Who is Johnny Thunder?

Born on the seventh day of the seventh month at 7 AM, Johnny Thunder was mystically linked at birth to a powerful genie-like being called the Thunderbolt, whom he could summon—often accidentally—by saying the magic words "Cei-U." He later served with the Justice Society of America.

Few characters carry the warm, crackly magic of the Golden Age quite like Johnny Thunder, who burst onto the scene in the very first issue of Flash Comics back in 1940, courtesy of creators John B. Wentworth and Stan Asch. That landmark debut — itself a collector's holy grail — placed him at the absolute ground floor of the DC Universe, sharing pages with luminaries like Jay Garrick, Carter Hall, Alan Scott, The Atom, and Wonder Woman, the very titans who defined an era. His footprint stretches across Flash Comics, Justice League of America, and All-Star Squadron, with a remarkable 12 key-issue appearances that any serious Golden Age collector will recognize on sight. Over 86 years of publication history, Johnny Thunder remains a living thread connecting comics' earliest heroic mythology to the present day — a genuine piece of the foundation.
