Alien Invasion: When a gate first opens, only humans can pass through, but if the dungeon inside isn't cleared within a week, the monsters inside will be able to use the gate to invade the human world. And all of them are compelled to Kill All Humans. Spell My Name With An S: Due to the many ways Korean can be romanized and translated, this is to be expected. Foil: Yoo Jin-ho is basically one to Lee Min-sung. Both are rich people, whose fathers are the leaders of one of Korea's most powerful companies, Yoojin Construction. However, Jin-ho, while relatively weak as a hunter at D-rank, is kind, generous and willing to put his life on the line for a teammate, while Min-sung is a Manipulative Bastard, an Attention Whore and a pathetic Dirty Coward despite being a powerful A-rank Hunter.

Retirony: Min Byung-goo only came out of retirement to complete the Jeju Raid and then was planning on quitting permanently. He becomes the only Korean Hunter to get killed. Super-Reflexes: Hunters who focus on agility have great reflexes. Since Jin-woo used a lot of his stat points on agility, he also has superhuman reflexes.Kang Tae-shik is fabricating extremely obvious lies, to explain how everyone but him supposedly will die inside the dungeon. First, he tries to Make It Look Like an Accident, but changes the story and intends to frame the criminals, who are forced to clear the dungeons. In both the novel and the webcomic, he offers to spare Jin-woo, Ju-hee and Chi-yeol if they keep their mouths shut about what they saw, but Jin-woo immediately points out that this lie isn't very convincing when he already attempted to kill them just moments earlier. And I Must Scream: Those who arise involuntarily as Jin-woo's shadow minions are bent to his will. Thus, Kim Cheol received a Fate Worse than Death. Shortly after entering his first instant dungeon, unlike inside regular dungeons, Jin-woo realizes that the monsters respawn. He uses this opportunity to level up for several hours before facing the dungeon's boss. Eventually, the System rewards his perseverance with the title "Wolf Slayer", which comes with a significant stat boost when he's fighting beast-type monsters.

Degraded Boss: Many powerful monsters that might be found as Bosses can be found acting as the front-line troops for higher ranked Gates, almost always resulting in an Oh, Crap! moment for the Hunters. Not even Kamish, the most powerful monster previously encountered by humanity, is exempt from this; at least three similar dragons can be seen among the Shadows accompanying Bellion when the remaining members of the original Shadow Monarch's army arrive in Korea. Named After Somebody Famous: Jin-woo names his ant king shadow soldier "Beru", after Bernard Werber, who wrote a famous book series about ants. Go Out with a Smile: After Min Byung-goo's shadow saved Cha Hae-in's life at the end of the ant extermination operation on Jeju Island, Jin-woo lets his soul rest and releases Min Byung-goo, who with a smile on his face vanishes into nothingness. On February 2, 2022 , Solo Leveling is receiving its video game version and would be an action RPG title for PC and Mobile. On April 10,2023 , Solo Leveling received a spin-off doubling as a sequel called Solo Leveling Ragnarok following Sung Su-Ho. Gaining the Will to Kill: Subverted, because it's actually forced onto Jin-woo. When his life is threatened by another hunter, the system makes him fight to the death, or else his heart will stop and he dies regardless.Morality Adjustment: Jin-woo is still a good person, but as he levels up as a hunter, he becomes colder and more of an Anti-Hero. After killing Kang Tae-shik, Jin-woo sees that the boss room was full of hobgoblins and a powerful boss... for a D-rank dungeon that is. He notes that this likely would have caught hunters off-guard, because earlier they only had to fight against normal goblins, who didn't engage in large numbers.

(except for some documents and illustrations where licenses are specified) Don't You Dare Pity Me!: Jin-woo has told no one why he keeps working as a hunter (to provide for his hospitalized mother and underage sister), despite being so weak and the job constantly threatening his life. He doesn't like revealing personal information to others, and it's implied that he doesn't want to be pitied even more than he already is for being the "World's Weakest Hunter". A-rank boss, Kargargan, uses one of his minions to speak to the Hunters raid force, demanding from them to come to him.
