Emperor Xul ズール皇帝

Emperor Xul is the dictator in control of Gishin and many other planets he has conquered. When Takeru was a baby, Xul took him from his biological parents and sent him to Earth, with the mission of destroying the planet when he's older. A cruel ruler, Xulhas enslaved many people and inspired many rebellions. His ultimate wish is to control the entire known universe.

Nobody can confirm if he is even human, because he is never seen without his mask and cloak...
