Rapid Unicorns are villains in the Overlord game series. They were once blessed with healing powers but when the forest of Evernight was corrupted by Oberon, they become blood-thirsty and vicious. They first appear when the Overlord enters Evernight, and the ghost-elves asks him to slay them to end their misery. They helped Oberon fight the Overlord. But their fates remain unknown, after Oberon's defeat.
- Their true corruptor is much worse than Oberon.
- Once they're killed, their horns can be used as weapons by the Overlord's minions.
- Since they also attack the Overlord and prey upon king Goldo's soldiers, it can be considered an Evil Vs Evil-scenario.
