The Nerb Dark Egg Legion was a Dark Egg Legion chapter comprised of Nerbs, a race of Mobians who lived underground in Mobius' original reality. Led by the Foreman Nerb, they overthrew the Nerb King and enslaved the Kraken race to serve as beasts of burden. While most of the species either served willingly or were cowed into subservience, the Legion did face some resistance in the form of the Nerb Freedom Fighters.
