Suicide Squad #6 (2021)

Superboy leads the Squad to Earth-3 on a mission to rescue Bloodsport and capture Black Siren, but first Superboy must battle Ultraman. Meanwhile Waller has sent Peacemaker with a team on a mission to capture Swamp Thing.

When an unidentified drone appears at Belle Reve, the Squad splits into two teams, one to fly into space to investigate the origin point of the drone, the other to follow the map found in the drone. In space, Katana, Harley, Boomerang, and Croc find an old Argent satellite, and find onboard two surviving members of the original Task Force X.

Investigating the map coordinates found in the drone, Deadshot, Enchantress, and El Diablo uncover a diary with the history of the original Task Force X written by King Faraday.

On an Argent space satellite, Katana, Harley, Boomerang, and Croc meet Rick Flag Sr. and Karin Grace, the surviving members of the original Task Force X. Flag tries to recruit the Squad to travel to the Moon to face the Red Wave Monster, a menace that was defeated by the original Task Force X decades ago and imprisoned in a secret prison inside the Moon. Meanwhile, Deadshot, El Diablo, and Enchantress are attacked by robots at an abandoned Argent air base in Nevada.

Several years after World War II, King Faraday is assigned to Task Force X to head Argent, a sister organization to the original Suicide Squad.

Katana, Harley, Boomerang, Croc, and Rick Flag Sr. arrive at the original Task Force X prison for captured aliens on the Moon. They find dead bodies of past Task Force X operatives controlled by a body-possessing alien parasite which attacks them. Meanwhile in Nevada, Deadshot, El Diablo, Enchantress, and Waller are surrounded by Argus robots and must fight their way out.

Faraday and the original Task Force X fight a variety of menaces in the 1950's and 1960's. Things change when astronauts land on the Moon and find a strange creature.

Rick Flag Sr., under the mental control of the Red Wave monster, frees the beast from the Moon prison vault and Harley, Boomerang, Croc, and Katana struggle to stop it before it can reach Earth and end all life there. Meanwhile, Waller, Deadshot, El Diablo, and Enchantress, having escaped from Argus robots at the Task Force X air base in Nevada, must return to the base when Waller learns a secret about it.

Faraday recounts how a prison was built on the Moon to imprison creatures captured by Task Force X. Karin Grace entrusts to Faraday to guard a mysterious object, but Faraday's curiosity backfires on him.

On the Moon, Harley fights against Katana, Boomerang, Croc, and Rick Flag Sr., who are all possessed by the Red Wave Monster. She opens a portal to the Phantom Zone to trap the infected Rick Flag Sr., where he meets his grandson Rick Flag Jr., who had been trapped in the Zone. Meanwhile on Earth, Waller and Faraday come up with a plan to battle the Red Wave Monster, while Karin Grace prepares to make the ultimate sacrifice to stop the beast.

Infected by the Red Wave, Faraday fights to kill other infected Task Force X and Argent agents before he is overcome himself.

Freed from the Phantom Zone, Rick Flag Jr. must lead the Squad to defeat two threats: a growing Phantom Zone rift that threatens to swallow the Squad and the Moon, and the Red Wave Monster who is growing in power and if not stopped could destroy all life on Earth.

In the aftermath of the defeat of the Red Wave Monster, Karin Grace and King Faraday find they are still infected by the Red Wave energy. Karin escapes while Faraday remains in custody at Belle Reve.
