Formation principle identified	168	Feng identifies the required 1:1:1 balance of Natural Energy, physical energy, and spiritual energy.
Natural Energy observation breakthrough	172	Three-Tomoe Sharingan users can vaguely perceive Natural Energy, allowing Feng and Izumi to observe it gathering around Yaku Daibu.
Sage Mode mastery	175	Feng successfully cultivates Senjutsu after nearly three years of preparation, training, safeguards, and access to a Natural Energy-rich environment.
Hybrid transformation	175	Feng combines Sage Mode with Lightning Release Chakra Mode to create Sage Art: Super Saiyan Mode.
Combat-ready deployment	175	Senjutsu-enhanced attacks overpower Fugaku’s Fire Release and let Feng ignore Hashirama’s Bringer-of-Darkness Technique.
Three-fold enhancement	288	Feng stacks Sage Art: Super Saiyan Mode with Nine-Tails Chakra Mode and Perfect Susanoo during his battle with the Six Paths of Pain.
Anti-absorption application	289	Feng deliberately feeds Senjutsu Chakra to the Preta Path; its inability to control the Natural Energy causes it to deform and explode.

Formation and Cultivation

Senjutsu Chakra is produced by precisely balancing Natural Energy with physical and spiritual energy. Natural Energy alone is dangerous: excessive absorption petrifies ordinary people rather than strengthening them. 166 168

Feng pursued Senjutsu because it can strengthen chakra-based abilities and affect Ōtsutsuki opponents, against whom ordinary ninjutsu is considered ineffective. 115

His research relied on the Tsuchigumo Clan’s forbidden art. Yaku Daibu’s implanted Spirit Orb can absorb Natural Energy without petrifying and can extract excess Natural Energy from others before their condition becomes fatal. 168 172

Natural Energy Perception

Feng, Izumi, Mei Terumi, and the Royal Guard initially failed to sense Natural Energy even inside a cavern saturated with it. 172

The breakthrough came when Gui Tai evolved his Sharingan to Three-Tomoe and discovered that it could vaguely see Natural Energy. Feng and Izumi confirmed this by observing the energy surrounding and entering Yaku Daibu. 172

• Three-Tomoe Sharingan provides visual observation rather than direct sensory perception. 172
• Feng uses Shadow Clones during experimentation to avoid exposing his true body to uncontrolled Natural Energy. 172
• Yaku Daibu acts as a safety measure by extracting Natural Energy from the clones before it can be transferred back upon their dismissal. 172

Properties

Chakra Enhancement

Senjutsu Chakra substantially strengthens Feng’s physical abilities, perception, chakra techniques, and resistance to genjutsu. In Sage Art: Super Saiyan Mode, senjutsu lightning surrounds his body, his hair turns golden, and gray-black markings appear around his eyes. 175

• Enhances Feng’s sensory perception enough to clearly track the Six Paths of Pain in combat. 288
• Strengthens sword techniques, including Sage Art: Sky Severing. 175
• Supports advanced Rasengan variants such as Sage Art: Spiral Stars, an Iron Release-infused Rasengan capable of pulverizing the Naraka Path. 288
• Allows Feng to resist the Bringer-of-Darkness Technique without being affected. 175

Hybrid Sage Art: Super Saiyan Mode

Feng combines Sage Mode with Lightning Release Chakra Mode, creating a self-developed transformation resembling Super Saiyan 2. 175

• Surrounds Feng with senjutsu-infused lightning. 175
• Can be stacked with Nine-Tails Chakra Mode for greater combat output. 288
• Rapidly heals injuries when used alongside Nine-Tails Chakra Mode. 289

Sage Art: Perfect Susanoo

Feng can apply Senjutsu Chakra to his Perfect Susanoo, dramatically increasing its destructive power. 289

• Destroyed the core of Nagato’s Planetary Devastation with a Susanoo cross-slash. 289
• Can be used alongside Flying Thunder God movement and Nine-Tails Chakra Mode. 288 289

Natural-Energy Overload

Senjutsu Chakra is hazardous to targets unable to control Natural Energy. Feng exploits this weakness against chakra absorbers. 289

• The Preta Path absorbed Feng’s chakra voluntarily offered through its absorption technique. 289
• The Natural Energy within the transferred Senjutsu Chakra caused the Preta Path to stiffen, swell, deform, and explode. 289
• The explosion also destroyed the nearby Human Path. 289

Longevity Potential

Integrating Senjutsu Chakra into a modified body can extend that body’s lifespan. Feng lists this as part of a potential longevity method based on cultivation and body modification. 116

Limitations

• Natural Energy must remain balanced with physical and spiritual energy; incorrect absorption risks petrification. 166 168
• The Tsuchigumo inheritor can remove excess Natural Energy, but the rescue must occur quickly and is dangerous if delayed. 166
• Yaku Daibu’s Spirit Orb has no known energy-storage limit, but his body does; excessive stored Natural Energy must be released immediately or may become uncontrollable. 168
• Feng initially requires at least ten seconds to gather sufficient Senjutsu Chakra before entering Sage Mode. 256
• Feng’s early research could not proceed until the Three-Tomoe Sharingan provided a way to observe Natural Energy. 172

Known Users

• Uchiha Feng — Mastered Senjutsu Chakra and developed Sage Art: Super Saiyan Mode; later combines it with Nine-Tails Chakra Mode and Perfect Susanoo. 175 288
• Orochimaru — Possesses a self-researched Sage Mode and spreads his Senjutsu Chakra over Fugaku’s Susanoo during their battle. 177
• Hashirama Senju — His use of Senjutsu Chakra is known to Feng through historical and future knowledge. 108

Trivia

• Feng considers Senjutsu one of the few powers guaranteed to counter the Ōtsutsuki. 115 163
• Feng’s Sage Art: Super Saiyan Mode visually resembles Super Saiyan 2, while its gray-black eye markings resemble Yaku Daibu’s Spirit Orbs. 175
• Feng’s failure to consider the Sharingan’s ability to observe Natural Energy leads him to call himself an idiot after Gui Tai’s discovery. 172
