Royd Lloyd is a Quincy and a member of the Vandenreich's Stern Ritter with the designation "Y." He is the identical twin brother of Loyd Lloyd.

From birth, Royd and his older brother, Loyd, where indistinguishable from one another, even to the medical staff that delivered them and their own parents. By the age of 5, the brothers realized the reason behind them being perfectly identical, was that they had both unconsciously begun to imitate the other before being born. When they were 12 years old, they found that they could not only imitate one another, but other people as well. Though neither could copy someone else's appearance, Royd could replicate the person's memories and personality.
