The Neo were a fictional race of superhuman appearing in American comic book published by Marvel Comics. They are depicted in the Marvel Universe and were created by Chris Claremont. Before facing global extinction, the Neo were another of Earth's races, apparently a very ancient one that preferred to live in seclusion. They appear to be a subspecies of mutants, but much more powerful. This is seen in the way they call mutants "spikes," as if they didn't even register on Neo's power scales.

The existence of the Neo was kept hidden for millennia as they had chosen a solitary life in their own community. They prospered until the day the High Evolutionary activated his machines (from an orbital space station) that switched off all mutant genes. Worldwide, all mutants lost their powers and became baseline humans. The Neo suffered many casualties. Among the dead was the daughter of Domina and Hunter, the leaders of one of Neo's warclans. They swear revenge on whoever is responsible.

The Neo engaged in fighting the X-Men, who had no intention of letting them destroy the world. It was the Neo who sabotaged the High Evolutionary's space station, destroyed 17 of Mister Sinister's bases, and hunted down the mutants hidden by Charles Xavier in NYC. They are all top-notch fighters and can withstand significant punishment before going down. They are also quite technologically advanced.

The Neo themselves had split up into several different factions or tribes. Apart from the Warclan, the different X-Men teams also fought other groups of Neo called "The Shockwave Riders", who have psionic powers and ride anti-grav skimmers, "The Lost Souls", who psychically trap souls near death and cause them to despair forever, "The Goth", a trio of super-powered individuals who acted as a shadowy underground slave trade organization under the lead of a man that called himself "The Goth". They used their own group of inter-dimensional slavers known as the "Crimson Pirates". The Neo groups persisted as legends among mutants even in Cable's time, where it's said even Apocalypse respected them, a testament to their power.
