Biography
Captain Britain was given his powers by a disguised Merlin the Wise, who was subtly directing Braddock's life to make him mentally and physically prepared for a task. Merlin would once resurrect Captain Britain from the dead. (COMIC: A Rag, a Bone, a Hank of Hair...)

After the death of several members of the X-Men, he eventually became one of the founding members of the new team Excalibur. (COMIC: The Sword is Drawn)

He later attended Bonjaxx's birthday party at Maruthea. He wore costumes decorated with a Union Flag design, and another that was a red jumpsuit.

Two different versions of him participated in a fight which was started by a Meep: one fought a cyborg with a chainsaw arm, while another fought John Steed and Emma Peel. (COMIC: Party Animals)

Captain Britain also offered Death's Head and his future self to help fight Hob, but they refused. (COMIC: The Incomplete Death's Head)

Behind the scenes

 * Captain Britain was Marvel UK's flagship character in the late 1970s and early 1980s. His ties to Doctor Who Weekly were written by Alan Moore and drawn by Alan Davis, both DWM alumni; Moore was also friends with Merlin creator Steven Parkhouse. Many years later, Paul Cornell would have Merlin the Wise appear in his Captain Britain and MI:13 run.
 * Captain Britain is seen three times in Party Animals wearing three different costumes. First, he is wearing his original costume from Captain Britain Weekly (1976-77) while standing with Captain UK. Next, he is wearing his new costume from Marvel Superheroes #377 (1981), The Daredevils (1983), Captain Britain (1985-86), etc. while punching the chief of the cannibals. Last, he is seen wearing his costume from Knights of Pendragon (1990-91) while holding John Steed. As three different Doctors were present, this could mean Captain Britain is there three times too.
