Composite SupermanAlter Ego: Joseph Meach
First Appearance: World’s Finest Comics #142
Another gem from DC’s Silver Age is the Composite Superman. Originally a janitor at a Metropolis museum, Joseph Meach was belted by mysterious radiation while at work and was randomly transformed into this hybrid of Batman and the Man of Steel.
Gifted with godlike physical abilities, but retaining the mind of a lowly janitor, the Composite Superman was easily defeated by the Caped Crusader in their first encounter. Lesson learned: Don’t infringe on the Dark Knight’s trademark tights.
