John Broome was an American comic book writer whose work, primarily for DC Comics, forms the basis for the anime film DC Super Heroes vs. Eagle Talon. In that production, he receives credit as an original creator for the character of Barry Allen, the Silver Age Flash. Broome was born Irving Broome on May 4, 1913, and began his career writing for science-fiction pulp magazines before transitioning to comics in the 1940s. He died on March 14, 1999.

Broome’s most significant contributions came during the Silver Age of comic books, where he worked closely with editor Julius Schwartz. He was the primary writer for the revived Flash series, co-creating the Barry Allen version of the character and many of his iconic adversaries, including Captain Boomerang, Abra Kadabra, and Professor Zoom. He also co-created the Elongated Man. In 1959, Broome and artist Gil Kane introduced the Hal Jordan version of Green Lantern, a character he would write for over a decade. During this period, he co-created key elements of the Green Lantern mythos, such as the villain Sinestro, and supporting characters like Star Sapphire and Guy Gardner.

Beyond these flagship characters, Broome’s writing credits from the 1950s and 1960s include contributions to Batman, where he was part of the creative team that gave the character a New Look in 1964, and the creation of other enduring DC characters such as the Phantom Stranger and Detective Chimp. His work was recognized with an Alley Award in 1964, and he received an Inkpot Award in 1998. In 2009, he was posthumously awarded the Bill Finger Award for Excellence in Comic Book Writing.

Broome retired from writing comics in 1970, subsequently traveling and teaching English in Japan before his death in Thailand in 1999. His significance in the industry lies in his foundational work on many of DC Comics’ most enduring superheroes, a legacy that continues to be adapted across media, including the Japanese-produced animated feature DC Super Heroes vs. Eagle Talon.
