The first of the Thirteen Primes of Cybertron. A wise, noble, and righteous Knight of Light. He has a gentle and calm personality, but is more of a cheerful, easygoing man than one might expect. He wields a greatsword called the Star Saber. He has a habit of resting his greatsword over his shoulder during combat or training. He has blue eyes that look half-closed and a face that seems to be smiling. He speaks in a polite but friendly manner (not informal). He is serious while on duty.
