As Waller and the squad await helicopter extraction, they are attacked by Joker, who learned of Harley's predicament. With tech stolen from an A.R.G.U.S. laboratory, Joker disables Harley's bomb, and helps her escape. Waller shoots down Joker's helicopter, though Harley survives and rejoins the squad, believing Joker is dead. Enchantress captures Waller to regain her heart. Deadshot finds Waller's top-secret files and discovers Flag's relationship with Moone. The team abandon Flag, sharing a drink in an abandoned bar, where El Diablo reveals his powers and criminal lifestyle led to the deaths of his family. Flag relieves the squad of their mission, but realizing they have the opportunity to prove themselves, the group set out to save the city.
The squad attack Enchantress, while Killer Croc and Flag's platoon of Navy SEALs plant a bomb beneath the subway to kill Incubus. El Diablo embraces his pyrokinesis, sacrificing himself to maneuver and keep Incubus in the right spot. Enchantress invites the squad to join her, and Harley pretends to be tempted to get close enough to cut out Enchantress's heart. Flag crushes her heart, killing her and releasing Moone. Waller deducts ten years off each squad member's sentence and fulfill their requests (except for Boomerang, who is instead detained). Joker, who is still alive, breaks into Belle Reve and rescues Harley.
The Suicide Squad is a team of imprisoned super-villains who perform high-risk missions for the U.S. government in exchange for commuted sentences. Formally known as Task Force X, the team's actions are highly classified, and the government is able to deny any involvement by claiming that they are not responsible for the damages of a random super-villain attack. Their commander is Amanda Waller, who runs the organization out of Belle Reve prison. Surgically implanted with remote explosives in their necks to discourage them from disobeying orders, the roster for the squad constantly changes and members of the group are often killed during missions.
9 months after the death of Superman depicted in Batman v Superman: Dawn of Justice, government agent Amanda Waller proposes to assemble a squad of incarcerated criminals and metahumans that she controls and to place them under the command of Colonel Rick Flag, a highly skilled and decorated soldier. The team, labeled by her as "Task Force X", are intended to be used to intervene in deadly missions for the United States government concerning the supernatural. The members of the team, who became known as Task Force X are recruited for service by Waller and Flag, and are offered reductions to their sentences in exchange. The members are implanted with explosive devices in their necks so Waller and/or Flag can kill any of them should they attempt to escape or directly disobey an order.
Waller then calls on Task Force X to extract a valuable person from Midway City. The Squad; assassin Floyd Lawton (Deadshot), former psychiatrist Dr. Harleen Quinzel (Harley Quinn), robber Digger Harkness (Captain Boomerang), pyrokinetic Chato Santana (El Diablo) and the reptilian mutation Waylon Jones (Killer Croc) are implanted with the nano explosives and given their gear. Flag briefs the squad on how they are to go about accomplishing their mission. Just before their departure, the squad is joined by additional members; the rope wielding Christopher Weiss (Slipknot) and Tatsu Yamashiro (Katana), a mystic sword wielder to serve as Flag's bodyguard.
The Enchantress, sensing the squad's approach and intentions, attacks their helicopter causing it to crash. The squad now has to proceed on foot. Along the way, Captain Boomerang convinces Slipknot that there are no bombs in their necks and it is only a ploy. Slipknot attempts an escape, grappling up a building, but is killed when Flag activates the bomb demonstrating that they are no ruse.
Waller calls for a helicopter extraction and the squad escorts her to the rooftop. The helicopter arrives, but it has been commandeered by the Joker and his gang. Once they discover this, Flag and his squad open fire on the helicopter, which fires back in turn. Once in range, the Joker deactivates the nano bomb in Harley's neck, permitting her to board the helicopter and is reunited with the Joker. Waller orders Deadshot to shoot Harley but he misses, deliberately.
Harley then returns to the squad while Deadshot discovers confidential documents abandoned by Waller which reveal that both she and Flag have been misleading the team. The squad subsequently decides to abandon the mission while Flag and his men choose to continue. The squad go to a bar but realize that they have a chance to prove themselves. They are joined by Flag who destroys the controls for their neck explosives. The squad joins him and pinpoint the Enchantress and Waller at the railway station.
Injured from battle, Enchantress propositions the squad to fulfill their sincerest longings in exchange for their allegiance. Harley mocks an intention to accept, approaching Enchantress to get near enough to cut her heart free with Katana's sword thereby reducing her power significantly. Captain Boomerang then finds the heart idol and gives it to Flag who eventually crushes it, killing the Enchantress and freeing June. Waller, still alive, emerges and the squad members are returned to Belle Reve and given ten years off their sentences. All but Captain Boomerang are allowed special privileges; Harley is given an espresso machine, Deadshot is allowed to visit his daughter Zoe (supervised) and Killer Croc is given a television set with cable access.
Catching Frost, who was convinced by Riddler to let him diffuse the nano-bombs, the Squad decided to spare him. Waller soon discovered what they were doing, activating the bombs; however, only King Shark and Black Spider perished. The rest of the squad survived thanks to the electroshock machine zapping the bombs.
Free of Amanda Waller and their explosive collars, Harley Quinn, at the direction of her new partner, Penguin, reformed the Suicide Squad. This new squad would consist of Quinn, Deadshot, Captain Boomerang and Killer Croc, though they had to free Croc from GCPD custody first. They were hired by Penguin to murder Bruce Wayne, who was leading the efforts to renovate the old Arkham City. After staking out Wayne's movements for nine hours, they attacked his car, thinking to pluck the billionaire out of it once it was disabled, however, when the window rolled down, they met Batman instead.
The Squad appears as the main focus of the Justice League Unlimited episode "Task Force X." The team goes by this name throughout the episode due to the potential sensitivity of the word "suicide." Team members who appear are Rick Flag, Deadshot, Captain Boomerang, Plastique and Clock King. The team is sent by Amanda Waller to infiltrate the Justice League Satellite and disable the laser weapon inside.
