Emperor Mateus Palamecia, also known as the Emperor of Palamecia, is the main antagonist of Final Fantasy II. He is the oppressive ruler of the medieval-esque land of Palamecia and the fearsome figurehead of the Palamecian Empire who aims to conquer the world through demonic forces.
Though known simply as the Emperor in Final Fantasy II, he is named Mateus in the game's Japan-exclusive novelization: "Final Fantasy II Nightmare's Labyrinth" by Kenji Terada.
