The Forever Knights are a secret British society/paramilitary group first formed during the Middle Ages that are dedicated to collecting and studying alien technology, usually by illegal means. Any aliens they capture along the way are dissected and studied, and any humans caught with them are immediately deemed worthless and disposed of. They also have robotic dragon that protects one of their castles. It is revealed in Ben 10: Ultimate Alien that the reason for their actions is to combat Diagon, an entity from another dimension that nearly conquered the Earth in the Middle Ages were it not for the Forever Knights' immortal Founder George. When George left them, the Forever Knights began to splinter under various self-titled Forever Kings who transformed their knights' duty into a genocidal policy toward anything alien. The Forever Knights also arm themselves with a large variety of medieval weapons enhanced by alien technology, with Lightsaber-like swords, lances, "laser lances", laser guns and electroshock rods being their most common weapons.
