Anthony Carter operates primarily under the alias Anthony Rester, serving as second-in-command and operations leader of the Special Provision for Kira (SPK) under Near. To conceal his identity during the Kira investigation, he uses aliases like "Anthony Rester" and "Mr. Richards." Prior to the SPK, he was captain of a special forces squad, bringing tactical expertise and leadership to the organization. Standing 193 cm tall and weighing 84 kg, Rester possesses a muscular build with blond or graying hair and blue or gray eyes. He maintains a professional appearance, typically wearing white dress shirts, black ties, and dark trousers, sometimes equipped with a shoulder holster during field operations. As Near's most trusted field operative and de facto guardian, Rester handles urgent operational tasks, day-to-day logistics, and practical matters unfamiliar to Near, such as booking flights, piloting aircraft, and managing international travel. He also acts as Near's caretaker, providing personal support like purchasing toys. Near exclusively confides strategic plans and thoughts in Rester due to his honesty, reliability, and calm professionalism. Official statistics rate his intelligence at 7/10, creativity at 6/10, activism at 8/10, emotional strength at 7/10, social skills at 7/10, and language skills at 10/10. His skills include advanced lip-reading, surveillance evasion, tactical command, and physical combat. Rester played a critical role in high-stakes operations, notably assisting Stephen Gevanni in swapping the Death Note. He is the only SPK member Near is certain was never seen by Kira, contributing to his survival. While sometimes struggling to comprehend Near's methods, he executes orders diligently. Following Kira's defeat, Rester continues working with Near, Halle Lidner, and Stephen Gevanni, depicted three years later in *Death Note: The A-Kira Story*. In this sequel, he feigns ignorance of Shinigami, adding ambiguity to his awareness of the notebook's supernatural aspects despite prior statements that all SPK members touched it. Trivia notes include his birthday on January 6 (with cited birth years of 1968 or 1971), blood type O, enjoyment of haiku, and a strong dislike for traitors. His age is depicted as 41–42 during the main series, 45 in the initial sequel, and 51 in newer special episodes.
