Beatress is a student in the school for the blind. She appeared in "The Third Eye". She was really upset when her boyfriend broke up with her. She goes to The Seers' temple everynight to be alone, however she was put on restriction when caught by a teacher for sneaking out of school at night. One day, in The Seers' temple, she found a medallion that contained a member of the cult while the other twelve are sealed in the temple. She performed a spell that allow the spirit of the cult to possess her body and a third eye to grow on her forehead.
She started to take revenge on the people that caused her suffering. A janitor in her school saw a projection her third eye made of her boyfriend getting blasted down the stairs. Later, it turns out that projected the future when Beatress' boyfriend got blasted down the stairs by her. Martin, Diana and Marvin used the U-Watch to see that Beatress is behind it. Marvin found the room Beatress performed the spell. They saw a projection of a statue falling on Beatress' teacher. They ran out and Marvin saved her. She told them about Beatress and pointed them to The Seers' temple.
They meet Beatress there, she escaped down a gate in the ground. Martin, Diana and Marvin managed to find her. But Beatress took their ability to see. Marvin managed to snatch her medallion, but got possesed by the spirit and got the third eye. He realised the other members of The Seers only to be snatched away by them as they all want his body.
Since the medallion serves as their guide, Martin, with the help of Diana and Beatress captured Marvin in the U-Net and let the medallion rise into the sky with the spirits. The medallion was destroyed along with the spirits of The Seers. She later sniffs out Marvin wearing Dangeroo colone.
