Shikaku Nara

is the father of Shikamaru Nara and the husband of Yoshino Nara. He is the Jonin Commander of Konoha. He greatly resembles his son, with the exception of his more matured appearance and the few scars on his face. He was also a member of an Ino-Shika-Cho trio.

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.

Since Shikamaru became a Chunin, Shikaku has taken a great interest in his training, teaching him the clan's more secret techniques and having great confidence in Shikamaru's abilities. He also spends his time tending to the clan's deer.

Part I
Shikaku debuted in the anime during the Chunin Exams, attending a festival with his former teammates and giving Inoichi Yamanaka a hard time for having had a daughter. His manga debut occured during the invasion of Konoha, where he fought alongside his former teammates to repel the invading forces.

Later, when Shikamaru failed during the course of a mission and some of his teammates 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, he was summoned by the ANBU captain to meet with the seniors of Konoha. Shikaku nominated Kakashi to become the next Hokage, which was met with the council's agreement. However, Danzo spoke against the ideologies related to the Third Hokage, and went into his fanaticism of power over trust. Shikaku tried to persuade the council not to take Danzo's ideals into account, but was overruled by Danzo's appointment as the Sixth Hokage.

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 used the Shadow Neck Bind Technique against three opponents at the same time. He is also shown to be very intelligent, regularly beating Shikamaru at shogi.
