Two and a half years later, at the beginning of Part II, Naruto ran into Shikamaru and Temari soon after returning to the village. Naruto misunderstood that Shikamaru and Temari are a couple, although both denied this, explaining that they were working on planning for the next Chūnin Exam. This later prevented him from helping with Naruto's first attempt to look for Sasuke, but he was able to help during Naruto's brief scuffle with Sai.
Twelve Guardian Ninja Arc Edit
In the anime, when Konoha was invaded by Furido and his team, Tsunade put Shikamaru in charge of Konoha's defense. He grew frustrated that his friends were fighting on the ground while he was on the back lines. Shikamaru stated that a strategist must lead his troops from the front line, and not be afraid to take risks. After getting Ino, Shikamaru led the counter-attack against the undead, ordering an attack plan which drove the enemy back. Later, Shikamaru used his Shadow Imitation Technique to bind Sora.
Hidan and Kakuzu Arc Edit
Shikamaru was revealed to be a member of the Nijū Shōtai, where he was teamed up with Asuma, Izumo Kamizuki, and Kotetsu Hagane in an effort to track down and eliminate any and all members of Akatsuki. Eventually, the team found one such member: Hidan, and, as Shikamaru restrained Hidan with his Shadow Imitation Technique, the rest of the team were able to co-ordinate a finishing attack on Hidan. When it was revealed that had done little to stop Hidan, Hidan's partner, Kakuzu, appeared, forcing Shikamaru to release Hidan.
As Asuma battled Hidan, Hidan began a ritual that caused all damage done to himself to be inflicted on Asuma as well. Because of Hidan's apparent immortality, Hidan was able to use this to his advantage, giving himself injuries to easily harm Asuma while not being affected by the debilitating blows himself. To help Asuma, Shikamaru captured Hidan with his shadow once again, and adopted his meditative analysis of all of Hidan's actions and words up to that point. He quickly realized that the "link", created when Hidan consumed Asuma's blood, could only be maintained by Hidan remaining within the blood seal that he had earlier drawn on the ground, so Shikamaru pulled him out of it. With damage done to Hidan no longer harming Asuma, Shikamaru tied Hidan down with his Shadow Sewing Technique, allowing Asuma to decapitate the Akatsuki member.
However, even this was not sufficient enough to kill Hidan. After Kakuzu reattached his partner's head, he joined the fight and pinned down Izumo and Kotetsu, while Hidan managed to bind Asuma to his curse jutsu again by stepping back into the blood seal. Shikamaru rushed to the aid of his sensei just as Hidan impaled himself with his pike, delivering the final blow to Asuma. Chōji and Ino arrived as back-up, and Hidan and Kakuzu were driven off. Ino tried to heal Asuma, but there was nothing she could do, and the students were only able to listen to Asuma's final words. To Shikamaru, Asuma said that he had great potential, perhaps enough to one day become Hokage. After Asuma died, Shikamaru began smoking his last cigarette, blaming its smoke for his tears.
Shikamaru did not attend Asuma's funeral, instead coming up with a plan to defeat the Akatsuki duo. This was drawn out considerably in the anime, where his father made an attempt to comfort him with a game of Shogi, though Shikamaru could only blame himself and was too invested in revenge. When he finished his preparations, he set out with Ino and Chōji. They were stopped by Tsunade, who insisted that they stick to the usual four-man team. Kakashi appeared, and volunteered to help, so Shikamaru quickly modified the plan to accommodate for his presence.
Upon finding Hidan and Kakuzu, Shikamaru used Asuma's trench knives, swelling with his shadow, to restrain the Akatsuki members by pinning their shadows. With the two unable to fight back, Shikamaru prepared to trap the two with his Shadow Imitation Technique to allow him more of an advantage, though Kakuzu was able to escape before Shikamaru could ensnare him. With Hidan under his control, Shikamaru used Hidan to attack Kakuzu, forcing him into a corner where Kakashi attacked him with his Lightning Blade. This destroyed only one of Kakuzu's four extra hearts, and, surprised by this turn of events, Kakashi and Team 10 regrouped. After being left on the defensive for a while, Shikamaru concluded that they must separate Hidan and Kakuzu if they were to win. To this end, Shikamaru again caught Hidan with his shadow, and led him away.
Once far enough, he covered the area in exploding tags to corner the immortal. The time limit on his Shadow Imitation then ran out, so Hidan was able to attack him, get some blood, and initiate his ritual. Hidan quickly stabbed himself in the heart, causing an apparently dead Shikamaru to keel over. Shikamaru was, however, alive and well; the blood had been Kakuzu's, Kakashi having taken a sample when he earlier used Lightning Cutter. In effect, Hidan stabbed Kakuzu in the heart. With Hidan oblivious, Shikamaru tried to decapitate him with a short sword. The cut was too shallow to sever the immortal's head, prompting Shikamaru to capture him in a Shadow Imitation instead - albeit a much weaker one at this point, with his chakra running low
As Hidan tried to attack Shikamaru, Shikamaru used his Shadow Endgame Technique to cover Hidan with the exploding tags in the area. With Hidan tied in place, Shikamaru activated a mark he had prepared before the battle, causing the ground beneath Hidan to collapse into a pit. Shikamaru explained that the surrounding forest was the property of the Nara clan; only they were allowed to enter or leave the forest, thus ensuring that Hidan's remains would never be found. After lighting a cigarette, in anime, Asuma's lighter, Shikamaru flicked it at Hidan, setting off all of the exploding tags at once.[8] Hidan's remains fell into the pit and, as he swore vengeance against Shikamaru, Shikamaru forced a cave-in. The battle won, he regrouped with his team, Kakuzu having also been defeated, and returned home. When he got back, Shikamaru stated to Kurenai that it is now his ambition to protect and train the next generation of ninja.
Invasion of Pain Arc
Shikamaru was left in charge of deciphering Jiraiya's dying message about Pain. When informed by Shiho that the Konoha Cryptanalysis Squad couldn't break the code without some sort of key, Shikamaru approached Naruto for help. Using his own experiences with Asuma's death, he helped him to get over Jiraiya's death, pointing out that they would someday both have students, and would go to great lengths to protect them, just like Asuma and Jiraiya. Revitalized, Naruto helped to decipher the message as "The real one is not among them." Shikamaru was then left with to try and figure out what this meant, but was interrupted by Pain's invasion of Konoha.
In the anime, Shikamaru immediately went to check on Kurenai's condition and ended up protecting her from a Giant Centipede. After killing the summon, with his shadow and explosive tags, he helped Kurenai to the underground passage to evacuate.[9] After the village's destruction, Shikamaru and his father were shown to have survived. He received a broken leg when he used his body to shield Shiho from harm.[10] They regrouped with Ino and her father, and pooled their knowledge of Pain to try and figure out his secret. They discovered that Pain had a main body that must be nearby, so Inoichi and Shikaku, went looking for it. Because his leg made it difficult to move, Shikamaru stayed behind, later joining in on the celebration of Naruto's defeat of Pain.
Five Kage Summit Arc
Shikamaru went to find Team 7 after his team, Team 8, and Team Guy, have decided that Sasuke must be handled by Konoha to avoid a war with Kumogakure. He asked for Sakura's permission, but told her they'll do it either way and if Ino, Naruto, or her were hurt or killed they would want revenge continuing a cycle of violence that will never be broken. Neji explained not to make the same mistake he did as a chūnin before. He asked to speak to Naruto, but is told he's in the Land of Iron. Sakura told him that she will be the one to speak with Naruto. Along with the rest of the Konoha 11, Shikamaru is prepared to kill Sasuke. Shikamaru is seen with the rest of the Konoha 11 and is skeptical about Naruto's decision on dealing with Sasuke.
Confining the Jinchūriki Arc
Shikamaru is present with his father during the meeting the village held as they prepared for war.
Shinobi World War Arc He is later assigned to the Fourth Division alongside Chōji and Temari under Gaara. Because Gaara is also the Commander and Chief of the whole army, he named Shikamaru as Proxy Leader. Because of this, Temari encourages him to look and act more like a leader, causing him to remark how troublesome things have become.
you should really add some pics to it....
