Hi I'm about to rank the top 15 shinobi alliance in Naruto base on their performance and usefulness enjoy.

• From Onoki to Sasuke, the Shinobi Alliance boasts some of the strongest fighters ever seen in anime. These are definitely the strongest of them.

• The Shinobi Alliance was created for the sole purpose of fighting the Fourth Great Ninja War to stop Obito Uchiha from taking over the world. For the first time, shinobi from all nations united to face the threat brought upon them by a masked man.

• The goal of this war was to protect the Eight-Tails and the Nine-Tails from falling into the hands of the enemies. As shinobi nations joined hands to stop the impending doom, many ninjas stepped up and did their utmost best to ensure their survival, along with that of their civilization. Here are the strongest members of the Shinobi Alliance in Naruto.

15. Mei Terumi

Mei Terumi was the Fifth Mizukage and, as such, the leader of the Village Hidden in the Mist. The Hidden Mist Village suffered under the Fourth Mizukage, and Mei had to reform the village to become a more humane place which already says something about her resolve and force of will.

On top of that, Mei has control over two of the basic elements of reality: fire and water. These are two oppositional and elemental forces that Mei can use as she pleases, and this made her one of the most immensely powerful members of the Shinobi Alliance.

14. Tsunade Senju

Tsunade ascended to the role of Fifth Hokage after the demise of Hiruzen Sarutobi. She is among the Sannin three legendarily powerful shinobi revered across the five nations. She uses her chakra to grant herself immense physical strength, can summon the giant slug Katsuyu, and has life-saving medical jutsu.

She leads the Hidden Leaf Village as part of the Shinobi Alliance during the Fourth Great Shinobi War against Tobi/Obito. She and the other four Kage took the fight to Madara himself once he is summoned and proves to be a vital part of the Shinobi Alliance.

13. Gaara

Even after the removal of the One Tailed Beast, Shukaku, Gaara retained his control over sand. He led the Village Hidden in the Sand into battle against Tobi/Obito in the Fourth Great Shinobi War. His control over sand kept him alive and active even after some of Madara's meteorite attack.

His control over a basic element and substance that covers much of the planet would already make Gaara an indispensable part of the Shinobi Alliance. However, it is Gaara who saves Naruto during a critical part of the battle against Madara and allows Naruto to go onto save the world in the shinobi war.

12. A

A is the Fourth Raikage and leader of the Village Hidden in the Clouds. He is the brother of Killer Bee and is capable of immense strength, speed, and power. His speed is on par with Minato Namikaze and strength on par with Tsunade Senju.

As a village leader, he is among the five Kages that battle Madara Uchiha directly, though he is briefly incapacitated by Madara's meteorite attack. However, he was later among the few remaining shinobi to fight Madara after he was revived late in the battle.

11. Sakura Haruno

Sakura Haruno is often discounted as a power in the ninja world, but her training at the hand of Tsunade has made her a great power in the Hidden Leaf Village, and she earns her place next to the likes of Sasuke Uchiha and Naruto Uzumaki at the end of Naruto: Shippuden.

Sakura has immense physical strength, powerful medical jutsu, and the ability to summon Katsuyu and the other giant slugs that had formed a pact with Tsunade. She is protected from the Infinite Tsukuyomi by Sasuke, and she is among the small team of shinobi that could battle Kaguya during the very final stages of the Fourth Great Shinobi War.

10. Onoki

Also known as the 'Fence Sitter', Onoki was one of the strongest shinobi in the entire Naruto Series, and even though he was old during the war, he was still a monster in combat. By virtue of his wisdom, even Madara Uchiha recognized Onoki as the main threat among all the Kage.

Onoki was a master Earth-style Ninjutsu user, but his real strength lay in his ability to use the Kekkei Tota known as Dust Release. Although his abilities were severely hampered because of his age, Onoki performed some of the most incredible feats, such as holding off two meteors and saving an entire platoon of shinobi all by himself

9. Edo Tobirama Senju

Reanimated by Orochimaru on Sasuke's asking, Tobirama joined the Fourth Great Ninja War very late but played a key role in it once he joined. As a master of an arsenal of Ninjutsu, most of which he had created on his own, Tobirama led a large chunk of shinobi in the war.

He did his part by fighting against the Ten Tails, and even trying his luck against the Ten Tails Jinchūriki, Obito Uchiha himself. While Tobirama was definitely strong, he certainly didn't display a good showing in the war, primarily because all those who he had to fight, such as Obito and Madara, were astronomically more powerful than him.

8. Edo Itachi Uchiha

Just like the rest of the Akatsuki, Itachi Uchiha was also reanimated by Kabuto Yakushi during the 4th Great Ninja War. According to Kabuto, Itachi was his finest piece among all the other Edo Tensei shinobi. Smart as he is, Itachi broke free from his control and was key in stopping the Edo-Tensei by defeating Kabuto Yakushi and reducing the number of enimes by half.

Itachi proved himself to be a competent shinobi by, once again, saving the world from the shadows.  He did his part, yet he didn't take any credit for it, just as he did when he was alive. Truly, Itachi was no less than a Hokage.

I'll continue it later or maybe tomorrow the part II of this cause I'm tired right know enjoy reading.
