Spoiler warning: This article contains information on a Cheat Unit. Please use discretion when viewing this page.

The Learicorn is a strong Cheat Unit in Age of Empires III. It is seen as what appears to be a man in a tuxedo riding a unicorn. The unit attacks enemies by hitting them with what appears to be a crowbar. This unit is hidden in the basic tutorial. A player can view the Learicorn in the tutorial by first building a Dock, construct a Caravel and then transport a land unit to the north-eastern side of the map to make contact with it. A player can also click "Resign" in the Menu options and will be able to view it. It is hostile and extremely strong, and will kill any unit in one hit.
