Danzō Shimura was an elder of Konohagakure and leader of the disbanded ANBU faction: "Root". He was later appointed as the official Sixth Hokage Candidate (Rokudaime Hokage Kōho) after Pain's invasion.

Danzō was once friends with Hiruzen Sarutobi as early as his childhood, and despite his best efforts, Danzō always felt inferior to Hiruzen. During the First Shinobi World War, Danzō, along with his team-mates, Kagami Uchiha and Torifu Akimichi, as well as Hiruzen and his team-mates, Koharu Utatane and Homura Mitokado, formed a squad led by the Second Hokage. At some point, the team was pursued by enemy Kumogakure ninja. They realised that one of them would need to distract their pursuers, and that whoever did so would die. Hoping to die for his companions, just as his father and grandfather had, Danzō tried to volunteer but was paralysed with fear at the prospect of his death. Hiruzen volunteered before he could compose himself. Angry that Hiruzen had once again beaten him, Danzō began to protest, but Tobirama decided to be the decoy instead. Before leaving, Tobirama appointed Hiruzen as the Third Hokage.

With Hiruzen having beaten him to the title of Hokage, Danzō began planning to someday attain the title himself. To that end, he created the ANBU subsidiary named Root.[2] Although the group was later officially disbanded, it remained secretly active. During the Third Shinobi World War, Danzō agreed to help Hanzō of Amegakure in order to receive help in claiming the title of Hokage. He sent some of his forces to deal with the Ame Orphans but they were all wiped out by Nagato. He would later betray Hanzō at some point in history.[3]

After the Nine-Tailed Demon Fox attacked Konoha, Danzō was one of the elders to suspect that the Uchiha clan was involved in this incident and supported relocating the clan to a secluded area of the village where they could easily be monitored. When word reached Konoha's leadership of a planned coup d’état by the Uchiha clan, Danzō took advantage of Itachi Uchiha's pacifist tendencies and convinced him to provide him and the other elders with information of the clan's actions. When Hiruzen's attempts to end the coup diplomatically failed, Itachi was ordered to wipe out the Uchiha clan. However, Itachi refused to kill his younger brother, Sasuke Uchiha, and threatened to share everything he knew about Konoha with rival countries if Danzō ever harmed Sasuke. He met with Madara Uchiha around this time for as yet unknown reasons.[4] Before Shisui Uchiha was killed, Danzō took and implanted his right Sharingan[5] and later his arm into his own body. He also worked with Orochimaru to implant Hashirama Senju's DNA into his right arm, modifying his physical energy. Madara speculates this was done to allow Danzō to use his eleven Sharingan at once, with the additional effect of allowing Danzō to use Wood Release ninjutsu and ultimately the forbidden dōjutsu: Izanagi.

The Fourth Raikage insinuated that the Danzō used Akatsuki at the time of the invasion of Konoha, more exactly a secret alliance with Orochimaru who at the time was no longer a member of the organisation, to dispose of the Third Hokage and the Fourth Kazekage.

When younger, Danzō was a hot-headed and eager ninja with a strong desire to prove himself. As an adult, Danzō was a calm and collected individual who, like the Root members that served under him, did not allow his emotions to surface. Danzō's beliefs differed from those of the Hokage as he felt that the interests of the village should be placed above all else, even ethics and morals. Danzō seemed to hate the previous Hokage's beliefs stating those beliefs have destroyed the village after the Invasion of Pain, despite that he seemed to still care for his friendship with Hiruzen, asking what he was to Hiruzen in his final moments. An extremist, Danzō preferred to directly eliminate threats through assassination and execution rather than diplomacy and negotiation. Danzō possessed a fanatical adherence to the ideals of a shinobi, believing they must sacrifice absolutely everything for the village. Danzō himself feared death, believing he must live in order to help the world accustom itself to his ideas for peace.

Despite his reputation as a "war hawk", Danzō ultimately sought peace for the ninja world, one he would achieve by uniting all shinobi forces under Konoha's control. As such, he sought the title of Hokage, waiting patiently for decades before an opportunity arose. To that end, he worked in the shadows to ensure that this future came to fruition. He used Root to eliminate potential threats to Konohagakure with or without the consent of the Hokage and to further him along the path to achieving that rank, as he believed he was best prepared for the "necessary" transition. Because of the nature of his actions, Danzō could not allow the details of what he had done to become public knowledge, and thus he branded members of Root with cursed seals to prevent them from revealing his secrets.

In spite of his amoral methods, Danzō did have some sense of nobility and honour within him. He, after a long internal struggle, volunteered to buy time for his team-mates when they were younger, though Hiruzen Sarutobi beat him to it. He reprimanded Sasuke for his hatred and violence against Konoha, saying that it had wasted both the sacrifice of the Uchiha and Itachi's own personal sacrifices. Like Hiruzen, he used the final moments of his life to help Konoha by trying to take Sasuke and Madara Uchiha with him.

His fellow elders, Homura Mitokado and Koharu Utatane, held Danzō in high regard, and often took his advice when dealing with the politics of the village. It is unknown how much they know about his actions.

Danzō appeared as an old frail man, who would normally walk with a cane. He had black shaggy hair, and his right eye is kept bandaged concealing a Sharingan underneath. Danzō has had an x-shaped scar on his chin ever since his youth. He wore a white shirt, with a brown robe over top of it covering from his feet, to just over his right shoulder. The robe conceals his right arm which was bandaged, and covered with three big golden braces. The bandages hid ten more Sharingan embedded in his arm and a strange facial pattern on his right shoulder where he integrated the First Hokage's cells into his own body.

In his youth Danzō had the same shaggy hairstyle, except it was much longer, reaching eye level. He also wore a samurai armour similar to the ones worn by the founders of Konoha, as well as a forehead protector. At that time, he still has both of his normal eyes. He hid the right eye with bandages by the time he united with Hanzō in their attack against Akatsuki led by Yahiko, and wore a flak jacket.

Danzō was a very powerful ninja, who even up until his death, was considered to be one of Konoha's best by the elders Homura and Koharu.[6] Danzō was able to easily kill several would-be assassins and was able to fight on the same level as Sasuke Uchiha, despite his old age, holding back so he could fight Madara and being unable to use Shisui's Mangekyō Sharingan. He also was talented in both using and dispelling genjutsu, even Sasuke's inept Tsukuyomi.

Danzō possessed the Sharingan of Shisui Uchiha, which he normally kept concealed under bandages. Danzō has stated that Orochimaru's data could help with his eye; presumably wanting to increase his ability to use it. He was also very skilled at using Shisui's Sharingan, detecting multiple assassins in the forest and massacring them all. He also had access to the Kotoamatsukami technique, the ability of Shisui's Mangekyō Sharingan, through which he could manipulate other people's thoughts without them being aware of it. This technique seemingly did not require direct eye contact, as demonstrated when Danzō manipulated Mifune's thoughts without exposing his Sharingan. Danzō stated that he could only use this technique once a day.

Danzō's most fearsome trait resided in his right arm, which held a total of ten Sharingan embedded onto it. The arm itself originally belonged to Shisui as well; this most likely reduces the draining effect of the Sharingans. He normally kept the arm hidden under bandages and a gauntlet-like seal, presumably to conserve chakra. Although he could not see through the eyes or use their passive abilities, he was able to access the Izanagi technique, a technique forbidden even amongst the Uchiha clan. When the technique was activated, Danzō temporarily gained the power to turn his own body into a physical illusion, which Danzō was capable of using to negate any wound or injury he should receive from an opponent. This allowed him to survive otherwise fatal attacks while still retaining the ability to inflict physical harm to his opponent. Izanagi also gave him another benefit, after being "killed" Danzō would appear elsewhere away from danger. However, the side effect of the technique was that for every 60 seconds Izanagi remained activated Danzō would lose the use of one of his Sharingan. Also, even with Danzō's physical energy augmented by Hashirama's cells, it still took a substantial amount of chakra to sustain the technique. Danzō could also perform the Izanagi with Shisui's eye, but Madara noted that Danzō might not want to throw the eye's special dōjutsu away. Due to his lack of mastery over Hashirama's cells, Danzō's Izanagi is considered incomplete. The cells are also what allows his Kotoamatsukami to be recharged within one day after use, as without it, it would take a decade.

According to Madara, Danzō's possession of both the Uchiha clan's and First Hokage's abilities most likely meant that he was after Naruto, with the goal of controlling the Nine-Tailed Demon Fox.

Danzō was proficient with Wind Release techniques. He could exhale from his mouth powerful vacuum-based attacks that could either slash like blades or pierce like bullets. He could also use Wind Release to blow himself to safety while in mid-air. Danzō could perform Chakra Flow as well, enhancing a kunai's offensive power by pouring his wind-natured chakra through it and in the anime, it was shown he could also add wind chakra to shuriken by holding it flat on his palm, and exhaling a stream of vacuum-like chakra onto the shuriken in a pinwheel like fashion, turning them into massive buzzsaws. This greatly increases their attack range and cutting power when thrown. It should be noted that these shuriken do not lose their momentum when intercepted, and retain all their cutting power and range when blocked or redirected.

By having the First Hokage's cells integrated into his right arm, Danzō was able to use Hashirama's unique Wood Release. The implanted cells also had the additional benefit of boosting Danzō's physical energy, allowing him to sustain eleven Sharingan at once. Performing Wood Release techniques took a significant toll on his chakra, prompting him to only use it when necessary. It also appeared that he could only use the Wood Release from his right, augmented arm, although he could do so without needing hand seals. Due to his possession of the Wood Release, he might have also been capable of utilising the two elements that compose it: earth and water. However, after suffering a fatal wound during his battle against Sasuke Uchiha, Danzō lost control of Hashirama's cells, which began to grow rapidly into a large tree that threatened to engulf him. To prevent that, he disconnected his right arm, losing his Wood Release techniques.

Danzō had shown a high level of knowledge and skill when using fūinjutsu and cursed seals. To prevent his secrets from being exposed, Danzō placed binding seals on the tongues of every Root member. Should a Root member speak openly of Root and Danzō's activities, the seal would activate and instantly paralyse the member's body. The seals vanished when Danzō died. Danzō could also implement binding seals in battle, which was shown when he placed the seal on Sasuke, temporarily paralysing him. Lastly, upon his death, Danzō revealed his most powerful sealing technique, the Reverse Four Symbols Sealing Technique. The technique caused four seal symbols on Danzō's skin to exit from his body and forms a large sphere around him. Everything inside the sphere was then drawn in and imprisoned within his corpse. After the sealing was complete, the seals could still be seen on Danzō's body.

Danzō had access to a very unique summoning, a giant tapir-like creature known as a Baku, the "Nightmare-Eater". The creature had the ability to suck in objects and targets within the area in front of it. The Baku's suction could also be used to increase the power of Danzō's wind techniques. However, using the suction left the creature vulnerable against fire techniques.
