Hyathis is an extra-terrestrial conqueror and enemy to the Justice League. Her home planet Alstair is constantly at war with Dhor, Llarr and Mosteel; this puts her against their dictators Kanjar Ro, Kromm and Sayyar. The Alstairans are biologically human/plant hybrids; she is an elemental with telepathy and empathetic control over plant life. Hyathis was created by Gardner Fox and Mike Sekowsky, first appearing in Justice League of America #3. (1961)
