Multiple Man is a fictional superhero appearing in comic books published by Marvel Comics. His real name is Jamie Madrox, and he has the unique ability to create duplicates of himself, known as "dupes." Each duplicate can act independently, allowing him to accomplish multiple tasks simultaneously. First introduced in Giant-Size Fantastic Four #4 in 1975, Multiple Man is often associated with the X-Men universe. He has been a member of various superhero teams, including X-Factor. His powers also allow him to absorb the memories and experiences of his duplicates when they merge back, making him a complex character with a rich backstory.
