Nick Kovak was a federal agent, working undercover in the Keystone mob scene under the alias Nick Kelly. He fed all the information he learned straight to the Justice Department. The bite of an alien parasite gave him super-powers, tripling his strength and agility and giving him thermal vision. He used these powers to fight crime as Argus.
Argus operated in Central City, where he became an initially rather hostile companion to the Flash (Wally West), although the two heroes learned to tolerate each other.
