The cursed seals were one of the most frequently-used jutsu of Orochimaru in the series (before he was permanently sealed and incapacitated), which he usually gave to his most powerful and unique followers. To apply a cursed seal, Orochimaru needed to bite his intended target. As he had sharp fangs and an extendable neck, this was a relatively simple task. The seal then appeared on the body of the victim at the point of application, and they subsequently lost consciousness. The design of the seals varied from person-to-person. Sometime later, had the victims survived, they would awaken with the first level of the seal active and be enraged due to the seal's influence. The seals worked by forcibly drawing chakra from the user's body, giving the user a chakra capacity beyond what they would normally be capable of, as well as increased physical performance, especially in battle.

Overview
The seal has two different levels, and the types of transformations differ from seal to seal. When inactive, the seal is simply a black tattoo on the user's body. Orochimaru has a wide array of cursed seals, so the appearance of the seal will usually vary from user to user. Each seal always has three identical marks arranged in a circular pattern. When first activated, the marks on the seal glow and replicate, spreading over the user's body. This is known as the of the seal. The degree to which this occurs is dependent on the user, and the degree to which it spreads is proportionate to the overall effect it has. Normally, the wearer of the seal will also experience slight pains during the activation of this level.

The of the seal causes the black marks to completely envelop the user. This is followed by an unnatural alteration of the user's body, with the only common features being yellow eyes with a black sclera, skin changing color, and longer hair. When in this level, the seal eats away at the user's mind and personality, driving them to madness if used too long. It also takes quite a toll on their body, since they are being mutated by the seal. Aside from the first and second levels of the seal, skilled users of the seal are able to perform partial transformations in which the aforementioned mutation caused to the user's body in the level two state can be used without altering the entire body. The power of the cursed seal can even synchronize with the user's regular body with extended use, increasing the stats of their normal state for a short time. .

Because the seals forcibly draw chakra from the user, they will often kill the user when first applied. Orochimaru has averaged a ten-percent success rate when applying these seals. Additionally, even if the user survives, their body will not be able to easily control the power of the seals given to them. To compensate for this, Orochimaru developed the Mind Awakening Pill. The drug forces the user's body to become accustomed to the unnatural increase in power, but also kills the one who takes it. The sealing jutsu Four Black Fog Battle Formation and Dark Sealing Method are used to keep the drug from killing the user by placing them in a temporary death state.

Orochimaru originally developed the cursed seals through experimentations on a man named Jugo, whose body naturally produces an enzyme that triggers a state, on which the cursed seal is based. The difference between Orochimaru's seals and the unrefined enzyme are the effect that they have: while the cursed seal is controllable, the unrefined enzyme, extracted from Jugo, produces uncontrollable rage and madness in those exposed to it, including Jugo himself, and the effects cannot be controlled. Similarly, Jugo is not limited to a single transformation, and can change the advantages of his form to fit the situation.
