Captain Boomerang

Born in Australia but raised in poverty in the U.S., George 'Digger' Harkness developed an uncanny mastery of boomerangs and was hired to promote them as Captain Boomerang. When the gig soured, he turned to a life of crime, becoming one of the Flash's most persistent rogues.

Few Silver Age villains have proven as stubbornly, gloriously enduring as Captain Boomerang, who burst onto the scene in The Flash #117 in 1960, conjured by the legendary creative duo of John Broome and Carmine Infantino. What began as a colorful rogues' gallery entry in one of DC's flagship titles has blossomed into a six-decade-plus career spanning well over a century of catalog appearances and six key collector issues — a testament to just how much readers keep coming back to this guy. He's made himself at home across Suicide Squad and multiple Flash series, sharing pages with the heaviest hitters in the DC Universe — Superman, Batman, Green Lantern, The Flash himself — which tells you everything about the kind of high-stakes company he keeps. Whether you're a Silver Age purist or a modern DC devotee, Captain Boomerang is the kind of character whose longevity demands respect and whose appearances reward the hunt.
