Crystal Mirror



"Using this magical thing called the 'Crystal Mirror,' you can travel back and forth between Equestria and the human world by going there. No matter what you might wanna use, the Crystal Mirror is here for you to send between these two species-dominant dimensions, one for the ponies... and one for... ya know, ponyoids (or multicolored humans). What if I were a pony if I travel there?"

--Su Ji-Hoon, Ponidox

The Crystal Mirror is a magical mirror featured in the first two Equestria Girls films, IDW comics, software, and adaptations of the films and animated shorts. Twilight Sparkle, Sunset Shimmer, and Spike use the mirror to travel back and forth between Equestria and the human world.

In When the Cold Breeze Blows Away, it would be located in Equestria that it can made the Mane Six trying to travel to between Equestria and the human world.

Also, there's a new version of the Crystal Mirror that allows the Mane Six and the Equestria Girls to travel between Equestria and the human world without having their forms transformed into world-native species (either ponies in Equestria or humans in that other woirld). It's called the Crystal Mirror Mk. II.
