Titan

Biodata

Classification

Military instruction divides Titans into ordinary and abnormal types. The instructor cannot confidently classify the Colossal and Armored Titans, whose characteristics fall outside established records 23.

Anatomy & Behavior

• Humanoid bodies: Titans resemble enormous humans, though some have distorted proportions, oversized jaws, or unusually long limbs 1 2 45.
• Human-directed feeding: Military lessons state that Titans show no interest in species other than humans. They have no excretory organs, and their source of energy remains unknown 23.
• Nighttime dormancy: Ordinary Titans sleep deeply at night unless disturbed by a powerful stimulus 23.
• Body heat: Titan blood is scalding. The Colossal Titan releases steam hot enough to threaten soldiers approaching its back 43 46.
• Evaporating remains: Dead Titans dissolve into steam, including their bones. Yago’s abandoned Titan bodies disappear in the same way after he exits them 1 18 47.

Intelligence

Military doctrine holds that Titans lack intelligence and that Abnormals are merely stronger exceptions. Observed behavior complicates that position 23.

• An Abnormal Titan hides beside a road, ambushes Giso’s wagon, and later catches Vig’s mobility-gear cable 2.
• The Colossal Titan deliberately destroys Trost’s fixed cannons, leading Eren to recognize its intelligence 43.
• Yago consciously controls his Titan’s movements, shares its vision, and remains aware of his human body inside its nape 18.
• The pointy-eared Titan attacks other Titans rather than the soldiers at the supply station. Yago believes it contains another human, while Connie calls it an Abnormal 50.

Abilities & Skills

Physical Strength & Mobility

• Titans can seize, crush, and devour humans; even a three-meter Titan can kill an elite soldier who makes a mistake 2 23.
• Abnormals can outrun ordinary horses. One encountered in Trost leaps more than ten meters into the air 23 46.
• Yago’s Titan punches through a large tree, kicks another fifteen-meter Titan in half, and uses an over-the-shoulder throw against an Abnormal 2 3 18.
• During the battle of Trost, the Fate Titan defeats nearly forty Titans, including seven or eight Abnormals, before sustained combat begins exhausting Yago 47.

Regeneration

• Severed limbs rapidly regrow. Military instruction identifies destruction of the nape as the only known way to kill a Titan 23.
• A head shattered by cannon fire can regenerate completely within two minutes 24.
• Titan Power also heals Yago’s human body: his crushed legs recover during an incomplete transformation, and an arm injured by Kenny subsequently heals 6 36.
• Exhaustion reduces regeneration speed, as Yago observes in the pointy-eared Titan 50.

Human Transformation

Yago provides direct evidence that a human can become a Titan while remaining inside its nape 1 18.

• His documented transformations involve injured palms, yellow lightning, and the rapid formation of bones, muscles, blood vessels, and other tissues 2 6 31 47.
• Transformations can be incomplete. While gravely injured in Shiganshina, he produces a skeletal body that stops forming halfway 6.
• Secret experiments improve his control until he can perform a complete transformation. Later testing establishes an approximate two-hour duration, shortened by fighting 8 18.
• Titan Power enhances his human strength and perception. After winter training, he experiences a further major increase in physical strength 8 32 33.
• Yago suffers recurring annual pain and once loses control, transforming into a partially formed Titan before Lucia’s voice helps calm him 14.

Weaknesses & Countermeasures

History

Humanity’s Retreat

According to the history explained to Yago, Titans appeared roughly a century earlier and drove humanity close to extinction. Survivors established Wall Maria, Wall Rose, and Wall Sina for protection. The Survey Corps subsequently ventured beyond the walls to investigate Titan origins and seek a means of defeating them 2.

An earlier breach was caused by a Titan Cult that opened a gate to admit a ten-meter Titan, leaving roughly five thousand people dead or injured. Kuklo killed it using Omni-Directional Mobility Gear, establishing humanity’s first Titan kill with the equipment 34.

Shiganshina & Wall Maria

The Colossal Titan destroyed Shiganshina District’s gate, allowing Titans to flood the streets. Yago secretly used an incomplete transformation to save Lucia and Carla. The Armored Titan then breached Wall Maria, forcing survivors to retreat toward Wall Rose 5 6 7.

Battle of Trost

The Colossal Titan’s appearance at Trost brought another invasion. Titans overwhelmed the Garrison vanguard and stranded surviving soldiers without supplies. Yago fought both in human form and as the Fate Titan, while the pointy-eared Titan’s attacks on other Titans helped the cadets reach the supply station and replenish their gas 43 47 49 50.

Unresolved Origins

• Human connection: Yago suspects that ordinary Titans were once humans and that the Colossal and Armored Titans are human-controlled forms. His own transformations are confirmed, but these broader explanations remain his deductions 17 23 43.
• Yago’s creation: Fragmentary memories show a white-coated figure calling him a creation and referring to Marley. Yago suspects he was modified into a weapon capable of controlling Titan Power 14 30 40.
• Founding Titan: Reiner and Bertholdt seek information about the Founding Titan. Reiner proposes another attack to draw its attention, but its abilities are not explained in these passages 26 41.
• Energy source: Yago wonders whether daylight supplies Titans with energy because ordinary Titans become dormant at night. This remains speculation rather than an established explanation 23.
