X-Men 2099 was a comic book series published by Marvel Comics from 1993 to 1996 that chronicled the adventures of an X-Men team in the year 2099. It extends the Marvel 2099 imprint, which features other future versions of popular Marvel characters, such as Spider-Man 2099 and Hulk 2099. The series was written by John Francis Moore and largely pencilled by Ron Lim.
The series began in October 1993 and lasted 35 issues along with two specials. It spawned a line of action figures, mostly featuring the more popular characters in the book. In issue #20, the title received a minor makeover, officially joining the 2099 imprint and changing its name to X-Men 2099 A.D., the "A.D." standing for "After Doom". At the series' end, it was folded into 2099: World of Tomorrow, though members of the team were rarely seen after that point.
The first issue featured a blue foil cover on cardstock and the double-sized 25th issue's cover was extra-glossy with foil letters, metallic silver ink, and embossed characters on a heavier wraparound cover.
The team featured an ever-changing line-up, but the mainstays included:
- Desert Ghost (Xi'an Chi Xan) – Founder. His right hand was green and covered in scales, and endowed with the ability to break down the molecular structures of substances, thus destroying them; his left hand appeared to be solid gold and had the ability to repair molecular structures, although his use of this power was taxing. He also had the power to generate a protective cocoon, while regenerating and healing. Xi'an was formerly a member of the Lawless gang, who later defected to the Theatre of Pain.
- Skullfire (Timothy "Fitz" Fitzgerald) – Leader. Initial electrical energy absorption and redirection later developed into absorption and redirection of any energy source; ambient, magical, or otherwise.
- Bloodhawk (Lemuel Krug) – Able to assume a superhuman form at will that included tough, scale-like red skin, sharp talons, and leathery wings. Never a permanent member of the team, but came and went when needed.
- Meanstreak (Henri Huang) – Superspeed and a heightened metabolism to prevent his speed from adversely affecting his body. Former Alchemax researcher and star scientist.
- Metalhead (Edward van Beethoven-Osako) – His skin could take on the properties of any metal he came into tactile contact with. Body warped and lost ability to return to human skin due to a mutation caused by the touch of Freakshow member Contagion.
- Cerebra (Shakti Haddad) – Able to psionically "read" and manipulate the nervous systems of others, allowing her to sense the unique bio-signatures of other mutants and control or disable the brain functions of living beings. She could use her power to trigger the latent powers of other mutants.
- Krystalin (Ruth Kirsten Porter-Ogada) – Pulls minerals out of the air and condenses them into hard crystalline shapes of any design she could imagine.
- Junkpile – Techno-organic metabolism increases his strength and durability and allows him to telekinetically draw metallic objects to himself and use them to rebuild his body or add to his physical mass making him unusually resistant to harm. Former member of the Lawless gang. Betrayed team in the second issue, but was later appointed to the new S.H.I.E.L.D. by President Doom.
- La Lunatica – Psychic vampire that fed on dark emotions. Feeding increased her strength and resistance to harm. Chalk white skin and hair as well as red eyes. Initially an instrument of the Theatre of Pain, but after her release fell in love with Skullfire and reformed to become a member of the X-Men.
- Serpentina (Kimberly Kristine Potters) – Negation field renders her bones, tissue, and muscles pliant so that she can stretch them to extended lengths. Killed during first story arc (issue #3). Body was reanimated later in series as a barely conscious zombie (issue #26).

- Master Zhao and the Chosen (One-Eyed Jack, Psycho-K, Wingspan, Frostbite, and Monster) – Zhao was the last leader of the last true succession of X-Men.

The other members are Meanstreak (now a young girl), Krystalin, Junkpile (now a self-replicating Stark android), and Bloodhawk (now female, and with a touch that "can give life, or take it", similar to Xi'an).
