William J. Moriarty

Appearance

• Blue-black wavy hair that falls to her shoulders and blue eyes
• Wears a classic suit - shirt, jacket and trousers
• Short stature and thin build

Character

Little Sherlock lacks the analytical sparkle in his eyes. He's deprived of his sharp mind and remembers practically nothing about himself except his name—a side effect of his transformation. He's mischievous and very loud, which irritates others. So, his personality doesn't change with his age; he remains just as unbearable.

Lewis, if he meets Sherlock in the mansion, immediately winces with displeasure and disgust.

Albert treats Sherlock calmly, even condescendingly, just like William

Appearance: Light-blond (possibly ash-blond) hair, scarlet eyes (like William's), and glasses. He has a burn scar on his right cheek, which he inflicted on himself to fake his death in a fire.
Personality: He is unquestioningly loyal to William and willing to fulfill any request he makes, no matter how cruel. He is the coldest and most emotionless of the brothers; he was sickly as a child, but as an adult he displays ruthlessness. He manages the estate and is a good cook. He strongly dislikes Sherlock Holmes.

He is shown as an elegant and well-mannered aristocrat, which emphasizes his noble origin.
Personality: Calm, collected, and insightful. Sympathetic to commoners and strives to eliminate class inequality. Cold-blooded and cruel toward aristocrats, not hesitating to commit murder (often at the hands of others) to achieve his goals. For the sake of his brothers, he murdered his own family and burned down their mansion. He serves in the British Army with the rank of lieutenant colonel.
· Interesting: He enjoys knitting, but is a poor cook.

Appearance

Blonde hair, parted on the sides. Blood-red eyes. Wears classic Victorian-era clothing.

Character

🕊️ An Idealist with Cruel Methods: William sincerely strives to eliminate class inequality in Britain, but his methods are radical: he becomes a "crime consultant," cold-bloodedly murdering aristocrats who oppress ordinary people. In this, he acts as an antihero or even a well-intentioned extremist.
· 🎭 Dual Nature: In public, he is a charming mathematics professor, radiating calm and kindness. However, when committing crimes, his true face changes, a sadistic expression appears, and his actions become cold-blooded and cruel.
· 🧠 Brilliant Strategist: His intellect allows him to plot the perfect crime without leaving any clues and manipulate those around him, including Sherlock Holmes and even the British government. He is capable of calculating situations many steps ahead.
· 🥀 Deep Guilt: Despite his outward calm, William suffers remorse for the murders. At one point, he even plans to sacrifice himself to unite the upper and lower classes in the fight against a common enemy—himself.
· 🤝 Loyalty and Charisma: He genuinely cares for his brothers and allies, who reciprocate his unconditional loyalty. His charisma and conviction inspire people to follow him.

While some critics have found his character underdeveloped and called him "perfect" (Gary Sue), it is his moral ambiguity, his internal conflict between ideals and reality, and his cold calculation that make him a memorable character in this unusual reimagining of a classic story.
