Alicia Masters is the step-daughter of the Puppet Master. After her parents died in an accident, Phillip Masters, decided to take her in, especially after exhibiting her gifts as an artist. During the horrific accident that took he parents life, Alicia was also struck with blindness, but amidst it, she still retain her artistic gifts and became quite a sculptress.

Her first encounter with Fantastic Four, came when she aided him against a plan of attack against the team. She had no personal grudge against them, instead acting out of love and obedience for her father. When she comes in contact with the Thing for the first time, and after touching his face, she manages to see into the soul of this person with the monstrous appearance and realizes that he has a deep and caring heart. This encounter would begin the on-again, off-again relationship that would define Ben and Alicia's relationship. At the same time of this encounter she begins to see through her father's true colors. She finally sees Phillip for what he is and helps the Fantastic Four in defeating him.

The encounter with the team would give rise to their long-standing friendship and relationship with Alicia. Alicia becomes an integral character in the Fantastic Four lore because she's one of the main characters of the supporting cast. She becomes godmother to Franklin, and both she and Sue share a very close friendship. She is also considered part of the family, that is the Fantastic Four.

When the Silver Surfer first arrived on Earth as a herald of Galactus, it was Alicia Masters' pleading that first made the Surfer understand the value of life, leading him to betray his master.

During later stories, a romance between Alicia and Human Torch slowly comes to rise after the events of the Secret War, that saw Ben staying in an alien world because he could transform into his human self there. Alicia and Johnny fall in love and eventually get married. But later it's discovered that Johnny had never married Alicia. He'd married a Skrull by the name of Lyja who had used Alicia's form to infiltrate and destroy the Fantastic Four. The real Alicia had been kidnapped by the Skrulls and kept in a safe place so she wouldn't hinder their plan. She was eventually rescued by the team and the Torch and Lyja's marriage went, understandably, through turmoil due to the trickery.

Alicia is a noted and famous Sculptress. She has a special gift of looking into the inner soul of people and creates incredible life-like statues to celebrate them. She is most well known for making sculptures of her close friends, the Fantastic Four.
