Maria is a major character in the Nibblerflutzer storyline. She is Eric’s cousin, first introduced in the story Villainy Viciousness and Vegetables, in which he accidentally convinces Eric that she is a ghost haunting the building before losing her bracelet and nearly driving him mad.
Maria is a telepath; throughout the stories, her gift comes in handy in protecting her friends and family, and even during the story Shadow’s Survival, killing a Nijax. Her abilities can do multiple things, including illusions, communication, and even the taking of another person’s body briefly (if that person is a Prijax)
Maria is in every Nibblerflutzer story except for the first one (Nibblerflutzer); in fact, she is in more stories than any other character.
