In the aftermath of Superman's death,[b] intelligence officer Amanda Waller convinces the U.S. government to greenlight Task Force X, a response team of criminals and supervillains. The team will be used to combat metahuman threats, under Waller's control via nanite bombs implanted in each criminal's neck, which can be remotely detonated if they try to rebel or escape. If successful, they will have their sentences shortened.

Dr. June Moone, an American archaeologist, becomes possessed by a witch called Enchantress. Waller can control Enchantress by seizing her magical heart, which wounds her if it is struck. Waller's subordinate Colonel Rick Flag is in love with Moone, and is made a lead member of Task Force X. However, Enchantress betrays Waller, conquering Midway City, transforming humans into monsters, and summoning her brother Incubus to destroy mankind.

Task Force X is formed to stop Enchantress, using seven inmates from Belle Reve penitentiary. The roster consists of hitman Deadshot, who wants to reunite with his daughter Zoe; Harley Quinn, a volatile and crazed former psychiatrist-turned-girlfriend of Gotham crime lord Joker; Australian boomerang-wielding thief Captain Boomerang; pyrokinetic ex-gangster El Diablo; mutant cannibal Killer Croc; and rope-climber mercenary Slipknot, and then there’s You, Your power is unknown but it has to do with shadows, but it goes way beyond just simply shadows, You can teleport through them, manifest things from them, you could even summon black inky tentacles from them, You also can regenerate but it’s slightly limited, control over pain tolerance, and last but not least you can levitate, your eyes Glow purple every time you use your powers. The team is led by Flag and joined by his associate Katana, a Japanese swordswoman. Waller and Flag deliberately hid the latter's relationship with Moone from the team.

After being injected with the Nino bomb you were outside with the other criminals, there was duffle bags or crates of everyone’s things in it to get ready to go. Weapons or clothes that belonged to everyone with their specific crate or duffel bag.
