As the Eternals event slowly creeps closer, many of the strongest mutants are getting ready to face off against the best that the Avengers and Eternals have to offer.
But, although the X-Men are known for a wide ensemble cast with extraordinary powers and incredible skills, there are some mutants that just don't fit the bill. If only because their mutations are a little underwhelming or their interests tend to lead them away from fights, they tend to be some of the weaker mutants the X-Men have in their ranks.
Beast
Though incredibly intelligent, the X-Men's Beast isn't really known for his prowess in battle. Though his mutation grants him greater agility, as well as claws and fangs, he's more the type to spend hours in a lab than hours in the field. After all, he is an intelligence operative now.
But, given that many of the original X-Men weren't particularly powerful, Beast isn't exactly a break from the norm. His broad frame and flexibility give him an edge in a fight, but it isn't anything compared to healing powers or reality warping.
Nightcrawler
More known for his excellent design and superb superhero costume than anything, Nightcrawler tends to be ed more for form than function. Though he can teleport, he has a lot of problems with his teleportation that other porters really don't.
There's the sulfuric smell he leaves behind, and he has difficulty carrying multiple people at once or heavy weights across space. His porting is also limited, as he can't make particularly great leaps in space. Often, he has to make little jumps multiple times, which slows down his effectiveness in combat. His short range really does make him a helpful fighter, but outside of that, it doesn't compare to other teleporters like Pixie and Blink.
Thunderbird
Most ed for being a part of one of the best X-Men comic book issues of the 1970s, Thunderbird is regarded more for his attitude and his self-sacrificial tendencies than for his fighting skills. Though he has heightened agility, strength, and durability, he isn't really a mutant that has any semblance of a greater powerset.
Even on the second X-Men team, he was overshadowed by Wolverine, who had the same powers with added regeneration and metal claws. It made Thunderbird seem repetitive, which is part of why he was shelved for decades. While he's making moves today and earning his own solo book, he is still one of the weaker X-Men.
Danielle Moonstar
A mutant with a strange assortment of powers, Dani Moonstar is one of many X-Men mutants who doesn't really go by her codename often. Still, "Mirage" was a good name, as Moonstar has the power to dip into someone's mind and present them with images of their greatest fear or their biggest want.
While she later developed additional skills as both a Valkyrie and a mutant with the ability to communicate with animals, she mostly resorts to using a bow and arrow and her own inherent fighting skills. It makes her an excellent 1-on-1 fighter, but her limited powers mean she can't often do much outside of the leadership position she thrives in.
Jubilee
Fireworks and sparkles. It's a lot of fun on the Fourth of July, but it makes for a pretty weak mutant power. Unfortunately for the X-Man Jubilee, that's about all her X-gene granted her. There's a reason she thrived during the few years she spent as a vampire; it gave her something to do.
What many people don't know is that Jubilee has led comic teams in the past, proving that she can do more than light shows as long as she puts her mind to it. Still, with powers that turn her into the equivalent of a human sparkler, there aren't many reasons for fans to get excited about her powerset.
Glob
A pink gelatinous creature with a fully functional skeletal system that shows through the translucent gel, Glob Herman is a terrifying sight, but that doesn't stop him from being one of the weakest mutant heroes. Though his bizarre skin makes him extra durable, he's still one of the strangest superheroes of all time.
Glob usually tries to make himself useful in fights by setting his skin on fire, as the weird texture makes him extra flammable without causing him any sub-surface damage. Still, when there are mutants that can control or produce fire on a whim, having a big pink mess running around on fire isn't exactly an advantage in a fight.
Kylun
A mutant introduced in Excalibur, Kylun is a legendary figure who traveled across the multiverse as a sword-swinging do-gooder desperate to defeat the evil lord Necrom. Though he seems a character more fit for King Arthur than X-Men, Kylun is actually a mutant. Unfortunately, his powers don't do much for him.
While his mutation gave him his cat-like appearance, it also gave him a single mutant power that one could never really predict: It lets him mimic any sound perfectly. Be it a train engine, a voice, or a buzz saw, Kylun can replicate any sound on command. It just isn't very useful.
Angel
While Angel developed some serious powers later on in his life, his original powerset was rather lacking. Though only comic book fans know this about Angel, his original power was simply having two feathery white wings that sprouted from his back. They gave him the ability to fly. That's all.
When there are mutants who can fly and shoot fire, fly and move at superspeed, and fly and use telepathy or telekinesis, it's somewhat pathetic to only be able to fly. It's even worse that he has to rely on wings in the process, since many mutants have flight without having to worry about two extra appendages in a fight. It also meant he couldn't do much in early X-Men fights.
Beak
Somehow even worse than Angel, Beak is utterly useless in a fight. Though he has a great personality and is great at making friends, he isn't much of a use in any other context. With a mutation that makes him look like a freshly born chicken, Beak can do very little besides waddle around beside his fellow mutants.
Though he has claws and talons, they don't really help as much as they should given that he's often up against genuine supervillains. His long-ranged sight also isn't much of a help in a world where guns and scopes exist. Really, there isn't much Beak can do in general, and it's always somewhat sad to see him in a fight.
Wraith
It's hard to be much worse than Beak, but Wraith manages it. His only power is having the ability to make his own skin transparent, thanks to a minor invisibility field. While he can transfer the field to other people and objects, it really isn't much of a use, and he even has to touch the object to do it.
Up against villains like Magneto and the Purifiers, it's a miracle Wraith lasted as long as he did. After all, he doesn't even have fighting skills to back him up as some other mutants do. Somehow, M-Day was probably the best thing that ever happened to Wraith. In fact, it's possible he may not want to get his powers back at all.
