The original Marauders team included mutant warriors and assassins employed by the X-Men's enemy Mister Sinister, a mad scientist villain often intent on creating a perfect race of superhumans.

[citation needed] During "Mutant Massacre," three Marauders are killed: Blockbuster in The Mighty Thor #374, Riptide in The Uncanny X-Men #211, and Prism in X-Factor #10.

[citation needed] X-Men #200 (2007) featured the original Marauders team with several new members, including Omega Sentinel (possessed by Malice), Lady Mastermind, Sunfire, Gambit, and Mystique.

3) #48, a new version of the Marauders appeared whose members included: Arclight, Blockbuster, Harpoon, Prism, Vanisher, and Chimera (serving as the new leader).

[14][15][16] Screen Rant highlighted that "the Marauders are functionally the Krakoan navy in the Dawn of X era and are an extension of both the X-Men and the high stakes machinations of the Hellfire Club".

[20][21][22] Screen Rant commented that in the first volume the Marauders were "tasked with protecting the interests of the Hellfire Trading Company's black-market and rescuing mutant refugees feeling from unfriendly nations, returning them to safety on Krakoa.

During this time, Essex meets the Egyptian terrorist and cult leader En Sabah Nur, who might be the earliest example of a mutant on Earth, a person born with an X-gene that grants them superhuman powers and/or traits.

Like Essex, En Sabah Nur (who will later be known as Apocalypse) believes in "survival of the fittest", though their methods and ultimate goals differ.

Sabretooth, working as a mercenary, is hired to find the truth about the "White Devil" and his connection to reports of missing people, as well as the rumors of "monster men" appearing.

Since Jean Grey is already being mentored and watched over by the powerful telepath Professor Charles Xavier, Sinister spends years focusing much of his efforts on manipulating Scott Summers.

To aid in this, Sinister brings the orphaned Scott to the Essex State Home for Foundlings in Nebraska, an orphanage he secretly runs and uses to monitor and experiment on mutant children.

When Scott and Jean become founding members of Xavier's counter-terrorist strike force, the X-Men, Sinister decides to obtain fresh DNA samples from all of them.

He is further angered when his studies reveal that several Morlocks bear signs of genetic manipulation based on his own research (due to the fact that many of them were experimented on by Dark Beast).

The Marauders dismiss Gambit and begin their slaughter, causing the "Mutant Massacre" event, a series of battles that include the X-Men, X-Factor, and other heroes such as Thor.

[37] Following the "Mutant Massacre", the remaining Marauders attack the X-Men's base at the Xavier School for Gifted Youngsters (also known as the X-Mansion) in Westchester, New York.

Transformed into the demonically powered "Goblyn Queen," Madelyne is at the heart of the "Inferno" crossover as Hell-bound forces cross into Earth's dimensions.

They seemingly kill the mutant teleporter Gateway and the time traveler Cable (a grown-up version of Nathan Summers), but both later turn up alive.

[47] Da'o Coy Manh, the half-sister of the mutant known as Karma, forms a new incarnation of the Marauders in order to take revenge on her father.

[51] Magneto later unleashes his loyal Marauder clones against the international intelligence agency S.H.I.E.L.D., using them as a distraction while he destroys much of the organization's collected data on mutants.

[44] Magneto kills the Sabretooth clone when he realizes its feral nature and healing abilities make it resistant to his mental loyalty programming.

[52] In the 2019 Dawn of X event, Xavier and Magneto work with the X-Men, as well as many allies and former enemies, to create a new mutant nation and sanctuary on the living island of Krakoa.

To aid these mutants who cannot access the gates, Kitty Pryde forms a new group she calls the Marauders, recruiting her now reformed enemy Pyro as well as former teammates Storm, Iceman, and Bishop.

While Sinister is left alone due to now being a member of Krakoa's ruling Quiet Council, Scalphunter is confronted by Morlocks on the island who inform him it is the anniversary of the Mutant Massacre.

[54] For their first mission, the new Hellions go to Sinister's orphanage in order to confront the original Marauders, only to learn they have become zombie-like beings under the control of Madelyne Pryor.

Besides Chimera, this membership consisted of: Following the rebirth of the Multiverse in the aftermath of Secret Wars, Miss Sinister had made her presence known and assembled several mutants that became stranded from the Ultimate Marvel into the Prime Universe which she personally handpicked and trained to be killers.

[58] Miss Sinister later attempted to recruit the time-displaced Jean Grey to their cause by making sure she would find a necklace which unbeknownst to her, contained the essence of Malice.

[59] Shortly afterwards, the New Marauders were sent to attack Magneto, who had threatened Havok's plans[60] but the master of magnetism evaded them and escaped using his time platform.

[63] In the House of M reality, the Marauders are a covert ops group led by Callisto and consisting of Banshee, Black Tom Cassidy, Blob, Caliban, Mammomax, Sunder, and T-Rex.

[citation needed] In the Mutant X dimension, a group of thieves calling themselves the Marauders are made up of mostly X-Force and Generation X associates, such as an overweight Cannonball, Jubilee, Husk, Sunspot and Wolfsbane.

[citation needed] The Marauders appear in Wolverine and the X-Men, consisting of Mister Sinister, Arclight, Blockbuster, Harpoon, Multiple Man, Vertigo, and Archangel.
