The 1990s were a heyday for the X-Men. Several teams were spread across multiple titles as well as several solo books. It was an influential time for Marvel's mutants, producing some key characters and storylines that still reverberate through comics today.

The '90s were also a time of ridiculous characters that certainly didn't stand the test of time. In some cases, these characters lasted only a few issues of a comic before all but disappearing. Some of these characters were so bad that they could only have been created in the '90s. Thankfully, fans don't see them much these days, although they do occasionally pop up.

10 Cyber

Primarily going up against Wolverine, Cyber is a quintessential '90s villain. A mercenary mutant with a psionic ability to track brainwave patterns, Cyber had his skin bonded with a thin layer of adamantium. This made him virtually invulnerable to any attack.

Additionally, he had adamantium talons in his fingers, each one loaded with powerful hallucinogens or poisons specifically designed to harm Wolverine. Though he was eventually resurrected, Cyber's appearances were infrequent and quickly came to an end when he was gutted by beetles, leaving only the adamantium behind.

9 Spyne

Spyne's mutant powers are pretty straight forward. He has a reptilian body that comes with fangs, claws, and a tail, and he loves to use them to eat his opponents. Really, fights for him are more about sizing up his meals than coming out on top.

Spyne served as a member of the Dark Riders under the command of Genesis, attacking Wolverine and Cannonball. Spyne rarely showed up during his short '90s run and was killed by Wolverine in combat. He has been briefly resurrected since, but only a couple of times and only for short periods.

8 Maggott

Maggott wins two awards: One for being an extremely short-lived '90s character and another for having one of the worst mutations in history. Instead of a traditional abdomen like most people have, Maggott has two large maggot-like creatures that crawl out of his gut and can eat pretty much anything.

It's an odd mutation that is simultaneously impressive and borderline useless. His main run was in the mid-1990s, though he quickly disappeared. Maggott was briefly a member of the X-Men, then Generation X. He disappeared from the second team after one issue.

7 Chamber

When it comes to losing the mutant ability lottery, Chamber takes the cake. A significant percentage of his torso is gone, replaced by a furnace of psionic energy that can produce powerful blasts. Chamber was part of the original line up of the '90s mutant team, Generation X, alongside several other mutants who didn't fit in other books.

While Chamber has had limited use since the '90s, his best run was short and sweet. He might have been around for more some other forgotten characters, but his run wasn't impactful or particularly memorable.

6 Skin

Another member of Generation X, Skin had the mutant ability to stretch and manipulate his skin, but only his skin. The rest of his body stayed relatively the same. His time in comics was relatively short as he was crucified on the front lawn of the X-Mansion alongside other young mutants.

Skin's power was a weird one, though not necessarily the weirdest. His time with Generation X was short and uneventful excluding his death. Most fans never connected with him so he ended up being a set-piece sacrificed to push a larger story.

5 Forearm

Forearm is about as '90s of a character as you're gonna find. His name is Forearm and he has four arms. Get it? Forearm also has enhanced strength, endurance, and stamina, abilities directly related to Forearm having four arms. To be clear, his name is Forearm and he has four arms.

As a member of the Mutant Liberation Front, he came into conflict with Cable and his X-Force team. Despite his strength, he wasn't particularly useful in combat and usually got his butt handed to him by Warpath on the rare occasion he actually appeared. After his brief time in the pages of X-Force, he largely vanished from comics.

4 Random

Yet another on the nose name, Random's body was made from morphing protoplasm. This allowed him to change his shape into virtually anything, including making his arms into weapons that fire-hardened protoplasm projectiles.

Random was a persona created by the mutant, a character that looked like a grizzled bounty hunter. He bears more than a little resemblance to Duke Nukem. Random's main run was with X-Factor in the '90s but he quickly faded away. Since then, he has had sporadic appearances in other comics though nothing close to what he had back in the day.

3 Joseph

At one point in the 1990s, a younger Magneto reappeared and ready to fight on the side of the X-Men. Naturally, Joseph turned out to actually be a clone of Magneto because that is Marvel's go-to move, particularly in the '90s.

Joseph had similar powers to Magneto, though he lacked the experience, training and control the real Master of Magnetism had. Inevitably, he turned evil and tried to blame the real Magneto for his crimes. Marvel continued to use him sporadically over the years but he never reached the same height as when people thought he was Magneto.

2 Synch

One more member of Generation X appears, proving that it was the quintessential X-team of the 1990s. Synch had the ability to duplicate the effect of any superpowered being near him. In some cases, he could full on mimic the power itself.

It was actually quite an impressive power with huge potential, but he never got the chance to explore that fully. Synch was killed when Emma Frost, who was the headmistress of the school the team worked out of, was attacked by her sister. He disappeared from the comics quite quickly, though he was one of many mutants resurrected by Selene using the Transmode Virus.

1 Adam X

This character was the X-Men equivalent of Poochie. He was introduced in X-Force, then rarely used after that over the next few years. Created by Fabian Nicieza, the intention was reputedly to make him another Summers brother, the son of Katherine Summers and Shi'Ar Emperor D'Ken.

If true, that story never had the chance to play out, which may have been for the best. Adam X was disgustingly extreme, from his backward hat to his ridiculous hair. Like Poochie, he should probably have died while returning to his home planet.
