The first of its kind, Caïus, is considered amongst its people as a savior and a hero. He is a strong believer in life and will defend it until his very last second of existence. The one regret Caïus has of his life is his transformation. He despises his own reflexion and has been known to shatter it when confronted by a mirror. Even thought his peers view him as King and the leader of the Cyber. Caïus could never take the mantle of ruler of his people as he deems himself unworthy of it.

His transformation left but his brain as the last part of his body that is still human. Standing over 9 feet tall. Caïus has led the Cyber into battle for the last four centuries, always first in line to meet the One head on. As his name suggests, he chose the body of a golden giant, his limbs are holding in with a system of electro-magnets that serve both as a form of locomotion and as weapon.

Caïus was one of the first to suggest mechanization of the body to fight the One and was also the first to back down from the procedure. If he had gone through with the extraction of his humanity, Caïus would have been one of the first Scions. Caïus holds himself responsible for the existence of The Scion and all that they have been doing for the past centuries. As one of the founders of the Cure he will never be able to let go of that guilt.
