Unicorn

Unicorns are horse-like creatures with a horn growing from their foreheads.

They once bestowed healing power, but perhaps due to the corruption of the elf hero Oberon Greenhaze and Evernight Forest they became bloodthirsty in Overlord.

In Overlord II the unicorns have apparently recovered from their corruption and have been captured by the Glorious Empire for use in the arena. A few unicorns can also be found in The Last Sanctuary.They also drop Fairy Gems in Overlord II.
