Eel-Man

pages 54-55

Eel-Man is by far the least popular superhero to come from the Silver Age of Comics.  His origin story has an ordinary freshwater eel get bit by a radioactive accountant, and subsequently mutating into Eel-Man.  It lasted for half an issue, as the final 6 pages of the comic were never drawn due to extreme apathy on the part of the inker.  It's just 6 pages of blank boxes and speech bubbles.
