Kirinmaru's powers and abilities
Immense Demonic Power: Being the Ruler of the Eastern Lands and the rival of Tōga, the Lord of the Western Lands, who was regarded to be the strongest demon, in terms of strength, Kirinmaru is an extraordinarily powerful daiyōkai. Even many centuries before, he was already strong enough that he stated he had defeated many powerful enemies through the globe unchallenged and only ever lost to his would-be rival, before growing to match him as the strongest demon in history. He was confident he could kill Inuyasha, an extremely powerful hanyō who had defeated other powerful daiyōkai, and Sesshōmaru even went as far as to banish Inuyasha and Kagome into the Border of the Afterlife rather than allow Kirinmaru to fight them, suggesting he believed Kirinmaru could indeed kill both Inuyasha and Kagome despite their own incredible powers. This was proven to be true when he finally fought them directly, as he was able to effortlessly neutralize their attacks with his terrifying strength, leaving Shippō astounded by his mighty powers, and would have killed them had circumstances not forced him to abandon the fight. During his battles with Sesshōmaru, Kirinmaru proved to be equally matched with his rival's elder son, fighting him to a stalemate twice and even managing to deliver him a mortal injury when he was off-guard at the end of their second fight, and it was only because he was weakened both physically and emotionally in their final fight that Sesshōmaru defeats him, the clash of their powers being such that it caused massive shockwaves and even shifted the weather, causing storm clouds and thunder strikes. During his battles with the hanyō Princesses, Kirinmaru repeatedly proved to be more than a match for their combined strength, easily defeating Towa, Setsuna and Moroha, despite their incredible demonic powers, even when Moroha was using the full extent of her demonic power which rivaled Inuyasha's base strength, simultaneously, and even still defeating them after suffering a noteworthy injury from Riku, killing Setsuna and ultimately besting Towa and Moroha accessing their full powers simultaneously, although not without serious effort and considerable injuries. It has also been shown that his power exceeds that of his sister Zero's, as he was able to overpower her demonic energies contained in the Rainbow Pearls to scatter them across the land despite Zero willing them to return her demonic powers to her. He has displayed excellent control over his demonic energy, capable of manifesting it in various ways and varying intensity, and his power appears to be strong enough to affect the weather and surroundings, as simply his presence was able to cause storm clouds, completely shifting the atmosphere.
Telekinesis: Kirinmaru is able to use his demonic energy for potent telekinesis, as shown by how he levitated and then scattered the Rainbow Pearls across the land by surrounding it with demonic energy with a clench of his fist before waving it wildly, and he could remove a sword impaled on his person by Riku with no gestures and control it to land on his hand and later on summoned his sword back with a meager hand wave. He even casually telekinetically tossed aside Towa. In Episode 37, he uses his hand to steal the Black Pearl from Moroha with a meager telekinetic wave as he tells her to find Akuru's pinwheel or she'll never see her parents again.
Demonic Energy Blasts: Kirinmaru is shown to be capable of releasing powerful energy blasts from his bare hands that were strong enough to easily pressure Setsuna's defenses and even cancel Towa's ability to absorb demonic energy. He could also release a barrage of demonic energy blasts strong enough to injure Riku's eyes. He could also channel demonic energy into his sword without any special technique to release powerful slashes of energy easily able to batter Setsuna and Moroha, even forcing her back to her human form when she was using her full demonic power. He was even able to cut through Setsuna's weapon and critically harm her with a single demonic-energy enhanced slash. He could even dissipate Inuyasha's Backlash Wave with a crescent-like slash and when enraged released such a powerful shockwave of demonic energy that it would have killed Inuyasha, Kagome, and Moroha had Tessaiga's sheath not protected them. He used the same shockwave to get rid of demons in front of the Windmill of Time. While fighting Sesshōmaru the last time, Kirinmaru released a cyclone of demonic energy that forced Sesshōmaru to use his Light Whip to break it.
Demonic Energy Barriers: Kirinmaru could create powerful circular barriers, even when using a normal sword, able to easily negate Moroha's Tenkū no Yabusuma and he also displayed a reflective variant that could reflect her Crimson Backlash Wave. He could manifest such barriers swiftly, as he was able to create one quick enough to block Setsuna's attack moments after knocking aside Towa. Upon tapping into his full power, he displayed the ability to create from his bare hands' powerful demonic shields that were able to stop Towa's Twin Azure Dragon Wave and Moroha's Crimson Dragon Wave and also seemingly use it to lessen the damage when he couldn't dissipate it as well manifest from his sword a large barrier strong enough to eventually repel the slash of Moroha's giant fiery dragon projection.
Aerokinesis: Kirinmaru is capable of manifesting his demonic energy in the form of powerful waves of wind-like demonic energy without even having to move his hands at all, which he can control the intensity of, ranging from simply intimidating the hanyō Princesses and Kyūki and Konton while also opening the door behind them (after hearing them to strike Tōga down from his battle with Ryūkotsusei), to easily dispersing Tōtetsu's demonic smoke and knock him down, as well as shoot down Takechiyo and repeatedly easily ground the hanyō Princesses. He could also release a powerful tornado of wind that were able to easily launch Moroha off the ground and to a considerable distance and knock her out. He was also able to conjure a powerful tornado to carry and lift him into the air.
Pyrokinesis: Like Karan of the Panther Devas of the Panther tribe, Kirinmaru uses his bare hand to incinerate both the Azusa no Yumihari and the Windmill of Time.
Teleportation: Through unknown means, Kirinmaru has displayed the ability to teleport to another location.
Flight: Kirinmaru is capable of levitating himself off the ground and remaining suspended as well as flying through the air at incredible speeds with ease. In Episode 29, Kirinmaru is capable of flight as he took his daughter Rion around the world. He can enhance his flight speed by surrounding himself in demonic energy, to where he was able to reach the time portal when it was moments from closing despite being a noticeable distance away.
Psychic Link: Kirinmaru has a telepathic connection with Osamu Kirin, as he realized that the Grim Comet appeared in the modern era.
Master Swordsman: Kirinmaru proved to be an incredibly skilled swordsman, casually fighting off the assault of Moroha, even when she was using the full power of her demonic heritage to execute powerful melee blows, and easily overwhelming Setsuna and Moroha using their weapons, going as far as to mock them for their inferior combat skill, as well as going toe-to-toe with Sesshōmaru repeatedly in sword fights. He even displayed the ability to use a normal sword with great skill, able to effortlessly defend himself from Towa, despite having been injured by Riku before, and he was able to use his own sword to still outfight Towa with ease. He later easily fought off and pushed back Inuyasha and even casually neutralized a combined attack from him and Kagome by spinning his sword. He also easily outdueled Riku upon drawing his sword.
Master Hand-to-Hand Combatant: Although preferring swordsmanship, Kirinmaru is also an excellent unarmed fighter. He has displayed a noteworthy amount of dexterity and precision in defensive techniques, being able to stop weapons with just two fingers completely and able to use his armored wrists to intercept attacks. He was able to effortlessly overcome Moroha's sword attacks without drawing his sword and even effectively fight off Riku and Rion attacking together solely with his bare-handed skills while holding back to not harm his daughter, repeatedly tossing Riku aside.
Immense Strength: Kirinmaru possessed an enormous amount of physical strength, being able to easily counter Moroha's Sankon Tessō even while only using his armored hand with enough force to toss her aside, and casually block Towa's sword attacks and even easily bruise her with a simple light blow from his sword. He also repeatedly clashed equally with Sesshōmaru, unleashing such force that their sword fight released great shockwaves that rose the tide of the ocean and left considerable pressure on Towa, Setsuna, and Jaken and even shattered the ground with a single blow from his sword. Even in a weakened state, he remained able to effortlessly block attacks from Towa with one hand and was still able to easily overwhelm Towa in a sword lock without really trying to overpower her and even go as far as to comfortably maintain the struggle with one hand while using only two fingers of the other hand to stop Setsuna's Kanemitsu no Tomoe and knock her aside simply by flicking those fingers before tossing Towa aside even as she tried to intensify her demonic power. He even managed to slice through Setsuna's weapon and fatally injure her. Kirinmaru later casually used two fingers from his left hand to catch Moroha's Kurikaramaru while while his right hand holds the Black Pearl as he warned her if she wants it badly, then bring him Akuru and was able to not only still easily deflect Moroha's attacks just by impacting his wrist into her sword but even casually stop her attack by grabbing her in the face and easily throwing her with enough force to injure and somewhat daze her. His strength is able to even neutralize Inuyasha's Kaze no Kizu and Kongōsōha, even with the latter augmented by Kagome's arrow, with pure strength alone and just by swinging his sword.
Immense Speed: Kirinmaru showed vast levels of superhuman speed, being able to move fast enough to form afterimages while easily reacting to and outpacing the attacks of Towa, Setsuna, and Moroha and even go toe-to-toe with Sesshōmaru, also an extremely fast individual.
Immense Agility and Reflexes: Kirinmaru possesses extremely fast superhuman reflexes and agility, being able to easily react to and overcome attacks from highly fast and agile individuals like Inuyasha, Towa, Setsuna, Moroha, and even Sesshōmaru. He repeatedly easily avoided Moroha's sacred arrows, even when his back was turned. Kirinmaru even reacted to Riku and Rion's attacks simultaneously without much effort.
Immense Stamina: He possesses tremendous levels of superhuman stamina to exert himself at full capacity for prolonged periods of time with little strain, being totally unfazed from his fight with Towa, Setsuna, and Moroha and then Sesshōmaru and even remaining fully conscious and able to leave his second fight with them even after fighting Towa and Moroha at their full power despite suffering remarkable injuries whereas they were left unconscious and struggled to walk afterward. Later on, Kirinmaru was shown to be able to easily defeat Moroha, then go on to fight Sesshōmaru, unleash a powerful attack on the girls that left Sesshōmaru near-death, and afterwards was still at peak condition and perfectly able to keep searching for the Black Pearl and later on even fight a fresh Inuyasha, Kagome, and Moroha, all while showing no signs of fatigue despite being pressured noticeably through it all. After having just slightly recovered from his battles, with little rest, Kirinmaru was shown to still retain enough strength to put up a well-matched fight with a fully-healed Sesshōmaru.
Immense Durability and Endurance: Kirinmaru displayed massive levels of superhuman endurance and durability, as he showed little pain and only suffered a slight scratch from Towa's full-strength sword slash to his face. He was even able to survive being stabbed in the side by Riku with only minimum pain, going as far as to casually walk down the stairs with it still embedded in his body while able to talk normally, and still retain more than enough power to effectively fight, even being able to take having it worsened by Towa stabbing him in the same place without much pain, going as far as to be able to still talk and even blast her aside even when she had intensified her attack and took an attack from Setsuna's Blood Blade that broke through his barrier with only a scratch. He was even able to astonishingly take Towa's Twin Azure Dragon Wave and Moroha's amplified Crimson Dragon Wave and survive and still continue to fight until he eventually overwhelmed his opponent. Even his past self was resilient enough to keep fighting after having his left antler cut by his would-be rival and remain conscious after having his hand also cut off and able to fly to his ship only hours later. He also withstood Setsuna's full-force Vermilion Bird Ambush even after being weakened by Moroha's sacred power and Towa's Kyūyōkon-amplified Twin Azure Dragon Wave with only mediocre burn injuries and little pain. Even in a weakened state, he managed to withstand multiple harsh sword attacks from Sesshōmaru and still engage in a final clash of power despite the vicious injuries he suffered, surviving being defeated and blasted by all of Sesshōmaru's demonic energy, though Sesshomaru himself decided not to kill Kirinmaru so as not to hurt the feelings of his twin daughters and require Setsuna to do the job to cut his red thread of fate to finally end him once and for all.
Regenerative Healing Factor: Kirinmaru appears to possess some regenerative factor. Within a matter of days, he was shown to be able to heal from all the damage he suffered from his fight with Towa, Setsuna and Moroha, although some of them remained as scars. He also managed to regrow the hand that was cut off but could not restore his left antler. He also quickly regenerated all the injuries he suffered from the attacks of the hanyō Princesses upon assuming his true form.
Demonic Magic: Kirinmaru is shown to be an accomplished sorcerer capable of making use of rather complicated forms of magic.
Necromancy: He was able to bind Rion's soul to the living world and even forcefully resurrect her by placing her soul into a clay doll to serve as a host body.
Demonic Barrier: Kirinmaru was responsible for the powerful barrier placed on Mount Musubi.
Reality Warping: Kirinmaru was able to manipulate the barrier so as to place Setsuna and Towa in separate pocket dimensions that can only be exited by discovering the right answer.
Vocal Projection: Kirinmaru can project his will through great distances, as shown when he projected his voice to test Towa, Setsuna, and Moroha, and later on appeared in the form of purple shadow to force Rion to her clay doll host.
Zanseiken's curse: Kirinmaru was able to place a powerful curse on the Zanseiken so that anyone who wields it would have their kon sapped away from them until they became lifeless husk in order to prepare the wielder to be Rion's host body.
Natural Leadership: He has great power and authority over dozens of demons from the mainland but especially his top minions, the Four Perils.
Transformation (変化, へんげ, "Henge"): Kirinmaru like Tōga, Sesshōmaru, and Sesshōmaru's mother has the ability to shapeshift between the form of a human and his true demonic form, manifesting horns in his foreheads and transforming his left hand into a green spiky arm.
Longevity: Like many yōkai, Kirinmaru is capable of living for many centuries and remains unchanged even after the birth of Towa, Setsuna, and Moroha.
Spiritual Sight (briefly): Kirinmaru is seen to have the ability to see the spirit of the Windmill of Time, Akuru.
