Emperor Daidas

Daidas the Emperor (帝王ダイダス): An giant extraterrestrial being that plots to conquer the Earth by defeating the five Sentai teams (Fiveman, Jetman, Zyuranger, Dairanger and Kakuranger). He is powerful enough to fight against five giant robots (Five Robo, Jet Icarus, Daizyujin, Dairen'oh and Muteki Shogun) at the same time. His only weak point is his third eye.
