―Wand-powering unicorn (speaking Italian)[src]

The wand-powering unicorn is a miniature unicorn that is used to power up Star Butterfly's wand by running on a treadmill while sustained by a charger.


First unicorn

When healthy, this unicorn has a white coat, starry pink mane and tail, green horn, and a heart on its chest. The head is similar to Pony Head's. When tired, it becomes thin and ragged, its coat is mostly grey, its mane, tail, and horn darken, and the mane and tail go limp, while the heart on its chest looks broken.

In "Storm the Castle", the unicorn is killed when Star casts the Whispering Spell to destroy the wand. Its ghost is last seen leaving the wand and whispering in Star's ear before disappearing.

Second unicorn

At the end of "Storm the Castle," the first wand-powering unicorn is replaced by a second unicorn as part of fulfilling its "responsibility." This unicorn is more mature-looking and has a gray coat, a greenish-gray mane whch it pulls back into a ponytail, a dark blue shirt, yellow and black bands around its hooves, and a detachable horn. This unicorn is also notable in that it speaks fluent Italian.

In "My New Wand!", when Glossaryck looks inside the wand's face plate, the unicorn appears to be in a demented state, and has developed fangs and green eyes.

In "Toffee", this unicorn dies when Star casts the Whispering Spell again to destroy the wand crystal in Ludo's hand.

Third unicorn

Near the end of "Toffee", Star used the last remaining piece of magic in the universe that has not been corrupted by Toffee to give birth to a third wand-powering unicorn. Much younger than the previous two unicorn, this unicorn has a white coat, a dark blue mane, a yellow horn, and a gold butterfly-shaped mark on its haunches.
