Incident Reports

Arkham Origins Incident

Captain Boomerang was mentioned by one of the 20 escaped Blackgate Prisoners in Batman: Arkham Origins. The prisoner told the thugs around him that he needed a place to hide because: "It's some guy with a boomerang!". The other thugs thought that he meant Batarang and were talking about Batman, but the prisoner told them: "No. It's definitely not the Bat. Dressed totally different. Calls himself Captain and... Look can we finish this conversation somewhere else? Somewhere SAFE?" It seemed as if Captain Boomerang had a grudge against that particular prisoner.

Assault on Arkham Incident

Captain Boomerang appeared as a member of the Suicide Squad. He was first seen in a prison getting food when the prisoner next to him tried to stab him. George threw his food tray at the prisoner, which demonstrated his skill with a "boomerang". Boomerang later woke up and realized that he had been recruited for another Suicide Squad mission. He was one of the three characters who had previously done Suicide Squad missions before, along with Deadshot and Harley Quinn. Throughout the film, Boomerang was a rival to Deadshot as to who was the leader of the squad, even though it was clear to everyone else that Deadshot lead the group. When the team was sneaking into the Arkham Asylum, he was disguised as a EMT with Killer Frost naked in a body bag. He tried to sarcastically show the guards that the body was dead and he hit the body bag as well as Killer Frost's head, much to her pain and anger. They made it through security and after Killer Frost got out of the bag, she hit him in the groin as payback. Later on, when they were racing to get to the helicopter, Deadshot shot Boomerang in the shoulder which made him believe that he was no longer a threat. Deadshot ran into the helicopter and began to take off. As the helicopter ascended, Captain Boomerang put him in a headlock. Deadshot was surprised that he had made it into the helicopter. Boomerang told him that only one of them was getting out of there. Deadshot pulled back on the control stick with his legs which sent Boomerang falling out the back of the helicopter and into a group of prisoners. He survived the fall and yelled that he'd get payback on Deadshot.

Before Arkham Knight Incident

Captain Boomerang and Deadshot once again worked together under the leadership of Harley Quinn after she managed to reform the Suicide Squad. In their first mission together, Boomerang destroyed a GCPD helicopter, and caused it to crash into the armored transport that was taking Killer Croc to Stone Ridge Penitentiary. They freed Croc from the vehicle and traveled to Wonder City where they met Harley's partner, the Penguin. Penguin hired the 'All-New Suicide Squad' to murder Bruce Wayne. Though the animosity between him, Harley, and Deadshot was still obvious, together, they attacked Wayne's car on its way home from a construction site that they had staked out. Unfortunately, it was Batman, not Wayne, who emerged from the car. A fight soon broke out between Harley and Batman, during which Boomerang collected thrown Batarangs and threw them back at the Dark Knight. Boomerang then got the upper-hand as he then started throwing explosive projectiles before he was suddenly executed by Deadshot, for "rarely showering."
