Kidō

is one of the four basic Shinigami combat forms, at least according to Captain Sōsuke Aizen.

Kidō is the technique that Shinigami use to focus their Spiritual Energy into magic spells of various powers. These spells serve a wide variety of uses such as healing, defense, or combat.

These spells are graded on a scale of 1 to 99, the latter being the most powerful and the most difficult to perform. In order to use Kidō one must recite the incantation, state the name of the spell, and call its number. For someone skilled enough in a particular Kidō spell, the incantation is not necessary, but reciting it will increase the potential power of the spell. There are three main types of Kidō: binding spells, destruction spells, and healing spells. Binding spells are a broad category referring to anything designed to halt or deter an enemy, destructive spells refer to anything designed to specifically harm an enemy, and healing spells, which do not require names, numbers, or incantations to cast, simply heal the Shinigami's comrades. Even a lower-level Destructive Spell, such as Byakurai, can be utterly devastating when used by a skilled and powerful user. Kido can also be strengthened by certain methods, such as concentration, training, and transformations.

Bakudō
1. — Locks a target's arms in place behind their back.

4. — An energy rope entangles a target's arms.

Incantation: unknown/none.

8. - Creates a round shield that seems to temporarily paralyze and repel whatever strikes it.

Incantation: unknown/none.

9. — Engulfs a target in red light, completely paralyzing them.

26. - Hides the target from sight, presumably by bending light.

Incantation: unknown/none.

37. - Creates a star-shaped cushion of Spiritual Energy, which anchors it to nearby objects with "ropes" of spirit particles. It can stop falling objects, acting like a safety net.

Incantation: unknown/none.

39. — Summons a shield of condensed Reiatsu to block opponents' attacks.

Incantation: unknown/none.

58. — Tracks and locates any spiritual force the user focuses on. To activate it, the user must draw a circle on the ground, cut into four parts with a specific character in each. The incantation animates the circle, causing various numbers to appear within until the specific set is found. The number set seems to be a variation on longitude and latitude.

Incantation:

61. — Summons six thin, but wide, beams of light that slam into a target's midsection, holding them in place.

Incantation:

62. — A rod formed of energy is thrown towards the target before it disintegrates into numerous short rods which are used to pin the target to the surroundings and render them immobile.

Incantation: unknown/none.

63. — Binds the arms of a target. According to Hachigen Ushōda, physical strength alone should not be enough to break out of a level 60 Bakudō, however Kensei Muguruma was able to free himself from this Kidō while in his Hollow form.

Incantation: unknown/none.

73. - Creates a pyramid-shaped barrier around the caster.

Incantation: unknown/none.

75. — Summons five incredibly tall and thick pillars to pin a target to the ground.

Incantation:

77. — Transmits messages to anyone within Soul Society. In addition to reciting the spell, the user must draw specific markings on their arms, which are animated by the spell to convey the messages.

Incantation:

81. — Creates an energy barrier in the form of a rectangular wall. According to Byakuya, it is capable of stopping destructive spells up to #89. This is seen also when Aizen uses it to block Tessai's hado #88. Tessai, at the time, also mentioned that it was a Forbidden Spell.

Incantation: unknown/none.

99, Part 1. — Binds the arms of a target with spiritual fabric and iron shafts.

Incantation: unknown/none.

99, Part 2. — This spell covers a target from head to toe with spiritual fabric (first song), stabs them with numerous metal blades (second song), and then smashes them with an immense metal cube (final song).

Incantation: ''. . .''

Hadō
1. — Pushes the target away from the caster.

Incantation: unknown/none. 4. - The user fires a concentrated, powerful lightning bolt from their finger. Rukia Kuchiki and Byakuya Kuchiki both used this spell and rarely other shinigami as well.

Incantation: unknown/none.

11. - Electric current flows through any object the user touches and is able to lead electricity, damaging any target that is in contact with the object the current runs through.

Incantation: unknown/none.

31. — Fires a ball of red energy at a target.

Incantation:

33. — Fires a burst of blue spiritual energy at a target in a similar manner to 31, but over a wider area and with more power. Another version of this spell has been seen in "Bleach : Heat the Soul 5", used by Byakuya, that send a kind of pinkly attack to the opponent, that looks really like his Zanpakutō, however, we hear Byakuya saying "Soukatsui"(Even if it sound somehow like that "Soukatsuki"))

Incantation:

54. — Fires a blast of purple spiritual energy that will incinerate a target completely when it makes contact.

Incantation: unknown/none.

58. - A widening tornado-like blast is fired towards the target.

Incantation: unknown/none

63. — Fires a massive wave of yellow energy at a target.

Incantation:

63. — Essentially a doubled version of #33, this spell fires two shots of blue fire with greater potency than the single-shot variety. Labeled as 73 in the anime.

Incantation:

88. — Fires a gigantic blast of spiritual energy resulting in an truly enormous explosion.

Incantation: unknown/none.

90. — Forms a box of black energy around a target, which is then pierced by dozens of energy "spears", lacerating the one inside from head to toe. Its appearance and function is reminiscent of a common magician's trick, as well as certain torture devices used during the Spanish Inquisition.

Incantation: unknown/none.

Forbidden Spells

Other
These spells are not explicitly stated to be in one category or the other.
 * — Momo Hinamori uses this spell in conjunction with Shot of Red Fire. Rangiku Matsumoto states that it is number 12, but does not specify whether it is a Destructive or a Binding Spell.


 * — Momo Hinamori uses this spell while imprisoned to knock out a guard and destroy everything within a certain radius of herself.


 * — Tōshirō Hitsugaya used this to seal Momo Hinamori's hospital room. It creates a glass-like barrier which is difficult to break from the outside, but quite simple to break from the inside.


 * — This technique nullifies an opponent's Kidō spell by hitting them with a perfectly opposite surge of energy. Yoruichi uses this against Soifon's Flash Cry.


 * — As the name suggests, the Kidō Cannon is basically a high-intensity energy weapon powered by Kidō. It consists of a crystalline focus point attached to the top of a massive pole, with several smaller crystal structures circling up towards the main one. It is powered by hundreds of Shinigami working in concert, creating an energy blast capable of obliterating a small dimension. The blast forms into several animal shapes which roar just before contact. The power of the blast is such that, in addition to destroying its target, it also causes a small amount of damage to both the human world and Soul Society. Despite its power, it is not a reusable weapon, as it burns into a pile of scrap after being fired.
