Sung Jinwoo (성진우) is the main protagonist of Solo Leveling. Originally an infamously weak E-Rank Hunter, he got the chance of a lifetime when he was selected as the Player of the System, giving him the impossibly rare ability to level up in strength beyond any known limits. As a result, by taking advantage of the opportunities offered to him by the System, Jinwoo eventually rose to power as the new Shadow Monarch and the strongest hunter in the world. As the vessel of the Shadow Monarch, Jinwoo is the strongest hunter in the world and completely outclasses even the Rulers' vessels in raw power.
- Immense Physical Prowess: As the vessel of the Shadow Monarch, Jinwoo possesses incomparably immense levels of strength, speed, stamina, and durability. As a testament to this, he was able to crush the Statue of God, beat Thomas Andre to the brink of death while still holding back, kill the Beast Monarch in four hits, and inflict near-fatal injuries on Antares, the strongest Monarch, in their fight.
- Immunity: If Jinwoo is affected by a debuff, this buff automatically removes it from his status, as displayed when it prevented him from being stunned by Baran's lightning breath attack.
- Detoxification: If Jinwoo is poisoned, this buff automatically purges the said poison from his body, as displayed when it was able to almost instantly cleanse him of the Ant King's paralysis poison.
- Tenacity: If Jinwoo's health falls below 30%, this buff reduces all further damage taken by 50% in an attempt to keep him alive.
- Longevity: Jinwoo is immune to all diseases, poisonous substances, and any abnormalities to his status. This buff also grants him a regenerative healing factor, which accelerates exponentially when he sleeps. However, as the System detects alcohol as a poison, Jinwoo can't get drunk.
- Stealth: Jinwoo is able to camouflage with his surroundings and hide all traces of presence, essentially turning himself both physically and magically invisible.
- Bloodlust: Jinwoo is able to magically intimidate a target into submission.
- Quicksilver: Jinwoo is able to increase his speed by 30% for a short burst.
- Mutilation: Jinwoo rips a target to shreds with his daggers. Due to his immense strength, most targets suffer grievous injuries on the first strike.
- Dagger Rush: Jinwoo barrages a target with his daggers from all directions.
- Ruler's Authority: Jinwoo is able to move and control objects via telekinesis. SOURCE:https://solo-leveling.fandom.com/wiki/Sung_Jinwoo
