The core of the Legion was originally made up of soldiers from spec ops divisions who were sent on Utopia with a secret mission. When the planetary disaster broke out, they refused to join the Marauders, instead becoming a truly combat-capable army.
They were tempered in endless battles against the robots of the Dominion, a renegade AI that is trying to destroy the human race. The war for humanity's very survival forced the Legionnaires to forget about pity for its individual members. In order to stand against the enemy, the Legion constantly cultivated its power, stopping at nothing.
Its roster swelled with captive Crimson Marauders who were transformed into obedient, fearless soldiers after a medical procedure. Production continued without end at their bases, and scientific experiments were conducted constantly in their laboratories. Thanks to this, the Black Legion now possesses heavy armored vehicles, helicopters, state-of-the-art weapons, both invisibility and regeneration technologies.
However, the Legionnaires eventually encountered an enemy they couldn't handle. The Legion's headquarters was conquered and its commander General Kurbatov was killed. Colonel Morales, also known as the Gorgon, was supposed to replace him. However, at that moment she was overseeing Captain Blake's transformation at a top secret base. As a result, other commanders appeared in the Legion who refuse to share their authority. Morales and Blake now consider them traitors and renegades. There will be no peace between them.
