Egg Fu is a fictional character appearing in DC Comics publications and related media, commonly as an adversary of the superhero Wonder Woman. Most frequently represented as an enormous sentient egg (and often, inexplicably, of Chinese descent), he was created by Robert Kanigher and Ross Andru in 1965's Wonder Woman (volume 1) #157. Over the years, multiple versions of the character have appeared with varying backstories and alternative names (including Egg Fu the Fifth, Chang Tzu, and Dr. Yes) to battle not only Wonder Woman, but also the Metal Men, Checkmate and Harley Quinn.
