Ibiki Morino

is a Konoha Tokubetsu Jōnin and was the examiner for the first part of the Chūnin Exams. He is also the head of Konoha's ANBU Torture and Interrogation Force.

Background
Sometime before the start of the series Ibiki hosted a portion of a chūnin exam in which he failed his younger brother, Idate; later saying he wasn't fit to be a shinobi. Later after his brother left the village Ibiki uncovered a plan to steal a secret jutsu scroll and the Sword of the Thunder God by Aoi, Idate's sensei, and his little brother to which he and two fellow ANBU members gave chase after the two. However, Aoi quickly brought in Amegakure allies to capture Ibiki and eliminate the two ANBU members with him. Aoi then tortured Ibiki to read the scroll, in the process accidentally setting the building on fire after Ibiki managed to free both himself and his little brother. However, despite Ibiki's fierce efforts, the flames soon separated the two siblings. Believing his brother to be dead, Ibiki was forced to return to the village alone.

Appearance
Ibiki has a large, imposing figure, which he complements with a rugged head and face covered with old wounds and scars. Ibiki's head is always covered to hide a collection of burn marks, punctures from where screws were used, and long slash marks. The scars are indicative of the physical torture he has endured in the past, and illustrates his capacity to endure pain without giving up the desired information to the enemy.

Personality
Ibiki is the commanding officer of the, and is the designer of the Chūnin Exam's first test. He has been described as a sadist by some.

Abilities
Ibiki is a master of interrogation, and has the ability to subject people to great suffering without ever using physical torture. His interrogation skills rely solely on his ability to torture the mind. He has complete knowledge of human psychology; by attacking a person's mind, he can gain control over their spirit.

He has fought only once in the anime, against the Animal Path of Pain. He is shown to be very skilled at the Summoning Technique, but his summons seem to revolve more around trapping and torturing devices rather than creatures. He both used the Summoning: Iron Maiden to trap Giant Rhino and the Summoning: Torture Chamber to also trap and interrogate the Animal Path.

Chūnin Exam arc
Ibiki is the first examiner of the Chūnin Exams, testing his students during the written exam with questions too hard for any Genin to answer. Therefore Ibiki secretly put two Chūnin into the crowd to answer the questions and to make other Genin try to cheat off of their exams. Although the point of the test was to test the participants' information-gathering skills, Naruto Uzumaki did not realize this. Nevertheless, Naruto was able to pass the exam without answering a single question, a fact Ibiki took great interest in.

Invasion of Konoha arc
Ibiki later guarded Konoha's borders during the invasion of the village by Sunagakure and Otogakure. He recounted to his colleagues the dark past of Orochimaru, and greeted Jiraiya when he came to their aid.

Land of Tea arc
He appeared again in the Land of Tea in anime, meeting with his younger brother Idate again for the first time in years.

Hidan and Kakuzu arc
He interrogated Kakuzu's bounty-hunting contact in order to gain information on Akatsuki.

Invasion of Pain arc
Jiraiya later sent him a prisoner from Amegakure. When his interrogation methods proved ineffective, he called on Inoichi Yamanaka's assistance, and ultimately distracted the Akatsuki leader, Pain, in order to give Inoichi time to complete the job. Later then in the anime, the Animal Path confronted the group and was after Shizune. Ibiki and three unnamed ANBU took care of the Animal Path while the rest of the group went to the Cipher Division. He used the Summoning: Iron Maiden to battle the Giant Rhino and the Summoning: Torture Chamber to question the Animal Path. He felt the Animal Path's pain but the Animal Path still didn't budge. Ibiki then concluded that the Animal Path doesn't know pain. The Animal Path then told Ibiki that he didn't know true pain and broke out of the chains and performed a Summoning Technique on Ibiki's body. After the torture chamber was gone, a Giant Drill-Beaked Bird then came out from the part of Ibiki's body where the Animal Path performed the Summoning Technique.

Fourth Shinobi World War
When Karin was taken by Kakashi Hatake to the village, Ibiki and his ANBU colleagues interrogate her about everything she knew about Sasuke Uchiha and Kabuto Yakushi.
