Lancelot is a Knight of the Round Table who originates from the earlier series Entaku no Kishi Monogatari: Moero Arthur and appears as a guest character in the sequel Moero Arthur: Hakuba no Ōji. He is introduced in the final episodes of the sequel, where he joins Arthur and Tristram to help bring the story to its conclusion. In the original series, Lancelot is depicted as a close friend and trusted battle companion of Arthur, and this bond carries over into his guest appearance. His background as a knight of the highest skill is implied by his reputation, and he fights alongside Arthur against the forces of the North King Ziking. His motivations are rooted in loyalty to Arthur and the ideal of a just kingdom. While his personality is not explored in depth during the sequel, he is portrayed as a capable and dependable warrior. His notable abilities include expert swordsmanship and knightly combat. Lancelot does not undergo any personal development within Hakuba no Ōji itself, as his role is limited to aiding Arthur in the climax.
