Gorm:
The main antagonist of the series. Once the chief advisor of the Royal Court of Galidor, he plotted against Sam and Queen Riana by causing a riot on Kek. After his plot was exposed, Queen Riana repelled him and banished him from Galidor. Since then, Gorm has conquered many realms, wiped out some species (like the Amphibibs), shrunk Nepol, burned Jens' body, and made a virus in the Outer Dimension's Maps. As such he is known as the "Conqueror of a Thousand Worlds." He has the ability to glinch, which is amplified by a device on his chest. Among Gorm's other skills are his immense strength, telekinesis, and intellect. Gorm has since sought to take over Galidor and has enlisted many allies to help him in his quest.Played By: Derrick Damon Reeve and Steven P. Park
