The Gargoyle is an enemy from Final Fantasy III. It can be found on the World Map near Doga's Manor, including while in an airship. At the time they can be fought, they are of no threat to the party, and one use of Tornado from a Geomancer will most likely kill them.
Gargoyles were initially ordinary stone statues built on rooftops to let rainwater above flow down to the ground through certain paths. The statues were usually carved as monsters and strange creatures, which later spawned the belief that gargoyles are the guardians of the buildings they live in.
