roy was raised.
He helps the current Justice Society of America against Imperiex and the villainous team of Obsidian, Eclipso, and Mordru, both times as part of a modern All-Star Squadron. He has since been seen with a new team of government-sponsored Freedom Fighters, whose activities are yet unknown. He also has something of a brotherly relationship with Atom Smasher, the godson of his father, the original Atom. It was thought that Grant had a brother, Walter, who was recently killed by Walter's superhero daughter, Manhunter, aka Kate Spencer. However, it turned out that Walter was actually the son of Iron Munro and Phantom Lady - an odd parallel to Damage's paternity search, as at one stage it appeared that Grant might be the couple's child.
Several members of the modern Freedom Fighters team were killed by the Society in Infinite Crisis #1. Damage was one of the survivors, though his face is severely scarred by Zoom, although this isn't revealed until later .
Damage appears in the relaunched Justice Society of America released in December 2006. He wears a full mask and a costume similar to that of his father and Atom Smasher, featuring a biohazard symbol. He also has a significantly gruffer and more cynical attitude, partly because, as the villain Rebel insinuates, Damage was left badly scarred, but alive, by Zoom. Zoom later encounters the Justice Society, claiming to have maimed, but not killed, the boy intentionally, to give him a defining tragedy, and the fight leads to Georgia. Damage leaps into the state, although he is banned from entering, and catches up with Zoom, and holds him hostage. Liberty Belle calms Damage down, but Zoom escapes and hurls debris at his face with the intent to kill him. Liberty Belle speeds in, saves Damage, and knocks out Zoom Damage remains on the team, essentially in Atom Smasher's place (the Thunderbolt has even called him "Atom Smasher Two" jokingly).
Damage's face is later healed by the reborn Gog. . This is enough to restore his former cheerful and outgoing personality, pushing him to attempt making contact with the new Judomaster. Since no one of them can understand the language spoken by the other (Grant doesn't know Japanese, while Judomaster can't speak or understand English), their relation is stifled
