M, and her powers were actually the result of a secret experiment. They believed the experiment to be a failure and had returned her to whence she had been taken, leaving her none the wiser. Later that year, the Japanese plot their attack on Pearl Harbor. Uncle Sam learns of the attack and assembles a group of heroes called the Freedom Fighters (with Hourman, the Invisible Hood, Magno, Neon the Unknown, and the Red Torpedo) to prevent it. The mission is doomed and all but Uncle Sam seemingly perish in the fight. Sam later discovers that three of his allies had survived, Miss America among them. After the mission, she is reclaimed by Project M. When Robotman and the Young All-Stars visit Project M, they discover that Miss America is indeed alive, albeit comatose.

Learning that Hector can only exist for one hour outside the Dream Dimension, Lyta and Hector marry and Lyta joins Hector in the Dream Dimension. Joan and Derek Trevor attend the wedding.
