The Akatsuki was an organization that compromised of some of the most powerful rogue ninjas in Naruto. Led by several leaders over the years, they were focused on mainly during the reign of Nagato Uzumaki, an orphan from Amegakure. Under him, the members of the Akatsuki were divided into two-man teams, with each team being handled missions appropriate to them.
While the strength of the teams was, more or less, frightening in every case, some teams were undeniably stronger than the others. Here are all the known Akatsuki team pairs that we've seen in Naruto ranked by strength.
8 Black Zetsu and White Zetsu
Also known simply by the name of Zetsu, this team compromised of two Zetsu halves, one of which was black, the other being white. The black half of Zetsu was the will of Kaguya Otsutsuki, while the white was simply the product of Infinite Tsukuyomi. Together, they worked as the surveillance unit of the Akatsuki.
Therefore, it wasn't expected of them to be able to use some powerful techniques. Zetsu was exceptionally good at tracking ninjas and collecting information, but when it came to fighting, he was, undoubtedly, the weakest in the entire Akatsuki.
7 Kakuzu and Hidan
Kakuzu and Hidan's team was arguably the most disconnected team in the entire Akatsuki. Due to his habit of killing his teammates, Kakuzu was paired with Hidan, a guy who he couldn't kill since he was immortal. Their fighting capabilities were more than decent, with Kakuzu being the stronger one among the two. Hidan's strength was his immortality, but other than that, his skills weren't all that great.
Together, this team was charged with several missions, one of which was the capturing Yugito Nii from Kumogakure. Furthermore, they also fought Konoha shinobi and were primarily responsible for killing Asuma Sarutobi. Despite that, Kakuzu met his end at the hands of Kakashi, while Hidan was taken care of by Shikamaru Nara.
6 Juzo Biwa and Itachi Uchiha
Itachi Uchiha joined the Akatsuki upon defecting from Konoha after murdering his clan. At a certain point, he was teamed up with Juzo Biwa, a former Mist Ninja who was also one of the Seven Swordsmen of the Mist. Undoubtedly, this team was very powerful, yet at the same time, their weakness was the lack of coordination.
While they did possess decent strength together, their team didn't last long enough as the Fourth Mizukage, Yagura Karatachi saw to it that Juzo Biwa died. Itachi, being the stronger of the two, defeated Yagura Karatachi and was later paired up with Kisame Hoshigaki, who also belonged to the Hidden Mist Village.
5 Sasori and Deidara
A pair obsessed with "art," Sasori and Deidara were the first ones among the Akatsuki to make their move in the Naruto Shippuden series. Being given the mission to capture the Fifth Kazekage, Gaara, the two saw to it that the mission succeeded without much trouble. Although the two had their differences, Sasori and Deidara's team worked quite well together.
While Sasori held the ability to manipulate puppets like a pro, Deidara used explosions as his art, making them a difficult team for anyone to fight against. With Sasori's early death, Deidara was later paired up with Tobi of the Akatsuki.
4 Deidara and Tobi
After the death of Sasori, Deidara was paired with Tobi, who appeared to be a rather mysterious individual at the time. Initially, Deidara saw him as his disciple, little did he know that Tobi was the one pulling the strings from behind the scenes. Together, the two hunted down one of the Tailed Beasts, Isobu the Three-Tails, and managed to seal it without much trouble. When it comes to the strength of this team, it is unfortunate that we didn't get to see them fight together properly.
Nevertheless, both Deidara and Tobi were strong enough to fight against Kage level shinobi. Tobi, being a student of Madara Uchiha, had previously fought against the likes of Minato Namikaze, while Deidara nearly killed Sasuke Uchiha in battle. Truly, Tobi and Deidara made a fearsome team.
3 Orochimaru and Sasori
Both Orochimaru and Sasori served as one of the earliest members of the Akatsuki, and thus, were made into a team before the events of the Naruto even began. Together, they formed a very intriguing team, and although little was seen of the two on missions, it goes without saying that with one of the legendary Sannin and a master puppeteer, the team would be dangerous. Although this team had loads of power and talent, they barely ever agreed with one another and were always at odds.
In fact, Sasori bore a grudge against Orochimaru for some reason and even placed Kabuto as a spy under the ranks of the latter. Little did he know that Orochimaru had already figured him out as he was superior to him in almost every way.
2 Nagato and Konan
The first Akatsuki team to exist under Nagato's reign was that of him and Konan. Together, the two aimed at collecting all the Tailed Beasts to ultimately create world peace. With Nagato claiming to be a God, Konan was his Angel. The two were exceptionally powerful, with enough might to completely take over Amegakure after the death of Yahiko and turn it into the Akatsuki base.
Their powers far surpassed the likes of the legendary Sannin, and even the mightiest of shinobi would've faltered against them, Jiraiya being the prime example of that. This team tried to recover the Nine-Tails from Konoha but failed in doing so.
1 Itachi Uchiha and Kisame Hoshigaki
After Juzo's death, Itachi Uchiha was partnered with Kisame Hoshigaki, primarily because both of them had massacred their fellow shinobi. Out of all the Akatsuki members, this team had the best balance and their strength was the highest as well. Together, they were tasked with several missions, such as capturing the Four Tails, which they managed to pull off successfully.
Often, the two used to spar together to hone their skills. With Itachi Uchiha being one of the strongest shinobi, and Kisame Hoshigaki being a Tailed Beast level ninja, it's no surprise that this team tops the list of the strongest Akatsuki teams.
