Freedom League: Rebirth
SHADOW, or the Secret Hierarchy of Agents for Dominion Over the World, is a villainous organization that became active in the sixties. Since then, it has been lead by a mysterious villain as the Overshadow, an armored man who is as cunning as he is evil. Throughout the 20th Century, the Overshadow and his minions have made hundreds of attempts to conquer Earth, but the Freedom League and other heroic teams have always been able to stop them.
In 1990, the Overshadow fell to his death in a fight with Jack Simmons, the former Patriot and then-director of AEGIS. SHADOW technically have been active since then thanks to the Penumbra (Overshadow’s council of advisers and generals), but they have yet to pose a significant threat to the world since the Overshadow’s death.
