The Magic Mirror is a minor character and an object and the former teller of the Evil Queen.
In Snow White and the Seven Dwarfs, every day the Evil Queen asks the spirit inside it whom the prettyest person in her kingdom is. For years it said that she is the fairest. But eventually, it said that her stepdaughter Snow White is now the fairest of all. Out of jealousy, the queen orders a huntsman to kill her and bring back her heart in a box she gave him. Then the mirror ratted him out for bringing bake a pig's heart instead.
In this film, the magic mirror has been reduced to a simple hand mirror. It was Evie - the daughter of the Evil Queen - as a tool to obtain Fairy Godmother's wand. Like most previous versions, it can answer and question, but this time by showing the answer on the glass. And it must be asked a question in rhyme. It will only for the Evil Queen or Evie. Some questions posed it are "Where does Fairy Godmother's wand stand?" and "Who is the biggest jerk in the land?"
The hand mirror that contains a shard of the Magic Mirror starts the short animated episodes off when Evie asks it to show her the future. To see "what happens when" their "stories unfold".
Evie doesn't use the mirror or it's magic like she did in the film, both she and Mal are trying to be good by not using the mirror or Mal's Spell Book. But Evie did talk to it in Voodoo? You Do, after looking at herself in larger a mirror in a shop on the Isle of the Lost. She wanted to make sure that both the mirror and the reflection it gives of her know that she stills loves them: and so the mirror itself wouldn't get jealous. However Evie does use it's magic in Mal-lone, as she asked it to show her where Zevon is.
In the book, there is a magic mirror standing in a room at the forbidden fortress on Doom Island, however: it is unlikely this is the magic mirror, since that mirror is broken and this one is whole. Also, it would be unlikely for the Evil Queen to have the magic mirror on Doom Island since she lived in Charmington. And the Evil Queen is last seen with it there and dies shortly after.
C. J. Hook tries to use it to locate something. She ended up learning that it only works for Evie and her mother.
- In Fairest of All: A Tale of the Wicked Queen, it's revealed that he was Evil Queen's father before he dies and when he was still alive,he was a mirror maker.
- There is a second object from Snow White and the Seven Dwarfs. The box the queen wanted to put Snow White's heart in appears in Descendants as a purse of Evie's.
