Wonder Man / Wonder Woman - Power man / Power Girl

In October of 1964 Stan Lee introduced the new character to the Avengers; Wonder Man!

In the story he was created by the Masters of Evil to destroy the Avengers. The Avengers took him in as a full member but at the end of the issue, rather than betray the Avengers trust in him, he decided to sacrifice his own life to save them.
 Well it seems that DC didn't like the name of Wonder Man. It was too close to their own very popular Wonder Woman so DC threatened a law suit against Marvel.

The Avengers nemisis - The masters of Evil!

I have been an Avengers fan for as long as I have been a comic fan. One of my very first comics was an Avengers and it still remains a favorite even today. And of the all of the Avengers killer foes, the one that has been the most challenging, the most diabolical, the most deliciously menacing to me has been The Masters Of Evil! They keep popping up giving the Avengers a run for their money!
