Johnny Thunder operated as a self-named and non-costumed "mystery man" who commanded a Bahdnesian "hex bolt" called the Thunderbolt during World War II as a member of the Justice Society of America.

Fellow member Al Pratt (Atom) never really saw Johnny as a hero, but more as a "weird guy" that the Justice Society members had put up with because of his "pet Thunderbolt". After the war, Thunder traveled to Tibet where he was born in order to find himself, only to return to the United States when the Chinese Communist army invaded that country. He found Pratt working for Tex Thompson's campaign office as part of the Federal Bureau of Superheroes and, by using his Thunderbolt to get Pratt's attention, got hired on as part of the politician's promotion team.

At a rally in Washington, D.C. in 1950 where all costumed superheroes were to appear by Presidential decree to show their loyalty, Joan Dale (Miss America) publicly exposed Tex Thompson as being the Ultra-Humanite and attempted to also expose Dynaman as being Adolf Hitler in Daniel Dunbar's body when the Ultra-Humanite had Robert Crane (Robotman) silence her by murdering her in public. After the subsequent exposure of Dynaman by Rex Tyler (Hourman), which resulted in his fighting the various superheroes gathered at the rally, Thunder commanded his Thunderbolt to kill Hourman, which made the Thunderbolt so confused as to where he would stand in both his personal ethics and his obedience to his master that he just totally departed from the scene, leaving Thunder completely on his own.

Years later, following the deaths of Dynaman and Ultra-Humanite, Johnny Thunder's personal life wasn't going very well, to say the least.


By saying "Cei-U" (pronounced "say you"), Johnny Thunder had access to the genie-like Thunderbolt whom he can control for one hour. However, the Thunderbolt cannot make decisions of his own in regards to ambiguous commands given to him by his master.
