Claudio S. Darlton is a minor character in Code Geass. He has curly and brown hair. He's voiced by Sam Riegel in English version.
Claudio is a member of Glaston Knights. He is usually calm and polite to everybody, even to his former enemies. He leads the Glaston Knights whenever their commander is absent.
After arriving with the Glaston knights in Area 11, his team acts as Cornelia's personal guard. Towards the end of Season One, his team helps to fight off the Black Knights and capture a large portion of their members in the Assault on Tokyo Settlement.
In the second season, Claudio and fellow Glaston Knights' members appear while Zero announces his return and declaration of formation of the United States of Japan. During the scheduled execution of the captured members of the Black Knights he fights to stop the prisoners from escaping. He and Edgar then agree to duel Knight of the Round Gino Weinberg, who was testing the security of Area 11's Government Building.
During the Second Assault on Tokyo Settlement, he escapes the F.L.E.I.J.A. that was fired by Suzaku under the influence of Lelouch's Geass. Claudio is the one who orders the retreat, allowing most of the Empire's forces to escape the blast radius. He is later shown registering citizens who escaped the F.L.E.I.J.A. in Ashford Academy and is again seen on Horai Island, asking Villetta about Cornelia's condition. He is later seen aiding Cornelia's attack on Lelouch's forces after his death.
