For a team that started with five members in 1963, the X-Men have grown by leaps and bounds in the decades that followed. Marvel's team of merry mutants have had some of the most powerful and most popular characters in all of comics, from Cyclops and Jean Grey to Wolverine and Storm.

But with so many members coming and going through the halls of Xavier's School for Gifted Youngsters, there are more than a few teammates who maybe shouldn't have been on the team. For some of them, their powers just aren't that impressive, but for others, it's an issue of their past actions or what their rather impressive powers can do to the other X-Men. Still, there these mutants were, or are, standing alongside the X-Men fighting to make the Marvel Universe better for everyone.

10 Beak

Barnell Bohusk, aka Beak, is one of the stranger looking X-Men. As his name suggests, Beak has the characteristics of a bird, but he only has feathers on his arms, making him look not unlike a baby bird. While the X-Men have never been afraid to have teenage mutants on the team, Beak's powers just don't cut it for the kinds of things Professor X's crew needs to deal with on a regular basis. Along with flying, Beak has sharp talons which can cause a good amount of damage, but they're no adamantium claws. Even more, Beak is just too nice to be a superhero. He doesn't have the fighting edge that the job calls for.

9 Magneto

Magneto

As the Master of Magnetism, Magneto is more than powerful enough to be one of the X-Men. In reality, he is more powerful than the vast majority of mutants who have been on the team, but it takes more than just power to be an X-Men, it takes empathy, which is something Magneto is severely low on.

Over the years, Magneto has gone from being an enemy of the X-Men to a member of the team and back again multiple times. His overall goal to rid the world of humans puts Magneto at odds with the teachings of Charles Xavier, and while everyone deserves second chances, Magneto is easily on his tenth or eleventh by this point. Sooner or later, he's bound to go evil again.

8 Wraith

Hector Rendoza wasn't a member of the X-Men for long, but he was a member. Calling himself Wraith, Hector was psychically trained by Jean Grey to quickly master his invisibility powers so that he could help her save the other X-Men who had been taken captive by Magneto on the island of Genosha. But aside from the occasional espionage mission, Wraith just isn't that useful and in a fight, he was more of a liability than a help. Sadly, or maybe luckily, Wraith lost his powers on M-Day and hasn't been seen since.

7 Wing

Not every mutant power can be as cool as turning into organic metal like Colossus. Sometimes you end up like Jazz, whose whole power was having blue skin. Somewhere between those two options is Wing, a young mutant who could fly and never should have been a member of the X-Men.

When the alien warrior Ord attacked the X-Men, he used the mutant cure on Wing, taking away his powers. Wing loved nothing more than flying, and without his powers, he entered a deep depression that ended with his suicide when he tried one last time to fly and fell to his death.

6 Stacy X

X-Men Stacy X

 

When it comes to mutant powers, Stacy X had some good ones. Along with her snake-like skin that worked as a form of light armor, Stacy X could change a person's metabolism with a touch, making them heal at an accelerated rate or get a much-needed rush of adrenaline during a fight. Or she could use her powers to do the exact opposite, making her foes become instantly exhausted.

What kept Stacy X from being worthy of joining the X-Men was her mental attitude. Stacy X chose to leave the team when she came to the conclusion that Archangel was never going to fall in love with her. If the only reason someone is on the X-Men is to hook up, they're there for all the wrong reasons.

5 Jubilee

Jubilee

Jubilee joined the X-Men by accident, following some of the members through a portal and ending up in the Australian Outback where the team was hiding out at the time. She soon became Wolverine's sidekick who just happened to be similarly dressed like Batman's sidekick, Robin.

In some ways, Jubilee was Wolverine's second sidekick, with Kitty Pryde acting as the first one. And just like Jason Todd, the second Robin, Jubilee didn't quite work in the role. Adding to the problems was that Jubilee's power to create colorful explosions that didn't do much damage meant she wasn't much help in a fight.

4 Glob Herman

Glob Herman's unique mutant body surrounded by the X-Men

With a body made up of living wax, Glob Herman can make like a candle and set himself on fire. He can then fling his melting flesh at people, which is more gross than useful. Glob also has superhuman strength, but it is on the lower end of that kind of power, meaning that he can lift more than a powerless weightlifter, but not much more.

Glob was one of the students at the Xavier School for Gifted Youngsters that started a riot on the campus under the leadership of Quintavius Quire. That action alone should have led to his dismissal from the school, but instead, he was allowed to join the team.

3 Rogue

X-Men Rogue

 

Rogue is undeniably one of the strongest and most loved Marvel characters, and with good reason, Her power - the ability to take anyone's powers and memories with a touch - is very cool, and the downside of that power - she can't control it so she can never actually touch anyone - makes her a truly tragic character.

But that power also makes her a serious liability in many ways. Rogue keeps most of her body covered, but in a battle, clothes tend to get torn up, and an accidental touch could lead to one of her fellow teammates being taken out of the fight. While that situation has never come to pass, it seems like it is just a matter of time.

2 Maggot

X-Men Maggott

 

As his name suggests, Maggott's power is kind of gross. Maggott has two techno-organic slugs that act as his digestive system, meaning that instead of eating a nice peanut butter and jelly sandwich like everyone else, Maggott feeds these two creatures that are growing out of his stomach.

The slugs can eat anything, from that peanut butter and jelly sandwich to a rusty steel girder, which can have its uses, but unless the X-Men are fine with having a member eat their enemies, Maggott isn't that helpful in a battle.

1 Angel

X-Men Founder Angel

For a team with so many members with so many amazing powers, the X-Men have had a fair amount of teammates whose only power was flying. Warren Worthington III was the first one of those. A founding member of the X-Men, Warren went by the name Angel. Angel was clearly the weakest member of the team, but that never stopped him from doing everything he could to help, and that's what led to his death.

While a member of the original X-Factor, Angel's wings were badly damaged, leading to them becoming infected. To save his life, Angel's wings had to be amputated. Angel then tried to kill himself but was stopped by the evil Apocolypse, who turned him into Archangel, one of his Four Horsemen. Had Angel never joined the X-Men, his life would likely have been a lot happier.
