10 Best X-Men Villains Introduced Since 2000

From Magneto to Apocalypse, the X-Men have some of the coolest villains in comic lore. But the franchise didn’t just stop introducing evil-doers in the ’90s. Here are the best X-Men villains introduced in the last twenty-six years, what they can do, and what makes them so interesting.

Death, the First Horseman

Debuted in 2019’s Marvel Comics #1000, Created by Jonathan Hickman and Dustin Weaver

Throughout X-Men history, the villainous Apocalypse has transformed heroes and villains into his Horsemen, empowering them as the latest War, Pestilence, Famine and Death. However, in 2019 X-Men fans learned these aren’t titles – they’re the names of his children.

Apocalypse’s kids were locked in a dimension of demons for thousands of years, but eventually returned to Earth as conquerors, clashing with Storm and her army of Martian mutants.

Death wears an Anubis mask to cover his eyes, which have the mutant ability to disintegrate anything he sees. He battles with a scythe and has such an extreme sense of honor that he killed his own sister when she targeted Storm outside the rules of combat.

Death may be a killer, but he’s one of X-Men‘s most suave characters – a charmer who has clear romantic interest in Storm, and would rather dance than fight.

Mother Righteous, aka Rebecca Essex

Debuted in 2022’s Legion of X #1, created by Simon Spurrier and Jamie McKelvie

Mother Righteous is a powerful magic-user who loves to do favors. The only downside is that once you thank her, you’re in her power, and can be used as fuel for more ambitious spells. Mother Righteous’ magic grants her teleportation, energy blasts, resurrection and more, but she’s only as strong as the debts she can invoke.

She’s also one of four clones created by the Victorian villain Nathaniel Essex – and the only one based on his wife – but more on that shortly…

The Chairman

Redesigned in 2024’s X-Men Volume 7 #1 by Jed MacKay and Ryan Stegman

Technically, this character was ‘introduced’ in 1963 as a founding X-Men, but he only turned evil recently. During X-Men‘s Krakoan Era, Beast took leadership of X-Force and was quickly corrupted by the power, sliding into true, unforgivable evil.

Beast was presumed dead and replaced by a younger, still-heroic clone, but has since resurfaced as the mutant supremacist villain known as the Chairman. Beast’s consciousness is now housed in an artificial body with white fur, as he works towards creating an ‘X-Virus’ which will kill the majority of humanity, and turn the survivors into mutants.

7

John Sublime and the U-Men

Debuted in 2001’s New X-Men Annual #2001, Created by Barry Windsor-Smith

John Sublime is one of X-Men’s creepiest villains – a sentient bacteria that has survived billions of years by infecting host after host. Sublime wants mutants wiped out so he can become the planet’s deadliest lifeform, and will use any means to do it, whether that means secretly infecting one of the X-Men or a convenient business magnate.

One of Sublime’s tactics was to create the cult of the U-Men. This semi-religious group surgically graft mutant parts onto their bodies, hoping to steal their powers. The U-Men started out as useful pawns for Sublime, but the cult has since spread and taken on a life of its own.

Solem of the Silver Skin

Debuted in 2020’s Wolverine #6, Created by Jonathan Hickman, Pepe Larraz and Benjamin Percy

Solem is a hedonistic mutant with skin made of pure adamantium. Utterly unbreakable, he’s one of the world’s greatest fighters, thieves and flirts, often getting into trouble because of who he seduces as much as what he steals.

Solem is an outcast member of the ancient mutant society of Arakko, and struck up a friendly rivalry with Wolverine when the Arakki came into conflict with the X-Men.

5

Tarn the Uncaring

Debuted in 2020’s Hellions #6, Created by Zeb Wells and Carmen Carnero

Tarn is a terrifying villain with the powers of a ‘genomic mage’ – he can rewrite a person’s genetic code just by looking at them. Tarn is the leader of the Locus Vile – ultra-powerful mutants who have been warped physically and psychologically to serve him – and may be Marvel’s greatest sadist, taking immense pleasure in hurting and defiling others.

While he was killed by Magneto in gladiatorial combat, Resurrection of Magneto confirms that his spirit is clinging on to existence, looking for a way to return.

4

Danger, the Living Danger Room

Debuted in 2005’s Astonishing X-Men #9, Created by Joss Whedon and John Cassaday

Danger is the X-Men’s iconic ‘Danger Room’ come to life. It turns out Xavier included alien tech in his students’ training facility, leading its core AI to develop sentience and eventually a physical form.

Danger hates the X-Men for imprisoning her, and years of experience have made her the expert at taking them down. Sadly for her, her core programming stops her actually killing Xavier’s students.

Danger has been both ally and enemy to the X-Men ever since she took physical form. Her hard-light holographic abilities and techno-morphing allow her to take pretty much any shape.

3

The Children of the Vault

Debuted in 2006’s X-Men #188, Created by Mike Carey and Chris Bachalo

The Children of the Vault are humanity’s attempt to compete with mutants – experimental cyborg superhumans raised in ‘The Vault’ – a time prison where centuries can pass inside while only hours pass in the real world.

Each of the Children of the Vault is for a specific purpose, and they’re programmed to want to scour all other superhumans from the face of the Earth. Each time the X-Men face the Children, thousands of years have passed for the villains, leading to new powers and vast changes in their identities and philosophy.

2

Cassandra Nova

Debuted in 2001’s New X-Men #114, Created by Grant Morrison and Frank Quitely

An alien evil known as a ‘Mummundrai’ attached to Charles Xavier in the womb, using his DNA to grow a ‘twin sister’ named Cassandra Nova. Cassandra may behave like a human, but she’s actually an unknowable advanced lifeform that instinctively wants mutants dead because it sees them as competition.

She’s the biggest killer of mutants in Marvel lore, having orchestrated the Genoshan genocide, slaughtering sixteen million mutants in one fell swoop.

Cassandra Nova will take your deepest trauma and force you to relive it a thousand times a second. She was played by Emma Corrin in Deadpool and Wolverine, but with a lot of her stranger edges sanded off.

Enigma, the Nathaniel Essex AI

Debuted in 2022’s Immortal X-Men #8, Created by Kieron Gillen, Michele Bandini, Al Ewing and Javier Rodríguez

In one of the X-Men franchise’s best twists, the Krakoan Era revealed that classic villain Mister Sinister is just one of four clones created by Victorian eugenicist Nathaniel Essex. Essex planned to ascend to godhood as a ‘Dominion’ – a cosmic intelligence that exists outside linear time.

To enact this plan, Essex programmed Mister Sinister, Doctor Stasis, Orbis Stellaris and Mother Righteous to all try and achieve godhood in a different way. What none of them knew was that each of their successes was feeding back into a hidden AI known as Enigma. When Enigma finally had enough information, it became a god, and began rewriting the timestream to wipe out the X-Men.

Enigma is witty, sly, arrogant and easily the most powerful villain in X-Men history. Thanks to the Phoenix Force, Enigma was torn to pieces, suffering eternally across time and space. Of course, this is comics, and it’s only a matter of time until he returns.
