Digger Harkness

George "Digger" Harkness, is an Australian criminal who specialized in throwing boomerangs with deadly accuracy. He is a member of the Rogues, and thus an enemy of the Flash.

Origin
Though he liked to make up fake stories about his origin, the truth was, from an early age, George "Digger" Harkness taught himself how to carve and throw boomerangs extremely well, having known his absentee father was especially proficient with them. Young Harkness believed that, if he could become better with boomerangs, it would somehow impress his father if they were to ever meet again.

When he was older, Harkness was determined to become a master thief with his boomerangs. He managed to rob every bank in Australia at least once before he decided to move to the United States for his next target. There, he started his life of crime in Central City before meeting Leonard Snart, who invited him to be a part of the Rogues due to his skill in thievery and his dangerous weaponry.

S.T.A.R. Labs Heist
After robbing a bank of its money, the Rogues are in their warehouse planning their next heist. Leonard informs the team that they are going to hit a S.T.A.R. Labs Convoy next in order to steal the tech onboard, which is rumoured to be worth millions on the black market. Hours later, at night, they commit the plan to detail and the Rogues grab as many cases of tech as possible.

Choosing their weapons
After robbing the S.T.A.R. Labs convoy, the Rogues regroup in their warehouse. Leonard instantly goes towards planning their next job, but Mick Rory grabs the flamethrower and starts messing around with it. Leonard casually tells him to put it down, per usual he has to control Mick from going too far, but instead of complying Rory just turns it on and starts bursting flames in the air, roaring with laughter. Leonard scolds him as he's trying to concentrate but Lisa tells him to calm down as they got the job done. Mick reminds him the tech is supposed to pay off their debt but why not kill the people trying to blackmail them. Leonard thinks about it and takes a weapon to his desk, claiming it to be his. This results in Digger deciding to open a case for himself only to see a high-tech boomerang inside one of them. Thinking it was fate that he was with the Rogues since it was only because of them that he now has this boomerang to impress his father with, this solidified his position with them.

Central City Fine Jewellery Heist
The Rogues decide to rob a jewellery store with their new weapons and so by the time the Flash arrives, the floor was covered in golden ice as well as most of the store being empty. The 4 rogues are at the back of the store while The Flash blocks the entrance. The Flash tries taking them on but the Rogues used their weapons to stop him, allowing Harkness to throw an explosive boomerang at the speedster, throwing him out of the building in incredible pain. Before the Flash can regain his balance, the Rogues were already gone.

Second fight with the Flash
The Rogues were planning their next heist before they noticed the Flash had come close to their perimeter. Leonard tells the Rogues to get ready and by the time the Flash entered the warehouse, they were already ready for him. He tries taking them on one at a time but they had each others backs and so the Flash couldn't get close. He was hit by their weapons again and again, damaging his suit and causing him to nearly fall unconscious. Eventually, Harkness throws another explosive boomerang which thrusted the speedster out of the warehouse. Before the Rogues could finish him off, however, the Flash ran away.

Central City Casino Heist
The 4 Rogues decide to rob the Casino the next day and it's going fine until the Flash enters the building to stop them. Mick and Lisa try stop the Flash while Leonard and Harkness collect the money but he uses their tools against each other before taking them out using his super speed. Leonard tells Harkness to buy him some time and so he does so by trying to use his boomerangs to catch the Flash off-guard but he uses his speed to knock him unconscious before he could do any damage. After being tied up and arrested by the Flash, he was given the nickname "Captain Boomerang" by Iris West and her article on the Rogues, which led him to become fond of the name.
