Sung Jin-Woo is the main character of Solo Leveling, and when the series started, he was the weakest Hunter in the world. He was killed in a double Dungeon, but an unknown entity saved him. Sung Jin-Woo can now increase his strength by completing tasks and defeating enemies, and there is now no theoretical limit to his strength. As a result, Sung Jin-Woo can definitely defeat several characters from Naruto.
All of the Naruto characters that Sung Jin-Woo can beat are skilled ninja with unique abilities. Many of them are from the Hidden Leaf Village, but others once belonged to other villages. Several of these characters are Jonin-level, and the argument can be made that a few are Kage-level. Sung Jin-Woo can even defeat an Akatsuki member under the right circumstances.
10 Zaku Can Be Overwhelmed By Sung Jin-Woo's Skills
First Appeared in Naruto Episode 21: "Identify Yourself: Powerful New Rivals"
Zaku was one of the enemies introduced during the Chunin Exams. He was one of the first ninja to possess scientific body modifications. These modifications came in the form of hollow air tubes that extended through his arms. As a result, Zaku can fire pressurized air and sound from his hands.
These pressurized shots can deflect ranged attacks, and they can slow boulder-sized objects. If Sung Jin-Woo gets hit by one of these shots, he will sustain a good amount of damage. Unfortunately, Zaku's shots go in one direction. Sung Jin-Woo can avoid Zaku's attacks with Dash, and he can follow it up with a clean dagger strike. Sung Jin-Woo could also get behind Zaku and use his strength to break the modified arms - just like Sasuke did in the Forest of Death.
9 Shino's Insects Would Be Useless Against Sung Jin-Woo
First Appeared in Naruto Episode 1: "Enter: Naruto Uzumaki!"
Shino mainly uses Kikaichu beetles during combat. These beetles can swarm an opponent will consume their chakra until they are knocked unconscious. During the Fourth Great Ninja War, Shino revealed that he can also use kidaichu beetles. If these insects are placed on another host, they will rapidly grow in size while devouring the new host's chakra and body.
Sung Jin-Woo does not use chakra though, so Shino's insects would be ineffective. Shino relies on his insects, and as a result, his melee skills are a bit lacking. Sung Jin-Woo can simply dash through the insects to strike Shino. Since Sung Jin-Woo does not have chakra, Shino's insects would not be able to detect him if he uses Stealth. This means that Shino may not have time to react to Sung Jin-Woo's assassination attack.
8 Jirobu's Physical Strength Can Be Outmatched
First Appeared in Naruto Episode 68: "Zero Hour! The Konoha Crush Begins!"
As one of the Sound Four, Jirobo was considered one of Orochimaru's elite bodyguards. In terms of physical strength, he was the group's strongest member, and he could use that strength to lift massive sheets of rock. Jirobo was branded with Orochimaru's Curse Mark, and he could use the Level 2 Transformation.
This transformation gave Jirobo a demon-like appearance, and it significantly enhanced his physical strength. The original Sung Jin-Woo would die if he were hit by one of Jirobo's Level 2 punches, but the current Sung Jin-Woo is much faster. He can easily avoid Jirobo's attacks, and he can still cut Jirobo with his dagger. With enough leveling, Sung Jin-Woo can stop Jirobo's punches with his bare hand, and he can theoretically take Jirobo out with a well-placed punch of his own.
7 Kiba's Strongest Jutsu Is Basically A Weaker Version Of Cerberus
First Appeared in Naruto Episode 1: "Enter: Naruto Uzumaki!"
Like other members of the Inuzuka Clan, Kiba goes into battle with his own ninja dog. He and Akamaru are inseparable, and they can fight in unison with each other. Thanks to the Beast Mimicry Technique, Akamaru can transform into Kiba, and they can perform a coordinated rotating attack that can land multiple blows.
This attack is fast, but Sung Jin-Woo should be able to dodge it with Dash. Kiba and Akamaru can also transform into a massive two-headed or three-headed dog. This transformation is actually Kiba's strongest jutsu. Sung Jin-Woo has already defeated a three-headed dog boss named Cerberus - who was immune to the Bleed and Paralyze effects of Sung Jin-Woo's dagger. Kiba's transformation is not immune to these effects, which means that Sung Jin-Woo can take it down much easier.
6 Choji's Expansion Jutsu Can Be Countered With Speed
First Appeared in Naruto Episode 1: "Enter: Naruto Uzumaki!"
Choji is now the sixteenth head of the Akimichi Clan, and he has mastered the clan's secret techniques. He can use the Expansion Jutsu to enlarge specific body parts, but he can also increase his overall size until he becomes as tall as a mountain. While Choji is in his giant form, all of his physical attacks deal significantly more damage.
In some instances, Choji can convert his body's calories into chakra. This Butterfly Mode allows him to fight on par with the Gedo Statue for a short time. At first, Sung Jin-Woo might be intimidated by Choji's size, but he will quickly realize that Choji's size can be countered with speed. Sung Jin-Woo can dash around Choji's body, and slash him at the same time. Despite his size, Choji can still succumb to the Venom Fang dagger's effects, and he will eventually be immobilized. Once Choji is unable to move, Sung Jin-Woo can deliver a finishing blow.
5 Sai's Ink-Based Jutsu Is Easily Countered
First Appeared in Naruto: Shippuden Episode 21: "Return of the Kazekage"
Sai was a member of Root - a special Anbu sub-division that carried out dark missions. He was considered the strongest Root member of his generation, and Danzo believed he was skilled enough to kill someone as strong as Sasuke Uchiha. Sai possesses a unique fighting style that makes use of his artistic nature.
Thanks to the Super Beast Scroll Technique, Sai can use his chakra to bring anything he draws to life. He typically creates multiple animals that can attack his opponents. Unfortunately, these ink beasts can be destroyed if they are hit just once. At his current level, Sung Jin-Woo can neutralize Sai's main jutsu. Sai may be a skilled Anbu-level ninja, but even he cannot keep up with Sung Jin-Woo's Stealth and Dash combo. Even if Sai tries to intercept Sung Jin-Woo's attack with a kunai or sword, he will be overwhelmed by Sung Jin-Woo's superior strength.
4 Shikamaru May Be Smart But He's Not Much Of A Fighter
First Appeared in Naruto Episode 1: "Enter: Naruto Uzumaki!"
Shikamaru is one of the smartest ninja in history, and he has used his intelligence to restrain or outright defeat various opponents. As a member of the Nara Clan, Shikamaru can use the Shadow Possession Justu - which allows him to merge his shadow with his target's. Even someone as strong as Sung Jin-Woo would be restrained for a time if Shikamaru successfully merges their shadows.
Shikamaru can also use his shadow to strangle Sung Jin-Woo, or he can use his shadow to impale Sung Jin-Woo multiple times. If Sung Jin-Woo uses Stealth, he should be able to avoid the Shadow Possession Jutsu. He can then use Dash to slice Shikamaru apart. Shikamaru is not much of a melee fighter, so he likely won't react in time to dodge Sung Jin-Woo's attacks.
3 Zabuza's Silent Killing Technique Can Theoretically Be Countered By Sung Jin-Woo's Skills
First Appeared in Naruto Episode 6: "A Dangerous Mission! Journey to the Land of Waves!"
Prior to his defection, Zabuza was part of the Hidden Mist Village's legendary Seven Ninja Swordsmen. He was actually part of the group's strongest generation. He wielded the Executioner's Blade - a large broadsword shaped like a butcher's knife. Zabuza was known as the Demon of the Hidden mist, and he mastered the Silent Killing Technique.
If it wasn't for Naruto and Sasuke's quick thinking, Zabuza would have killed Kakashi - a future Hokage. Even if Zabuza uses the Hidden Mist Jutsu, Sung Jin-Woo can negate the Silent Killing aspect by using Stealth to conceal his presence, and he can use Dash to escape the mist. He can also use his Necromancy to summon soldiers that can distract Zabuza while Stealth is active. In this instance Sung Jin-Woo could take the opportunity to deliver a silent killing blow of his own. If they engage in a clash of blades, Sung Jin-Woo's superhuman strength will give him an edge, and if he manages to nick Zabuza once, he will gain a permanent advantage.
2 Hidan Can Be Immobilized By Sung Jin-Woo's Dagger
First Appeared in Naruto: Shippuden Episode 71: "My Friend"
Hidan was part of the Akatsuki, and he was a devout follower of the Jashin religion. Thanks to the religion's forbidden techniques, he gained a form of immortality, but he also learned how to use a deadly curse. If Hidan consumes his target's blood, he will become a human voodoo doll. Hidan and his target will then share every injury that the other sustains. That being said, the voodoo doll aspect will only trigger if Hidan stands in a Jashin symbol that was placed on the ground.
If Hidan successfully activates this curse on Sung Jin-Woo, no amount of levels can save him from a pierced heart. Sung Jin-Woo is very perceptive, so he may figure out that the symbol on the ground is important. He can just fight Hidan head-on to keep him away from the symbol. Sung Jin-Woo's dagger may not be able to kill Hidan, but it can still paralyze him. If Hidan is immobilized, Sung Jin-Woo can simply remove Hidan's head, so he is no longer a threat.
1 Sakura Is One Of The Strongest Female Ninja In History
First Appeared in Naruto Episode 1: "Enter: Naruto Uzumaki!"
Sakura was trained by Kakashi and Tsunade, and she has become one of the strongest female ninja in history. She can concentrate chakra into her fists - which gives her superhuman strength. Even at his current level, Sung Jin-Woo would probably get taken out by one of Sakura's punches.
Fortunately, the Dash skill should make Sung Jin-Woo faster than Sakura. He should be able to dodge her attacks and slash at her at the same time. Sakura has mastered Mitotic Regeneration, which essentially makes her immortal for a short time. This technique would not stop her from being paralyzed by Sung Jin-Woo's dagger. If Sakura is immobilized, Sung Jin-Woo can finish her off without having to worry about her monstrous strength.
