how strong is the kyubi mode compared to sage mode

[portgas d luffy]

i think of them as equals

no biju mode !!!

[Uchihagodzzz]

Sage mode isn't anywhere near as powerful.

[ThePieness]

Kyuubi mode imo
because has way more perks, the only thing SM has that KM doesn't is extremely enhanced strength.

[portgas d luffy]

can kyubi mode sumon frogs and stuff?

[Unatural]

can kyubi mode sumon frogs and stuff?

Yup

[★Techmo]

Kyuubi mode has a whole lot more rasengan variations.
Way faster faster than raikage.
Mini tailed beast bmb.

[xzodiacx]

the difference is: one is frog style, the other is fox style xD

[★Chaos.]

Well....as of the appearance....Sage mode wins this!

Now for the combat stats!
Sage Mode!▼

Toad Sage Mode Edit
Advantages Edit

There are numerous advantages while using toad Sage Mode. These include:

The user's physical strength, speed, stamina, reflexes, and durability dramatically increase.
The user's ninjutsu, genjutsu, and taijutsu become more powerful.
The user can harness the natural energy surrounding them, turning it into an extension of their body, which increases the reach of their attacks.
The user gains the ability to sense chakra around them.

Disadvantages Edit

There are a few disadvantages while using toad Sage Mode. These include:

If the user draws in too much natural energy in the attempt to initiate Sage Mode, they run the risk of transforming into a toad, then into stone. If the transformation is completed, it cannot be reversed.
In order to gather enough natural energy to initiate the transformation into Sage Mode, the user must remain perfectly still. Because of that, the user can be an easy target for an opponent.
Because the user needs to move during combat, the senjutsu chakra cannot be replenished, which means the user can't stay within this state for extended periods of time.
The second and third weaknesses mentioned above can be bypassed through the Sage Art: Amphibian Technique, where one Sage gathers chakra for another or as in Naruto's case, shadow clones can be used for the same purpose.
After Sage Mode has ended, the user appears to experience exhaustion.

kyuubi Mode!▼

With Kurama's power under his control, Naruto's strength is significantly increased to the point where he can push a fully formed Tailed Beast Ball through a multiple layered barrier with one arm,[23] and, with help from Killer B in his full Eight-Tails form, knock down Tobi's Demonic Statue of the Outer Path with an uppercut. He could also neutralise White Zetsu with a single blow despite their durability. B had trouble determining if Naruto's speed was from the Body Flicker Technique, as all he saw was a "yellow flash" when Naruto attacked Kisame Hoshigaki.[24] In this form, Naruto was able to surpass the speed of a fully charged A, who was currently the fastest shinobi in the world with Minato's death.[25] Though he can still feel pain, this form's chakra shroud gives Naruto a great amount of protection; regular swords are unable to pierce it, extreme heat temperatures slightly burn him,[26][27] and extreme physical attacks do little damage.[28][29] When he mastered the Tailed Beast Ball in Tailed Beast Mode, Naruto was finally able to use it in his Nine-Tails Chakra Mode, showcasing the Super Mini-Tailed Beast Ball against Tobi, which causes a powerful explosion in the distance after being launched by a chakra arm.[30]

The shroud's chakra arms gives Naruto greater range of attacks as well as greater dexterity and manoeuvrability to his fighting style without the use of shadow clones. He is able to use the chakra arms to push himself off a platform[31] and to extend his reach,[32] where he would otherwise create a shadow clone to use as a landing point in mid-air.[33] or to propel him through the air.[34] Naruto has also used the chakra arms to create new Rasengan variants, such as the Spiralling Strife Spheres, Spiralling Absorption Sphere and the Planetary Rasengan. The power of his techniques have become so great that, unless they already have some inherent durability, such as the Third Raikage, reincarnated ninja have a hard time regenerating.[35]

Like his predecessor, Mito Uzumaki, Naruto also gains Kurama's ability to sense negative emotions, something that not even the best sensor-type ninja can do.[36][37] In addition, he is capable of sensing Kurama's chakra signature, even while he was inside a chakra isolation chamber within the Falls of Truth.[38] Due to having Kurama's Yang chakra in this form, Wood Release techniques will react to the chakra's life-giving properties and mature into full-grown trees within a matter of seconds, either by contact or close range.[2][39][40]
The risks involved in the usage of Nine-Tails Chakra Mode.

However, using the Nine-Tails Chakra Mode was a huge risk as Naruto had to temporarily "shelve" his own chakra in order to use Kurama's, which allowed the fox to automatically drain Naruto's own chakra. If Kurama managed to take all of Naruto's chakra, Naruto would die. In addition, Gyūki advised him against the use of the Shadow Clone Technique, as Kurama would absorb every portion of Naruto's chakra even faster for each clone he made. Moreover, Naruto also had to be careful about the amount of time he spent in this mode as Gyūki stated that there was a limit to how much chakra Naruto managed to pull away from Kurama, implying that the untainted chakra would eventually run out.[41] Despite these risks however, once Naruto was on the battlefield, he deployed several of his shadow clones while in this mode to the different divisions to confront the enemy White Zetsu, indicating that the risks associated with this form are not instantaneous.[42] Naruto was able to stay in this form for an entire night and most of the morning during the Fourth Shinobi World War, though Gyūki noted that at some point Kurama had purposely stopped taking Naruto's chakra.[43]

So as for stats...i think Kyuubi mode is better...

[Naruto N. Uzumaki]

kyuubi mode is better then sage mode in almost every aspect

[ulqui0rra]

they seem equal to me
in sage mode naruto looks more tougher
in km faster
km has one advantage he can sense evil feeling and read thoughts
sm has another he can sence the surrounding can become one with it

[VariaBossX]

sage mode naruto is limited to five mins per battle, kyubi naruto clone soloed 5,000 white zetsu summoned those frogs without using a hand seal( i presumed) and beat A's speed once.
