A Quirk (個 (こ) (せい), Kosei?, lit. Meta Ability (異 (い) (のう), Inō?, lit. Along with being unique to each user, Quirks are sorted into multiple categories. Quirk users are also limited to only developing one ability and are thus unable to achieve any other through natural means. The first Meta Ability was manifested by a newborn baby in Qing Qing City, China with the ability to radiate light from its body. cause of this phenomenon is unknown, it has been theorized that it was caused by the spread of a previously unknown virus carried by mice, although this theory had no hard evidence. The advent of the Quirks led society into chaos. The dawn of this extraordinary era was marred by a breakdown of society caused by the sudden onslaught of criminals empowered by their newfound "superpowers" and ordinary people being prejudiced against the new minority. As chaos and unrest ensued due to the outbreak of Meta Abilities, ordinary civilians decided to take matters into their own hands to bring order to society, and thus the first "heroes" appeared in the form of Vigilantes, beginning the Vigilantes Era.
The era of vigilantes. During this time period, All For One became a symbol of unity in society. He used his own Meta Ability to remove Meta Abilities from those who did not want them and give them to those that did. His actions under the guise of returning society to its prior state of humanity, when in reality, he was gathering followers who were loyal to him, allowing him to act out his ulterior motives. At some point, a woman gave birth to a son named Chikara Yotsubashi. As Chikara grew up, he faced a lot of discrimination and abuse for having a Meta Ability. His mother supported him, stating that her son's Meta Ability is just a Quirk of his. Although at the time, her message was scorned and even led to her murder, decades later, "Quirk" became the most common term for such Meta Abilities, and she retroactively became known as the Mother of Quirks. As society adapted to the new status quo, the Police Force moved to prioritize leadership and to maintain the status quo, and as such, decided not to use Quirks as weapons. To fill that void, the profession of crime-fighting Quirk users, Pro Heroes, began to exist, starting in Rhode Island, USA, which caused the Vigilantes to slowly disappear. Authorizing the use of powers that could so easily kill, however, was a greatly criticized decision at first, but eventually became accepted as a legitimate occupation.
With the proliferation of Quirks, the government began to regulate their use.
This became known as the "Advent of the Extraordinary". Destro preaching on using the Quirks freely. With the proliferation of Quirks, the government began to regulate their use. A group of Quirk users known as the Meta Liberation Army, led by Chikara under the alias, Destro, had tried to stop the passing of regulations that would restrict Quirk usage, believing that free use of Quirks is a basic human right. They rebelled against the governments of a number of nations for several years before ultimately suffering defeat. Currently, roughly 80% of the people who make up the global population possess a Quirk, and that percentage continues to increase. According to Yoichi Shigaraki, the number of individuals without a Quirk has been rapidly declining in population, indicating that now less than 20% of the world's population is Quirkless. Quirks are said to be the next stage of evolution in the human race. It is possible, though rudimentary, to diagnose a person as possessing or lacking a Quirk by analyzing the presence or absence of an extra joint in their pinky toe. People with only one joint tend to develop a Quirk, while having two joints usually indicates that the person is Quirkless. The lack of the extra joint makes a person's body more "streamlined", a secondary aspect of human evolution brought about by the emergence of Quirks.
Eijiro Kirishima's Quirk first manifesting as a child. Luminescent Baby. Although, there are late bloomers who don't develop their power until a bit later in life; one such example is Tenko Shimura, who didn't develop his Quirk until he was five. Additionally, Izuku Midoriya was able to explain his use of One For All by claiming he was a late bloomer; though he was lying to protect the secret of his Quirk, this does suggest that it is also possible for someone to not develop their Quirk until their teenage years or perhaps even later. A Quirk's manifestation tends to happen very suddenly, often to the child's surprise. Eijiro Kirishima's Hardening Quirk first manifested in the middle of the night when he needed the toilet, and in one of his hands accidentally cutting his right upper eye. That said, there can be precursors to a Quirk manifesting as well, such as Tenko Shimura feeling a sudden pain in one of his arms the evening before his Quirk fully manifested. While Quirks are unique from person to person, some powers are more common and widespread than others, such as fire or water manipulation and the power to grow to gigantic sizes.

On the other hand, Quirks such as spatial warping and regenerative healing are very rare. Furthermore, not all Quirks are singular abilities, as there are some that can have multiple powers. Kaina Tsutsumi's Quirk allows her to protrude a rifle from her right elbow, but she can also mold pieces of her hair like epoxy putty and shape them into any kind of bullet. Tsuyu Asui's Frog Quirk gives her the physiology of said creature, granting her the many abilities of a frog such as an extendable tongue, great leg strength and leaping ability, camouflage, etc. In rarer cases, a single Quirk can take the form of multiple abilities that are completely different from each other, giving the impression of having more than one Quirk; Shoto Todoroki possesses a Quirk that is a perfect combination of his father and mother's fire and ice powers respectively, essentially giving him two Quirks in one. It is even possible, albeit quite rare, for some Quirks to take the form of sentient beings that are connected to their users. Fumikage Tokoyami's Dark Shadow grants him a dark creature that lives inside his body which is capable of speaking and acting by itself, even going against its own user's command on occasion. Rody Soul's eponymous Quirk gives him a small bird-like companion named Pino who acts based on his innermost feelings. Shoto's overuse of his Quirk gives him frostbite. Quirks are extensions of a person's bodily functions.
39;s tolerance for high heat, causing him to easily get burned by his own flames.
As such, they can be trained and worn out. When a person works out their muscles, the muscle fibers are destroyed and new, stronger ones grow back; this same rule applies to Quirks. However, should a Quirk be overused, the user could suffer any of a variety of drawbacks, depending on the nature of the Quirk. These drawbacks are usually simple ailments, such as dry skin or nausea; however, in some cases, the drawbacks can be much more severe. The body of a Quirk user has natural adaptations to protect itself from any damage the Quirk might do to them without these natural defenses. For example, someone who can breathe fire does not burn their mouth when using their abilities. However, there are instances where a Quirk doesn't suit the user's body and the body can't handle it. Such conditions can be bypassed through the use of support equipment, such as Yuga Aoyama's belt. Some people simply have a body that is not properly suited for their Quirk, Toya Todoroki for example inherited his mother's tolerance for freezing cold, rather than his father's tolerance for high heat, causing him to easily get burned by his own flames. Some people, such as Nine, have a Quirk that is simply too powerful for the human body to handle, causing them to suffer a massive strain on their body, resulting in chronic pain, cellular degeneration, and even a significantly shortened lifespan.
Young Himiko fascinated by gore due to having a blood-based Quirk. Quirks are known to have a direct influence on the user's personality. For example, Himiko Toga, whose Quirk allows her to transform into a lookalike of anyone whose blood she drinks, caused her to have an obsession with blood and gore, even when she was a child, as well as an unyielding desire to become like the people she admired. While a Quirk's influence on personality can cause the user to have trouble fitting in with others, it does seem to allow the user to use their power more naturally and effectively; Himiko's obsession with blood allows her to use her Quirk and drink blood without feeling disgusted, and without her conscience getting in the way. Another facet of Quirks is that they are affected by the user's emotions, given that they serve as a part of their physiology. This applies to some Quirks more than others, such as Blackwhip being empowered by intense emotions such as anger and hatred.
The term Quirk Factor can also be used to refer to the part of ones body that utilizes the Quirk.
Some Quirks can even be based on certain emotions entirely, such as Manami Aiba's Love, which allows her to grant a power boost to the person she loves by confessing her feelings to them. Quirk levels can be measured, though only Toshinori Yagi's have ever been shown, being at 15,000 AP at his peak and reaching a low point of 2,500 AP in the present. Queen Bee, a parasitic bee with a Quirk that allows her to control a hive mind of other bees as well as possess the bodies of individual humans. Every Quirk contains an echo of the consciousness of its wielder; if a person's Quirk is transferred to someone else, the consciousness of the previous wielder will appear in the new user's mind, either as voices in dreams or manifestations in a mental mindscape. This phenomenon is compared to cases of people whose personalities and tastes changed after an organ transplant. If further transferred to yet another new user, then that new user will experience the consciousnesses of all of the previous users. Though, these consciousnesses will disappear if the new user loses the transferred Quirk., Kosei Inshi? Quirk. This includes the primary Quirk power, as well as all the biological mechanisms that allow said primary power to function properly. The term Quirk Factor can also be used to refer to the part of ones body that utilizes the Quirk. For example, Katsuki Bakugo can sweat nitroglycerin-like liquid from his palms and ignite it on command, so his Quirk Factor is in the palms of his hands.
Under special circumstances, a second Quirk can be added to a person's genetics. However, gaining multiple Quirks often puts immense strain on the inheritor, rendering them as mindless living dolls incapable of speaking. It was initially believed a person can tolerate two Quirks at most, should they be physically fit, as was the case with the One For All users, but it turns out they too suffered from the backlash of carrying two Quirks, which Dan in a significantly decreased lifespan. Presently, there are only three known people who have been able to wield multiple Quirks without suffering from this Quirk overload, All For One, Gigantomachia, and Izuku Midoriya, and three who have been able to achieve this feat through heavy modifications on the body and mind, Number 6, Nine, and Tomura Shigaraki. It is potentially possible that a Quirk that can heal the body or provide more energy to the user can supersede the negative effects of holding multiple Quirks, as seen through Gigantomachia's Endurance, Tomura's Super Regeneration, and Nine's attempt to claim Cell Activation.
