Captain UK

Captain UK (alias Linda McQuillan) is a fictional character created by Alan Moore and Alan Davis for Marvel Comics.

Fictional character biography
Linda McQuillan was the hero Captain UK on the alternate Earth designated Earth-238. She fled her home reality to avoid dying during a superhero purge instigated by Mad Jim Jaspers and carried out by the Fury, and took up residence on Earth-616, the mainstream Marvel Earth, abandoning her costumed identity. Learning that this reality's Jaspers was about to repeat the same events in this reality, she contacted her counterpart, Captain Britain, to warn him, and subsequently became his reluctant ally against both Earth-616's Jaspers and the Fury, which had pursued her and Captain Britain to this reality after the destruction of the Earth-238 continuum. Having resumed her Captain UK identity, she was subsequently sent by Roma to Earth-794 to replace the deceased Kaptain Briton and lead a rebellion against Sat-Yr-9, deposing the tyrant and restoring peace. She was later reassigned to Earth-839.

Captain UK is often treated as Number Two to Captain Britain and is a member of the Captain Britain Corps. She is married to Rick; the Earth-238 version of 1950s UK superhero Young Marvelman. Slain by the Fury during the hero purge, he was resurrected by Roma and reunited with her just prior to her Earth-794 assignment.
