[1] Frustrated that the United States did not seem to be dealing with crime or Nazi saboteurs, radio operator Jerry Carstairs created a costume with a built-in microphone and fought for justice as the Thunderer.

[2] In his first recorded appearance, Jerry learned that radio station WWLX was really a front for Nazi Fifth Columnists who were transmitting secret messages hidden in music.

[3][4] Thunderer later uncovered the machinations of a hideously deformed dwarf named Gore who hated beautiful people so much that he rigged Morse code death traps to kill his victims over the radio.

When Red Skull was defeated, the heroes used the Cosmic Cube to wipe out the Black Avenger's memories of the event to preserve history.

[10] During the "Last Days" part of the Secret Wars storyline, Thunderer is seen as a resident of Valhalla Villas (a retirement home for ex-heroes and ex-villains in Miami).

The Thunderer appears in the Spider-Man five-part episode "Six Forgotten Warriors", voiced by Hansford Rowe in the present and Brett King in a flashback.

The Thunderer is the last to be located, as he had stayed close to the base the Doomsday machine was held in to guard it while disguised as a homeless man.
