Updated on March 10, 2025 by Alfredo Robelo: While most comic book rosters have an expansive cast of characters, the X-Men are notorious for having a huge number of incredibly memorable ones. We've updated this article with even more incredible characters, without necessarily ranking them in any way.
13 Beast
Real Name
Hank McCoy
First Appearance
The X-Men #1 (September 1963)
Hank McCoy, better known as Beast, is one of the X-Men’s most beloved characters, combining brilliant intellect with raw physical power. As a founding member of the team, Beast’s blue-furred appearance and superhuman strength often conceal his gentle and introspective nature. His scientific genius has been a cornerstone of the X-Men’s success, contributing to everything from technological advancements to medical breakthroughs.
Beyond his brains and brawn, Beast’s character explores themes of identity and acceptance. His struggles with his mutant appearance make him a relatable figure for anyone who has ever felt like an outsider. Whether serving as a diplomat or fighting alongside his teammates, Beast is a vital part of the X-Men legacy.
12 Apocalypse
Real Name
En Sabah Nur
First Appearance
X-Factor #5 (June 1986)
As one of the most iconic villains in the X-Men universe, Apocalypse, also known as En Sabah Nur, represents the ultimate challenge to mutantkind. Believed to be the first mutant, Apocalypse possesses godlike powers, including super strength, telekinesis, and the ability to reshape his body. His Darwinian philosophy—survival of the fittest—puts him at odds with the X-Men’s vision of coexistence.
Apocalypse’s presence often marks some of the X-Men’s most harrowing storylines, such as the Age of Apocalypse saga. His complex character blends ruthlessness with moments of tragic depth, exploring themes of power, destiny, and the cost of progress. Apocalypse’s indomitable will and towering presence make him an unforgettable figure in X-Men lore.
11 Legion
Real Name
David Haller
First Appearance
The New Mutants #25 (March 1985)
David Haller, known as Legion, is one of the most complex and powerful characters in the X-Men universe. As the son of Charles Xavier, Legion’s immense psychic abilities include telekinesis, time manipulation, and reality warping. However, his fractured psyche, housing multiple personalities—each with its own power—makes him as much a danger as an asset to the X-Men.

Posts 1Legion’s unpredictable nature has led to some of the most intriguing stories in mutant history, including the creation of alternate timelines like the Age of Apocalypse. His struggles with mental illness and his desire to live up to his father’s ideals make him a compelling, deeply human character. Few mutants wield the power or narrative complexity of Legion.
10 Mystique
Real Name
Raven Darkhölme
First Appearance
Ms. Marvel #16 (May 1978)
Mystique is a unique-looking mutant with a design that makes her stand out even among a group of people who are persecuted for standing out. She possesses the ability to shapeshift and has the wit to make that ability very dangerous. She adds an edge to the stories she's in, as her ability has the potential to lead to clever reveals.
In the vast expanse of the X-Men storylines, she's been a villain, an anti-hero, Sherlock Holmes, Rogue's adoptive mother, Nightcrawler's biological father, and a leading character in queer representation. This range is what makes her character so interesting to watch: she has an almost endless ability to adapt to whatever story she's in.
9 Phoenix
Real Name
Jean Grey
First Appearance
The X-Men #1 (September 1963)
An extraordinarily powerful, omega-level mutant with psionic powers, Jean Grey, has even more raw power than her mentor, Professor X. Since she's been with the team since its inception, she's an important person in the lives of most of the X-Men, taking on the role of mentor and protector. This is especially true of her romance with Cyclops, which is one of the most beloved relationships in the series.
The Dark Phoenix Saga is also one of the most iconic character arcs in all of X-Men, and Jean Grey is at the center of it, struggling with her relationship with the Phoenix Force (a cosmic force that basically just makes her even more powerful). As a character, she pushes being a mutant to the extreme, and her struggles with that give the entire series' conflict of mutants versus non-mutants a personal depth.
8 Rogue
Real Name
Anne Marie (LeBeau)
First Appearance
Avengers Annual #10 (1981)
Part of what makes X-Men so interesting compared to other superhero stories is the role the "mutations" play, with characters often struggling with aspects of their abilities, even finding them to be more a curse than a blessing. And no character demonstrates this better than Rogue. Her ability is activated by skin-to-skin contact, allowing her to take others' abilities, attributes, memories, and even life force, but it's initially uncontrollable and leaves her feeling isolated.

PostsThis internal struggle complicates narratives of what mutation and freedom mean in the X-Men world. All while her ability lets her act as a very interesting and dangerous agent when it comes to fighting literally anyone.
7 Gambit
Real Name
Remy LeBeau
First Appearance
The Uncanny X-Men Annual #14 (August 1990)
A charming smooth-talker with the charm of a con man, Gambit is a former thief who gives us everything that we love about rogue-like characters. He has the ability to generate and manipulate kinetic energy, a gift he channels with a sense of flair, most notably using playing cards to channel his power.
His evolution throughout his run, on both sides of the conflict and from a ladies' man to Rogue's husband, makes him a dynamic character that we can't help but keep rooting for.
6 Nightcrawler
Real Name
Kurt Wagner
First Appearance
Giant X-Men #1 (1975)
A Catholic with the appearance of a demon, Nightcrawler is a man of apparent contradictions, but he has a very lighthearted personality, always joking around and performing for the people around him. He adds much-needed levity to any team he's a part of, especially in contrast to characters like Wolverine.
This doesn't mean that he'd play pranks at the expense of others; Nightcrawler is also in tune with people, and he's good at comforting them. This makes him a good character to bridge gaps. The more we sympathize with his kind nature, and the more his appearance often puts him in danger, the more we understand the stakes of the conflict.
5 Cyclops
Real Name
Scott Summers
First Appearance
The X-Men #1 (September 1963)
Despite having lasers shoot from his eyes whenever he isn't using his protective glasses, Cyclops has remained one of the most down-to-earth members of the X-Men, which makes him endlessly relatable. His introspective nature means that we see him struggle to grow into his role as a guide and leader for other mutants, making him a touchstone for what it means to be an X-Men.

4 Magneto
Real Name
Erik Lehnsherr
First Appearance
The X-Men #1 (September 1963)
Magneto is an engaging antagonist who's clever enough to use his ability to control magnetic fields to devastating effect. But what makes him a truly iconic character is that he's well-rounded, and the reasons behind his "villainy" are well thought out, even lauded by many in-universe. He represents both the righteous anger against injustice and the dark depths of seeking revenge.
This viewpoint puts him in conflict with Professor X, and the tension between their ideas about how mutants should react to their oppression shapes much of the universe.
