The X-Men are famously a team of mutant heroes who fight for equality between humans and homo superior. However, while iconic like Cyclops, Iceman and Storm may be mutants, with incredible powers granted by the X-gene, the same can't be said for every member of the X-Men and their various spin-off teams. In fact, there are plenty of non-homo superior heroes who have earned hip on the X-Men.

Here are the 17 most powerful X-Men who aren't homo superior. While some may be considered 'mutants' of their own alien species, these are beings who don't possess the X-gene, and are considered aliens, human mutates, or even androids rather than what Marvel traditionally calls 'mutants.'

17 Juston Seyfert and His Sentinel/Tom Skylark and Rover

A Powerless Kid With a VERY Powerful Sidekick

Juston Seyfert and Tom Skylark have suspiciously similar stories - both human kids who discover and fix up a damaged Sentinel, winning the mutant-killing robot's respect and turning it into a force for good by reprogramming it for heroic ends. The big difference is in time period - Juston Seyfert exists in Marvel's present, whereas Skylark is a member of the future X-Men shown in Grant Morrison and Marc Silvestri's iconic New X-Men #151. Given the generational differences and the similarities between Juston's Sentinel and Tom's 'Rover,' fans have speculated that it's the same Sentinel, ed down from one human master to another.

In their original appearances, both Juston and Tom lack any powers of their own, though both have customized their Sentinels for maximum firepower. However, Juston Seyfert recently reappeared in Sentinels #4 (from Alex Paknadel and Justin Mason), having become a half-Sentinel cyborg.

16 Puck, aka Eugene Judd

Alpha Flight's Acrobatic Hero Also ed X-Force

Best known as a heroic member of Alpha Flight and longtime ally of mutantkind, Puck officially ed X-Force in Uncanny X-Force Volume 2, from Sam Humphries and Ron Garney. Puck is a human mutate (a non-mutant superhuman) who possesses enhanced speed, strength, reflexes and agility, as well as having his lifespan extended by supernatural means. An expert martial artist, Puck is an incredibly skilled fighter and accomplished adventurer.

15 Hepzibah

Starjammers' Alien Rebel Has Also Helped Out Mutantkind

A Mephitisoid alien, Hepzibah is a rebel hero and a key member of the Starjammers, often entering into conflict with the sprawling Shi'ar Empire. Hepzibah is the lover of Cyclops' father Corsair and often visits Earth alongside him, but has also served on the rosters of both the X-Men and X-Force, helping to fight the Reavers, Cyclops' evil brother Vulcan, and the Avengers (during the epic AvX event.) Compared to humans, Hepzibah possesses enhanced senses and increased speed and agility, and can also manipulate others via pheromones.

14 Broo

The King of the Brood Species Is a Former X-Men Student

A member of the predatory alien species known as the Brood, Broo is a 'mutant' of his species since he possesses higher-level intelligence that allows him to resist his predatory instincts. Discovered by the X-Men, Broo was recruited to the Jean Grey School for Higher Learning at a time when the school was actively expanding its non-homo superior student body. Broo's genius has helped the X-Men on many occasions, and he recently received a major power-up after eating a Brood King Egg, which gave him empathetic control over the vast majority of the Brood species.

13 Warbird, aka Ava'Dara Naganandini

The Shi'ar Warrior ed the X-Men With a Very Specific Mission

A warrior from the alien race known as the Shi'ar, Warbird is an expert warrior whose avian physiology gives her enhanced strength and stamina. Technically the bodyguard of Kid Gladiator - who ed the X-Men to study at Wolverine's Jean Grey School for Higher Learning - Warbird fought alongside the mutant faculty against enemies including the Marauders and Exodus. Warbird's time on Earth allowed her to explore her ion for art - something which was discouraged by Shi'ar culture.

12 Lockheed

Kitty Pryde's Pet Dragon Is an Alien Secret Agent

An alien being whose biology is similar to that of a small dragon, Lockheed has long been considered the pet of phasing mutant Kitty Pryde. A loyal friend, Lockheed was later revealed to have the same level of sentience as a human, working with the government group S.W.O.R.D. as an embedded agent. Lockheed can breathe powerful fire and has empathetic powers similar to telepathy. As well as fighting alongside the X-Men, Lockheed is a founding member of the Pet Avengers - a group of animal and animal-like heroes who have taken on Thanos in the past.

11 Mimic, aka Calvin Rankin

This Human Mutate Has the Original X-Men's Powers

Calvin Rankin's Mimic first gained powers after being exposed to his father's experiments, debuting in Stan Lee and Jack Kirby's X-Men #19 with the powers of the original five X-Men - Cyclops, Jean Grey, Iceman, Angel and the Beast. Mimic also has the ability to copy the powers of mutants in his vicinity, although in that case they aren't permanent.

While Mimic is technically powerful, he lacks confidence in his abilities and has never lived up to his potential. This is in contrast to the alternate-universe version of the hero fans know from the Exiles franchise. This Mimic is a version of Calvin who ed the X-Men after their early conflict, going on to become one of Earth's foremost heroes in his own reality.

10 Longshot

Mojoworld's Genetically Engineered Clone

Likely to be the most controversial entry on this list, Longshot was introduced as a genetically engineered humanoid created in the dimension known as Mojoworld. Originally believed to be a human mutate, it's since been revealed that Longshot is an altered clone of the mutant warrior Shatterstar, who is his biological son (the two exist in a time loop.) Longshot isn't a perfect clone of Shatterstar, raising the question of how much he can be considered a natural member of homo superior and how much he's a unique genetic entity created using Mojoworld's advanced science.

Whatever he is, Longshot is incredibly powerful. He has an advanced physique with strength, agility and regenerative powers far in excess of a human, and can see the past by performing psychometric readings on inanimate objects. However, his most useful ability is the power to manipulate probability in his favor, making him intensely 'lucky.' Longshot enhances his powers with throwing blades which, because of his luck, always hit their target.

9 Spiral, aka Rita Wayword

Mojoworld's Mystic Rebel/Enforcer

A human stuntwoman who ended up trapped in the media-obsessed Mojoworld, Spiral was forced to serve the despotic villain Mojo, including extensive surgeries to graft multiple arms onto her body. Mojo trained Spiral as both a warrior and a sorcerer, but as her skills grew, so did her outrage at being forced to serve him. Spiral eventually escaped Mojoworld, ing X-Force at around the same time as Puck.

A skilled sorcerer, Spiral has various mystical abilities including teleportation, energy blasts, and invisibility. She is so skilled at the mystic arts that she was considered as a potential Sorcerer Supreme when Doctor Strange temporarily stepped down.

8 Warlock

New Mutants' Alien Hero Fled the Technarchy

A member of the viral alien species known as the Technarchy, Warlock is considered a mutant of his species because he has no desire to kill his father - a crucial part of the social order of the techno-organic race. Warlock escaped his home planet and ended up on Earth, becoming an iconic member of the New Mutants. While Warlock has a strong friendships with many X-Men, he has a particular bond with Douglas Ramsey's Cypher, and has physically bonded with him on multiple occasions. Warlock's body is made of living technology, allowing him to shapeshift and morph into various tools and devices, including a wearable suit.
