Happy Birthday: Captain Boomerang
George “Digger” Harkness was born to an American soldier and an Australian woman. An illegitimate child, Harkness grew up in poverty but quickly discovered a talent for both crafting and using boomerangs.
As a young man, he got a job working for a toy company, demonstrating the use of their boomerangs. When audiences ridiculed him, Harkness turned to crime instead, keeping his costume and creating specialized boomerangs to become Captain Boomerang.
He became a member of the Flash’s Rogues Gallery, though years later he joined the Suicide Squad in order to be pardoned for his crimes. Harkness later returned to his criminal ways but was increasingly outclassed by both heroes and other villains.
He eventually became so desperate he accepted small jobs working for other crooks. His last act was an assignment to kill Jack Drake, the father of current Robin, Tim Drake. Harkness succeeded, but Drake managed to shoot and kill him as well.
