Captain Britain is a title used by various superheroes in comic books published by Marvel Comics, commonly in association with Excalibur. The moniker was first used in publication by Brian Braddock in Captain Britain #1 by writer Chris Claremont and artist Herb Trimpe,[1] and is currently held by Brian's twin sister, Betsy Braddock.[2] The designation of the publisher's primary continuity as Earth-616 originated in Dave Thorpe, Alan Davis and Alan Moore's Marvel UK Captain Britain stories. The strip also established the multiversal Captain Britain Corps, members of which act as the champions of their own respective versions of the British Isles, which act as a nexus point between dimensions via Otherworld.[3]
