Titan

Biodata

Origins and History

Arthur initially learns that Titans are man-eating creatures that nearly exterminated humanity. According to the history known within the Walls, the survivors built three fifty-meter defenses—Wall Maria, Wall Rose, and Wall Sina—roughly a century earlier and survived under their protection 3.

Grisha Yeager’s diary overturns this understanding. Its account traces Titan power to the ancestral Ymir, who supposedly obtained it through a pact with the devil. After her death, that power divided into nine Titans. Their inheritors established the Eldia Empire, which conquered other countries before Marley exploited internal conflict, seized seven Titan powers, and overthrew Eldia 127.

The Titans roaming Paradis are transformed Eldians, many of them dissidents punished and exiled by Marley. Injecting Eldians with Titan spinal fluid turns them into Pure Titans. Grisha’s first wife, Dina Fritz, and his fellow Restorationists suffered this fate, while Grisha escaped through the intervention of the Owl 127.

Classification

Appearance

• Variable size: Observed Titans include a three-meter individual, seven- to fifteen-meter classes, and the Colossal Titan towering above a fifty-meter Wall 15 44 88.
• Uneven proportions: Some have unusual builds, such as a short Titan with an abnormally large head 88.
• Distinctive inherited forms: Eren’s Titan has long black hair, pointed ears, green eyes, and a muscular body; the Beast Titan is covered in hair 58 68 90.
• Exposed musculature: The Colossal Titan appears skinless and blood-red, with steam pouring from its body 15.

Abilities & Skills

Physical Strength and Combat

Titans can crush buildings, tear bodies apart, and carry immense loads; trained human users can also apply martial arts through their Titan bodies 46 58 59 95.

• Eren’s Titan destroys another Titan’s head with one punch and tears off an arm to use as a weapon 45 46.
• At Trost, Eren carries a massive boulder to seal the breached gateway, although its weight severely limits his speed 59 60.
• Annie retains her recognizable fighting stance and kicking techniques as the Female Titan 76.
• Eren uses grappling holds taught by Arthur to restrain Reiner and crack the Armored Titan’s exoskeleton 95 96.

Regeneration and Steam

Titan power allows injuries to heal, including wounds sustained by human holders outside their Titan forms 63 68.

• Eren’s injured hands continue healing even when he cannot deliberately transform 68.
• Annie attempts an escape while her limbs are only partly regenerated 85.
• Levi leaves blades embedded in the Armored Titan’s eyes to delay their recovery 95.
• Titan corpses evaporate, leaving skeletal remains during their breakdown 88.

Human Transformation

Human holders can generate full or partial Titan bodies. Eren’s transformations frequently follow self-inflicted injuries and are accompanied by golden lightning, smoke, or steam 58 68.

• Purpose matters: Repeated hand injuries fail to trigger Eren’s transformation during an experiment, but reaching for a dropped spoon produces an incomplete Titan body. Arthur identifies a clear goal as the missing condition 68.
• Control requires practice: Eren initially loses reason and attacks Mikasa. Armin restores his awareness during the Trost operation; later training allows him to transform without losing control 58 59 72.
• Stamina limits use: Exhaustion prevents Eren from transforming again after sealing Trost’s breach. Research nevertheless establishes that repeated transformations are possible when sufficient stamina remains 61 79.
• The human occupies the nape: Eren is found there after his first battle and later emerges from it deliberately 48 80.

Inheritance, Memories, and Lifespan

A Pure Titan that eats a human possessing Titan power can return to human form and inherit that ability 108.

• Ymir gains her power after consuming one of Reiner’s companions while wandering as a Pure Titan 108.
• Eren’s recovered memories show his younger self being injected, transforming, and eating Grisha 110.
• Rod tells Historia that consuming Eren would give her the Founding Titan and access to Frieda’s memories 111.
• Titan-power holders face a thirteen-year lifespan limit. Arthur bypasses ordinary inheritance by devouring Ymir’s Jaw Titan power without killing her, leaving her human and free of that limit 142.

The Nine Titan Powers

Grisha’s diary describes nine inherited Titan powers. Eight are named in its supplied enumeration; the Female Titan is separately identified throughout the story 82 127.

Founding Titan Activation

• Eren first awakens the Coordinate after striking the blond Titan during the retreat from Reiner and Bertolt 100.
• He later recognizes that Titan as Dina Fritz, whose royal blood explains the temporary activation 128.
• Zeke proposes combining his royal blood and Titan power with Eren’s Founding Titan. Eren publicly confirms his earlier contact with Dina when supporting this proposal 134.
