Backlash (Marc Slayton)

Backlash is then assigned to join and spy on StormWatch, the U.N.'s crisis-intervention superteam. He works as the group's field leader and instructor until he loses several members of the first team (later dubbed Stormwatch Prime) during a mission in Kuwait. After this tragedy he switches to being the full-time instructor. When a Daemonite called S'ryn puts Marc's girlfriend Major Diane LaSalle into a coma, he deserts StormWatch to track her down, breaking Cabal agent Taboo out of prison to help him on his quest. While he eventually catches his prey and revives Diane, he and Taboo become lovers, and both become fugitives.

Subsequent to this, Marc discovers he had fathered twin children—a girl named Jodi Morinaka and a boy known only as Aries—by an old girlfriend from Japan. He learns of Jodi when she tracks him down after her mother's death. Like her father, Jodi's alien genes give her superhuman powers, and she takes the identity of Crimson so she can adventure with him. Backlash and Taboo arrange a pardon for their crimes in return for working for the United States' Department of Paranormal Science Investigations (PSI). Taboo's initial approach by the government results in a multi-super-powers fight throughout the house as several of the FBI agents lose their cool and employ violence. "Backlash" #21. In the same issue, Marc is dealing with emotions over Ares, he has recently learned not only that he has a son, but Ares is a cold-blooded, brain-washed assassin.

Marc makes friends with the animal-faced adventurer Dingo, who helps him out on more than one case. It is around this point Marc finally learns of his Kherubim ancestry—for reasons best known to himself, Ferrian had never told Marc. Marc is placed in charge of forming a team of superpowered operatives codenamed Wildcore for Department PSI.

Around this time Marc battles several of Dingo's associates, a race of animal-people that call themselves The Kindred.

In an issue of WILDC.A.T.s, the long-lived Savant attempts to recruit Marc for a new version of the team. He turns her down.

He works with Wildcore until most of this team are killed trying to stop a breakout at the Purgatory Max facility, as seen in the Gen-Active series. Marc survives thanks to the assistance of former DV8 member Evo who had been imprisoned for the murder of an NYPD officer. Marc loses a leg, has it replaced with an artificial one and returns to duty.

According to his daughter, Marc gives up the name "Backlash"; seeking, as she put it, to keep it in the family, Jodi uses it herself. Marc Slayton appears in Sleeper as a plainclothes agent of Department PSI with the rank of Commander.

In a back-up story that ran through four different Wildstorm titles, Marc was featured in a story called "Slayton: Gauntlet" in which he must escape from the mutated experiments held within International Operations Research and Containment Facility #42 in New Mexico. Throughout the story, Slayton is required to use his powers in order to survive, revealing that he retains the ability to turn into mist, as well as use his psi-whips. At the conclusion of the arc, Marc laments not having his costume and plans to seek out some of his former Team 7 cohorts, indicating a possible return to his more active role in the Wildstorm universe.

In Wild C.A.T.S issue 14, Lynch approaches the Wild C.A.T.S. with Team 7 in order to team up with them and face the god-like Tao, who is consolidating his power in hopes of reigning over the post-Armageddon world. While severely outmatched, the C.A.T.S. and Team 7 get assistance from Max Faraday, who downloaded God-like abilities from the internet and has saved scores of people in pocket universes that he's kept hidden from super heroes and villains alike. However, Tao wants Max's power, and lures him into battle, leaving Slayton and other Team 7 members to battle Tao's cronies. Slayton is seen leaping into battle and using his psi-whips to lift and incapacitate Blackwolf while Ladytron blasts him with a sonic beam from her mouth.

In the 2017 reboot of the WildStorm line, The Wild Storm, Marc Slayton is one of the members of Project: Thunderbook, an Internal Operations project run by former director John Lynch. In Thunderbook, Slayton and others had their DNA spliced with that of alien(Kherubim/Khera) descent, giving him extraordinary powers as a part of his 'implant.'

However, after Lynch was forced out of I/O, Project: Thunderbook was shut down, and the subjects given cover identities. Over the years, Slayton's implant became sentient and aware of its descent, allying itself with the Khera on earth. As the implant began to communicate with Slayton, his mental state began to deteriorate, as he began to murder people to feed the implant, which he calls the "Carer," a misheard version of Khera.

When I/O began to look into Project: Thunderbook, John Lynch began to track down the previous subjects, starting with Slayton. However, when Lynch found out about his loss of sanity, Slayton attempted to murder him. After Lynch escaped, Slayton began to hunt him down, along with other Gen:Active subjects created by I/O rival Skywatch's Dr. Helspont after the deterioration of Thunderbook. Along the way, Slayton murdered one other Skywatch implanted agent, and attempted to attack Midnighter and Apollo, but fled as soon as it was clear he could not take them. Slayton eventually found Lynch after he warned all of the other members of Thunderbook, but was convinced by him to instead go to New York to take out I/O, as it would be beneficial to the 'Carer.'
