Brief History

Psycho-Woman was the daughter of the Psycho-Man: a supervillain who specialized in emotion control devices. Unlike her father, who used fear, hate, and doubt as his weapons, Psycho-Woman employed the negative emotions of envy, disgust and indifference.  
  
She attempted to get her revenge on the Fantastic Four for what they did to her father by impregnating a young woman named Amy Brys with Johnny Storm's baby. Hiding inside Johnny's body at microscopic size, Psycho-Woman nearly defeated all three of Johnny's teammates when they shrunk down and entered Johnny's body to confront her. She was eventually defeated when the Invisible Woman's children brought her out from under Psycho-Woman's influence. Psycho-Woman was then apparently incinerated when Johnny Storm flamed-on after his teammates evacuated his body.

Afterward, Amy seemingly decided to go back in time before she was pregnant rather than have Johnny’s baby. But it was not known where in time Amy ultimately elected to go, so it was possible that she changed her mind and the child of Johnny Storm and Amy Brys may have been born at some point in time.
