— Kitz Weilman to Eren Yeager

The power of the Titans (巨人の力 Kyojin no Chikara^?, also translated as Titan power(s)) allows Subjects of Ymir to transform into intelligent Titans known as the Nine Titans, regenerate injuries, and access the memories of previous Subjects of Ymir that held the power. If a Pure Titan gains the power of the Titans, that Titan will return to being a human.

Description

Transformation

Frieda bites her hand to transform

In order to transform into one of the Nine Titans, a human with the power of the Titans must suffer an injury that draws blood (often self-harm) while having a solid goal or belief in mind at the moment of injury. Being injured by another person is also sufficient. Once the transformation is initiated, a burst of energy is released, followed by the generation of the Titan body and a release of hot steam. After transforming, the human body rests within the nape of the Titan's neck as the center of control. The human body is also merged with the Titan's flesh inside to varying extents, most frequently on the area of the cheeks below the eyes. When a human with the power of the Titans transforms for the first time, they can often lose control of their Titan form and can become a danger to both enemies and allies.

If a Titan form is pushed to its limit, the human will emerge from the nape of its neck, sometimes in a semi-conscious or entirely unconscious state. If a Titan form is not exhausted, then its human form can emerge from the Titan form in full consciousness. In some cases, a human is able to partially emerge from their Titan body without fully leaving the nape. After the power of the Titans is used, oftentimes the area around the emerging human's eyes is marked by dark lines, which resemble the Titan in their possession, for a short period of time.

The ability to transform into a Titan can be hindered by injuries inflicted on the human body. A human can transform into a Titan with injuries as severe as a missing limb, but only if a previous transformation has not occurred recently. If a human emerges from their Titan form and receives a severe injury, this person cannot transform into a Titan again until said injuries have healed.

Eren getting absorbed into his Titan after multiple transformations

Those with the power of the Titans appear to be resistant to the normal absorption that creates mindless Pure Titans. However, this does not mean that they are immune to it. In the case of Eren Yeager, it has been shown that repeated transformations in a short period of time lead to decreased control over the Titan form, as well as diminished Titan size and power. As such, it seems that there is a limitation on how long a human can remain in a transformed Titan state before risking absorption. The length of time spent in a controllable transformed Titan depends on how skilled the human is, although even the most experienced can become incredibly fatigued for as long as several days after repetitive use. The exception to this appears to be the Cart Titan, which is known for its great endurance. Pieck is able to stay in her Titan form for at least two months.

A Titan's transformation usually causes the destruction of the area in which they have transformed in. However, the Colossus Titan is the only known Titan capable of increasing the blast radius to a larger scale than simply the area in which it is located, in which it usually resembles a nuclear explosion. This power was first seen being used by Bertolt Hoover during the battle of Shiganshina District, and later by Armin Arlert to wipe out the naval forces during the Raid on Liberio. The blast was seen by the full district of Shiganshina and city of Liberio, and sent massive waves of energy inland.

Regeneration

Those with the power of the Titans can regenerate their bodies, as long as they have the will to live. They are even able to grow back their entire head. Regeneration from severe injuries such as lost limbs can strain their powers and prevent them from transforming for a period of time; healing takes much longer as a human than as a Titan. The time it takes to regenerate depends on the extent of the injury and how focused the individual is on healing that area. This healing is not absolute, however, and can be overwhelmed if the injury is severe enough. It is also possible to delay the healing, which Eren uses to infiltrate Marley as an injured soldier. The only surefire way to kill a human with the power of the Titans is through severing the brain's connection to the rest of the body, although it is possible to survive even this by transferring the mind to the rest of the nervous system.

Memory inheritance

Those who inherit the Nine Titans are also able to see the memories of previous inheritors to some extent. Armin Arlert says that touching objects or people can help trigger these memories. Blood relations between inheritors play a significant role in passing these memories. Both the Reiss and Tybur families kept their Titans—the Founding Titan and the War Hammer Titan, respectively—within the family, and because of that, they were able to access memories going back by several generations, up to at least the Great Titan War. Other inheritors are shown to be able to see the memories of the previous inheritor at the very least. This process appears to fail when blood relations are interrupted or not present: Ymir and Armin did not receive any memories upon inheriting their Titans, in contrast to the Reiss family who seemingly gained their memories right away. Porco Galliard is unable to see the memories of his brother Marcel possibly due to Ymir being between them in the inheritance line, although Porco could see Ymir's memories. Sometimes, the new inheritor will have dreams of a previous one, such as the case of Armin dreaming of Bertolt Hoover's final moments. The Attack Titan can inherit memories from the future as well as the past.

Curse of Ymir

Kruger during his final year

Each person who gains the power of the Titans is fated with the "Curse of Ymir" (ユミルの呪い Yumiru no Noroi^?), which limits their lifespan to only 13 years after first acquiring it. During the last years of their life, their body will weaken until they perish. Eren Kruger, Uri Reiss, and Tom Ksaver were all sick and appeared to have aged considerably during their final year.

Royal blood

Zeke's "scream" ability is similar to the Founding Titan's

Royal blood allows the "full use of the power of the Titans." This is common knowledge in Marley. Only descendants of the royal family can fully utilize the Founding Titan's powers. Zeke Yeager, a royal from his mother's side, inherited the Beast Titan, but thanks to his royal blood, he can mimic some of the Founder's abilities, such as creating and controlling Pure Titans and even making them move at night using only moonlight; no other Beast Titan had these abilities. Unlike the Founding Titan, however, the control over Titans is not perfect, as one of them had shown some disobedience to Zeke's orders.

Transference

Ymir eats Marcel, gains the power of the Titans, and becomes human

The power of the Titans can be transferred to a new host, should the current host be devoured by a Titan. This allows an ordinary Titan to become human again and possess the power of the Titans, and inherit one or more of the Nine Titans' abilities as well as the memories of the previous inheritors. This has been the case with the Founding Titan for over a thousand years.

However, according to Rod Reiss, the power of the Titans resides within a human's spinal fluid, meaning that to gain the Titan's power, it is not necessary to eat the entire human, but rather a Titan can simply bite through the spine and ingest said fluid. Titan serums are, in fact, the spinal fluid of Titans, though study of the serums is difficult due to the serum's rapid rate of evaporation upon contact with air.

If an individual with the power of the Titans dies before it can be transferred, the power will be passed on to a baby among the Subjects of Ymir, who is born after the said inheritor's death, regardless of distance or relation to the previous inheritor.

Ackerman clan

Main article: Ackerman clan

The Ackerman clan, when awakened, can manifest the power of the Titans in some form without becoming or inheriting a Titan. They automatically gain the combat experience of every Ackerman before them via paths, similar to how memory inheritance works.

Trivia

• In the August 2016 Issue of Bessatsu Shonen Magazine, Hajime Isayama was asked of what is it like to come out of a Titan's body. He stated, "Just think that it's like coming out from a sauna."
• In the November 2018 Issue of Bessatsu Shōnen Magazine, Isayama confirmed that Eren, Reiner, and others do not feel pain if their Titan bodies are damaged.
