2026 Edition

11 Novels

Genius protagonists in Korean action combine intelligence with combat capability. They don't just fight stronger, they fight smarter. Strategic use of skills, manipulation of enemies, and exploitation of system mechanics distinguish them from straightforward power fantasy leads.

The genius element often comes from regression, giving protagonists future knowledge, or from unique analytical abilities that let them see patterns others miss. The action becomes more interesting when there's planning behind the punches rather than just increasing stat numbers.

TOP PICK
Dungeon Defense
4.5
(3.0K ratings)
Genre: action, drama, ecchi
Do you know how this world ends? Become the hero and defeat the 72 Demon Lords.
First Impressions
Dungeon Defense is a web novel that certainly sparked a lot of strong opinions, and after diving in, I can see why. It's a story about a protagonist who transmigrates into a game he's beaten, becoming the weakest demon lord, Dantalian. He has to use his wits and cunning to survive and rise in a world filled with scheming nobles and powerful enemies. Initially, I was hooked by the premise. The idea of an intelligent, manipulative main character in a fantasy setting is always appealing. The first volume seemed to set up a fascinating world of political intrigue and strategic battles, and I found...

Ending Maker
4.5
(991 ratings)
Genre: action, adventure, comedy
Two heroes of the game Legend of Heroes 2 who were rotten waters*. Kang Jin-ho in the first place and Hong Yoo Hee in the second place.
First Impressions
"Ending Maker" promised a fun ride through a familiar yet twisted reincarnation story, and for the most part, it delivered. It's a story where two gamers find themselves inside the world of their favorite game, armed with meta-knowledge and a chance to avert a looming apocalypse. Right off the bat, I was drawn in by the dynamic between Jude and Cordelia. The initial chapters are filled with quirky banter and humorous situations as they navigate their new reality. Their relationship starts off as a rivalry friendship, and watching them plan, support each other, and grow together is genuinely en...

If You Don’t Become the Main Character, You’ll Die
4.8
(282 ratings)
Genre: action, adventure, comedy
I suddenly found myself dropped into a fantasy kingdom story. But what’s the status of my scenario importance?
First Impressions
"If You Don’t Become the Main Character, You’ll Die" is a wild ride that I'm so glad I decided to jump on. With a near-perfect rating and a sprawling storyline, I was intrigued, and after diving in, I can definitely see why it's so beloved. It's a unique blend of genres, and the execution is what really makes it shine. Initially, the title and summary made me think this would be another run-of-the-mill transmigration story. You know, the kind where the protagonist just clings to the main character for survival. But boy, was I wrong! From the get-go, the author throws you into a world brimming ...

Everyone Else is a Returnee
4.3
(3.5K ratings)
Genre: action, adventure, comedy
Yu Ilhan was always the one left behind. Left out of cliques in school.
First Impressions
"Everyone Else is a Returnee" is a web novel that I dove into with a mix of excitement and trepidation, given its high overall rating and diverse range of reader opinions. It’s a story about a protagonist left behind on Earth while everyone else is transported to another world to train for a coming apocalypse. The premise is intriguing and promises a unique take on familiar tropes, but does it deliver? Here's my take. Initially, I was hooked by the concept. A loner, overlooked by the divine, gains immense power through sheer dedication and hard work. It's a classic underdog story with a twist....

Sovereign of Judgment
4.2
(839 ratings)
Genre: action, adventure, fantasy
A fighting genius. In grade 6, Choi Hyuk killed someone.
First Impressions
"Sovereign of Judgment" is a web novel that grabbed my attention with its blend of action, adventure, and a dash of sci-fi elements. It's a story about survival, revenge, and the lengths one will go to achieve their goals. While it has its flaws, the overall experience has been a thrilling ride. The initial chapters threw me into a brutal survival game where the protagonist, Choi Hyuk, a suppressed fighting genius, is forced to unleash his true potential. I was immediately hooked by the premise and the fast-paced introduction. It felt like a battle royale with a martial arts twist....

#6 PICK
The Regressed Demon Lord is Kind
4.3
(703 ratings)
Genre: action, adventure, comedy
My whole life, all I wanted was power. I churned the world into rivers of blood and eventually gained the title, ‘Demon Lord of Strength’.
First Impressions
"The Regressed Demon Lord is Kind" is a web novel that certainly took me for a ride. Going in, I wasn't quite sure what to expect, but I came away with a generally positive impression, though not without a few reservations. Initially, the premise felt somewhat familiar: a regressed protagonist aiming to live a kinder life. However, it quickly became apparent that the author was playing with expectations. The "kindness" in the title should probably be in quotes, as the main character, Zich, has a rather... unique interpretation of the concept. It’s more about beating up bad guys in the name of ...
