Juda

Juda is a demonic alien and one of the three leaders of the Guar Army alongside his siblings Gina and Mold. He is the main antagonist of the film, Ultraman Story, as well as one of the main villains of the Andros Super Warriors miniseries.

History
Juda was born from a Spacial Distortion. He desired to spread the distortion around the Universe, strengthening himself but threatening the stability of the Universe.

Father of Ultra attempted to fight him, but found that he literally could not fight Juda. However, using training from his father and grandfather, Father of Ultra used his Ultra Horns ability to gather large amounts of energy, making him strong enough to repair the distortions in space and defeat Juda.

However, Juda was revived thousands of years later when the distortion that first created him returned. Upon his return, Juda revived Alien Hipporito to attack earth. While Ultraman Ace fought the alien, Juda went to battle and get his revenge on Father of Ultra Juda triumphed over Father of Ultra and beat him within an inch of his life. Juda's next move was to revive the monster Enmargo to attack Earth.

When Taro went to Earth to stop Juda, Juda summoned the spirits of Alien Baltan, Red King, Gomora, Alien Mefilas, Eleking, and Alien Hipporito and combined them to form the Grand King. Ultraman, Zoffy, Ultraseven, Ultraman Jack and Ultraman Ace all tried to combat the machine monster but proved ineffective against it. However, the five Ultra Brothers merged with Taro, granting him the power to destroy Juda's creation. After Grand King was destroyed by Taro's Cosmos Miracle Beam, Juda then fled to the deepest reaches of space.
