Naraku (奈落 ?, meaning "underworld" or "hell") is the main antagonist in the anime and manga series InuYasha. He is directly responsible for the death of the character Kikyo and the seal placed on the series' protagonist, InuYasha. He is also the cause of most of the troubles and problems facing the other major characters, making his destruction the overall focus of their quest due to the pain he has personally caused them. As half-demon and later a demon, Naraku desires the Shikon-no-Tama, a jewel that would be able to grant him near-invincibility should he acquire all the pieces of it. Although early in the series he desires the jewel to purge his half-human self from his body, after he becomes a full demon he desires the jewel to enhance his strength even further. He is repeatedly opposed by InuYasha and his friends, along with several other characters in the series. Naraku has seemingly countless abilities, many of which may be unknown. Many of his powers are granted/enhanced by the large amount of Shikon-no-tama shards he has. Those that he has revealed are as follows:

Saimyōshō
Naraku's minion wasps from hell. They are useful for stopping Miroku's Wind Tunnel, spying on his enemies, and gathering Jewel shards. Their stings are fatally toxic to both humans and demons alike, but they are rather weak as demons come and are thus easily and numerously slain by InuYasha's group.
Shapeshifting
He can take the form of anything he chooses (usually a humanoid), and change his voice along with his physical appearance. He can also change his body however he wants. This is seen when he fights Sesshomaru in an attempt to absorb him.
Demon puppets
Puppets which resemble him. He controls them from afar and can see through their eyes. They are mostly made of mud and soil, and are able to spring roots in order to attack opponents.
Superhuman strength and speed
Much like Sesshomaru, Naraku is far stronger than a normal demon and can move faster than the eye can see, both in the air and on the ground.
Flight
Similarly to Sesshomaru, Naraku possesses the ability to float midair, and to ride upon a cloud of his own shoki. After his transformation into a full yokai, Naraku never chose to employ his shoki-sustained flight, but flew only by the strength of his will.
Demon parts
As he is made up of multiple demons in one body, Naraku is able to manipulate their body parts at will in order to restructure and strengthen his body, and he can also regenerate himself from injury and reform his body parts if they are cut off. He most commonly uses these parts to form tentacles which he uses to attack.
And many more.

Pegasus Seiya (天馬星座の星矢 Pegasasu no Seiya?, Seiya meaning "star arrow"), also known as Seiya. Seiya is one of the 88 mythical warriors that have served the goddess Athena during ages, protecting justice and peace on Earth, and are known as "Saints, the bringers of hope." As a Saint, Seiya dons one of the radiant and powerful armors of divine origins known as Cloths, his representing the constellation of Pegasus. He also possesses superhuman strength and speed, two of the many extraordinary abilities the Saints draw from their guardian constellations and an inner essence called Cosmo. Although Seiya began his journey as a Bronze Saint, the lowest of three ranks, his abilities gradually grow to rival those of the Gold Saints, the most powerful of Athena's soldiers. He achieves this by awakening his 7th sense, the essence and origin of the Cosmo. Before descending into the realm of Hades, he also awakes his 8th sense Cosmo, allowing him to enter into the Underworld without being subject to its laws.

His most-seen technique is the Pegasus Meteor Fist (ペガサス流星拳 Pegasasu ryūseiken?) which initially allows him to send a large number of punches in a second. Seiya starts this attack at Mach 1 speed, and later develops it to achieve lightspeed for a few seconds. Seiya can combine all his meteors in one punch called the Pegasus Comet Fist (ペガサス彗星拳 Pegasasu suiseiken?). His most powerful technique is Pegasus Rolling Crush (ペガサスローリングクラッシュ Pegasasu Rōringu Kurasshu?), where he grabs hold of his opponent from the back, soars miles into the air, then suicide-dives head-first into the ground. Seiya donning his Pegasus God Cloth.

The Pegasus Cloth represents the Pegasus constellation, which is associated with Pegasus, the divine winged horse from Greek mythology. Seiya defeated 10 other trainees in order acquire the Pegasus Cloth and the status of Saint of Athena. The Pegasus Bronze Cloth suffers damage various times throughout the series, with Aries Mu typically responsible for repairs. In Kurumada's manga, the Cloth changes shape each time it is fixed, with each revision evolving the Cloth into a more detailed form while it remains the same in the anime until the series' second arc. When the Gold Saints use their blood to revive the Bronze Cloths, the second version of the Pegasus cloth can change from bronze to golden hue whenever Seiya charges his Cosmo to the maximum. With the Cloth that Seiya uses in the Hades arc, Seiya is able to use the wings to fly, both normally and through dimensions. In his fight against Thanatos, resurrects in God Cloth state, which was last seen in the ages of myth, further increasing Seiya's Cosmo and vitality.

Eventually, Seiya becomes powerful enough to wear the Gold Cloth of Sagittarius, a Cloth that had lost its true owner before the series began. When Seiya has the Gold Cloth on, his Cosmo is magnified. Nevertheless, while Seiya uses the Sagittarius Gold Cloth many times throughout the series to save Athena from certain peril, he is never officially granted ownership of the Cloth.

Dragon Shiryu (龍星座の紫龍, Doragon no Shiryū?, shiryū meaning "violet dragon") is considered the most matured of the five heroes, and thus the wisest. As the Bronze Saint of the Dragon constellation, Shiryu dons the emerald Dragon Bronze Cloth, a jewel among the Cloths due to its legendary defense properties. Out of all five main characters, Shiryu is known as the calmest and most collected. His sheer physical strength is the greatest of the Bronze Saints, with perhaps the exception of Phoenix Ikki. This is reflected in his ability to have won numerous battles without his Dragon Cloth. Shiryu trained at the Five Old Peaks in China to obtain the Bronze Cloth of the Dragon constellation, and his mentor was none other than senior Gold Saint, Libra Dohko. During his training in Rozan, Shiryu awoke his Cosmo and learned many fighting styles and fundamental wisdom for life, from Libra Dohko. During the Sanctuary Arc, Shiryu awakes the 7th sense in his fight against Cancer Deathmask and later he awoke the 8th sense during the Hades Arc.

His signature technique is Rozan Rising Dragon Force (廬山昇龍覇, Rozanshōryūha?). It is a blow that usually knocks the opponent soaring into the air as an image of a dragon devours him. The power of the Rozan Rising Dragon Force can vary from capable to explosively powerful, depending on Shiryu's Cosmo level at the time of execution. Unlike the favorite techniques of the other Bronze Saints, however, Shiryu's Rozan Rising Dragon Force does have one weakness -- while performing the move, his heart will be left open for a millisecond. Only three people in the series have noted this: his master, Libra Dohko, Bronze Saint Pegasus Seiya and Gold Saint Capricorn Shura.

Other attacks in his arsenal include Rozan Dragon Flight (廬山龍飛翔, Rozanryūhishō?), a straight-to-the-point, jumping attack where Shiryu charges through his opponents with a single fist and Dragon's Kick (ドラゴンの蹴り, Doragon no Keri?), that Shiryu has, to date, used only once, against Cancer Deathmask, in vol. 8 of the manga, and therefore, in episode 39 of the anime adaptation. Shiryu leapt high into the air and dived toward his opponent with a sharp kick to the head. Also, although he has only used it once to date, among his defensive techniques, Shiryu counts the fabled Catch of a real sword's blade (真剣白刃取り, Shinken Shiraha Dori?); the traditional technique used in Japanese Kenjutsu to repel an opponent's sword when unarmed, Shiryu used it to stop Capricorn Shura's attacks as his fists and legs were similar to a razor-sharp blade.

During the Hades Arc Shiryu learns the Rozan One Hundred Dragons Force (廬山百龍覇, Rozanhyakuryūha?). Shiryu learned it from watching his master's battle (although being blind in that moment). It is a technique that appears to be a 100x of the Rozan Rising Dragon Force or the Rozan Dragon Flight -- Shiryu's Cosmo erupts at its maximum, and he ploughs through the enemy with both arms and palms extended. 100 dragons march in the sky as the enemies are destroyed by this energy-based offensive attack.

The final move that Shiryu uses when all else fails is Rozan Enraged Dragon Force (廬山亢龍覇, Rozankōryūha?). It is a kamikaze technique similar to Seiya's "Pegasus Rolling Crush," except while Seiya normally intends to send both himself and his opponent back to the ground, Shiryu will continue to soar into the air and eventually into space -- killing both himself and his enemy. The Rozan Enraged Dragon Force is something that Dohko had strongly discouraged Shiryu from using, even going as far as putting a ban on its use.

After defeating Capricorn Shura, Shiryu is entrusted with the Gold Saint's legendary technique Excalibur (聖剣, ekusukaribā?). It is not a physical sword, but a deadly Cosmo precision focused on Shiryu's right arm. Although Shiryu's version of the sword was not as defined as Shura's (Shiryu's Excalibur lies only in his right arm, while Shura's can be unleashed from any of his limbs), the Dragon later refined it enough to rival Shura's and used it to cut the unbreakable golden spear of Chrysaor Krishna, the powerful Mariner General during the Poseidon Chapter.

Cygnus Hyoga (白鳥星座の氷河 Kigunasu no Hyōga?, Hyōga meaning "glacier") is calm, collected, and unemotional. Beneath the surface, however, he is passionate and devoted to his ideals. As a Saint born under the Cygnus constellation, Hyoga is able to control and manipulate ice and snow as he pleases, as he mastered the basis of the technique of the Saints of ice, stop the atoms of matter by the power of their Cosmo. By increasing his cosmos, Hyoga can freeze objects and people. In his fight against his master, Gold Saint Aquarius Camus, Hyoga awoke the 7th sense and used absolute zero air, being able even to freeze the Gold Cloths, surpassing his teacher. In the Hades Arc, Hyoga was able to use a variation of the Freezing Coffin of his teacher but it was not named.

The Cygnus Saint's favorite technique is Diamond Dust (ダイヤモンドダスト daiyamondo dasuto?), a windy attack that blasts ice and snow at the opponent in a single, concentrated point. Hyoga has used this technique for other purposes, like creating a mirror that reflects certain attacks or performing this attack in the legs of the opponent.

Before learning Aurora Execution his most powerful technique is Holodnyj Smerč (ホーロドニースメルチ Hōrodonī sumeruchi?, Cyrillic: холодный смерч, meaning "ice tornado"; renamed "Aurora Thunder Attack" in the anime). It is the a technique that captures his Cosmo into a single tornado, of which is unleashed via an uppercut. It is a move that, is in essence, a more powerful variation of "Diamond Dust." The "Aurora Thunder Attack" clasps both of Hyoga's hands together as he expels snow and ice at the opponent.

Hyoga learns Aurora Execution (オーロラエクスキューション ōrora ekusukyūshon?) directly from battling his master, Gold Saint Camus of the Aquarius. "Aurora Execution" is a Gold Saint level technique that enables the user to have control over absolute zero, a point where everything becomes frozen. "Aurora Execution" is similar to "Aurora Thunder Attack" in execution.

A minor technique Hyouga possesses is Kol'tso (カリツォー karitsō?, Cyrillic:КОЛЬЦО, meaning "ring" in Russian), with which he creates an ice ring that surrounds and paralyzes the opponent.

Andromeda Shun (アンドロメダ星座の瞬 Andoromeda Seiza no Shun?, shun meaning "twinkle") is arguably one of the strongest characters in the series, although his gentle disposition and kind nature tend to hold him back from using his full power, until he is forced to do so. Shun is also the younger brother of Phoenix Ikki, a fellow bronze saint. Many newcomers to the series have mistaken Shun for a female character, since the Andromeda is a feminine constellation, and the anime adaptation modified Kurumada's original design of the Cloth itself to some extent, to have it appear to have breasts (many were mistaken for years until they were old enough to distinguish the subtle differences). To fight, Shun normally relies on the Andromeda chain, as he does not want to use his full power because he does not want to kill the opponents. During the Sanctuary Arc, Shun awoke the 7th sense in his fights against the Gold Saints. Although a reluctant fighter, Shun is one of Kurumada's characters with the larger technique arsenals at his disposal.
His known techniques are:

Nebula Chain: The Andromeda Saint's signature technique which allows him to manipulate the chains of his Cloth however he pleases. At the most basic, the "Nebula Chain" is a straight-forward attack where the chains rapidly slice and wrap themselves around the enemy. This attack can be improved by using the Thunder Wave of the chain.
Rolling Defense: A simple defensive technique that utilizes Shun's chains in one of two ways: he will either twirl the chains around himself to create a barrier, or set them on the ground to mimic a circular web; this was later named the Circle Defense. In web mode, the chains construct a distance between himself and the opponent, and will discharge energy volts or simply slash the enemy if they attempt to enter the field.
Great Capture: A technique that twists the chains to paralyze, capture, or immobilize foes. Shun also uses other ways of capturing opponents with Boomerang Shoot, Spiral Duct, etc.
Nebula Stream: A defensive attack that links directly to Shun's Cosmo. It entangles the foe with streams of the Andromeda cosmos in an attempt to paralyze them. As Shun becomes more determined to use his true power, the stream will eventually transfigure into the "Nebula Storm" technique.
Nebula Storm: By the time Shun has chosen to execute it, his Cloth and chains are abandoned (either voluntarily or destroyed by his opponent) to allow him full access to his cosmos. The attack is dispelled as a single burst from the summit of Shun's Cosmo. Because of its extreme destructive nature, Shun will only use it as a last resort.

Phoenix Ikki (鳳凰星座の一輝 Fenikkusu no Ikki?, Ikki meaning "gleam") is drastically different from his fellow Saints. He is almost the opposite of his younger brother Shun is calm, soft, caring and very emotional, whereas Ikki is harsh, cold, aggressive, and very much of a loner. Fellow Saint Wolf Nachi once pointed out that it was very hard to believe Ikki and Shun were related due to the extreme difference in their personalities. Ikki's Cosmo is unique to him -- it is full of hatred, anger, incredible aggression and power, but it was still guided by his deep love and loyalty for his younger brother, his friends and loyalty to Athena. Although he dislikes teamwork, he comes to battle whenever Athena's Saints need his help, and is often seen coming in the nick of time to save his younger brother and friends from certain death. This tactic has always been exploited to their advantage, since the enemies are caught by surprise upon meeting/fighting him. He is a noble, complex and mature character, who does not doubt whenever it's necessary to sacrifice his life for his friends.

Ikki is hinted many times to be the most powerful Bronze Saint as he often pitted against the strongest enemies. Like the myth of the Phoenix, his power increases every time he is killed and resurrected. In his battle with Virgo Shaka, Ikki was able to awaken his 7th sense, which placed him in the ranks of Gold Saints in terms of power and skill. He also awakened the 8th sense. As a Saint, Ikki uses two techniques to dispose of his enemies; one deals physical damage, and the other destroys the mind of his foe.

His physical attack is Phoenix's Wings Rise (鳳翼天翔 Hōyokutenshō?), which gathers forces of wind and heat into a concentrated point, then unleashed as a single blow. This attack covers a wide range of distance and it is Ikki's signature move. It may also be used on multiple enemies at the same time. In the manga, the attack is performed strictly with his palms only; in the anime, it is revised to include his fists, although the Phoenix Saint has utilized the original manga form of the technique on several occasions.

His other attack is Phoenix Illusion Demonic Fist (鳳凰幻魔拳 Hōōgenmaken?), which is infamous for destroying the minds of its victims -- the technique is dealt from either a single fist or a finger. Concentrating his Cosmo into his fist to literally destroy his opponent's mind. Once used, it sends various nightmare illusions directly created by the opponent's brain; he or she is trapped within an illusion that is almost indistinguishable from reality. It also considerably weakens ones's control of the Cosmo and depth of perception to reality. Ikki's Phoenix Illusion Demonic Fist usually spells doom for the one in the receiving end -- unless he has an unusually powerful mind or Cosmo, such as a Gold Saint.

In addition to weakening and trapping an enemy in a powerful illusion (followed by instant death) this attack also serves to dwelve deep into an enemy's mind - as was the case when this attack was used on Gemini Kanon during his reign in the Poseidon story arc and many other characters in the anime-only Asgard chapter.

In some battles, Ikki first uses the Phoenix Illusion Demon Fist to paralyze his rival, and then deals the Phoenix's Wings Rise to finish him off.
