Sesshōmaru

Sesshōmaru is an Inu yōkai as well as the half-brother of InuYasha. He and InuYasha started as a team to fight against Sasuke Uchiha and his forces and later the Akatsuki in the First Warriors War. Onwards from Second to Fourth Warriors War, he became the leader of his small faction, SHIB Team.

Sasuke's greed
Knowing Sasuke's greed for powers and immortality drove him to insanity, Sesshōmaru warned InuYasha and his allies that Sasuke seeks dominance for powers. This prompted InuYasha to form his team to fight against the invaders.

Akatsuki's assault
With the death of Sasuke and his allies, Pein and the Akatsuki decided to deal with the enemies. Pein believed InuYasha, Hinata Hyūga, Bankotsu and Sesshōmaru were jinchūriki. The Akatsuki underestimated the mighty warriors and were defeated.

SIB Team was born
Seeing their homeland was destroyed, Sesshōmaru confronted Itachi Uchiha who stated he wanted to make a truce with him since they wish for peace. Though Sesshōmaru was initially sceptical, he accepted and started their journey to Gotei 13 where they faced Byakuya Kuchiki who questioned their presence. They explained about reversing time to restore their homeland. He decided to help them on their endeavour. Now, he found himself helping them and joined the duo, thus forming the SIB Team.

Start Wars
After Itachi, Sesshōmaru and Byakuya left Gotei 13, they were on their way to InuYasha's homeland which was now ravaged by war started by Sasuke. This led to the start of the Second Warriors War.

At some point, he reunited with a chiropteran and his old childhood friend, Haji who explained he had no powers, but would somewhat lend assistance. Sesshōmaru decided to recruit Haji into his team which was renamed SHIB Team.

He again faced his old foe, Sasuke who sought his powers especially the bakusaiga. Seeing Sasuke was willing to murder Itachi for his powers; Haji, Sesshōmaru and Byakuya defended Itachi. Sakura Haruno, another member of Sasuke's faction sought to distract the SHIB Team only to be barred by Kenshin Himura who eliminated her. The SHIB Team (excluding Itachi) killed Sasuke for the second time.

Akatsuki's assault
After learning Sasuke was killed, Pein and his faction entered the battle. Sesshōmaru also faced Tobi who believed him to be a jinchūriki and destroyed his right arm, prompting him to flee. Later, he was faced by another Uchiha warrior, Madara Uchiha who was ambitious about the Eye of the Moon Plan. He also vanquished Kakuzu who placed a bounty on his head and later an evil clone of Byakuya.

Reverse Time
Enemies reversed time back to the start of the Second Warriors War to have Sasuke returned. Sesshōmaru now had to face his nemesis once more. Ichigo Kurosaki jumped in to defend Sasuke, but was brushed away easily. Madara sent his Uchiha warriors to deal with Sesshōmaru who blasted them away.

With the enemies subdued, Deidara beset Sesshōmaru, but was swept aside. Kakuzu and Sesshōmaru faced each other in a lengthy battle. However that battle was interrupted by the arrival of Naruto Uzumaki who sought to impress Sasuke by eliminating Sesshōmaru who countered the tailed beast ball with bakusaiga.

Sasuke's mad desires
Sesshōmaru also faced an evil clone of Itachi and one of Hitsugaya. Days later, Sesshōmaru faced Sasuke who murdered countless of warriors and gained newly developed powers - Kirin. With this, Sasuke murdered InuYasha, Itachi, Bankotsu, Jin, Morte Asherah, Kyrie Illunis, Shiori Momono, Sai Yamanaka and Tenten. Sesshōmaru's thoughts were on revenge especially for the deaths of his half-brother and his ally, Itachi. As a way to reduce the enemies' strength, Sesshōmaru banished Gin Ichimaru into the void.

Worse, Naraku murdered Kagura. Unable to save Kagura from death, Sesshōmaru felt annoyed. Again he faced Naruto in Round 2, but this time he retreated to a secluded place where he felt his tenseiga powered up and revived some if not all the warriors who died. Feeling relieved by this, Sesshōmaru was certain he could turn the tide. Later, he was beset by Orochimaru's spies.

Akatsuki-Espada War
Sesshōmaru and the SHIB Team faced and killed Sasuke while Pein and the Akatsuki warriors entered Hueco Mundo and faced Organisation XIII (in fillers only) and later Espada for Aizen's betrayal.

Throughout the course of the Second Warriors War, Sesshōmaru encountered Hiroku and eliminated this demonic warrior. At the end of the Second Warriors War, Aizen subtly sent some Zetsu's clones to take on the form of the Espada. He also encountered Dark San's evil counterpart.

Aizen's threat
Sesshōmaru sensed Aizen as the next threat and faced and destroyed Cell, thanks to Yuka Minase who negated his powers. Aizen made use of illusions of Deidara fighting Tia Harribel as well as a young Tobi and other messed up events to catch Sesshōmaru off balance. Unfazed by this, he continued his fight.

He also witnessed InuYasha, Byakuya and other warriors slaughter a vengeful Sakura. Thanks to Hidan's curse ritual, Sesshōmaru decided to clean up this mess by getting rid of Sakura's dead body. At the same time, Sesshōmaru witnessed Aizen prompted Itachi to use Susano'o to speed up his illness by using an illusion of Yammy Llargo. And was upset to see the death of Itachi and faced an illusion of Barragan and later Szayelaporro Granz. With the death of one of Tobi's clone, Sesshōmaru ordered Zetsu to dispose of it.

At the end of the Third Warriors War, Sesshōmaru finds an old enemy - Yue who now works with Aizen. At the same time, he senses a now enhanced Kabuto Yakushi who has a rendezvous with Tobi.

Tobi's plan
After learning Tobi initiated the Fourth Warriors War, Sesshōmaru urged InuYasha and allied warriors about this new threat. Sesshōmaru continually faced Yue for killing Yukiko Hirohara and stole the voidstone to further Tobi's schemes. However, this plan failed as he reclaimed the voidstone, powered it up and allowed Yukiko to revive herself anytime.

He was in danger not just because of Tobi, Kabuto, Aizen and Yue, but also because Sasuke survived Sesshōmaru's assault. He also countered Sasuke's Kirin from killing his allies as this happened before. On the Crashing Waves Coast, Sesshōmaru faced Tobi's Demonic Statue of the Outer Path by countering its attacks, killing the allied warriors and enemies alike. With the undead Hashirama Senju attacking the allied warriors in the Land of Hot Water, Sesshōmaru was trapped until InuYasha's timely arrival.

By nightfall, zombies were sent by Kabuto to attack the people of any town to which Sesshōmaru prevented.

Tenten's gone missing
On the next day, Sesshōmaru saw Aizen who has taken a demonic transformation. Thanks to InuYasha's fight and Yuka who nullified Aizen's powers, Sesshōmaru vanquished the leading figure of Espada. He also offered assistance in Deltora against the invaders.
