Digger Harkness, better known as Captain Boomerang, is an infamous Australian bank robber, and is renowned to be among the most lethal robbers in the world, having 54 counts of aggravated assault, and 98 counts of burglary to his name.
He would later be forcibly recruited into Amanda Waller's Suicide Squad, and his teammates and him ultimately succeed in their mission to defeat of the Enchantress and Incubus mystical duo, and got his prison sentence shortened as a result. Captain Boomerang is a tough, sarcastic, humorous and somewhat crude individual who has no qualms with theft, beating counts of aggravated assault, or killing, going so far as to trick Slipknot into trying to escape the Suicide Squad and subsequently getting himself killed, just to test if the implanted nano-bombs were actually real, not wanting to risk his own life. Despite that, however, Harkness isn't completely devoid of empathy, greatly respecting Deadshot's refusal to kill Harley Quinn, sympathizing with Deadshot's inability to save Harley, being depressed and shocked after learning El Diablo's dark secret.

A Fresh Target
The deranged boomerang-thrower continued to clash with the Flash during his criminal activities, such as when he tied the unconscious metahuman to his Rocket Boomerang only to be captured again when the lightning fast vigilante was able to free himself. In their last encounter, the Flash caught Boomerang participating in the heist on a diamond exchange. There, the captain betrayed one of his associates, throwing a boomerang at the man's head to knock him out before collecting the loot for himself. Before he could leave, he was swiftly and easily incapacitated by his old nemesis and later put behind bars in Belle Reve, where he spent this time lashing out at guards from inside Cell D-108.
Joining Task Force X
Captain Boomerang joined the Suicide Squad right outside of Belle Reve, shortly before they were about to fly out to their destination to Midway City. He was transported in a yellow body bag, and when let free, instantly lashed out against some soldiers. He was welcomed by Rick Flag and shortly afterwards traveled to Midway City with the rest of the Squad, with their collective goal being to stop the mystical duo of Enchantress and Incubus.
Tricking Slipknot
The Suicide Squad crash-lands in Midway City, and Boomerang, secretly wishing to test how real the implanted nano-bombs are, promptly tricks Slipknot into believing that the bombs are a fake bluffing tactic of Amanda Waller, which leads to both Slipknot and Boomerang attempting to flee, with Katana subduing Boomerang and Rick Flag activating the nano-bomb, exploding Slipknot's head and killing him. Boomerang, having his suspicions confirmed, wisely chooses to stay with the group. Attracted to Katana, Boomerang asks if she has a boyfriend.
Battling Enchantress's Minions
Soon after, the group encounters weird looking creatures. When Rick Flag approaches them, the creatures became hostile and attack. Instead of fighting with the rest of the squad, Boomerang cracks open a can of beer and watched the fight. However one of the creatures attacks him, bringing him into the fight. During the fight, Boomerang's pink unicorn falls on the ground. After taking down a few creatures Boomerang and the rest of the squad watched as Deadshot gunned several creatures from atop a car until they were all gone. After the battle Boomerang picks up his pink unicorn and chastised El Diablo for not helping during the battle.
Retrieving HVT1
Continuing the fight through the city, the Squad heads into a building their target is residing in. They encounter resistance in numerous Eyes of the Adversary that were formerly soldiers that were accompanying them; as Flag's death meant their own, the Squad was forced to fight with the objective of protecting him. The group is lead to where their target is residing, being told to wait while Flag brings them out of their safe room.
Drowning Sorrows
Having drinks, Boomerang listens as Deadshot explains that they were meant to be patsies to take the blame for everything going on; for a brief moment he had hope. El Diablo quips that a killer having hope wasn't something he thought was possible, explaining about his past. To Boomerang's shock, Diablo once had a happy married life with children, despite being an arsonist-for-hire in the gang world. One night, however, Diablo anger and powers cost him his family.
