I'd recommend 'Solo Leveling'. It has a protagonist who grows powerful and faces various challenges, similar to the themes in Hero Killer. Also, the art is amazing. The story progression keeps you engaged throughout.
Well, 'The God of High School' has a similar action-packed style and intense battles like Hero Killer.
In 'The Hero Killer' manhwa, the main character is driven by a sense of justice and embarks on a dangerous mission to expose and eliminate false heroes. The story has complex characters and a captivating narrative that explores themes of morality and power.
The appeal lies in its complex storylines and well-developed character arcs. The art style is also often visually stunning, adding to the overall enjoyment. Plus, it offers a fresh take on common superhero themes.
It's likely a type of adult-oriented and potentially violent or controversial manhwa content. But be cautious, as such themes might not be suitable for all audiences.
There were novels similar to Marvel's Hero Killer: 1."The richest man on Earth starts from the primitive wilderness." Author: Happy Popcorn 2.

Author: Super Erha The following is a detailed introduction of these novels: 1."The Richest Man on Earth Begins in the Primitive Wilderness": War is terrible. It can destroy everything. If human civilization were to disappear and return to the era of drilling wood to make fire, gathering and hunting for a living, would you still be able to survive? Entering the wilderness, our global competition has begun! They ventured deep into the Amazon rainforest, survived the storm on rafts, and escaped from the death strangulation of giant pythons... They would go back to the place where Su Wu was herding sheep, feel the cold wind of-50 degrees Celsius in Siberia, and fight with the wild wolves that were rushing towards them... The canoe sailed across the ocean, and not only did it face the surging waves, but when you wanted to eat fish, the great white shark opened its bloody mouth and bit you… "What happened to the animals that tried to bite you?" asked the reporter. Lin Zheng: "The protein has turned into an amine acid, and it has injected…powerful energy into my body!" The story had to start from the North American continent, hunting, gathering, fishing, catching turkeys, smelting copper, forging iron, and making porcelain… In 30 days, they had embarked on a path of civilization that the Native Americans had never taken in tens of thousands of years. At first, every step was frightening. There were so many snakes in the valley! 2."The Moon-Shaped Magician in the World of Beauty and Manga": When the Mirror Realm, the reflection of the world where humans usually lived, was wreaking havoc in various universes, Gem Weng pulled Paracelsus down from Heroic Spirit, folded it, and threw it into the Multiverse that had been harmed by the Heroic Spirit. Superman/Batman/Captain America/Iron Man/Green Lantern: "You're here to save our universe, right?" Paracelsus smiled and said nothing. "Right…right?" The great magician Paracelsus, who was kind, rational, steady, and did not like to fight, shook his head. "I just want to drain the magic power of your world and send it back to our world." "This way, we don't have to worry about the Originator drying up!!" 3:"Fairy, I've Changed Your Character Setting":"Fairy, I've Changed Your Character Setting." "It's true.“ 4:"I Play as a PC Hero at Marvel": Abandoned Book Chapter 115 The story was interesting and the plot was compact. It was a story about crossing the Marvel World with a DC-based system. There were many characters in the middle, such as Brotherhood and Ninja Turtles. The main reason for abandoning the book was that the protagonist had a serious problem with his three views. In order to show off, he could ignore human lives. In order to accumulate points, he could watch tragedies happen. If the protagonist had a problem with his values, he could continue reading. After all, the character could be cold-blooded. However, after more than 100 chapters, he realized that it was the author's problem with his values. Removing the crisis in advance will not give you any Justice Points. Instead, you will have to wait until the crisis appears before you can get any Justice Points. Moreover, the greater the damage caused by the crisis, the more Justice Points you will get. I was shocked and quickly exited the game. 5."From Absolutes to Cosmic Sword Heroes"(Goldfinger skill is a skill from Dungeon Fighter Online and Elden Ring of Magic.

Look at my bragging roar + the determination of a Royal Knight + rage explosion + the soul of the sword + an ordinary sword swing. The main skill is to fly with bricks. Max had a cosmic sword that could pierce through the galaxy? Watch me stack buffs and charge up three times, Majestic Kalia, piercing through the Multiverse with a single sword. Ultraman's unique idealistic explosion? He wanted to understand the principle of the regressiveness of eliminating everyone's buff within the range. Falling Light Blade, Collapsing Mountain, Earth Wave Sword, Soul-Devouring Demon Sealing Slash… Lion Slash, Moon Shadow in the Cracks, Mountain of Corpses and Sea of Blood, Queen of Black Flames, Waterbird Dance… When Hermes combined all the sword skills in the game, the most powerful sword master in the history of the universe was born. What was that? The planet is about to explode, but our friendly neighbor, the Country of Light, won't give the planet to us, the great Absolutes? Hermes said,"It doesn't matter.

He was the only one in the world!
Another one could be 'Tokyo Ghoul'. It has a darker tone but shares elements of power dynamics and complex characters like in Hero Killer.
I'm not sure exactly, but it could be about a hero facing off against a powerful villain who's known for killing heroes.
The manhwa 'Hero Killer' is remarkable for several reasons. Firstly, the world-building is incredibly detailed and immersive. Secondly, the villains are not just one-dimensional but have depth and motivations. And the pacing is just right, never feeling rushed or dragging on.
I'm not really sure. Maybe it's a manhwa about a hero killer in the world of Olympus, but that's just a guess.
You might like 'Tower of God'. Both have complex characters and a captivating plotline that keeps you engaged, similar to what you find in Killer Peter.
There are a few options. 'The Gamer' has a similar action-packed style and complex characters.
