// Archive commentary
Action Comics #340 (DC Comics, August 1966) leads with "Power of the Parasite!", a 14-page story written by Jim Shooter and drawn by Al Plastino that introduces the Parasite, Maxwell Jensen, a villain who drains the energy and powers of anyone he touches. He went on to become one of Superman's recurring foes.
The backup is "The Supergirl Identity Hunt!", a 10-page Supergirl story drawn by Jim Mooney, and the issue carries a double-page pin-up of Superman, which is missing from many used copies. The cover is by Curt Swan and George Klein.
It is collected as the Parasite's debut, a Silver Age Superman key, and copies with the pin-up still in place are the ones buyers look for.
