Lancelot is the son of the Fox Sin Of Greed, Ban and the guardian Elaine, and the prince of the Kingdom of Benwick. He is also a Holy Knight of the Kingdom of Liones, and one of the Four Knights of the Apocalypse. At the age of 10, he went missing with his attendant Jericho, having been kidnapped and taken to the Lady of the Lake's realm, where he successfully fought against and absorbed all the power of the Lake and the Lady herself into his body, essentially becoming her vessel before reappearing three years later into service of Liones. Six years after his disappearance, during the events of Four Knights of the Apocalypse, he appeared as a mysterious talking fox named Sin and accompanied Percival in his journey, and would ultimately return to his human form, aiding Percival as his friend and fellow Knight of Apocalypse. He has magenta red eyes and short blond hair that reached his chin, but later cut it much shorter to look more like a boy's, revealing the scar he got from Tristan in a fight. As a teenager, Lancelot is taller and with more defined musculature. His hairstyle is more pointed, more similar to his father's. He wears a sleeveless white and red shirt with a white hood, red pants, and white shoes. These clothes were made by his uncle, King. He wears white cloth wristbands that hold his arrows and his Fairy Bow on his back. As Sin, he takes the appearance of a small fox with strawberry red fur covering most of his body, except on the underside and the tip of his tail which are white. He wears a collar with a small crystal pendant around his neck and his eyes often appear closed. This shape and his name are in honor of his father. At first glance, Lancelot appears to be cheerful and friendly towards a con artist merchant, appearing naive and innocent, but he later revealed a crueler side, similar to his father, when he sees that the merchant was tricking the fairies with junk to get their treasures. Just like his mother, Lancelot always seems to be a very serious, quiet, stoic and responsible person, however, he also takes a little after his father, such as his sloppy and playful nature. Like his parents, he rarely shows any compassion for his enemy, never hesitating to kill them when necessary. Although he rarely shows it, he cares deeply for those he loves, determined to punish anyone who makes them suffer.
