While there's still a lot left to be covered in the Solo Leveling Season 3, there's no doubt that Jinwoo is shaping up to become one of the most powerful anime characters. As a result, as he keeps leveling up, fewer characters within Solo Leveling's universe might be stronger than Jinwoo or capable of defeating him. However, things change when adding other anime franchises into the equation since, even though the reason why Jinwoo can keep raising his stats is because there is no current limit to his powers, he is not invincible.

So, beyond the fact that manhwa fans may already know that Jinwoo is one of the strongest fictional beings that exist, there are still many other characters from other anime and manga franchises who could defeat the Shadow Monarch. Across the medium, certain anime characters have great advantages against Jinwoo, and whether due to their innate abilities or excessive plot armor, they could beat him or at least give him a tough battle.

8 Misogi Kumagawa

Medaka Box

A character who, unfortunately, had little screen time after the cancellation of the Medaka Box anime is the antagonist, Misogi Kumagawa, who didn't get to show how much of a powerful Minus he was in the series. However, what anime fans got to see in the last episode of Medaka Box Abnormal is enough to place Kumagawa among the strongest characters in the medium thanks to his overpowered ability, All Fiction. Just as its name suggests, Kumagawa's power can turn anything he wants into "fiction" or nothing.

This is because Kumagawa remodeled the original functioning of All Fiction from reversing the cause-effect of anything to nullifying even causality itself and denying reality. As a result, Kumagawa is capable of erasing injuries, people, concepts, and even the world if he desires to. Due to how All Fiction works, Kumagawa is a bad match for Jinwoo. Kumagawa can erase from Jinwoo's daggers all the way to his whole shadow army, the level-up system, and even mana, leaving the Shadow Monarch unable to counter him. Even if Jinwoo wins with his brute force, Kumagawa can easily heal himself.

7 Reinhard Van Astrea

Re:Zero

Reinhard Von Astrea isn't Re:Zero's protagonist but is a great example of how an unreasonably powerful ability can beat raw strength. Reinhard grows up as a threat in Re:Zero's universe after being born with the divine protection of the world known as Phoenix Blessing. This blessing gives Reinhard unique and completely unrestrained luck and protection, giving him all kinds of powers to ensure his survival. In other words, the Phoenix Blessing made Reinhard immortal, as even if he supposedly can only come back from death once, there's no real limit to the times he can wish for this blessing.

Furthermore, Reinhard van Astrea's power doesn't stop at just being basically immortal but has an insane range that challenges what's reasonable with absurd abilities like avoiding rain from touching him, getting a power-up on sunny or rainy days, mastering weapons, and even differentiating salt from sugar. So even if Reinhard's sword skills may not be enough to defeat Jinwoo right away, he can always obtain a new blessing until finding one capable of defeating the Shadow Monarch.

6 Rimuru Tempest

That Time I Got Reincarnated as a Slime

Rimuru Tempest is easily one of the strongest isekai anime characters despite being reborn as a simple slime, who was believed to be the weakest monster in his new world. This is thanks to his unique ability, Gluttony, which allows him to prey on the abilities of others and steal them for himself, in addition to having a great way of upgrading his combat skills, since he can transform into anything he consumes.

These power-ups don't extend to only physical upgrades, but Rimuru can also use them to improve intellectually with abilities like Mind Accelerate, with which he can create multiple strategies to end up as the victor in any battle. In a way, his possibility of getting stronger without limits by adding powerful skills is similar to Jinwoo. However, Rimuru may have had a bit of a head start and, after becoming a True Demon Lord, this list of his powers just keeps increasing, becoming unbeatable thanks to abilities like ultraspeed Regeneration, Space-Time Domination, and God's wrath.

5 Yhwach

Bleach

Yhwach, the main villain of Bleach: Thousand-Year Blood War is known as the Father of All Quincy and is without a doubt one of the strongest characters in the whole franchise who could face even Aizen. Yhwach's power is immeasurable, being sealed for almost 1000 years due to his objective of destroying the Soul Society and Soul King. Among his abilities, Yhwach can grant power to others, distributing parts of his soul and later stealing it back once it has been cultivated.

However, Yhwach's most fearsome power is The Almighty, which allows him to foresee any future timeline (even those where he dies) which, along with his high intellect, allows him to alter it to his benefit and act according to every threat in his way. The Almighty not only makes him one of the strongest characters in Bleach but also makes it impossible for Jinwoo to defeat Yhwach, as he can change the future to one where he ultimately wins. Because of this, the only way to fight Yhwach is futile unless his ability can be stopped.

4 Yogiri Takatou

My Instant Death Ability Is So Overpowered, No One in This Other World Stands a Chance Against Me!

Yogiri Takatou shows from the title of his anime that he is a character created to be indestructible. This is seen by the fact that Yogiri’s ability, Instant Death, allows him to kill anyone with a simple thought. However, this skill is more versatile than it sounds like as it goes beyond only killing things that he can see, which would leave him open to surprise attacks. Yogiri can also sense any murderous intent and hostility at him or his allies. This way, Yogiri can predict the movements and patterns of their enemies, track them, and kill them easily.

Still, even if nothing is faster than the thought, Yogiri's ability is also triggered automatically when something threatens his life imminently. So Instant Death can kill practically anything, even immortal beings, and concepts, working as a perfect plot armor leaving Jinwoo with no possible way to engage in a battle and win.

3 Anos Voldigoad

The Misfit of Demon King Academy

The protagonist of The Misfit of Demon King Academy, Anos Voldigoad, was born with unlimited destructive power and has undeniable skills. After 2000 years of his death, he was reincarnated and proved on several occasions to be a step above any other demon, especially after defeating one using the beat of his heart. Even Anos' speed is remarkable, being faster than Gazel Apt Ageila, who reached the speed of light.

Furthermore, Anos is a brilliant magic , mastering many types of attacks and being especially proficient in destructive magic. Additionally, it has been claimed in the series that Anos could destroy a universe with his fists. Also, given that Ano could also grab Sasha's castle with one hand, it is unlikely that Jinwoo can win in a physical fight. As a powerful demon lord, Anos Voldigoad has proven to be able to come back to life, so the only option to defeat him would be to erase him from existence.

2 Saitama

One-Punch Man

Saitama is certainly a unique type of hero and one who doesn't struggle with any fight after breaking his limiter in One-Punch Man. Saitama fought without breaking a sweat with a planet destroyer like Boros who could launch powerful energy blasts, and he could wipe out strong monsters and even asteroids with only his bare punch. Also, along with his super strength, Saitama can move at an incredible speed, which makes it difficult for Jinwoo even the chance of moving quickly enough to land a hit on the hero by surprise or even avoid a punch from him.

Ultimately, as a gag character, Saitama’s powers have virtually no limits. Because of this, it doesn't matter how strong Jinwoo gets or how much he levels up, since Saitama's biggest character trait is to defeat anyone with a single blow. This makes Caped Baldy always win in the end. Still, even if Saitama has the advantage if the two characters face each other, Jinwoo will be one of those few characters that can actually make the hero get serious.

1 Zeno

Dragon Ball

So far in Dragon Ball's story, there's no hint that a living being is capable of harming Zeno. Although it has been hinted that the Great Priest is a better fighter, as Zeno himself doesn't fight, the latter is still on a different level than any other character in Akira Toriyama's franchise, as the Omni-King and ruler of the multiverse who can make everything disappear with one finger being a person, a galaxy or universe as seen in Dragon Ball Super. Furthermore, it has been stated how they were originally eighteen universes until Zeno reduced them to twelve one day.

This is why Zeno holds the most power out of anyone in all of Dragon Ball and characters that are currently stronger than Goku, like Beerus, Whis, and other Gods of Destructions, respect him, with some even being afraid of him. It doesn't seem likely that Jinwoo can win in any way, as Zeno's abilities range from existential erasure, space manipulation, longevity to existence along with the multiverse, and probably many more invincible skills that escape from finite understanding.
