Origin
Brian Braddock and his twin sister Betsy (Psylocke) were born of Elizabeth and Dr. James Braddock, an alien from an extra-dimensional realm called Otherworld ruled by and entity known as Merlin.  Unknown to Braddock he possessed latent genetic traits which would manifest as superhuman abilities.

While a student assistant at the Darkmoor Research Centre, the criminal Reaver attacked the facility to steal its secrets.  Attempting to escape, Braddock's motorcycle ran off a cliff and he lay near death.  In a vision, Merlyn of Otherworld and his daughter Roma, Goddess of the Northern Skies appeared to Braddock and bade him choose one of the mystic objects before him: the Amulet of Right or the Sword of Might.  Choosing the amulet he was bombarded with a mystical energy, activating his latent superhuman abilities.  The patron spirits gifted him with a mystic star-scepter to enhance his fighting skills as the champion, Captain Britain.
