I also think Beru is quite memorable. He is a loyal and powerful servant to Sung Jin - woo. His unique abilities and his relationship with the protagonist make him stand out. And then there is Cha Hae - in. She is an important female character, strong - willed and a great support to the main character at times, which makes her a memorable part of the story.
Sung Jin - woo is obviously the most popular. He's the main character of Solo Leveling, and fans love to write about his further adventures, power - ups, and his relationships with other characters. Cha Hae - in is also quite popular. Many fanfictions explore her relationship with Jin - woo in more depth, whether it's a romantic relationship or just a strong friendship. Another popular character is Woo Jin - chul. Writers often use him to add some comic relief or to show the human side of the hunter world through his perspective.
The antagonists in the side stories can also be quite memorable. They might have different motives and powers from the main antagonists in the main story. Their actions and decisions can create a lot of tension and drama in the side stories.
The protagonist is definitely one of the most interesting characters. His growth from a weak hunter to a powerful one is captivating. Also, some of the villainous characters are quite intriguing. Their motives and the way they try to oppose the protagonist add a lot of depth to the story.
Percy Jackson himself is likely to be very popular. Since it's a Percy Jackson - centered fanfiction, readers are drawn to his character. His unique powers and his journey of growth are always interesting to follow, especially when combined with the elements from Solo Leveling.
I think the side characters who assist or oppose the main character can be really interesting. They add depth to the story. For example, those who have their own motives and powers that interact with the main character's. In 'solo leveling vol 6 graphic novel', they might be characters who are introduced to help the main character in a new way or those who try to stop his progress for their own reasons.
Lucy might be popular too. Her celestial spirit magic can be explored in new ways in this fanfiction. She could potentially summon spirits to help her level up faster or gain special abilities from them as she progresses through levels.
For me, the most exciting part is when the protagonist starts to rapidly level up. It's so thrilling to see his power increase and how he overcomes the seemingly impossible challenges.
