Olivia (Sabina Odone) is the main rival and antagonist in the 2005-2006 Chilean fantasy TV series "Magi-K". Magi-K was the Chilean answer to Harry Potter.
Olivia is a high school age girl, and the main rivalry with the main character Isidora (Catalina Palicios). Olivia is envious of Isi because of her sorceress power, and since she attends the same school, she has been asked to follow Isi around and report back to her mother, Venus (Monica Aguirre). Venus is an evil and ambitious witch, whose objective is to get a hold of the Book of Power. With the book, Venus will be able to link the world of magic with that of the present. The Book of Power is owned by Isi. If Olivia ever finds a chance to snatch the book herself, she is to attenpt it.
Olivia possesses supernatural powers herself, but she is not as powerful as her mother. In one episode, Olivia turns one of the boys into a warewolf. In several others, she fires lightning bolts at Isidora. In each of those instances, Isi is able to deflect the power back at her and defeat Olivia.
Isi's best friend is Matide Farias (Maria Luiisa Mayol), and she is constantly being targeted by Venus and Olivia.
In one episode, Isi and Matilde encounter Venus in the park. Venus turns Matilde into a cat, much to the fear of Isi. Isi takes Matilde the cat home to try to use the Book of Power to change her back. However, the cat runs out the door and to the park. She is chased by three big dogs, who chase her up a tree. Isi is able to get her back home. The next morning, Isi takes the cat to school, where the teachers are less than pleased. When the teacher tries to take the cat, it runs away, and is found by Olivia. After getting her back, she takes Matilde to an abandoned warehouse. All of the sudden, Venus appears and offers to transform Matilde back into her human form, if Isi will just give her the Book of Power. Isi returned with a backpack with the book inside it, and Olivia showed up to check the contents. However, Isi had tricked then and placed a worthless pad of paper in it. Before Venus and Olivia figured it out, Isi took back the cat and ran. Venus attempted to shoot a ball of fire at her, but Isi deflected it and then disappeared with a spell. Back at home, Isi began to cry because she couldn't figure out how to change Matilde back into herself. However, one of her tears dripped from her face and that changed her back.
In another episode, Matilde is captured by Venus and tied up in her house. Venus turns Matilde into a turtle, and waits for her to return to Isidora. However, Isi's little sister Selena (Catalina Aguayo) finds Matilde the turtle and thinks she will get in trouble having a pet turtle. She attempts to hide her, and when she takes the turtle to the room they hold the Book of Power in, Olivia is able to steal the book. This theft is only temporary, and Selena, who is a sorceress herself, is able to transform Matilde back into herself.
Still in another episode, Venus turns her daughter Olivia into a fly, so that she can fly to Isidora's home and get information for her. Olivia successfulyy makes the journey and back and is returned to her form by Venus.
