Captain Britain

Captain Britain was an individual who 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 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.
