Shikaku Nara

is the father of Shikamaru Nara and the husband of Yoshino Nara. He is the Jōnin Commander of Konoha and was also a member of an Ino-Shika-Chō trio alongside Inoichi Yamanaka and Chōza Akimichi.

Personality
When he was first seen, he was portrayed as a bit of an alcoholic, and, at times, uses some of Shikamaru's catchphrases ("What a drag" in English and "How troublesome" in Japanese). Like his son, he thinks that women should be tender and sweet, but, as his son says, his wife has him "whipped". Also like his son, he is a very intelligent but lazy person, yet he is also quite caring, and is ready to jump into action when needed. Unlike his son, his resolve is much stronger, as even during the most depressing or dangerous of situations, he has been shown to maintain great determination and understanding, as shown from how he has repeatedly helped Shikamaru regain his sense of worth. In battle, Shikaku appears merciless. He had no qualms about choking the Suna shinobi to death, even when one of them was clearly cowering.

It was also revealed that he was amongst the few parents who did not order his son to stay away from Naruto Uzumaki. He instead encouraged Shikamaru to do what he thought was best.

Since Shikamaru became a Chūnin, Shikaku has taken a greater interest in his son's training and has started teaching him the clan's more secret techniques. He also spends a great deal of his time tending to the clan's deer.

Appearance
Shikaku has two scars on the right side of his face which are probably his most noticeable feature. Like his son, he has dark hair tied up into a spiky ponytail, dark eyes as well as a goatee. His ears are also pierced. In Part I, Shikaku wore a meshed shirt underneath his flak jacket, a deer skin coat over that and hand guards. In Part II however, he has been seen in the standard Konoha shinobi outfit. Earlier in the anime, Shikaku also has a scar on the left side of his face, however, this scar had been removed since subsequent episodes.

Abilities
Like other Nara, Shikaku uses the manipulation of shadows in various ways. Although he has only been seen in combat once, as the head of his respective clan it is assumed that he has mastery of his clan's techniques. During the invasion of Konoha, Shikaku was able to use the Shadow Neck Bind Technique against three opponents at the same time very easily. He is also shown to be very intelligent, regularly beating Shikamaru at shogi.

Chūnin Exam Arc
Shikaku debuted in the anime during the Chūnin Exams, attending a festival with his former team-mates and giving Inoichi Yamanaka a hard time for having had a daughter. When Shikamaru came to pick him up, he instead asked his son why he was not enjoying the festivals.

Invasion of Konoha
During the Invasion of Konoha, he fought alongside his former team-mates to repel the invading forces and used the Shadow Neck Bind Technique.

Sasuke Retrieval arc
Later, when Shikamaru failed during the course of the mission to save Sasuke, and some of his team-mates suffered severe injuries, Shikaku spoke with him. He encouraged his son to keep his responsibility as team captain, as it might be that a team on a mission without him could have several casualties, but, if he was there, that team might end up with no casualties.

Hidan and Kakuzu Arc
Shikaku appeared following Asuma Sarutobi's funeral, comforting Shikamaru about Asuma's death and offering to play shogi with him. After Shikamaru avenged Asuma and they played shogi again, he discussed the concept of the "king" with Shikamaru before defeating him.

Invasion of Pain Arc
Shikaku was later shown to have survived Pain's destruction of Konoha, along with Shikamaru and Shiho. Apparently having some knowledge of senjutsu, he told his son not to interfere with Naruto's fight with Pain, and they instead regrouped with nearby villagers. He and Inoichi went searching for Pain's real body soon afterwards, only to run into Naruto, who had defeated Pain. When Naruto told them not to follow him to Pain's base, as he wished to speak with Pain alone, Inoichi argued that talking wouldn't solve anything. However, Shikaku, remembering Shikamaru's words about Naruto, convinced Inoichi to comply. When Pain then revived all those who he had killed, Shikaku realized he made the right choice in trusting Naruto.

Five Kage Summit Arc
After the invasion, Shikaku is one of five Konoha villagers to be summoned before the Fire Daimyō to discuss the village's response and reconstruction. With Tsunade in a coma, Danzō Shimura also suggests selecting a new Hokage. Fearing that Danzō may be appointed to the position, Shikaku nominates Kakashi to become the next Hokage. Much of the council agrees, but Danzō is able to undermine Kakashi's credentials. Shikaku tries to persuade the council not to take Danzō's ideals into account, but despite that, the daimyō decides to appoint Danzō the Sixth Hokage.

Confining the Jinchūriki Arc
When Danzō is killed, Shikaku is once again called before the daimyō, this time to appoint Kakashi to the position. The meeting is interrupted when news arrives that Tsunade has woken up, bringing an end to the proceedings. Shikaku is also present at the village's war meeting with his son, stating he believes him to be too young for it, as they prepare for war. Shikaku later escorted Tsunade to a meeting of the leaders of the Allied Shinobi Forces and agreed with them on how they would protect both Naruto and Killer Bee.

Shinobi World War Arc
He remains behind at the headquarters alongside Tsunade, acting in the capacity of battle strategy tactician. When the Raikage learns that the Gold and Silver Brothers were resurrected and states that he was going to enter the fray, Shikaku tells him that he cannot do that as he needs to remain behind to act in his capacity as Supreme Leader. He then proposes a new battle tactic after being informed of the number of powerful enemies that Darui's division was facing. The Fourth Raikage then praised Tsunade for the caliber of ninja in Konoha. Shikaku then tells Inoichi to inform the rest of the squads about the movement and then says he thinks it is time Ino-Shika-Chō made an appearance, but is interrupted by Ōnoki who says he has to deal with the Second Tsuchikage himself. Shikaku expressed great shock after learning that the Mū also had a kekkei tōta like the Ōnoki.

When the headquarters receive information the First Division's situation and Kinkaku's transformation, the Raikage prepares to send them the Kohaku no Jōhei. When Tsunade questions how they'll make Kinkaku activate its ability despite knowing about it, Shikaku relays a strategy to Darui, Ino, Chōji and Shikamaru, through Inoichi. Shikaku utilizing Inoichi Yamanaka's telepathic powers contacted Ino, Choji and Shikamaru, instructing them to utilize the Formation Ino-Shika-Chō to get Kinkaku's attention when Darui summons him to the Kohaku no Jōhei. The plan was effectively implemented, sealing away Kinkaku.
