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