Considering unicorns originally were thought of to be rinos that only had 1 horn. Unlike real rinos that have a big one on the nose and a small one on the forehead. I would have to pick unicorn because a rinos are huge and intimidating.
參考: Modern culture now depicts unicorns as half horse for some reason.
if the undead is not that kind of rotted bodies and dumb enough to attack without a second thought (and mayb somehow handsome or beautiful), i would take undead.
Unicorns. A calvary, an air force, and an artillery unit all rolled into one.
They're an artillery unit because they have rainbow laser blasts that emanate from their horn.
