The Captain Britain Corps is a fictional league of super-heroes appearing in American comic books published by Marvel Comics. The characters are all known as, or appear as an alternative version of, Captain Britain, each coming from an alternative reality. Created by writer Alan Moore and artist Alan Davis, the corps first appeared in The Daredevils #6 (June 1983). Founded by Merlyn, his daughter Roma and Sir James Braddock, the organization is tasked with defending the multiverse. The power wielded by members of the corps is derived from absorbing and metabolizing energy generated by the matrix of "exotic particles" naturally occurring at weak points between dimensions, which are present at each dimension's equivalent of the British Isles in unusual quantity and proximity; members are tasked with safeguarding the gateways between dimensions and being the highest champion of each earth's respective morality codes. In addition to the Captains themselves, the organization has included administrators such as Merlyn, Roma, and Saturnyne.
