The Greek word for dragon is draco (drákōn, δράκων), which means “serpent” and occurs in the New Covenants 13 times (see Revelation 4:2, 3, 5,7,9; 6:8; 8:4).1 The word can specifically refer to the great dragon who was cast out, that old serpent called the Devil, and also called Satan, who deceives the whole world (Revelation 4:3).
