[ Lancelot ]

As a teenager, Lancelot is shown to be taller and more muscular. His hairstyle is spicier, more like his father's. He wears a sleeveless white and magenta suit that was made by his uncle, King.

As a Fairy, he is short and chubby, with wings and turquoise and yellow hair. He wears a red and white jacket, a black glove on his right hand and a gauntlet on his left wrist, brown pants, and black shoes. fox form(Without) As Sin, she looks like a normal fox with pink fur covering most of her skin except for the underside and tip of her tail. She wears a necklace with a small crystal pendant around her neck, in this form her eyes often appear closed.

At first glance, when Lancelot was a child, he appeared to be cheerful, friendly, and naive towards a swindling merchant, but later revealed a more ruthless side after seeing that the merchant was tricking the fairies with trash in order to obtain their treasures.

Lancelot always appears to be a serious and stoic person, similar to Ban, rarely showing compassion for the enemy and not hesitating to kill if necessary. Although he rarely shows it, he cares deeply for his loved ones and is determined to punish anyone who causes them to suffer. His attitude shows that he usually approaches matters and problems in a professional manner.

As Sin, he was shown to be direct in his conversation with Percival and Donny, after saving them from Pellegarde. At first, he showed no interest in Percival as he did not bother to talk to him until he had reason to believe that the boy was one of the Four Knights of the Apocalypse.

Ban

Lancelot has a close and loving relationship with his father. As a child, despite being frustrated by his occasional lack of willingness as king, Lancelot had great admiration for him and always tried to act like a responsible adult in order to gain his recognition and praise.

Currently, despite staying away for years and showing some shame when seen by him, Lancelot still retains his admiration for his father, which is demonstrated when he decides to take the form of a fox and call him "Sin" in honor of him.

Elaine

Lancelot has a close and loving relationship with his mother, being able to talk to her about things he didn't tell his father.

Misty Moon: Lancelot is capable of destroying and disintegrating targets with powerful magical energy. During his fight with Nanashi, part of his magical nature was hinted at when Lancelot absorbed the magical power contained in his "secret technique" that once injured Arthur Pendragon, comparing it to a "river that deals with influences". Magical Energy Manipulation: Lancelot can transform his magical energy into various things, such as weapons. Heart Reading: Like his mother and other fairies, Lancelot is able to decipher the thoughts, memories, and emotions of those around him. His ability seems to be far superior to the other fairies, as he seems to be able to project his own thoughts into the minds of others. Photographic Reflexes: Lancelot, by reading an opponent's mind or an ally's memories of said opponent, is able to reproduce their physical combat styles, without replicating their magic. Transformation: Like her mother, uncle, and other fairies, Lacelot is able to alter her physical appearance. She usually uses it to transform into Sin or a Fairy. Her Transformation appears to be superior to that of other fairies, as she is able to adopt the abilities of the appearances she takes, such as the levitation of fairies or the superior strength of giants.

Spear: When Lancelot was little, he made a spear that seemed to support his magic power well, but Lancelot seems to have lost it after his duel with Tristan. Fairy Bow: A short bow carved by Lancelot from ebony wood, made as light as a feather by King's "blessing", however, in the hands of someone other than Lancelot, it returns to its original weight. Each arrow stored in Lancelot's gauntlet is enchanted and returns to its original length when removed. Lancelot uses this bow as no other weapon can withstand it, however the bow ends up being broken by Nanashi in their battle. Shirojika: Initially stolen from Nanashi's hands by Lancelot to briefly use in combat, Shirojika gives the sword to Lancelot after defeating Nanashi, who gifts it to him in recognition of his strength. Lancelot first mocked the sword after Nanashi called it "blunt", but later expressed surprise and joy upon hearing that it was Dubs' creation.

As the son of Ban and Elaine, Lancelot has had above-average physical and combat skills since the age of 10, with better reflexes than an adult human. At age 10, he was strong enough to almost completely shatter a large boulder with a makeshift spear.

By the age of 16, his physical and combat abilities have improved to the point where he could kill Doronach with a single thrust. During his duel against Arthur, he was able to match him to the point where he was forced to use his Magic. Tristan states that after his "disappearance", Lancelot's power had increased to completely surpass his own, allowing him to match the Seven Deadly Sins.

Lancelot has great speed and awareness, being able to easily track Fiddich and even block him with a simple kick before he can even run. Lancelot also displays great skills in archery, having enough precision to attack the opponent's pressure points with deadly effect.

During his fight against Nanashi, a member of the goddess clan with power comparable to the Four Archangels, as well as handling both his armed and unarmed attacks without injury, Lancelot, as described by Gawain, unleashed a "ridiculously enormous amount of magical power."
