The Age of Apocalypse was a divergent reality that was created when Professor Xavier was killed in the past by his son Legion, resulting in a dark new chain of events that saw Magneto form his own X-Men as Apocalypse rose to power and took over North America as his stronghold for a war against the rest of the world to fulfill his tenet of "survival of the fittest."

While most of the characters that appeared were altered versions of already established heroes and villains in the Marvel Universe, there were a number of new characters introduced who only appeared during the event or managed to find a new life in the mainstream reality after the X-Men were able to reverse the death of Professor Xavier.

10 Abyss

Fabian Nicieza and Andy Kubert's Amazing X-Men followed Quicksilver's squad of X-Men as they helped with a human evacuation away from North America, which brought them into battle with one of Apocalypse's Horseman, Abyss.

While not much was learned about the character from his few appearances in the AoA beyond his ability to transform his body around the void it contained, his 616-reality counterpart Nils Styger later appeared and revealed more about the character's ability and history as one of Nightcrawler's half-demon siblings with a connection to the Darkforce Dimension.

9 Elizabeth Guthrie/Amazon

While Elizabeth "Lizzie" Guthrie technically first appeared as one of Sam Guthrie/Cannonball's young and potentially mutant siblings in the pages of The New Mutants, a new version of the character that hasn't appeared in the mainstream reality appeared in the AoA.

Elizabeth appeared in John Francis Moore and Steve Epting's Factor X as Amazon, one of the members of Apocalypse's Elite Mutant Force. She was a metamorph, which allowed her to increase her size and strength at will, though the mainstream version has yet to display this ability.

8 Vincente

Scott Lobdell and Chris Bachalo's Generation Next followed Colossus and Shadowcat's young team of mutants as they attempted to rescue Illyana Rasputin from one of Apocalypse's slave pens in the power core of Portland.

While most of the young students were reimagined members of Generation X, they were joined by a young mutant named Vincente who was able to transform into other states of matter like poisonous gas or liquid. Vincente would later appear in the 616 reality as one of Emplate's vampiric group of Hellions.

7 Holocaust

Nemesis was the son of Apocalypse and one of his most powerful Horsemen who took the name Holocaust and cruelly ruled over his divided parts of the country, which brought him into conflict with Rogue's squad in Scott Lobdell and Joe Madureira's Astonishing X-Men.

Holocaust was trapped in a bio-containment suit that contained his powerful energies, which he resupplied by absorbing the life-force from other living beings. Holocaust was one of a few characters from the AoA that found themselves exiled in the 616, though his time with the reality-hopping Exiles led to his death.

6 Dark Beast

While Hank McCoy/Beast was one of the founding members of the X-Men and has appeared in the 616 reality since the 60s, an entirely new version of the character known as Dark Beast appeared in the AoA as one of Apocalypse's twisted genetic scientists. Without Xavier's influence, McCoy's scientific curiosities were pushed further by Mister Sinister, turning him into the Dark Beast.

The evil McCoy was able to find his own escape from the AoA reality into the 616 reality, though he arrived twenty years in the past. This led to his continued experimentation and revealed his hand in the creation of the mutant Morlocks who lived in the sewers.

5 Bedlam Brothers

Apocalypse's Elite Mutant Force was comprised of a few different teams of powerful mutant siblings that included the Summers brothers as well as the aforementioned Guthrie siblings, but it also introduced readers to the Bedlam Brothers in Factor X.

Jesse and Terrance Aaronson had similar psionic abilities that allowed them to disrupt both mental and mechanical frequencies. Jesse Aaronson/Bedlam would later appear in the pages of X-Force and join the team, though his brother in the 616 was named Christopher and later appeared as the villainous King Bedlam.

AoA Blink

Clarice Ferguson/Blink first appeared during the "Phalanx Covenant" event that preceded the Age of Apocalypse, though she sacrificed her life for the other young mutants that would form together as Generation X.

However, a new version of Blink that had become a battle-hardened warrior alongside her mentor Sabretooth appeared as one of Magneto's X-Men in the divergent reality before she too escaped the erasure of the reality as one of the dimension-hopping Exiles who were tasked with saving the multiverse.

3 Sugar Man

Sugar Man in Age of Apocalypse

Apocalypse gathered a number of warped mutant geneticists like Sugar Man to his cause with the intention to not only create stronger mutants but to also experiment on and transform captive humans into "useful" tools for mutants like Apocalypse's powerful army of Infinites. Sugar Man was in charge of a number of slave pens that worked to power Apocalypse's new world.

Sugar Man was able to alter his size and increase his mass when needed, which allowed him to escape to the 616 reality. Like Dark Beast, he arrived twenty years in the past and settled on Genosha, where he helped create the mutate enslavement process.

2 Kirika Yashida/X-23

Kirika Yashida/X-23 in Age of Apocalypse

The mainstream 616 reality's X-23 is Laura Kinney, the artificially-created daughter of Logan who went on to become the All-New Wolverine and work alongside a number of X-Men teams as she's matured over the years.

While the AoA didn't initially introduce its own version of the yet-to-be-created X-23, a later storyline that revealed the Age of Apocalypse reality had survived introduced Kirika Yashida/x-23, the daughter of the AoA's Logan/Weapon X and Mariko Yashida who would reappear briefly in the pages of Rick Remender and Mark Brooks' Uncanny X-Force.

1 Nate Grey/X-Man

X-Man introduced readers to Nate Grey, a powerful young mutant who was created by Mister Sinister in the AoA universe after he combined the genetics of Scott Summers and Jean Grey, though he was able to escape and eventually assisted in the final defeat of Apocalypse by entering into a final battle with Holocaust.

During that battle, Nate stabbed Holocaust with a shard of the M'Kraan Crystal, which transported both of them to the 616 reality. Nate Grey began his life as an alternate version of the mutant known as Cable, but he soon found his own path that ultimately led to the misguided creation of his own reality during the Age of X-Man event.
