Captain Boomerang

Intro George "Digger" Harkness was a notorious criminal from Australia and a member of Task Force X. Harkness was raised in poverty in Korumburra, the illegitimate child of Betty Harkness and W. W. Wiggins. Harkness learned early how to develop boomerangs into weapons. Having moved to the US, Harkness undertook a string of jewelry heists in Central City which brought him to the attention of the Flash, who eventually apprehended him during another robbery. Earning the name Captain Boomerang from his father later in his life, Harkness became an infamous bank robber, renowned to be among the most lethal robbers in the world with 54 counts of aggravated assault and 98 counts of burglary to his name. During his time in Belle Reve, Harkness was serving three life sentences when he was recruited by Amanda Waller to enlist in the government-sanctioned Task Force X, where he was assigned to neutralize the threat of Enchantress and Incubus in Midway City, shortening his prison sentence as a result. Years later, Harkness went on the run and was wanted by the Gotham City Police Department. In 2020, Harkness was recruited once again for a new grouping of Task Force X to stop Project Starfish in Corto Maltese, but his mission would not go well, as Harkness and most of the team were killed.
