Naruto is the reincarnation of Guts (Berserk). Unlike canon, the Nine-Tails was split between his siblings — a brother and a sister — leaving Naruto with no bijū inside him. Instead, due to neglect and abuse from his parents (Minato and Kushina) and godparents (Jiraiya and Tsunade), he suffers grievous injuries early in life, losing his left arm and right eye, mirroring Guts' fate in his past life.
Rather than being fueled by Kurama, Naruto forges his own monstrous path through sheer willpower, mastery of seals, and his unique bloodline ability: Black Fire Release.

🧬 Appearance
Body: Muscular, scarred from years of neglect and training. Covered in old wounds that tell his story.
Hair: Wild and spiky blond, but darker at the tips (a remnant of his reincarnated soul's corruption).
Eyes: One vivid cerulean (burning with defiance), the other gone — scar running across it.
Prosthetic Arm: Crafted using seals, chakra-conductive metals, and blood — functions as a weapon as much as a limb.
Clothing: Dark, tattered shinobi garb reinforced with seal-inscribed leather, similar in silhouette to Guts' armor.

💀 Personality (Guts Reborn in Naruto)
Isolationist: Hates his family for their neglect; distrustful of others.
Battle-Driven: Finds meaning only in combat; thrives in danger.
Determined Survivor: No matter the odds, he refuses to fall.
Quiet but Seething: Doesn't yell or complain — his silence and intensity are more frightening than words.
Protective Rage: While bitter, he still has a deep instinct to protect the weak, especially children like he once was.

🩸 Abilities
1. Seal Mastery (Fūinjutsu Prodigy)
Learns sealing on his own, using blood and pain as catalysts.
Prosthetic arm doubles as a seal-storage unit and weapon launcher.
Can inscribe seals mid-battle with his blood (drawing them on the ground, weapons, or enemies).
Specializes in binding seals and explosive chains of runes.
2. Black Fire Release (Kokuen)
Bloodline ability: black flames that devour chakra, seals, and life force.
Unlike Amaterasu (Uchiha flames), Kokuen is living fire, behaving almost parasitically.
Can form into weapons (blades, spears) or consume enemy jutsu.
High risk: if uncontrolled, the fire eats away at Naruto himself.
3. Physicality (Reincarnation of Guts)
Brutal combat instincts; fights like a berserker.
Wields oversized weapons, sometimes forged through seals + black fire constructs.
Sheer willpower lets him fight long past human limits.
4. Hunter's Rage
When overwhelmed, Naruto enters a state like Guts' Berserker Armor frenzy — body moves on instinct, wounds ignored, black fire bleeding out uncontrollably.
Costs him more scars, but multiplies his lethality.

🌌 World Impact & Reactions
Family (Minato, Kushina, Siblings)
Shocked at how broken he has become; guilt but also resentment because they see their mistakes embodied in him.
His siblings fear him — the brother and sister contain Kurama, but Naruto feels more monstrous than either.
Jiraiya & Tsunade
Ashamed. Both failed him as godparents.
Tsunade is haunted by his injuries, realizing she let history repeat (as she failed to protect Nawaki, she failed Naruto).
Jiraiya sees his "destined child" broken and questions fate itself.
Konoha (Village)
Some pity him, others see him as cursed.
Rumors spread that he's more dangerous than his siblings, despite lacking Kurama.
ANBU report his sealing experiments with fear — he's treading forbidden ground.
Other Clans & Villages
Uchiha: Intrigued by Black Fire, wonder if it rivals their Amaterasu.
Hyūga: Fear his sealing mastery — could bypass their Byakugan defenses.
Akatsuki: Instead of targeting him for a bijū, they see him as a weapon to be captured or destroyed.

⚔️ Weapons
Dragon Slayer-Inspired Greatsword: A massive chakra-conductive blade reinforced by seals.
Sealed Arm Prosthetic: Can release stored weapons, summon chains, or erupt with black fire.
Blood Seals: Small tags etched into his own skin; he tears them open in combat to activate devastating effects.
---
🔮 Possible Ships
Anko Mitarashi: Recognizes his darkness, scars, and pain; bonds over survival.
Mei Terumi (older): Intrigued by his fire and ruthlessness.
No sibling romance — Naruto resents his family too deeply.
Ships lean toward kindred broken souls rather than lighthearted love.

🕯️ Narrative Themes
Neglect breeds monsters: Naruto became far more dangerous without Kurama's power.
Fate's cruelty: Guts' reincarnation carries tragedy across lifetimes.
Self-forged strength: Unlike his siblings, Naruto has no divine beast — only blood, pain, and fire.
