| Sin - Lancelot

His life is marked by a mysterious disappearance and a drastic increase in power that turned him into the most fearsome rider.
The following is an official timeline of its past:

Age Event / Phase of their Past Key Details
Childhood Hybrid Origin Born in the Kingdom of Benwick, he is the son of the Fox Sin, Ban, and the Fairy Queen, Elaine. He grows up under the tutelage and training of his master, Jericho.
10 years old: Tristan's Party and the Defeat. He attends Tristan's birthday party, where Gowther implants memories of his father's battles into his mind. At the same party, he has a friendly spar with Tristan and is defeated, which changes his cheerful demeanor to a more reserved one.
10 years The Disappearance (The Abduction) Shortly afterwards, while investigating some mysterious disappearances in Britannia with his teacher Jericho, they are both absorbed and disappear without a trace.
10-13 years The Realm Beyond and the Lady of the Lake Although three years passed in Britannia, only 100 days elapsed for Lancelot within an unknown dimension linked to Chaos. There he is held captive by the Lady of the Lake. To survive and escape, he assimilates and absorbs an entire lake of hyperdense, limitless magic, which boosts his power to the level of a Deadly Sin.
14 years The Return (The Edinburgh Grudge) He reappears in the real world displaying a distant attitude and concealing the origin of his new powers. During the Edinburgh incidents, he demonstrates that he has completely surpassed Tristan, easily knocking him out when he loses control.
16 years old The Fox "Sin" and the Riders He adopts the identity of the talking fox Sin on Meliodas' orders to watch over and guide Percival in disguise towards the Kingdom of Liones, formally beginning the prophecy of the Four Horsemen of the Apocalypse.

Transformations and Forms

Detailed Visual Description
Build and Height: He undergoes a dramatic physical growth spurt. His body becomes noticeably tall and slender, with broader shoulders and a lean, well-defined musculature. He acquires the elegant yet dangerous posture that characterized his father, Ban.
Hair: Her hair is bright blonde (inherited from Elaine). She wears it short, but styled in a much more disheveled and spiky way, directly emulating Ban's wild hair.
Face and Eyes: She retains her fine, sharp features. Her eyes are a deep crimson red. On the right side of her forehead, the linear scar that Tristan inflicted on her during a training match in her childhood remains perfectly visible.
Formal Attire: This completely breaks with Britannia's warrior aesthetic. He wears a modern, formal dress suit made entirely of black. It consists of a sharply tailored dark suit jacket, slim-fit black trousers, and a button-down white dress shirt underneath. He wears no armor, demonstrating his complete confidence that no one can touch him.

Detailed Personality

Lancelot's personality stands out as the most balanced, mature, and lethal pillar of the Four Horsemen of the Apocalypse:
• Pragmatic Stoicism: Unlike Ban's boisterous or mocking nature, Lancelot adopts an extremely serious, professional, and direct attitude. He confronts problems head-on without wasting time on heroic speeches or lamentations. If a threat arises, he neutralizes it with cold efficiency.
• Absolute Confidence and Zero Arrogance: He is aware that his power level rivals (or surpasses) that of the former Seven Deadly Sins. Because of this, his demeanor in combat is one of unwavering calm. He doesn't get angry or belittle his rivals with shouts; he simply analyzes them with his calculating mind and acts accordingly, which deeply intimidates the Knights of Camelot.
• Hidden Protective Leadership: Although superficial
