David T. Darlton (デヴィッド T ダールトン, Devuiddo T Dāruton) was a quick-tempered, dark-skinned and red-haired man. He was the member of the Glaston Knights. He had the highest respect for his adoptive father, Andreas Darlton. He was also the only member who was ever affected by Lelouch's Geass.
David makes his first appearance, along with the other Glaston Knights, after arriving in Area 11. David plays a role in defeating the Black Knights during their attempted rebellion in the season one finale.
David first reappears participating in The Black Knights members' execution, as well as keeping a watch for Zero in the case that he would come to rescue his subordinates. He desires to kill Zero out of revenge for killing his father. However, before the execution, Lelouch tricks him and cast his Geass upon him; he then gives the order to shoot Rolo so that Lelouch can "save" him.
When Black Knights assault the ship that bringing new Viceroy of Area 11, Nunnally vi Britannia, from Britannia to Japan, David, alongside Guilford, was one of the team members sent to retrieve back the ship.
During the second battle of Tokyo, he and the remaining Glaston Knights fight against the Black Knights and manage to hold their ground.
However, he is killed by Chiba with Kallen's assistance and apologizes to his father for letting him down and asks for forgiveness as his Knightmare explodes. Claudio yells David's name as what is left of his Knightmare falls.
- Although he was affected by Geass, it seems that nobody realized it, including himself. This may be why he is not included in the Geass Injured Persons List, created by Kanon Maldini.
- "Show yourself, Zero! My father, Andreas Darlton, shall be avenged!"
- "Father, I let you down. Forgive me!"
