Engen The Smiling Man

Regamen.net - If you've been diving into the dark, gritty world of Hero Killer, there's one character who probably sends a chill down your spine every time he shows up: Engen, better known as the Smiling Man. That permanent, carved grin of his isn't just for show—it's a constant reminder of the brutal universe this manhwa thrives in. In a story packed with corrupt heroes, vengeful anti-heroes, and moral gray areas, Engen stands out as this calm, calculating force who feels almost unstoppable.

Hero Killer follows Ihwa, a young woman out for blood after the Hero Clan destroys everything she loves. But while she's the protagonist slicing her way through the system, Engen Hero Killer fans will tell you he's the real scene-stealer. As the leader of the shadowy group called the Nameless (and later New Nera), he's not your typical screaming villain. He's sophisticated, ruthless, and weirdly charismatic. Honestly, in my opinion, he's one of the best villain designs in recent webtoons—right up there with some of the greats in other action series.

In this guide, we're breaking down everything you need to know about Engen: who he really is, how he looks and acts, his heartbreaking yet terrifying backstory, those insane powers, his role in the plot, key relationships (especially that tense dynamic with Ihwa), why fans can't get enough of him, and some light theories on where his story might go. If you're caught up or just starting, stick around—this is spoiler-conscious but detailed. Let's jump in.

Who Is Engen in Hero Killer Manhwa?

At his core, Engen is the deuteragonist of Hero Killer—a major player who sometimes feels like he could steal the whole show. He's the current leader of New Nera, a villain organization aiming to tear down the Hero Clan's dominance. Before that, he headed up the Nameless, a ragtag group of outcasts and powerful fighters.

His most famous alias is "the Smiling Man," earned from that jagged scar stretching across his face like a permanent grin. He's one of the nine Elders—the absolute top-tier Gift users in the world—meaning he's operating on a level most characters can only dream of. Age-wise, he's ancient (centuries old thanks to his Gift), but he looks like a sharp, handsome guy in his prime.

What makes Engen fascinating is how he blurs the hero-villain line. He's undeniably evil—he's killed countless people without blinking—but there's this underlying philosophy driving him. He wants a world where strength rules, free from the hypocritical Hero Clan. Personally, I love how the author portrays him as this elegant monster; he's not chaotic evil, he's purposeful evil.

Engen's m and Personality: Cool on the Outside, Ruthless Within

Visually, Engen is straight-up striking. Tall and well-built, with short light-brown hair, piercing gray eyes, and pale skin that gives him an almost ethereal vibe. He usually rocks sleek dark suits or coats that scream "elegant crime boss." The standout feature, of course, is that massive scar running from ear to ear, forcing his mouth into a constant smile. It's not just cosmetic—it symbolizes everything he's lost and become.

Personality-wise, Engen comes across as calm and collected almost to a fault. He rarely raises his voice, speaks in measured tones, and always seems three steps ahead. But underneath that stoic exterior? Pure ruthlessness. He'll slaughter entire groups if it serves his goals, yet he's oddly honorable with people he respects—keeping promises, mentoring allies, and showing genuine care for his inner circle.

One of my favorite things about him is the subtle charisma. He drops these chilling quotes like "There's only one throne, and I will sit upon it alone" that just ooze confidence. In a sea of hot-headed fighters, his quiet intensity makes him terrifying. If I had to compare, he's like a darker version of some classic anime masterminds—calculated, stylish, and impossible to read.

Engen's Backstory and Origin: From King to Outcast

Engen's past is one of the most epic parts of Hero Killer, packed with wars, betrayals, and massive power shifts. Long ago, he was a follower of the original King of Nera, a legendary figure who united villains under one banner. When the War of Inheritance broke out—a brutal succession battle—Engen came out on top, becoming the second King of Nera.

His reign didn't last peacefully. The Great War (also called the War of the Reeds) pitted Nera against the rising Hero Clan, led by the terrifying Steel Witch. Engen's forces were crushed, and in a humiliating defeat, the Steel Witch carved that infamous smile into his face as a mark of shame. He vanished for years, presumed dead or broken.

But Engen doesn't stay down. He resurfaced quietly, saving a young Rachel Sinclair and building the Nameless from scratch. To reclaim his strength, he climbed the infamous Tower of Milen Kula, achieving a "Breakthrough" that restored his full power. Later, he defeated Reagan Sinclair (Rachel's relative) to claim an Elder seat, and eventually declared the rebirth of Nera as "New Nera."

It's a classic rise-fall-rise arc, but executed with so much grit. The scar origin alone is brutal, and seeing how it fuels his hatred for the Hero Clan adds real depth. In my view, this backstory elevates him from "cool villain" to someone you almost root for—until he does something unforgivable, that is.

Engen's Powers and Abilities: The Terrifying Gift Called "Hell"

Okay, let's talk about what makes Engen truly scary—his abilities. As an Elder, he's got superhuman everything: speed that blurs, strength to shatter buildings, durability that shrugs off insane damage, and centuries of combat experience. He's a master swordsman with his signature blade Reconquista, and his tactical brain turns fights into chess games.

His core Gift is "Hell," a darkness manipulation power that's downright nightmarish. He can solidify shadows into weapons, creatures, or massive armies. The Gift draws from Buddhist hell realms, with sub-techniques named after them:

• Sañjīva: Basic darkness constructs—tentacles, blades, shields. Versatile and fast.
• Kalasutra: Black lines that slice through anything, even other Gifts.
• Pratāpana: Massive heat waves or explosions from concentrated darkness.
• Avīci: His ultimate form—a colossal darkness monster that overwhelms entire battlefields.
• Plus teleportation through shadows, summoning hordes of shadow beasts, and even flight in some forms.

Pre-Breakthrough, daylight weakened him significantly, but now? He's near full power anytime. Weaknesses are few—bright light still hampers him a bit, and overwhelming force can push him back—but good luck landing that.

Fights with Engen feel epic because he's so creative with Hell. Watching him summon an army of darkness creatures or turn the battlefield into a void is pure visual spectacle. No exaggeration, his power set is one of the coolest in the manhwa.

Engen's Role in the Hero Killer Story

Engen isn't just background—he drives major arcs. From the District 17 assault to the Torch storyline, Castle Gray siege, and the ongoing War of Disbandment, he's the puppet master pulling strings against the Hero Clan.

He uses Ihwa as a weapon of chaos while subtly guiding her growth, all to weaken the Elders and heroes. As of early 2026 (around Episode 246 on Webtoon), the conflicts are heating up with massive battles involving multiple Elders. Engen's goals remain centered on rebuilding a world ruled by true strength.

His presence keeps the stakes sky-high. Every time he steps in, you know things are about to go sideways.

Key Relationships: The Complicated Bond with Ihwa

The standout dynamic is Engen and Ihwa. He saved her on a whim (at the request of someone from her past), trained her briefly, and now treats her like a useful tool/rival. Their fights are legendary—raw power vs. adaptive fury—and there's this weird mentor-student tension underneath the violence.

Other ties: Rachel Sinclair as his loyal protégé, Vector as a former right-hand man, and bitter rivalries with heroes like Reagan Sinclair (whom he defeated). These relationships humanize him just enough to make you question if there's any redemption possible.

Honestly, the push-pull with Ihwa is my favorite part of the series. It's never simple hatred—there's respect, manipulation, and genuine intrigue.

Why Engen Is a Fan-Favorite Villain

Fans adore Engen because he's the perfect "love-to-hate" character. Ruthless? Yes. Boring? Never. His design, voice (in your head), quotes, and sheer presence make him memorable. Reddit and TikTok are full of edits praising his depth in a morally gray story.

In a genre crowded with one-note bad guys, Engen feels real—driven by pain, ambition, and ideology. That's why he tops so many "best villain" lists for Hero Killer readers.

Fan Theories and Latest Updates

Theories swirl around Engen's endgame: Will he clash decisively with Ihwa? What's his true connection to the Torch? Could there be any redemption, or is he destined for a tragic fall? As of January 2026, the manhwa is deep into high-stakes Elder battles, with Engen right in the center.

If you're not caught up, head over to the official Webtoon page and binge—it's worth it.
