Abyss

Abyss is the name of two characters appearing in American comic books published by Marvel Comics.

Nils Styger

Abyss is a mutant and the half-brother of Nightcrawler. He was created by Scott Lobdell, Mark Waid, Roger Cruz, and Steve Epting, and he first appeared in Age of Apocalypse: Alpha, which takes place in an alternate reality.
The Age of Apocalypse version of the character is a Horseman of Apocalypse and a living portal who can send others to another dimension.
Years after the Age of Apocalypse event ended, the character was introduced in the main Marvel Universe. This version is Nils Styger, a native of Genosha who possesses the additional ability to transform parts of his body into elastic tendrils.
Abyss first appeared as a protector for Genoshan researcher Renee Majcomb whom he had been assisting with research into the Legacy Virus from which Abyss suffered. However, he did not die due to the actions of Colossus, who sacrificed himself to release an airborne cure to the virus which had taken his little sister Magik's life several years prior.
Abyss was later seen in Berlin, Germany battling the former Gene Nation member known as Fever Pitch. Both mutants were captured by Banshee's X-Corps. While being held by the X-Corps, Abyss witnessed Sunpyre's murder by Mystique. When Mystique revealed herself to X-Corps, the wounded Banshee freed Abyss from his confinement, allowing him to suck Mystique through his interdimensional void, and, unable to shut off his power, almost swallowed Banshee also. The timely arrival of some other members of X-Corps stopped that however. Abyss admitted that he had no idea where Mystique was transported to or if she would ever return.
Abyss later resurfaced when his father Azazel psychically summoned his many children to attempt to release his army from the Brimstone Dimension that he had been banished to hundreds of years before. In an attempt to free himself and his comrades, Azazel had traversed the dimension barrier many times and sired children in the hopes that one of them would be able to breach the dimensional barrier. Abyss joined forces with the X-Men to avert Azazel's attempt to bring his army into Earth's dimension and succeeded in foiling his father's efforts. He was subsequently revealed to be Nightcrawler's half-brother, as both were sons of Azazel.
Abyss is one of scores of mutants who lost their powers after the events of the House of M as he was shown to be among a list of other mutants who lost their powers in New Avengers.
Abyss later joins X-Cell. He was repowered by Quicksilver. When the side effects of the Terrigen Mist began to take effect, he flung Fatale and Reaper into the Brimstone Dimension and followed them.
It was later discovered that the three of them were frozen within the Brimstone Dimension. A.I.M. scientist Dr. Terrence Hoffman later used a machine to extract Abyss, Fatale, and Reaper from the Brimstone Dimension and drained them of their Terrigen energies. After the three ex-mutants were rescued and Hoffman was defeated, Abyss remained silent as Fatale and Reaper vowed to make Quicksilver pay for their near death through the Terrigen Crystals.

Abyss (sorcerer)

The second Abyss is a sorcerer who is the archenemy of the Luminals of Xarth Three and first appeared in Nova #8 and was created by Dan Abnett, Andy Lanning and Wellinton Alves. The Luminals have thwarted Abyss's plans many times and he always returned. In a last ditch effort to rid themselves of Abyss, the Luminals used a spell that cast Abyss to the ends of the universe. Abyss ended up sealed away in Knowhere, a small city contained below the severed head of a dead Celestial. When Abyss was threatening to break out, he managed to make a crack in his prison where his magic started to turn its inhabitants into zombies that obey his every command. A high-grade telepathic dog named Cosmo who serves as the chief of security on Knowhere ordered any survivors to get into the dimension envelope on his tab. Cosmo managed to seek out Nova and tell him of Knowhere's plight.
Cosmo tells Nova all about Abyss and what he can do. While evading Abyss' zombies, Nova and Cosmo head towards Knowhere where they find Abyss' prison slowly breaking down. While Cosmo projects a psychic barrier to block off the incoming zombies, Nova dealt with Abyss. Nova used the Transmode Virus in his possession to interface with Abyss' prison which repaired it and sealing Abyss away once again. Once Abyss was sealed away, the zombies disintegrated and life on Knowhere returns to normal.
