The New Mutants were teenaged students of Professor Charles Xavier's School for Gifted Youngsters and wore matching uniforms, much like the original X-Men, who had since grown into adulthood. These students, however, rather resembled the "all-new, all-different X-Men" of their era in terms of ethnic diversity.

The original team consisted of:

·         Cannonball (Samuel Guthrie), a mild-mannered 16-year-old Kentuckian and eventual co-leader, who became nigh-invulnerable when he's blastin'.

·         Karma (Xi'an Coy Manh), a 19-year-old Vietnamese girl and the team's original leader, who could mentally possess other people's bodies.

·         Mirage (Danielle Moonstar, originally codenamed Psyche), a Cheyenne and eventual co-leader after Karma's "death," who could create visual empathic three-dimensional illusions.

·         Sunspot (Roberto da Costa), a 14-year-old Brazilian who gained superhuman strength fueled by sunlight and could store solar energy in his body to use his super strength during the night.

·         Wolfsbane (Rahne Sinclair), a 13-year-old religious Scot who could transform into a wolf-like creature.

Claremont gave the series a darker tone, which was heightened with the arrival of artist Bill Sienkiewicz. Sienkiewicz's avant garde art style and painted covers broke though the conventional comic book boundaries of the day and helped The New Mutants stand out on the shelf.

In addition to very serious depictions of teenage angst and growing pains, the series featured themes of mysticism. The stories also relied on wilder, more far-fetched premises than were typical of X-Men at the time, shaping into more of a science fiction and fantasy series than the superhero coming-of-age comic it had been touted as in its early days. Locales included demonic dimensions, alternate futures, and an ancient Roman civilization hidden within the Amazon rainforest. The New Mutants also encountered a secret society called the Hellfire Club, and began a rivalry with their young apprentices, the Hellions.

After the apparent death of Karma, Cannonball and Dani Moonstar act as co-leaders. New recruits included:

·         Cypher (Douglas Ramsey), an otherwise ordinary young man who could learn to read or speak any language rapidly, whether it was human, alien, or machine, making him an unmatched computer expert.

·         Magik (Illyana Rasputin), sister of the Russian X-Man Colossus and long-time resident of the X-Mansion, an accomplished mystic who could open "teleportation discs" allowing travel to Limbo and from there, any point on Earth.

·         Magma (Amara Juliana Olivians Aquilla), a fiercely tempered native of a secret Roman society in the Amazon who can control lava.

·         Warlock, an extraterrestrial of the techno-organic race known as the Technarchy.
