In the Red Dwarf universe, Superhero Costumes were used for a variety of reasons.
Dave Lister apparently possesed a Spider-man costume for the purpose of making his sex life slightly more exciting. He offered to put it on for Camille while they "recreated" the Human race (RD: Camille).
Mr. Ackerman also owned a Batman costume and used it in his affair with another officer's wife. On one occasion, he didn't allow enough time to change out of the costume, which resulted in his being late for work. Lister suggested that he should play Tarzan next time, as the costume change would be much quicker (RD: Pete I).
Behind the scenesEdit
In commemoration of Red Dwarf's 50th episode, the Radio Times ran an article depicting the main characters as superheroes.
