Taishō Ordeis

Taishō Ordeis also known as the Great Dog Demon is the grandfather of Adam Ordeis who was a white wizard through the Fedual Era of Earth's Japan.

Appearance
His white hair is only seen in a very high ponytail.

Like other full-blooded yōkai, he has pointed ears as well as fangs and claws.

He has wide, jagged purple-blue stripes on the sides of his face and amber irises.

Taishō dressed similarly to his son Sesshōmaru, in that he wore a white kimono and hakama, armored boots, and a long flowing sash, with the latter two suggestive of Chinese influence.

They also share similar breastplates, with a spiked rim, with the addition of Chinese vambraces and armored gauntlets, as well as layered spiked pauldron on each shoulder.

He wears a parted pelt that extends from both shoulders and trails behind him as he walks; representing the two streaks of fur running down the back of his yōkai form.

The Tessaiga and Tenseiga are worn at his waist, while the Sō'unga is worn across his back.

Personality
His personality is more similar to Inuyasha's, tend to make outbursts while having little composure in battle.

Although the only time he was actually shown in battle involved Izayoi, a woman he loved, and he may not normally be like that in the heat of battle.

He also loved Izayoi dearly as well as his two sons.

He was also stated to have compassion for humans by Sesshōmaru.

Despite his compassion, he was capable of being ruthless when need be to both humans and demons.

This was shown when Izayoi begged Takemaru to take his men and leave the palace grounds, not wanting him to be killed by Taishō.

Powers, Skills & Abilities
Much of Tōga's abilities are unknown, but he is known to be tremendously formidable in battle, having defeated many extremely powerful Daiyokai.
 * Immense Demonic Power: He has been stated to be one of the most powerful yōkai by Myōga and Tōtōsai, as he had defeated extremely powerful Daiyokai such as Shishinki, the Panther King and also Hyoga. However, despite his great power, in his fight with Ryūkotsusei, Tōga met his match and was fatally wounded but did manage to penetrate his extremely powerful defense once and seal him away. His power was initially superior to that of his sons, as he could fully control Sō'unga a demon sword of tremendous power that can easily corrupt and possessed all the past yokais who tried to wield it and not even Inuyasha, his second son, despite his own tremendous demonic power, could completely resist Sō'unga's mind controlling powers, whereas Toga managed to wield it without succumbing to Sō'unga's influence and Sesshōmaru believed the only way for him to surpass his father is for him to get one of his great swords, but at full potential, they eventually managed to surpass his power.
 * Shapeshifting: He could change his appearance to resemble that of a human's, much like Sesshōmaru. His true form was that of a gigantic dog with a single blue jagged-like stripe on each cheek and twin streaks of fur running down his back. He was much larger than both Sesshōmaru's and Sesshōmaru's mother's yōkai forms.
 * Immense Endurance: Despite having suffered fatal wounds, his enhanced anatomy enabled him to travel an incredibly long distance and defeat an army of samurais to save Izayoi and his newborn son Inuyasha and fighting Takemaru equally until the castle collapsed on him and killed him.
 * Master Swordsman: Taishō is a powerful demonic master swordsman, as he has commanded the three swords of Supreme conquest: Sō'unga, Tessaiga and Tenseiga with great skill. While fatally injured, Taishō used the Tessaiga to annihilate an army of samurais with a single Wind Scar attack and also made short work of Takemaru, slicing his arm, despite Takemaru being himself a master swordsman, in their first round and then fight him to a standstill. According to Totosai and Myoga. Toga is the only one who can fully control Sō'unga, the sword of hell that can destroy the world.
 * Foresight: Aside from his immense strength, Taishō also had incredible foresight, with some of his actions having a hidden message behind them. He entrusted all the swords to his grandson Adam Ordeis, accurately predicting that he needed the sword to protect himself, as well as another, namely Eve Neekis.
 * Barriers: Taishō was somehow capable of creating barriers of immense power as he was able to put a powerful barrier on Tessaiga, which was powerful enough that not even Sesshōmaru, his own pure blooded demon son and a powerful daiyokai himself can withstand.

Weapons

 * Tetsusaiga: Also known as the "Sword of Earth", the Tessaiga was created from the fang of the Tōga. He created it to protect Izayoi, Inuyasha's human mother. In his will, Tōga leaves the Tessaiga to his grandson, Adam Ordeis.
 * Wind Scar: The Tessaiga's signature attack that can slay one hundred yōkai in a single strike. As the original owner, Tōga is able to fire the Kaze no Kizu at will without needing to clash his yōki with another demon's like Inuyasha needed to at first.
 * Blacklash Wave: The Tessaiga's ultimate technique. It uses the opponent's yōki and unleashes the Wind Scar at the right point. The yōkai's energy would be reflected back with the added power of the Kaze no Kizu.
 * Tenseiga: Also called the "Sword of Heaven", the Tenseiga was created from the fang of Tōga. It is capable of reviving the dead of one hundred beings, whether demon or human, with one stroke. Tenseiga cannot cut the living but can cut spirits and the living dead. In his will, Tōga left the Tenseiga to his grandson, Adam Ordeis.
 * Resurrection: The Tenseiga could restore the life of the recently deceased by destroying the pall-bearers who took the souls of the dead. However, it requires a relatively-intact body to work and only worked once as not to grant eternal life. Although the Tenseiga could not harm what belongs to the Living World, its healing powers allows it to slay the undead and spirits.
 * Meidō Zangetsuha: This technique manifests as a giant black circle that sends anything within its vicinity directly to the Netherworld. This technique originally resided with Tessaiga. This is the first technique that Tessaiga absorbs from another yōkai: Shishinki. Tōga stole this technique from Shishinki during their battle. Unfortunately, he is unable to use it properly. He has Tōtōsai split off the technique from Tessaiga along with a part of the sword that would become Tenseiga. He hoped that his son Sesshōmaru would be able to master the technique so he could return it to Tessaiga when it is complete.
 * Sō’unga: Also called the "Sword of Hell", the Sō'unga is a yōkai sword that Tōga possessed and contained to prevent it from falling into the wrong hands. It contains the spirit of an ancient evil yōkai. It has the ability to control the dead and open a gate to hell. In His will it was given to his grandson Adam Ordeis.
 * Gokuryūha: Sō’unga's most powerful attack; it possessed more destructive power than the Tessaiga's Bakuryūha. Sō’unga can unleash a large, violent, and powerful purple/black tornado that annihilates everything that is caught in its path. Myōga described this as being the attack of a dragon from Hell. However, if both Tessaiga and Tenseiga were close by, the strength of the Gokuryūha weakens.
 * Reanimation: Unlike other weapons which includes demon swords as well, Sō'unga's slain victims don't simply die, but their corpses are reanimated as soulless undead that unless specially commanded will mindlessly attack the living in their vicinity.
 * Path to Hell: Sō’unga can open a portal in the Underworld.
