Izabel

Izabel is a witch villain from Puella Magi Madoka Magica. She's one of the witches who appeared in the tenth episode. Her name appeared in the episode as Isadel, however a card that was released later corrected her name to be Izabel.

Izabel is the artist witch whose nature is vanity. Without a slightest doubt, she believes her existence is blessed. Wanting someone to see her work, she often interfere with human world. However within her barrier only exist works that you have probably seen somewhere before. To defeat this witch, just bring a well-known critic with you.

Plot
Presumably because of suicidal thoughts that she got on her way to school, Homura wanders into the barrier of witch Izabel. She is quickly saved by Puella Magi Madoka and Mami, who destroy Izabel, with Madoka asking her to keep their jobs a secret from schoolmates.

Speculations & Observations

 * She seems to be able to speak, being the only witch who spoke something so far (Except Elly who could speak with Backmasking).
 * There is a possibility that a witch's speaking can be understood only by people who have been targeted by her.
 * Her barrier seems to be art-related. For example, the patterns Homura walks over before being engulfed by her barrier bear a striking resemblance Pablo Picasso's Guernica, and Izabel is killed while bound to a facsimile of the Arc de Triomphe.
 * Her name may have been derived from Princess Izabela Czartoryska, founder of the first Polish museum.
