Sung Jin-Woo is the main character of Solo Leveling, and he was once the weakest Hunter in the world. He was killed in a unique Dungeon, but he was given a second chance at life through an unknown force. He is now able to continuously boost his stats through a special leveling system. At his current level, he can fight A-rank enemies. He is now also capable of defeating several characters from Bleach.
Most of the Bleach characters that Sung Jin-Woo can beat are Soul Reapers or other beings who live within the Soul Society. Most of them wield a special katana called a Zanpakuto, and they many of them can use both Shikai and Bankai. In certain scenarios, Sung Jin-Woo can beat some Captain-level Soul Reapers. He can also beat at least one Quincy, and a few spiritually aware humans.
10 Jidanbo May Be Big, But He Does Not Have A Zanpakuto
Debut Episode: Episode 21: "Enter! The World of the Shinigami"
Jidanbo was the first obstacle that Ichigo and his friends encountered during the Sneak Entry arc. He is the gatekeeper of the Seireitei's West Gate - a position that he has held for over 300 years. Jidanbo may not be an actual Soul Reaper, but he is still considered one of Soul Society's elite members.
Like the other gatekeepers, Jidanbo is a giant, and he possesses immense endurance and physical strength. He also wields a pair of large battle axes. Without a standard Zanpakuto, Jidanbo is basically a huge dungeon boss that Sung Jin-Woo can take down. Even with his endurance, Jidanbo can still be weakened and paralyzed by Sung Jin-Woo's dagger, and Sung Jin-Woo's punches would eventually wear him down.
9 Chad Would Eventually Lose If Sung Jin-Woo Gained Enough Levels
Debut Episode: Episode 2: "The Shinigami's Work"
Chad is one of Ichigo's closest friends. Like other Fullbringers, he can manipulate the souls within physical matter. As a result, Chad can turn his arms into powerful weapons. His right arm can deliver strong punches, but it can also shoot blasts of spiritual energy. It can even block certain attacks with its shield form.
Chad's left arm can deal enough damage to defeat an Arrancar that was once part of the Espada. Chad would have snapped the original Sung Jin-Woo like a twig, but the current Sung Jin-Woo should be able to fight Chad on equal footing. If he continues to level, Sung Jin-Woo's strength will eventually surpass Chad's. That being said, he should still be able to injure Chad with the Kasaka's Venom Fang dagger.
8 Yumichika Would Rather Die Than Use His True Power
Debut Episode: Episode 26: "Formation! The Worst Tag"
Yumichika is now the 3rd Seat of Squad 11, and he is obsessed with beauty. If he uses his Zanpakuto's true name, he can restrain Sung Jin-Woo and drain his life force until he dies. Fortunately, Yumichika only uses this power when others cannot see it. Most of the time, his Zanpakuto takes the form of four evenly spaced sickle-shaped blades. He will use this weakened ability even if it means certain death.
He does this because he fears the rest of his squad will hate his true power. As long as Sung Jin-Woo fights Yumichika in an open space while others are watching, he will be able to beat him with his superior physical strength and dagger. With the dash skill, Sung Jin-Woo should be able to land a few dagger hits.
7 Sung Jin-Woo Can Defeat Tsukishima If He Avoids His Fullbring
Debut Episode: Episode 344: "A Dispute in School?! Ichigo and Uryu, Fight Together!"
Tsukishima is another Fullbringer, and his power comes from his bookmark - which can transform into a katana. It can be used like a standard weapon, but it can apparently cut through anything. If Tsukishima cuts Sung Jin-Woo, he will be able to insert himself into Sung Jin-Woo's memories. In doing so, he can make Sung Jin-Woo believe that that they are actually friends.
Tsukishima can also learn about his abilities. As long as Sung Jin-Woo avoids the katana, he can probably beat Tsukishima in one or two hits. Sung Jin-Woo does not have spiritual energy, so Tsukishima would not be able to sense an attack coming if Sung Jin-Woo uses his Stealth skill.
6 NaNaNa's Shrift Would Have No Effect On Sung Jin-Woo
Debut Episode: Episode 370: "Kill The Shadow"
NaNaNa is one of Yhwach's Sternritter. He does not seem to possess a defensive Blut Vene, which works in Sung Jin-Woo's favor because it means his dagger can cut through NaNaNa's skin. Yhwach gave NaNaNa an ability called The Underbelly, which gives the user the power to identify their opponent's spiritual energy distribution. NaNaNa can find the holes in someone's spiritual energy and expand them until there is nothing left.
His opponent would then be rendered unconscious. The Underbelly is powerful enough to effect someone as powerful as Sosuke Aizen. Fortunately, Sung Jin-Woo's power does not come from spiritual energy, so The Underbelly would not weaken him at all. Sung Jin-Woo would still have to avoid some Quincy arrows, but that should be doable with the Dash skill.
5 Ikkaku Is A Pure Melee Fighter
Debut Episode: Episode 26: "Formation! The Worst Tag"
Ikkaku is the future Lieutenant of Squad 11, and he is a master swordsman who specializes in melee combat. If he releases his Shikai, Ikkaku's Zanpakuto becomes a segmented naginata-type weapon. Sung Jin-Woo can definitely clash with Ikkaku's Shikai, in fact, he should be able to destroy the weapon with his bare hands.
Ikkaku's Bankai is far more dangerous because he gains a large cleaver and monk spade, as well as a large axe head. This Bankai can cut through an Arrancar's Resurreccion like butter. That being said, Sung Jin-Woo can theortically avoid the Bankai with his speed. If Sung Jin-Woo uses Stealth, he should be able to at least nick Ikkaku with his dagger. If this happens, Ikkaku's movements will get slower, and Sung Jin-Woo can capitalize on it.
4 Isane May Become A Captain, But She Is Primarily A Healer
Debut Episode: Episode 45: "Overcome Your Limits!"
Isane was the Lieutenant of Squad 4, but she becomes the Squad's next Captain after Unohana's death. As a highly skilled Kido expert, she can cast multiple high-level spells in quick succession. That being said, Isane mainly specializes in healing Kido, so she is not much of a fighter.
Isane's Shikai is offensive in nature, and she does have a large amount of spiritual energy, but she can be knocked out with a well placed punch. At his current level, Sung Jin-Woo can probably overwhelm Isane with his strength. Given Isane's lack of overall combat experience, she may not be able to block Sung Jin-Woo's Stealth attacks either.
3 Kensei Can Theoretically Be Taken Sown With A Stealth Attack
Debut Episode: Episode 122: "Visored! The Power of the Awakened"
Kensei was reinstated as the Captain of Squad 9 after Aizen's defeat. He can produce explosive air blades with his Shikai. These blades might cause Sung Jin-Woo some trouble, but if he times his movements properly, he should be able to dodge them.
Kensei's Bankai is called Tekken Tachikaze, and it focuses all of his Zanpakuto's explosive power into his fists - which can take the form of knuckle blades or brass knuckles. This Bankai turns Kensei into a pure melee fighter, which means that he needs to get close to his opponent. If Sung Jin-Woo uses Dash at the right moment, he can evade Kensei's punch and then slash him with his dagger. If Sung Jin-Woo does this enough times, his poison dagger will immobilize Kensei.
2 Komamura's Bankai Is Basically A Large Dungeon Boss
Debut Episode: Episode 24: "Assemble! The Gotei 13"
Komamura is part of the Wolfman Clan, and he has been the Captain of Squad 7 since Bleach started. His Bankai produces a massive armored warrior that wields a large blade, and it mimics all of Komamura's movements. To Sung Jin-Woo, this Bankai is basically a huge Dungeon boss, and his dagger should be able to pierce its weak spots.
If Sung Jin-Woo inflicts any critical damage on the warrior, Komamura will sustain the exact same injuries. Sung Jin-Woo can also immobilize the Bankai if he immobilizes Komamura with his dagger. Komamura and his Bankai can temporarily become immortal with the Humanization Technique, but if Sung Jin-Woo evades them for long enough, the technique will end and Komamura will become a significantly weaker wolf.
1 Sung Jin-Woo Can Take Advantage Of Ukitake's Illness
Debut Episode: Episode 40: "The Shinigami whom Ganju Met "
Jushiro Ukitake was one of the first Soul Reapers to graduate from Shin'o Academy - which was founded by Head Captain Yamamoto. He went on to become the Captain of Squad 13. Ukitake has been a Captain for more than a century, and he was one of the strongest Soul Reapers alive during the Quincy invasion. That being said, Ukitake has been dealing with a fatal disease since birth.
Its effects spring up during prolonged battles, and it leaves him in a weakened and compromised state. If Sung Jin-Woo can hold out until Ukitake suffers one of these episodes, he will be able to take him down. It should be noted that the power of Ukitake's Shikai would be useless because Sung Jin-Woo's attacks are not energy based.
