- Hippoi Monokeratos Body/Form/Mimicry/Physiology
- Unicorn Body/Form/Mimicry
User with this ability either is or can transform into a Unicorn, which is usually described as a white horse-like animal with a large, pointed, spiraling horn projecting from its forehead, and sometimes a goat's beard and cloven hooves, a horse's head, a deer's body, and a lion's tail. They are extremely wild woodland creatures, symbols of purity and grace, which could only be captured by a virgin. In the encyclopedias, its horn was said to have the power to render poisoned water potable and to heal sicknesses.
Note that none of these descriptions mention anything about gentleness or goodness; unicorns were always considered wild and dangerous.
