Over the last decade, anime has heralded the rise of the overpowered anime protagonist -- a character who is too strong to fit the standards of their world, whose power makes it all but impossible for them to lose. While One-Punch Man's Saitama is the most well-known example, he is far from the only one. Koro-sensei in Assassination Classroom is an alien-looking, once-human entity who intends on destroying the Earth, that is, after teaching a classroom of students who all want to kill him.
In contrast, Lloyd from the anime and light novel series Suppose a Kid from the Last Dungeon Boonies Moved to a Starter Town is an adventurer from a legendary village full of the strongest people in the universe who come to a town filled with ordinary people. Both are compelling characters with insurmountable strength. However, which one is truly stronger? By analyzing the peaks of their power, it becomes clear which one would win in a battle.
How Powerful is Lloyd?
Even given Lloyd's demonstrations of power thus far, it's hard to determine just how absurdly strong he is and how high his limits go. He can run across a continent in six days -- though his grandfather can cross it in two. Anything short of a demon lord is a mild inconvenience to Lloyd. Even with his ultimate strength masked with uncertainty, we know he can throw several ton monsters through the air like they're feathers.
Furthermore, Lloyd has knowledge of several runes that enhance his abilities even further. One such rune that he uses on a handkerchief can deactivate the Cursed Belt Princess Selen's cursed belts that had bound her face for years. His understanding of runes is so advanced that even so-called magic experts in the village he travels to confuse the ancient runes for scribbles rather than artifacts.
Lloyd is simply great at everything, but he is so naive about it that he has no idea. He almost kills a man in one punch during a sparring fight, unaware of his incredible strength. After breaking every bone in his body, he recovers in a matter of hours rather than in several months. Even demon lords, entities who can capably eradicate whole planets, Lloyd sees as manageable threats.
Still, due to the comedic nature of Suppose a Kid from the Last Dungeon Boonies Moved to a Starter Town, Lloyd has yet to be pushed to his absolute limits, indicating that there is a vast well of untapped power.
How Powerful is Koro-Sensei?
Due to Assassination Classroom being a completed shonen manga, the limits of Koro-sensei's power have been explored. Koro-sensei was once a human but was subjected to a series of grotesque antimatter experimentations until he was transmuted into a tentacled, alien-looking creature. This results in him being a monstrous entity capable of incredible power. He has several abilities that emerge throughout the series, some of them being quite unusual and impractical in his battle against Lloyd.
Due to Koro-sensei's unique physiology, almost all weapons are ineffective against him. Save for anti-sensei weapons -- created from a specialized material to be effective against Koro-sensei -- all traditional items are useless. Koro-sensei can regenerate from nearly any injury and sense anything around him, reacting with super-speed in response. Plus, he can generate powerful laser blasts that can eradicate whatever they touch, not to mention he can liquefy and reassemble himself. He is so fast he can create multiple afterimages of himself, all of which can teach his various students.
One of his most significant abilities is his Absolute Defense Form. He compresses into a singular point, creating an impenetrable defense that nothing -- save for maybe the Spear of Heaven satellite laser -- can break. Of course, there is also Koro-sensei's claimed famous deed of destroying a large chunk of the moon.
If Lloyd and Kuro-sensei Fought, Who Would Win?
Determining who would emerge on top in a fight between Koro-sensei and Lloyd is reasonably tricky. While Koro-sensei is powerful and can probably react to anything Lloyd threw at him, Lloyd is also far too strong to be hurt by him. Or, at least, seemingly. The factor that might tip the scales in Koro-sensei's favor is that he is an extraordinarily talented and experienced assassin and fighter, which allows him to know how to break a target apart. By contrast, most of Lloyd's success is by accident. It is due to Lloyd's inexperience that he doesn't understand how vastly overpowered he is.
However, while Koro-sensei's experience gives the advantage of fighting and killing abilities, Lloyd might have an edge with his vast knowledge of runes. While none of Lloyd's weapons are anti-sensei matter, he might be able to break the core of Koro-sensei's abilities using any number of his reality-altering runes. If Lloyd could negate Koro-sensei's antimatter, that may leave him in his human form.
Still, all of this requires Lloyd to attack Koro-sensei and break his power level knowingly, and it's necessary to remember that Lloyd has a tendency to solve all problems by accident. Factoring in his absurd luck, Lloyd could unintentionally select the right rune to negate Koro-sensei's abilities.
However, barring the possibility that Lloyd breaks the core of Koro-sensei's power, it's unlikely that he'd defeat the antimatter being. Unless Lloyd uses magic to damage Koro-sensei's specific physiology, it seems as though Koro-sensei might emerge the victor in the battle -- though it's unlikely Koro-sensei has anything in his power set to kill Lloyd either. While Lloyd may find the right rune to reduce his opponent back into a human assassin, it looks like Koro-sensei takes the win.
