Ling Yao (姚麟)

• He is the Twelfth Prince of Xing.
• His height is 170 cm (5’7”) (official).
• Despite his royal status, he frequently complains about being hungry because he travels with very little money.
• He possesses exceptional skill in sensing Chi, allowing him to detect enemies that others cannot.
• His bond with Greed becomes one of the most memorable character dynamics in Fullmetal Alchemist: Brotherhood.

Relationship with Greed

One of the most important moments in Ling’s story occurs when he willingly allows the Homunculus Greed to inhabit his body.

Unlike previous hosts, Ling refuses to lose his identity.

Instead, he and Greed develop an unusual partnership, sharing one body while influencing each other’s outlook on life.

Their relationship evolves from conflict into mutual respect, with both learning what it truly means to value others.

⸻

Relationships

Lan Fan

Lan Fan is Ling’s personal bodyguard and one of his closest companions.

She is fiercely loyal to him and repeatedly risks her life for his safety.

Ling, in turn, deeply values her and refuses to treat her as expendable.

⸻

Fu

Fu is Ling’s elderly bodyguard and grandfather of Lan Fan.

He serves as both protector and mentor, teaching Ling the responsibilities of leadership and sacrifice.

⸻

Edward Elric

Ling quickly befriends Edward after arriving in Amestris.

Although they often argue and compete, they come to trust one another and fight side by side.

⸻

Greed

Initially enemies, Ling and Greed eventually form one of the series’ most unique partnerships.

Their shared body forces them to understand each other’s values, leading both to significant personal growth.

⸻

May Chang

Although they come from rival Xingese clans, Ling and May share a common goal of improving Xing’s future.

They cooperate despite their political differences.

Alkahestry

Ling himself is not an alkahestrist, but he is very familiar with Alkahestry, the form of alchemy practiced in Xing.

Unlike Amestrian alchemy, which draws energy from tectonic movements, alkahestry emphasizes the flow of Chi through the land and is especially effective for medicine, healing, and long-range transmutations.

His companion Lan Fan uses this knowledge alongside her combat abilities.

Ling is the Twelfth Prince of the Yao Clan, one of the many royal families competing for the throne of Xing.

Unlike the eldest princes, Ling has relatively little political influence.

Knowing that succession is uncertain, he travels to Amestris in search of the legendary Philosopher’s Stone, believing it may grant immortality and strengthen his position enough to secure the throne.

Although his journey begins as a political mission, it gradually becomes one centered on protecting his friends and changing Xing for the better.

⸻

Xing (Country)

Xing is a vast empire located east of Amestris.

Unlike Amestris, Xing’s medical practices and alchemy developed differently.

The country is divided among numerous noble clans, all of which compete for influence within the Imperial Court.

The Emperor has many children from different clans, meaning succession is determined through political skill, alliances, and merit rather than simple birth order.

This rivalry motivates Ling’s journey throughout the series.

Swordsmanship

Ling is highly skilled with the sword.

His style focuses on:

• Speed.
• Precision.
• Agility.
• Quick combinations.
• Acrobatics.

Rather than relying on brute strength, he overwhelms opponents with fluid movements.

⸻

Martial Arts

Ling has extensive training in Xingese martial arts.

He excels in:

• Hand-to-hand combat.
• Dodging.
• Acrobatics.
• Close-range combat.

Even experienced soldiers struggle to keep up with his speed.

⸻

Chi Detection

Unlike Amestrian alchemists, Xingese warriors are trained to sense Chi (the life energy flowing through all living beings).

This allows Ling to:

• Detect nearby people.
• Sense hostile intentions.
• Track enemies.
• Notice unusual presences, including Homunculi.

⸻

Physical Ability

Although smaller than many fighters, Ling possesses:

• Incredible speed.
• Excellent reflexes.
• High stamina.
• Great flexibility.
• Remarkable endurance.

He frequently performs flips, wall jumps, and rapid evasive maneuvers during combat.

⸻

Intelligence

Ling is far more intelligent than his carefree attitude suggests.

He has:

• Strong leadership skills.
• Excellent tactical instincts.
• Quick decision-making.
• Political awareness.

He understands that becoming Emperor requires more than strength—it requires earning the loyalty of others.

At first glance, Ling appears carefree, impulsive, and almost irresponsible. He jokes constantly, steals food whenever he’s hungry, and rarely behaves the way people expect a prince to.

However, this carefree attitude hides an exceptionally intelligent and determined young man.

Ling is naturally charismatic. He has an uncanny ability to make people trust him, regardless of their background or status. He treats everyone—from common civilians to military officers—with the same level of respect, believing that a person’s worth is determined by their character rather than their social position.

Despite coming from one of the wealthiest and most powerful families in Xing, Ling has no interest in living a life of luxury if it means abandoning those who depend on him. He firmly believes that a king exists to protect his people—not the other way around.

This philosophy defines almost every decision he makes.

One of Ling’s strongest qualities is his loyalty. He refuses to sacrifice his companions for personal gain, even when doing so could bring him closer to becoming Emperor. He sees Lan Fan and Fu as family rather than servants and is deeply affected whenever they are injured because of him.

Although ambitious, Ling’s ambition isn’t rooted in greed for power. He wants the throne because he genuinely believes he can improve Xing and create a future where no clan has to fight simply to survive.

He is also remarkably fearless. Whether facing Homunculi, State Alchemists, or impossible odds, Ling rarely hesitates. Even when he’s frightened, he refuses to let fear dictate his actions.

Another defining trait is his adaptability. He quickly analyzes unfamiliar situations, improvises effective strategies, and rarely allows setbacks to discourage him.

Despite carrying the burden of an entire clan’s future, Ling still laughs easily, enjoys harmless mischief, and often lightens the mood during tense moments. His optimism becomes one of his greatest strengths, inspiring the pe

Ling has a youthful appearance that often causes people to underestimate him.

He has:

• Long black hair tied into a high ponytail.
• Golden-yellow eyes.
• Fair skin.
• A slim yet athletic build.
• Sharp facial features.
• A warm, mischievous smile.

Although he looks elegant, his clothing is often dusty from traveling, and he’s rarely concerned with maintaining a princely appearance while on the road.
Ling wears traditional Xingese clothing.

His outfit usually consists of:

• A sleeveless black tunic with gold trim.
• White trousers.
• Black boots.
• A long white cloak draped over his shoulders.
• Golden ornaments representing the Yao Clan.

He carries a sword at his waist and travels light despite his royal status.
