Unicorn

An Unicorn is a race of pony with a horn that allows him or her to produce magic and suspend a object n their by using their horn. There are some unicorns that are ver talented at magic and are seen using it a lot, such as Rarity or Twilight Sparkle, or those unicorns that almost never use their horn. Princess Celestia, Princess Luna, and Princess Cadence all have horns, though they also have wings, making them Alicorns.

Abilities
 Suspending items or other ponies  All unicorns are shown to be able to suspend things in the air with their horns. While they do this, a magical glow surrounds the object he or she is affecting, as in most other spells. If the pony keeps his or her spell going when he or she moves, the object will move along with the unicorn.

 Magical barrier  Some unicorns can create a magical barrier around whatever, whoever, or wherever they want, making it impossible for anything or anyone to enter the area the barrier is surrounding as long as the pony maintains it daily. Only Twilight Sparkle and Shining Armor are ever sown doing this, Twikight using the spell multiple times.

 Teleporting  Some or all informs are able to teleport from one place to another with their magic. While teleporting the unicorn simply needs to perform the spell, and he or she will teleport to the place he or she is thinking of. Twilight Sparkle has used teleportation many times in many episodes, but not as much as she has suspended an object in the air, which obviously she does many times, seeing as she has suspringly better magical abilities than any of the unicorns in Ponyville, or maybe even Equestria.
