Suicide Squad: Kill the Justice League - Season of the Joker

Suicide Squad: Kill the Justice League – Season of the Joker launched on March 28, 2024, introducing Joker as a playable character, a Joker-themed Elseworld location, new missions, additional gear sets, and a Battle Pass with cosmetic items. The update is available for all platforms as a free expansion.

Following the defeat of the first Brainiac, the primary Brainiac begins to phase parts of other worlds into Earth-1 and enhances his troops. Waller sends the squad to "Joker Earth", an alternate universe where Brainiac terraformed Metropolis using the DNA of the Joker, who killed his own Suicide Squad and A.R.G.U.S. forces in a failed suicide bombing attempt to kill Brainiac. The squad battles the second Brainiac, who takes the form of Green Lantern, and defeats him. The squad then captures the Joker and takes him back to Earth-1, where he agrees to join them in the ongoing war against Brainiac's forces. As the battle continues on Earth-1, Brainiac adapts his forces by infusing them with Green Lantern's DNA, giving them his powers. The squad returns to Joker Earth once more to confront the third Brainiac, who takes the form of Superman, and emerges victorious.
