Biography
At age 18, Amanda Krueger decided to become a nun, choosing "Mary Helena" as her name in Christ.

In 1941, her first assignment as a nun was to care for the inmates in Westin Hills hospital, including the infamous tower (where the most insane patients were locked up). Only a few days away from Christmas, Amanda was accidentally locked in the tower when the guards were in a hurry to go home to their families. She was left alone with the inmates for several days, and she was brutally raped and beaten many times during this ordeal. When she was finally found, she was barely alive and pregnant.

Nine months later, Amanda gave birth to Frederick Charles Krueger (aka Freddy Krueger). Shortly after, the infant was given over to the state and adopted by Mr. Underwood, an abusive alcoholic.

Amanda Krueger followed her son's trial after he was arrested for the murders of several neighborhood children. Freddy was released on a technicality and Amanda was distraught, dying by suicide shortly after she heard the news. Amanda's body was never found. The tower, where she hung herself, was sealed and that wing of the hospital closed. A head stone was placed in the Springwood cemetery for "Sister Mary Helena". Amanda Krueger would return twice, in spirit form, to help those that were fighting her son Freddy. Her first appearance was in Dream Warriors. Amanda appeared as an old nun going by her name Sister Mary Helena, trying to help doctor Neil Gordon to save the last Elm Street children. At the end Neil found her grave site and learned Freddy's mother had been helping them.

The second time was in The Dream Child. After his defeat in the The Dream Master, Freddy used Amanda to give birth to him again in the dream world. Upon his return, he remained afraid of his mother's power and tried to keep her sealed away. Alice Johnson, the heroine of the film, needed to find Amanda's resting place so that this power could be used in the fight. She didn't have enough time to search, so she had a friend try and find the body. The body was found and Amanda's spirit was freed just in time to help Alice defeat Freddy. After his defeat, Freddy was left in his infant form, which Amanda then absorbed back into her. Eventually he escaped, continuing his reign of terror in Freddy's Dead.
