This article contains spoilers from the Solo Leveling manhwa.

Solo Leveling is the new standard when it comes to power fantasy anime series featuring an overpowered main character, Sung Jin-Woo. Fans watched Jin-Woo transform into a powerhouse after two anime seasons, but there’s still room for growth in Solo Leveling Season 3, especially with the upgrades and shadows he will gain.

There’s no stopping Jin-Woo from reaching higher levels in Solo Leveling, and fans are excited. While he reached level 100 last season, he also raised the Ant King’s shadow, Beru, who strengthened his army. With the looming threat of the Monarchs, Jin-Woo needs a new power-up that works like a cheat code, something that will allow him to fight beyond his limits.

Sung Jin-Woo’s True Peak Power Is Still Hidden

Sung Jin-Woo Isn’t at His Absolute Best Yet

Sung Jin-Woo is strong, but he still needs more power.
Sung Jin-Woo needs to grow stronger to protect the world from the Monarchs.

Sung Jin-Woo is still far from his peak form in the anime despite the power he possesses now. While it’s easy to call him the strongest hunter in Korea, equal to the level of national hunters from around the world, his current strength is only the surface of something far greater. He is already overpowered at level 100, but his true evolution has yet to begin, as what lies ahead is not growth through levels but ascension into something godlike.

Manhwa fans know Jin-Woo will continue to grow stronger, reaching a level no hunter or dungeon boss could ever reach. Not even Cha Hae-In, Choi Jong-In, or even Thomas Andre will be able to stand on equal footing with him, as these elite hunters are fated to be sidelined. As much as they like to fight by Jin-Woo's side, they will only hold him back, leaving Jin-Woo no choice but to fight alone and become a one-man army.

Unfortunately, the world forces Jin-Woo to chase more power, whether he likes it or not, making him humanity’s last stand against the Monarchs trying to destroy the world. Without him, mankind would be helpless, so it’s only right for Jin-Woo to inherit a new power-up that will help him face the Monarchs all by himself. This will be Jin-Woo's biggest challenge in Solo Leveling Season 3, unless significant changes are made.

Sung Jin-Woo Will Inherit the Shadow Monarch’s Black Heart

The Black Heart Is a Power-Up that Works Like a Cheat Code

The Black Heart is proof that Jin-Woo is Ashborn's worthy successor.
The Black Heart will give Jin-Woo a near-limitless supply of mana.

Fans are excited to witness the anime debut of the original Shadow Monarch, Ashborn, who has chosen Sung Jin-Woo as his human successor. Of all the Monarchs, Ashborn is one of the most capable, feared for his destructive strength, and respected for his bold attempt to defy even the natural order. By choosing Jin-Woo as his successor, he bestows the Black Heart upon him.

The Black Heart will be a crucial power-up for Jin-Woo, as it holds near-limitless magic energy, unlike anything that Jin-Woo has ever used or experienced before. The Black Heart works like a cheat code, wherein Jin-Woo's mana is constantly replenished, allowing him to summon and sustain shadows indefinitely. This usually drains Jin-Woo, but with the Black Heart, he can maintain his shadow army without breaking a sweat.

Weakness is not something to brag about.—Sung Jin-Woo

Sung Jin-Woo is inching closer to receiving the Black Heart in Solo Leveling Season 3. During the Double Dungeon Arc, where Jin-Woo returns to the Cartenon Temple to learn the truth behind the System and its creator, he comes face to face with the will of Ashborn, eventually inheriting the Shadow Monarch’s Black Heart. This is one of the most hotly anticipated moments next season, a special milestone in Jin-Woo's growth.

Jin-Woo's Black Heart Is Not Just a Power-Up

The Black Heart Is One of the Requirements to Unlock Jin-Woo's Unknown Skill

Solo Leveling Season 3 Will Reveal Sung Jinwoo's New Strongest Ability

One of the biggest mysteries in Solo Leveling is the unknown passive skill Jin-Woo gained after the system chose him as its lone player. This passive skill remains locked in the system no matter how many levels Jin-Woo achieves, hinting that it requires a special condition beyond simple growth.

As revealed in the manhwa, Jin-Woo's Black Heart is one of the requirements to unlock this unknown passive skil l. Without giving too many spoilers, this passive skill is directly connected to Jin-Woo's peak form in Solo Leveling. However, this event might not be covered in Season 3 because the anime is likely to adapt only through the Japan Crisis Arc or the International Guild Conference Arc.
