Personality
Sesshomaru born of a great demon bloodline, possesses the perfect power that many demons desire. Because of this he is always composed and confident in his power. His air of aloofness and indifference is a product of dignity that only one of such rare demonic power may possess. Sesshomaru is more or less emotionless; only anger, annoyance, and dissatisfaction showing on his face. Because both his heart and body are so strong, he had no desire whatsoever for the Shikon Jewel. He had absolute confidence in his power, so he did not need the Shikon Jewel and doesn't have to conspire with allies. Sesshomaru even responded sarcastically towards Naraku, who had assumed an air of impudence due to his increased demon power. In battle he judged his enemy's power level and attacked with the minimum power necessary. He dealt with his enemies after determining their power. Once he had realized their weak point, their attacks were futile.
Sesshomaru is obsessively proud of his father the Inu no Taisho, of whom the whole demon world was in awe. Because he respects his bloodline so much, he despises Inuyasha as well as Inuyasha's human mother Izayoi. He insults Naraku, who tried to take advantage of Sesshomaru's power. All that his father left him was a dull sword that wouldn't cut anything. Anger welled up in his heart for not being able to use Tenseiga, which was left by his father, whom he highly respects. Sesshomaru held resentment towards his father for having left Tessaiga to Inuyasha, whose power was weaker than his own. However, over time, Sesshomaru comes to grasp why his father gave him Tenseiga and lets go of his disgust towards his half-brother, even showing concern for him in rare moments. He was also secretly angry that Naraku, who was assembled by demons far lower in level than Sesshomaru, used abusive language and disrespect towards him.
Sesshomaru had stated that he seeks to only fight the strongest beings alive and how he had wanted to fight his father and defeat him. Sesshomaru felt nothing for others, sneering and dismissing humane feelings. Anyone in his way is an enemy whom he will exterminate without hesitation. He does not hold back his power, even against women. He rationalizes that all his prey is the same and defeats them accordingly. For one with such pride in his power, cooperation is proof of weakness and being alone is a condition for the strong. Once he judges someone as an obstacle, he is quick to kill without hesitation. He used to feel nothing for anyone, but meeting various people, such as the ever-changing Inuyasha, Naraku with his numerous proposals, and all-alone Rin had brought change to his heart.
After he saved Rin and became a true owner of Tenseiga, he started to show feelings behind his heartless and cruel words. He stopped the demonic Inuyasha's wildness by controlling his power and he looked at him like an older brother reprimanding a younger brother, though claimed he would kill Inuyasha despite his actions showing the opposite. He even refrained from killing Kohaku when he could easily do so, when he looked in his eyes and saw emptiness and that he had given up everything. Sesshomaru has a very inquiring mind when there is something he cares about, but at the same time, he had almost no tenacity of purpose. If he becomes interested in something else, he will arbitrarily turn his back on what he's doing, even during battle. Just like his fighting style, he is quick to make decisions and act on then immediately.
The encounter with Rin awakened him as the true user of Tenseiga. The smile and fleeting life of this young girl who tried to save him caused Sesshomaru to change for the first time. The will of his father, who cared for humans, has finally been passed to his oldest son. Sesshomaru used to leave anything behind that might bind him but he has slowly but surely changed. Sesshomaru genuinely cares about Rin and Jaken and while he rarely shows it, he does appreciate their loyalty. Sesshomaru originally held much contempt towards protecting the weak, seeing it as a waste of time and ridiculous. Unlike the Inu no Taisho and Inuyasha, Sesshomaru has trouble admitting he had people to protect (Rin and Jaken) and out of pride, would never admit that he does. Another trait of Sesshomaru is one he shares with his younger brother. Both have tempers and are very easy to annoy (Inuyasha being loud in his anger, Sesshomaru being subtle) as he has been known to hit Jaken when he says something that displeases him, similar to how Inuyasha is with Shippo.
Abilities
As a full blooded demon, Sesshomaru is overwhelmingly powerful, being a match for any opponent he encounters. He has exhibited senses much more powerful than that of humans and even many demons and a plethora of powerful techniques at his disposal.
Flight
Sesshomaru is capable of independent flight or can extend his mokomoko and use it to carry himself through the air. The latter method of flight enables him to bring others along with him while flying by riding his mokomoko with him.
Immunity
Sesshomaru is immune to diseases, gases and toxins that affect humans and weaker yokai. His greatest resistance seems to be toward holy and divine powers; he was able to enter Mt. Hakurei's purification barrier, by far the strongest of its type in the series, without being purified, and has negated Naraku's attempts to absorb him. In another instance, Sesshomaru catches one of Kagomes purification arrows barehanded and to no ill-effect; any other demon would have been severely injured, if not outright purified.
Additionally, Sesshomaru is said to be "unaffected by human attacks" according to Inuyasha. Because of Sesshomaru's demonic purity, his aura emanates around his body in perfect completion, making it almost impossible to compromise. Thus, supporting Inuyasha's claim which states that human attacks will not harm Sesshomaru, and true to this, none ever have; barring one incident in Mt. Hakurei, which is excusable because of the barrier. Hence, the only damage he has sustained throughout the series has been from yokai-powered attacks. His resistance to poisons and toxins is due to his own inherent skill and power with his Dokkaso.
Speed
Sesshomaru can move faster than the eye can see, both on land and in the air. He can decapitate an entire army of samurai before they can react. Although, Sesshomaru's top speed is never disclosed, it is known that he can move incredibly fast without using much effort; appearing to be in a frictionless motion upon movement. Sesshomaru moves fast enough that he leaves afterimages. He can also instantaneously close long distances without being detected by others.
Strength
Sesshomaru possesses physical strength far beyond that of a normal demon. His strength with only one arm is equal to Inuyashas full strength; Inuyashas strength allows him to lift a 9 to 10 ton boulder using one arm with little effort, so Sesshomaru would naturally be capable of lifting double that or far more with the same amount of effort.
Senses
Due to his lineage, Sesshomaru exhibits extremely heightened senses, particularly his sense of smell. He can discern characteristics of most objects through scent, such as the undead Band of Seven through the scent of graveyard soil and pure-demon blood from half-demon blood (such as when Inuyasha's demon blood takes over). Through smell alone, Sesshomaru can follow events transpiring far away or which have already transpired; for example, he learned of everything that had happened during Inuyasha's confrontation with Goshinki by simply sniffing the area in which they fought at least several hours, if not days, after the battle.
Daiyokai Form
As the son of a daiyokai, Sesshomaru has inherited similar levels of power and thus is a daiyokai in his own right endowed with heightened senses, intelligence, strength, and a myriad of yokai powers. While he appears to be an elf-eared human bearing splendid clothing and armor most of the time, he can transform into his true InuYoukai form.
While this form grants him incredible brute strength and the ability to fly and run through the air, his large size, possible lack of agility (though he has moved incredibly quickly in his true form), and lack of ability to use his swords renders this form of limited usefulness. The toxins of Sesshomaru's poison claws are transferred into his fangs. This caused his bite to have extremely caustic effects, an ability which is also transferred to his saliva. Additionally, his saliva can be turned into a poisonous, mist-like gas.
Immortality
Being a daiyokai Sesshomaru has a longer lifespan, possibly even longer than those of normal yokai. Sesshomaru does not suffer from old age the way humans do. He appears to be 20 despite being five hundred years old. He can, however, still receive near-fatal injuries as shown when he gets stabbed in the chest by Magatsuhi.
Regeneration
During his battle with Magatsuhi, Sesshomaru's demonstrated the ability to heal the burns and gashes on his right arm, as well as several large holes stabbed right through his body. In the same battle, he was able to restore his left arm, which was cut off by Inuyasha. Although, Sesshomaru regenerates his left arm after several periods of time this is not considered to be the full extent of his regeneration ability. It's regarded that the reason Sesshomaru took a lengthy amount of time to regrow his left arm was because it was to come with Bakusaiga. Having being dependent on his father's swords it is thought that Sesshomaru had a psychological barrier preventing him from getting his Bakusaiga and being independent thus averting the restoration of his left arm much sooner.
This is supported by the fact that Inuyasha, a half-demon takes a matter of hours to restore a hole in his stomach that was made by Sesshomaru himself. Sesshomaru being a powerful daiyokai would regenerate at a much faster rate. More evidence of this is that Sesshomaru regains his left arm with his Bakusaiga after he resolves the idea that he doesn't need & won't depend on his father's swords. It is also possible that the regrowth of his arm was due to Bakusaiga manifesting, and not a feat usually possible by his normal regeneration. It is also possible that the wound, made by such a powerful sword, was unable to heal naturally until he overcame its power.
Dokkaso
Sesshomaru has claw-like fingernails, and can injure — or even kill — an entire group of thieves using his claws. He can also scratch with his claws and release a potent poison at the same time to melt his enemies. Though he normally applies it through his claw strikes, he can also spray the acid from his claws or transfer it into his punches. His poison is strong enough to melt rock or bone; a mere human will melt in an instant. If his poison is taken in internally, it will remain inside and be in effect for a long period of time — even in those with demonic power.
Mokomoko
The fur on Sesshomaru's shoulder can be extended to great lengths and used to whip, constrict and fling his opponents or carry himself through the air. However, because it is a part of his body, the mokomoko is capable of bleeding and is highly sensitive to pain, to the point that injuring it can render Sesshomaru temporarily immobilized. There is also the possibility that the blood was from his shoulder underneath, and that the pain was caused by the large wound dealt there.
Teleportation
Sesshomaru's orb of light form gives him the ability to quickly teleport away if necessary, as Sesshomaru morphed into a ball of energy to escape his father's grave.
Poison Whip
Sesshomaru can generate a thin, whip-like strand of yellow-green energy from his fingertips that can slice through almost anything. The whip also displays characteristics of poison akin to the burning effect it has on contact. It is used often in combat not only as a weapon, but at a utility tool as well. The whip can extend great distances and retreive people or objects in motion. It can also puncture armor and human flesh with intense energy similar to a projectile.
Combatant's Hands
Sesshomaru is also an accomplished unarmed fighter where he has been able to consistently outpace and overwhelm Inuyasha in hand-to-hand combat when there is the occasion that they fight without the demon swords. Sesshomaru was able to easily counter his brother's wild strikes and find an opening to quickly pummel him. He was also able to easily knock Inuyasha to the ground. Unlike Inuyasha who repeatedly throws punches everywhere, Sesshomaru on the other hand attacks when sees the perfect opportunity thus displaying greater experience and skills. During their two battles before Sesshomaru commissioned Kaijinbo to forge
Tokijin, the older demon was able to casually pressure Inuyasha wielding the Tessaiga (before he learned the Kaze no Kizu). Also during the third movie, it is shown that Sesshomaru was able fight adequately against the self-sustained body of So'unga with his bare hands and only one arm after
Tokijin was damaged by the greater demon sword, though Jaken noted that Sesshomaru was still at an overall disadvantage.
Soryuha
(Dragon Strike) is the signature move of Sesshomaru's
Tokijin and Tenseiga. A powerful burst of yoki is released and takes the form of a dragon. It draws its energy directly from Sesshomaru, and varies in strength. He can also put in the ground to break an enemy's barrier. Sesshomaru used the Dragon Strike on Moryomaru with the
Tokijin at point blank range and penetrated his armored shell, which was considered to be the strongest shell ever.
