Originally a Genin level ninja that graduated with , Shikamaru is a lazy, easy-going genius who was promoted to Chunin level after the Chunin Exam Arc. He is from a family of shadow manipulators and deer herders. His main technique is Kagemane no Jutsu (Shadow Imitation Technique). Later in the series, his father teaches him his second jutsu, Kage Kubi Shibari no Jutsu (Shadow Neck Bind Technique ), an extension of his first technique.
Shikamaru is the sort of unenthusiastic person who would rather take a nap than get excited over something and likes the thinking games that older men are usually into, such as Shogi and Go. Shikamaru even decided to sleep during the attack of Konoha by the Sand and Sound, as he thought it would be too troublesome to get up and fight, after he had dispelled a sleeping genjutsu cast by the enemies. This was found out after Sakura was about to cancel the genjutsu and found out he was in fact aware of his surroundings, much to her annoyance.When thrust into action-laden situations, uncomfortable situations, or indeed, any situation at all that would require him to exert himself, he tends to remark how "Mendokuse" (from "Mendokusai,meaning "Bothersome," or "Tiresome", or "Troublesome" - although in context it carries a sort of "Aw man..." and "Screw it..." meaning as well; translated as "a drag" in the English dubbed version) the whole thing is. He is fully aware of this side of his personality and even dubs himself "the number one at running away" or the number one coward.
However, when duty calls, Shikamaru has a strong moral compass and sense of commitment to his comrades. Even though by his own testimony he lacks bravery, he will sacrifice himself and face almost certain death for the sake of his friends without a second thought, such as when he stayed in back to confront the Sound Ninjas, giving Naruto enough time to catch up with Sasuke. Since he has been promoted to Chunin, his responsibility for the lives of his friends has weighed very heavily on him on occasion.
Shikamaru is a brilliant strategist, and though his sensei, Sarutobi Asuma, often plays Go and Shogi against Shikamaru, he has never actually managed to beat him. Asuma got suspicious upon realising that Shikamaru was so good at board games despite his abysmal grades, which were almost as low as Naruto's. As a result, Asuma administered an IQ test disguised as a game to Shikamaru, which revealed that Shikamaru was a genius with an intelligence of over 200. Shikamaru had felt that even moving his pencil in class was a bother and always slept through tests, resulting in his low grades. Shikamaru has a habit of putting his fingers together to create a circle and closing his eyes so he can concentrate and come up with a strategy. Once he does, which often takes only a few minutes, he is often already thinking way ahead of his opponent.
Shikamaru has a longstanding friendship with , in whom he has complete trust. Before they were promoted to Chunin rank, Shikamaru, Chouji and Yamanaka Ino were on the same Genin team under Asuma. Their fathers were on the same team as well. Their teamwork is unparalleled.
