Start with potency
We know the bijuu are all relative to eachother since they can injure Gyüki who has the durability to tank his own Bijuudama. Who is currently small country level via this calculation.

PT1 OROCHIMARU
That he can destroy a country in the first databook via his destructive power alone.
https://narutoversity.wordpress.com/first-databook-character-files/
Also he used to be apart of the Akatsuki who were tasked to defeat bijuu and are literally stated to be stronger than Jinchuriki.
PT1 HIRUZEN
Hiruzen can also physically push back kurama to outside the village who has Small Country level AP, he used Monkey King Enma to do this and this summoning can't grow weaker. Orochimaru can trade hits from it. Hiruzen states he is stronger than him. Hiruzen at this time was stated stronger than the other 4 Kage like the 4th Raikage who in his jounin days helped the third Raikage restrain the 8 tails. Even cutting off his horns etc. He is stated to have bijuu level chakra and could fight Killer B. Being Raikage means your the strongest in your village meaning he’s superior to Killer B.
4th RAIKAGE
Harmed 8 tails. Superior to MS Sasuke who fought killer B. As Raikage is the strongest in his village. Since that’s how the cloud functions.
TSUNADE
Tsunade is physical stronger than The 4th Raikage since she beat him in an arm wrestle and according to Madara, she surpasses A in physical strength and was able to break Madara's Susanoo ribcage.
She’s stated to be a match for the other sannin in every regard.
ONOKI
Madara who states onoki to be the most problematic. Fought with multiple Complete Susano'o. He tanked the collision between the two Tengai Shinsei that seems to be Perfectly inelastic collision. The Tengai Shinsei calculated small country level+
https://vsbattles.fandom.com/wiki/User_blog:Kepekley23/Naruto_Revision_Calcs It is also stated he could vaporise Genbu the Turtle Island here's the calculation to that hypothetical which is small country level.
https://vsbattles.fandom.com/wiki/User_blog:Webcamparrot/Onoki_and_Genbu
GAARA
Gara being a jinchuriki who scales to Gyüki and Mei also scaling to the other kage.
His sand was so strong that Raza thought Gaara was using the one tails. He was evenly matched with Gaara. Raza used to subdue the One tails.
Gaara had effective feats against Madara and Ms Saskue.
Akatsuki It's stated the the Akatsuki are as strong as the Jinchuriki in the databook who should all be small country level since they can injure Gyüki who has the durability to tank his own Bijuudama.
https://cdn.discordapp.com/attachments/463881402598031371/582258187403788308/image0.png
V2 bijuu are as strong and can harm kcm1 Naruto.
HIDAN
Considered the biggest threat to konoha by the summary at the time. Relative to Kakashi. Who could fight 30% Itachi. So should be at least 30% of bijuu level. Also Kakazu considered Hidan unkillable so couldn’t physically get rid of him. Despite Hidan being susceptible to being chopped up and die from malnutrition.
DEIDARA
Deidara would've destroyed Sunagakure had Gaara not blocked it). He can use c0 that is calculated small country level.
https://vsbattles.fandom.com/wiki/User_blog:Dariel_Senju/C0_crater_calculation?comments_page=1This was done by a heavily weakened Deidara with hardly any chakra. He knows it’s diameter because he’s an analytical genius according to the databook. The fact base Hebi sasuke and manda survived despite getting hit by it means they scale and shows that Deidara’s attack wasn’t him at his strongest since he could scale above that weakened Hebi sasuke and fp.
SASORI
Sasori is stated Deidara's superior and defeated the 3rd Kazekage. The strongest Kazekage. Making him superior to raza who could subdue the one tails. Possessing the iron sand. The sand’s strongest weapon. Superior to the one tails.
KAKAZU
Kakazu Has defeated the 2 tails jinchuriki. During this he tanked a direct attack from the full 2 tails perfect jinchuriki and also tanked another attack that blew up the building they were in and destroyed a large portion of a mountain. For proof that kakuzu tanked it the panel following their battle displays a completely unharmed and uncaring kakuzu. He should scale to the bijuu since he doesn't rely on hax to beat his opponents and was selected to take out Bijuu. Also remember Naruto only beat him once he was fatigued and had lost hearts and durability negged by the rasenshuriken.
KONAN
Konan has paper explosions that are stronger than standard explosive tags, capable of injuring Obito someone whom Minato stated Naruto needed the full Nine Tail in order to defeat. She could most likely take out jinchuriki and Bijuu. Also even a smaller amount of paper bombs could harm Hidan who is part I kakashi level.
KISAME
Kisame is stated a tail beast without a tail so should be bijuu level straight of the bat in raw chakra and potency. He Matched and is comparable to Version 2 Killer B and absorbed most of his chakra with his Samehada). Without samehada, his transformation and misjudging 7th Gate Guy's Hirudora that dwarfs the island they’re on. And hurt Madara's susanoo ribcage with it.

ITACHI
Itachi scales above Deidara since he scales to or beyond Hebi Sasuke. Also he scales above Orchimaru who in part I couldn't beat teen Itachi. Kisame considers Itachi the stronger between them. And is afraid of facing MS Itachi in generations which is canon.
In Itachi midnight he forces a pact with Obito and both directly acknowledge eachothers power. Note both should have genjustu resistances to eachother and Itachi doesn’t have the Amaterasu yet so this is a contest of power.
Edo
He could match KCM Naruto and Killer B if not outclass them. With his Susano'o and Amaterasu one-shoted Edo Nagato. Who is stronger than the 6 paths of pain.
He is the stated to be someone who EMS sasuke had just reached.
PAIN
Pain fought v2 Saiken who should be comparable to the other v2 bijuu who could harm kcm1. Pain also fights Sage Mode Jiraiya and Naruto. The whole point of him at his group was to defeat and capture bijuu. He also fought partial transformation Naruto when pain was fatigued. As the Akatsuki leader should be at least relative to the other members. His chibaku Tensei was calculated small to normal country level.
https://vsbattles.fandom.com/wiki/U...agato's_Chibaku_Tensei_&_Speed_&_Naruto's_FRS
Edo
As Nagato he could simultaneously fight KCM Naruto and Killer B if not outclass them. As well as fight Itachi.
OBITO
Obito was able to fight against Minato. Minato who could cut through Killer B's partial transformation and fought kurama. Who are small country level. It was stated that if Konoha were under a direct attack from Orochimaru, Minato would be the only one able to defeat him). Minato states Naruto needs the nine tails full power to beat him. Also that he’s a bigger threat than pain.
HEBI AND MS SASUKE
Ms Saskue fought some of the kage forcing the 4th Raikage to cut his arm of and fought killer B who he cut through when transformed into Gyüki. So should be small country level, since hebi saskue was potentially rivalling the Akatsuki.
JIRAIYA
Jiraiya who Pain stated that he would've lost to Jiraiya had he known the secret of the Rinnegan and came prepared for him and should scale to Tsunade. He was most likely in base when injured by 4 tailed Naruto since he wouldn't of had time to go into sage mode.
SAKURA
Sakura harmed Sasori. She oneshot one of Pain's centipede summons, which should be comparable to his other summons that have fought Gamaken, a frog who is comparable to Gamabunta, another frog who could fight Shukaku who is relative to Gyüki.
Pains summonings also restrict saiken the six tails v2.
She also surpassed Tsunade according to Hashirama in her base who should be small country level. She then rivals fatigued kcm 2 Naruto according to the guidebooks.
She then get stronger throughout the war arc but I’ll bring that up later.
MINATO
Minato in his base should be small country level. It was stated that if Konoha were under a direct attack from Orochimaru, Minato would be the only one able to defeat him). The 4th Raikage saw him as a rival. Who fought kurama.
7th Gate guy for reasons mentioned earlier.
This will reduce the gap between mountain/island level and multi continental so progression is more linear.
GUY
6th gate. He beat a 30% Kisame.
7th gate. His Hirudora dwarf an Island that Onoki mistook for normal land/country due to its size.
Higher scaling will be addressed later.
DARUI
Should scale to the 4th Raikage for fighting G and K.
Also he "mastered" his ninja tool which should put him above the Gokage according to the databook. Only with his tool however.
KAKASHI
Fights 30% Itachi.
Fights Hidan.
Fights Pain with mental amp.
Fights the v2 bijuu who he literally cuts.
Higher scaling will be addressed later.
