Minister Zuril is a scientist in the Vegan Empire, of equal power to General Gandal.
He's a light-green skinned man with pointed ears. His helmet is decorated with red wings and wears an eyepatch over his left eye which is actually a wearable computer.
He's cunning and ruthless, especially in strategy. He has an intense rivalry with Gandal, often arguing with him over a better plan of attack. They can work together though, shown when tracking down a rogue scientist planning to destroy Grendizer with his own creations.
He has a son that appeared in the 69th episode.
