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.
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.
Definitely Jinwoo. He has all these cool powers like summoning shadow soldiers and has reached high levels in his leveling journey. Goto doesn't have such powerful capabilities as Jinwoo.
One interesting aspect is the character development. In these fanfictions, characters can take on new roles based on their levels. For example, Naruto might be a low - level beginner at first and have to work his way up. This gives a different perspective on his character. Also, the crossovers can introduce new relationships and rivalries. Like a character from Solo Leveling could become a rival to Sasuke, which adds a whole new dynamic to the story. It also allows for exploring different plotlines that weren't possible in the original Naruto series. The fanfiction can expand on the world - building of Naruto by adding elements from Solo Leveling, such as different types of dungeons or quests within the Naruto world.
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 battles are really exciting. For example, when the main character faces powerful monsters, his strategic use of his skills and quick thinking make the fight scenes intense. Also, the moments when he levels up and discovers new powers are great.
For me, the most exciting part is when the protagonist overcomes seemingly impossible challenges. His growth from a weak hunter to a powerful one is really thrilling.
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.
