In the universe of Solo Leveling, some characters are powerful enough to shake the balance of the world. Among them, there is one of the most mysterious and powerful entities in the entire manhwa, and he is Bellion. He is the Grand Marshal of the Shadow Army and the right hand of Ashborn, the Shadow Monarch. This character is overpowered as he is a pure creation of Ashborn’s power, a being brought to life through the authority of death and shadows.
Furthermore, Bellion is given the title of Grand Marshal. It is given only to the highest-ranking member of the shadow army. According to the story, his ranking is currently above Beru, Igris, and Iron, who are formidable forces to reckon with. His origins are not from Earth, as he is from a higher dimension similar to where many Monarchs and Rulers originate.
He is also considered to be the first creation of Ashborn. Therefore, his origin is special, and it is all because his existence is not just powerful, but he is the living blueprint for the rest of the shadow army to follow. As a Grand Marshal, it was his duty to serve as the military commander, advisor, and final line of defense for the Shadow Monarch.

The fact that he appeared in the series is only when the stakes were very high. Bellion is the final trump card of Ashborn when the rest of his army fails. In Solo Leveling, Bellion’s aura is overwhelming. When he first appears on Earth, even Jinwoo’s strongest shadows recognize him as superior.
After Jinwoo inherited Ashborn's full powers as he became the Shadow Monarch, Bellion pledged his loyalty without hesitation, even though he primarily served Ashborn. His act of acceptance is symbolic as it is a moment of validation for the entire journey Jinwoo has taken, and he is now ready to involve himself in the war between Monarchs and Rulers.
While Solo Leveling does not show Bellion active in battle extensively in the manhwa, readers get enough material to understand his terrifying powers. His swordsmanship skills are nothing that has been seen before in the series. Bellion uses his centipede blade in a way that combines speed, power, and unpredictability.
The way he fights, it seems like he was born to be a fighter, and his movements are so precise and fast that they seem to bend the rules of physics. Additionally, his title of Grand Marshal grants him access to the same core powers as the Shadow Monarch. The only thing he cannot do is create shadows like Jinwoo or Ashborn can. Other than that, his skills are on par with theirs.
Interestingly, Bellion’s relationship with Jinwoo in Solo Leveling is not like that of a master to servant. He is more of an advisor and a trusted source to make strategic decisions. In the alternate timeline shown after Jinwoo resets the world to prevent its destruction, Bellion continues to serve faithfully.
What’s next for Bellion in Solo Leveling?

At the end of the story of Solo Leveling, Jinwoo uses the cup of reincarnation to reset the world. He is successful in saving humanity. However, he retains his power and shadows, including Bellion. It means that Bellion is still active but hidden. He, along with Beru and the rest of the shadow army, is on standby in Jinwoo’s shadow, ready to protect Earth from any dangers it might face.
In conclusion, Bellion’s character in Solo Leveling stands out due to his elegance, mystery, and immense power. He does not have enough screen time like Beru and Igris did, but he left a lasting impression. And throughout the story, he never sought recognition. Bellion just fulfills his duty without question.
