E-Man was created by writer Nicola Cuti and artist Joe Staton for Charlton Comics E-Man #1 in October 1973. The original series only lasted for ten issues, but the character has become a cult classic due to it's light-hearted humor, which is similar in style to the golden age Plastic Man.
E-Man is a sentient energy blob which was thrown off by a nova. Traveling throughout the galaxy "E-Man" learned how to duplicate the appearance of life, and about the concept of good and evil. Upon reaching Earth, he met exotic dancer/grad student Katrinka Colchnzski, who also billed herself as Nova Kane, and he physically transformed himself into a superhero called E-Man, with a requisite civilian identity that he dubbed "Alec Tronn". For an emblem he chose the famous mass-energy equivalence formula "E=mc2". His powers include firing energy blasts from his hands, changing his appearance, and transforming all or part of his body into anything he can envision; such as turning his feet into jet engines in order to fly.
Nova was eventually caught in a nuclear explosion and gained similar powers as E-Man to become his partner; although she would later lose her powers and return to being a normal human again. During their earliest adventures they adopted a pet koala named Teddy Q, whose intelligence grew to the point where he held a job waiting tables in a cafe.
