Only two "true" Kamuis were shown in the anime, Senketsu and Junketsu. A third one, Shinra-Kōketsu, is shown finished in episode 23, though it is presumed that Shinra-Kōketsu is in a new class altogether.
Wearing a Kamui grants the user immense power, compared to that of the Goku Uniforms. These garments have been shown to give the user the power to cause a percussion blast comparable to an atomic bomb. They also give the user enough power to leave craters in the earth and in stone, such as the wall surrounding Honnōji Academy.
Kamui can be extremely dangerous to the user, as in at least one occasion, a Kamui was seen completely disfiguring its wearer, causing the user to go berserk and have a distorted appearance. For this reason, Kamui in their activated state have a signature skimpy appearance to minimize surface contact with the user's skin, which reduces the chance of being overwhelmed by the Life Fibers.
Kamui Senketsu also has the ability to further transform in order to adapt to various situations, enabling abilities such as flight; Kamui Junketsu gained this ability after having some of Senketsu's Life Fibers implanted in it. It is unknown if Shinra-Kōketsu has this ability as well.

A Kamui made by Dr. Isshin Matoi as part of his plan to foil Ragyō's schemes and prevent the Life Fibers from absorbing the planet. Senketsu is unique amongst Life Fiber beings as the only of them that can talk, albeit only to Ryūko Matoi. This was only possible due to Dr. Matoi splicing Ryūko's DNA with Senketsu's Life Fibers when he was making him.
Senketsu showed great sentience and keen intelligence throughout the series, many times giving Ryūko advice on how to approach situations.

A Kamui made by Kiryūin family to be worn by their young daughter Satsuki when she came of age. However, he warned her of the dangers that the use of Junketsu would bring to her body, as unlike Ryuko, Satsuki had no connection or fusion with the Life Fibers in her DNA, being completely human. Some time after this event, and after Satsuki's father's disappearance, Junketsu was sealed away in Kiryūin Manor by Satsuki's mother, Ragyō Kiryūin. Under her orders, Junketsu was kept under tight guard from everyone, even Satsuki herself.
Junketsu has big differences compared to Senketsu, being: the inability to not be able to communicate with its user and the great level of incompatibility with beings that do not have connections with the Life Fibers, causing their desire for blood to maintain its shape be more unstable and violent on awakening.

As it is referred to as "the ultimate Kamui", "Shinra (
