Sun God Sage Mode

Sage Mode is the result of using natural energy along with a ninja's normal chakra in perfect balance to drastically empower their abilities.

Usage
A prerequisite to being able to use senjutsu is that the user must have a large reservoir of chakra themselves in order to manipulate the natural energy.

Advantages
There are numerous advantages while using the Flame Elements 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.
 * The user becomes almost impervious to fire of almost all types.

Disadvantages
There are a few disadvantages while using 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 being possessed by the Amaterasu's Flames and burned to nothing. 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.


 * After Sage Mode has ended, the user appears to experience exhaustion.

Imperfect Hell's Sage Mode
Honō Uzumaki is not yet able to properly balance his own chakra with natural energy, resulting in him using an imperfect form of Sage Mode. As a result of the imbalance (and the imperfect nature of his transformation), Honō's face was completely made of fire.

Perfect Hell's Sage Mode
As a workaround, Hono has some of his shadow clones gather natural energy elsewhere while he fights. Once he has run out of his own senjutsu chakra, he has one of the clones disperse, giving him the clone's natural energy and allowing him to enter Sage Mode again. This method limits the maximum number of shadow clones that Naruto can create to five for as long as the clones are gathering natural energy, as anything more would interfere with their focus. To make sure he has enough shadow clones for use in battle, Naruto has only two shadow clones gather senjutsu chakra, allowing him to enter Sage Mode a total of three times. Naruto also stated that it is possible to lengthen the time he is in Sage Mode. He now can enter Sage Mode in just a few moments.
