Flock

Biodata

Power Progression

Appearance

• Human form: Long black hair, a scar on his right cheek, and a fierce, intimidating appearance 2.
• Giant form: Approximately fourteen to fifteen meters tall, with an enlarged version of his human face, powerful musculature, and visible male anatomy. It lacks Eren’s full-body armor 25 26.

Personality

Flock is pragmatic despite his intimidating appearance. He is the first ko to kneel before Eren and immediately corrects himself when referring to Lhabo as his khal, recognizing Eren as the new ruler instead. He later demonstrates tactical flexibility by identifying a way around Yunkai’s stalled gate assault 2 23 24.

He is attentive to Eren’s preferences and quick to anticipate useful opportunities. He presents Lydia as an interpreter, selects enslaved women for Eren, and saves looted musical instruments because he thinks the king might want them. Eren explicitly values his quick wit when choosing him to protect the Church’s preachers 9 12 35 36.

Flock trusts Eren’s promises because he sees him as a ruler who rewards fulfilled orders, despite recognizing his cruelty and strictness. His desire for Giant power becomes strong enough that he accepts its shortened lifespan. His attachment to women is also pronounced: during transformation training, Modun’s threat that he will lose access to them succeeds where pain and ordinary encouragement fail 16 24 25 26 27.

His treatment of captives is harsh. While guarding religious preaching, he regards those who merely glare at their conquerors as cowardly, believing open resistance would deserve admiration even though it would be punished with death 35.

Abilities & Skills

Screaming Giant Transformation

• Transforms after cutting his palm, producing a flash of yellow lightning 26.
• Initially loses his reason because of the overwhelming sensations of the Giant body; learns to remain conscious through supervised training 26 27.
• Possesses sufficient strength to tear apart Astapor’s damaged gate and force his way through its defended passage 30.
• Transformation and combat consume stamina; exhaustion eventually forces him out through the Giant’s nape 26 27.
• Eren states that accepting the power leaves him fifteen years to live 24.

Screams and Pure Titan Control

• Attraction: His Giant’s screams can summon nearby Pure Titans. This inherent ability attracts them but does not itself grant control 25.
• Command authority: Eren separately permits him to control up to ten Pure Titans. Flock deliberately commands three during the attack on Astapor 25 30.
• Restrictions: He cannot create Titans that obey him. Eren can revoke or override his command authority through the Coordinate 25 26.

Localized Hardening

• Hardens selected parts of his Giant body rather than relying on permanent full-body armor 25.
• Forms armor around his fist to smash Astapor’s gate 30.
• Uses hardened protection while shielding his face and chest; incoming arrows and spears bounce off the hardened crystal 30.
• Eren identifies the Jaw Giant as capable of breaking through these hardened areas 25.

Regeneration

• Rapidly heals the wounds inflicted by Modun’s claws during their first fight 26.
• Produces enough healing steam to obscure Modun’s vision and complicate the attempt to subdue him 26.
• Regeneration does not prevent pain or exhaustion 26.

Command and Tactical Judgment

• Recognizes that Modun can bypass Yunkai’s defended gateway by climbing the wall with his claws 23 24.
• Coordinates with Modun at Astapor by crouching so the Jaw Giant can use his body as a launch point onto the wall 30.
• Helps identify captured Unsullied instructors as a resource for establishing imperial infantry 31.
• Handles prisoner security, reward distribution, military recruitment matters, and reports on captured people and valuables 9 35 61 67 70.

Background / History

Submission to Eren

Flock originally serves as one of four kos in Lhabo’s khalasar, each commanding five thousand warriors. When Eren attacks the camp in Titan form, Flock becomes the first ko to surrender. After killing Lhabo, Eren allows him to retain his position 2 3.

He provides Eren with the khalasar’s strength—thirty-five thousand people, including twenty-one thousand five hundred fighters—and guides him to the former khal’s tent. He then helps organize Eren’s first public Titan demonstration by clearing an open space and gathering the khalasar. Afterward, he oversees the collection and distribution of wine mixed with Eren’s blood 3 4 5.

Rise Through the Imperial Army

During the first raid on Yunkai, Flock brings Lydia to Eren and receives orders to distribute captives and rewards. Eren authorizes him to collect one thousand gold dragons and select two enslaved women for himself. Flock subsequently releases the captured slave masters on Eren’s orders and presents the seized maps 9 10.

At Vaes Dothrak, he joins Colin, Link, and Modun in forcibly escorting the Dosh Khaleen outside to witness Eren’s Giants. After Modun receives the Jaw Giant, Flock also asks for Giant power, but Eren tells him that devotion and battlefield merit are necessary to earn it 13 16.

Earning the Screaming Giant

During the second attack on Yunkai, the cavalry becomes trapped in a costly struggle at the narrow gateway. Flock advises Modun to climb the wall instead, enabling him to attack the defenders and open the gate. Eren praises Flock’s judgment and offers him Giant power, while warning him about its lifespan cost 23 24.

Flock accepts the following morning. His first transformation becomes a rampage, forcing Modun and several Pure Titans to restrain him. Modun’s attempt to restore his awareness by severing his Giant form’s genitals instead triggers an unconscious command that turns the restraining Titans against Modun. Eren overrides Flock’s control and has him exhausted into reverting 25 26.

That evening, Eren supervises another transformation. Pain and shouting fail to wake Flock fully, but Modun’s threat that he will lose his women prompts him to regain consciousness. He then practices fighting and Hardening before the army departs for Astapor 27 28.

Astapor and Captive Security

At Astapor, Flock fights successfully alongside Modun, breaks the gate with hardened punches, and charges through the defenders. After the city falls, the two commanders agree that captured Unsullied instructors should be preserved to train imperial infantry. Flock remains in the city to suppress resistance while Modun presents the proposal to Eren 30 31.

He later protects the nuns preaching to seven hundred thousand captives, organizing the prisoners into seventy areas and watching for resistance. Before the march from Qohor, he warns that Eren’s order to feed prisoners inferior grain could provoke revolt. Eren grants him permission to transform and punish anyone who rebels 35 61.

Duties After the Capture of Pentos

After Pentos falls, Flock presents a consolidated list of roughly one or two hundred captives with silver hair and purple eyes. Eren identifies Viserys and Daenerys Targaryen on it and orders Flock to bring them before him 67.

Flock also supplies a list of unusual plunder containing dragon eggs. In the same meeting, he reports that the year’s young recruits will finish training in two months; Eren instructs Rolo to obtain replacements from him once that training is complete 70.

Relationships

• Eren Yeager — Sovereign, commander, and source of his Giant power. Flock serves him from the takeover of Lhabo’s khalasar onward; Eren rewards his tactical judgment but retains ultimate control over his Pure Titan authority 2 24 25 26.
• Modun — Fellow commander, training partner, and battlefield collaborator. Helps restrain and awaken Flock during his early transformations; later cooperates with him at Astapor 26 27 30 31.
• Colin — Fellow former ko and imperial commander. Shares command responsibilities with Flock until his death during the second attack on Yunkai 3 8 18 24.
• Link — Fellow former ko who rises alongside Flock from the khalasar’s leadership into imperial corps command 3 18 46.
• Lhabo — Former khal. Flock abandons his allegiance when Eren conquers the khalasar and kills him 2.

Notable Quotes

“Your Majesty, I have made up my mind. Whatever the price, I will accept the Power of the Giants so I can better dedicate my heart to the empire!” 25

Trivia

• Flock’s name reminds Eren of the separate character from Attack on Titan, prompting him to retain Flock as a ko and watch for future achievements. The comparison does not establish that the two are the same person 2.
• Eren derives the Screaming Giant from the power known as the Female Titan when inherited from Ymir. He chooses a new name suited to its screaming ability rather than calling Flock’s male form the “Male Titan” 25.
