The Bug Master
Shino is a fair-skinned ninja and the tallest member of his graduating class. He has dark bushy brown hair and dark, narrow eyes, the latter of which has only been shown in the anime. Shino is regularly seen sporting the same style as the rest of his clan, consisting of dark sunglasses and a sea-green jacket with a high, upturned collar.
During Part II, his appearance became even more mysterious, with his jacket hanging down to his knees and the addition of a hood that obstructs his face even more and a satchel on his back. This current appearance makes it harder for people like Naruto to recognise him right away. During the Fourth Shinobi World War, he wears a flak jacket under his jacket.
Shino Aburame is a calm, collected, and solitary person, who is quite mysterious. He is portrayed as being somewhere between merely stoic and matter-of-fact, rarely ever smiling or showing emotion at all; rather than thank his team-mates for congratulating him on his victory in the preliminaries, he told them that he expected them to do the same. He also has a tendency of holding grudges and being rather intimidating, such as seen when Naruto failed to recognise him at the start of Part II (which is fair as the only visible part of his face was his sunglasses), but easily recognised Kiba and Hinata. He still holds that grudge to this day.
Shino speaks in a curious fashion, as noted by both Naruto and Kiba. He speaks in a manner most simply described as "nitpicking" and uses the word 'because' (なぜなら, nazenara) a great deal.
In the first part of the Chūnin Exams, Shino used his insects to read the answers on other people's tests. During the second part, his knowledge of insects allowed his team to take another team's scroll with little effort; when leeches attacked another team (from the Amegakure in the anime, from the Konohagakure in the manga), they stumbled into a net trap.
During the preliminary matches of the Chūnin Exams, Shino was matched against Zaku Abumi. Because one of Zaku's arms was in a sling, Shino advised him to forfeit the match. Zaku refused, and instead attacked Shino with his one good arm. In attacking Shino, Shino was given an opportunity to box in Zaku with bugs, forcing Zaku to choose between attacking him or attacking the bugs, leaving the other to attack Zaku from behind. Zaku chose to attack both, and pulled his other arm out of its sling. As Zaku prepared to blast the two opposing forces, his arms detonated, making them unusable and putting him in immense pain (in the manga, his right arm was even blown off of his body). As Zaku writhed, Shino revealed that the tubes in Zaku's arms had been filled with his bugs, causing the pressure of Zaku's attack to go outward when it couldn't escape.
Shino was scheduled to fight against Kankurō in the final rounds, but Kankurō forfeited before their match began to avoid revealing the secrets of his puppet Crow. The invasion of Konoha started soon afterwards.
When Kankurō fled the village, Shino followed him, wanting the fight he had been denied. Shino caught up with Kankurō about to fight with Sasuke, allowing Sasuke to continue on ahead while they had their match. Kankurō attacked Shino from a distance with his puppet, and Shino used his bugs to make otherwise impossible evasions. A poisonous gas attack, however, caught Shino by surprise. Although he was able to avoid the worst of it, Shino breathed in some of the gas. As the battle progressed, Shino used his bugs to eat away at the chakra strings that Kankurō used to control his puppet, forcing Kankurō to frequently relinquish and reacquire control of his only weapon. All the while, Shino directed his bugs to the scent of a female bug planted upon Kankurō's head, and upon reaching Kankurō, they consumed his chakra. As Kankurō collapsed due to the sapping of his strength, Shino collapsed too, the poisonous gas taking effect. After regaining consciousness, Shino found his father, Shibi Aburame, standing over him, using his own bugs to draw out the poison in Shino's body.
Shino had a supporting role in the Kurama Clan Arc, as while Kiba complained about Kurenai leaving the team, Shino suggested that it was her decision to do so. He also correctly guessed that Kurenai was lying when she said that she sealed Yakumo's abilities out of jealousy, noting that while her hands were trembling when talking about her past, they stopped when she gave her reason. His bugs proved useful against the genjutsu used by the Kurama clan members and Yakumo, as according to him, insects' simpler nervous systems are harder to manipulate. Shino sent his bugs into the room where Yakumo was holding Kurenai in order to save his sensei, only to see them come back. He reunited with Kurenai after the Ido's defeat.
In the anime, Team 8, under Kakashi's leadership, was sent to investigate one of Orochimaru's hideouts. It was destroyed upon their arrival, and they searched the surrounding area in search for clues. When they found a number of people encased in crystal, a fate shared by some of Shino's bugs, they sent a sample to Konoha for analysis. While waiting, Shino discovered that some of his bugs were resistant to the crystal, so he bred them to increase their numbers. Doing so required that he separated from the team.
Later, he reunited with his team in time to help them avoid a trap. Though the enemies retreated, Shino discovered that his bugs had yet to develop a complete immunity to the crystal. Soon afterwards, they were trapped by Guren, the source of the crystal, and Hinata was captured and encased in crystal. When back-up arrived and saved her, she revealed that she survived the crystallising process by encasing herself in chakra. Shino's bugs had done the same, which was why he had been unable to selectively breed an immunity. The team pursued Guren, but were distracted by the appearance of the Three-Tails.
Shino was assigned to help the members of the team that were trying to seal the beast. When Guren attacked in an effort to stop them, Shino, knowing his bugs were the best chance at defeating her, stayed back to prepare his insects. Once giving them enough chakra to coat themselves in, the bugs were able to completely overpower Guren's crystal techniques. Shino continued to protect the sealing team after defeating Nurari.
During this arc Shino is acquainted with Sai, the replacement on Team 7 for Sasuke. Naruto introduces them but doesn't have much to say about Shino, therefore hurting Shino's feelings. Because Sai knew more about him than did his friend of 3 years.
Shino was placed in the Fifth Division. He stated that his team should avoid drawing attention to themselves, to which Ino assured him that it won't be difficult. After Kitsuchi blew the White Zetsu Army out of the ground, Shino used his Secret Technique: Insect Sphere to attack them. Shino states that not only are the White Zetsu Army strong, but they're "durable as well and says that if this keeps up, it'll end up being a war of attrition." After the first day of fighting, Shino is seen alive along with Kiba, Akamaru, Hinata, and Neji. Later, while Neji rests and Hinata takes on Neji's duties as a lookout, Shino tells her not to overexert herself as well as he had his bugs scattered all over the area.
In the anime, when the White Zetsu Army had infiltrated the Allied Shinobi Forces and began assassinating each member one by one, Team 8 were sent to a cave that was a hole to the allies' defenses. Team 8 encountered the White Zetsu clones but an explosion occurred and everyone had scattered. Afterwards Shino found that one member of the accompanying Sealing Team was stabbed with a kunai after the explosion had occurred. Knowing that the White Zetsu could absorb the chakra of their enemies to impersonate them, Shino (who did not have any physical contact during the fight) was the only one who could not be impersonated. Team 8 distrusted each other as the imposter but Shino figured out a way to discern the imposter with a game of rock-paper-scissors. Shino and Kiba (who had figured out the signals during that game) rooted out the White Zetsu clone impersonating Hinata and defeat it. They later found Hinata lying unconscious. Once outside the cave, Shino discerned that the Zetsu clones had already collected personal data on each Allied Shinobi member courtesy of Yamato, meaning that the clones already knew of Hinata's love for Naruto.
After being informed by Inoichi from HQ that Naruto and B were fighting the "masked Madara", Shino and the rest of the Konoha 11 rush to his aid. As he runs, he states that he would flawlessly support Naruto with his power and that this time, there was no because. Upon arriving at the battlefield, Shino and a few other Aburama immediately use the Insect Jamming Technique in tandem with the Kiri-nins' Hiding in Mist Technique to obscure their position on the battlefield. He, and the other members of the Allied Shinobi Forces later stood to face their opposition.
