Monsters in the Hero Association’s most dangerous enemy faction are usually known for their terrifying strength and destruction. However, not all of them strike fear into the hearts of their opponents. Some members of the Monster Association are more ridiculous than intimidating.
They bring comic relief even in the middle of serious battles. Whether through their ridiculous designs, exaggerated personalities, or embarrassing defeats, these monsters stand out for reasons other than raw power.

While some are aware of how foolish they appear, others take themselves too seriously, which makes their failures even funnier. Their presence adds a layer of humor to the story, balancing out the intense fights and high-stakes battles.
Here are some of the funniest monsters ranked based on their ridiculousness, dialogue, and entertainment value.
1. Phoenix Man
Phoenix Man is one of the strangest characters to emerge from the Monster Association. At first glance, he seems like an ordinary villain with a bird-like appearance, but his real comedy comes from his exaggerated personality and absurd ability to resurrect himself.
His dramatic speeches make him look like an important and powerful figure, but the reality is quite different. His transformations may appear intimidating, but they are often met with unexpected defeats, making his so-called “immortality” more of a running joke than a real advantage.
His reliance on theatrics, combined with his exaggerated confidence, makes his interactions with opponents hilarious. Even when he tries to act serious, his ridiculous design and attitude make it difficult to take him seriously.
2. Gums
Gums is a perfect example of a monster that is more laughable than terrifying. With his enormous, blob-like body and the ability to consume almost anything, he looks like a parody of a childhood nightmare. His entire existence revolves around eating, and his one-track mind makes him unintentionally amusing.
While he has impressive strength, his design and behavior make it hard to see him as a real threat. His interactions with other monsters also add to the humor, as he rarely speaks and mostly focuses on stuffing his face.
Watching a creature of his size and supposed strength behave like a mindless eating machine instead of a fearsome warrior adds a layer of absurdity to his character.
3. Royal Ripper
Royal Ripper is a strange combination of terrifying and hilarious. His appearance is designed to be scary, but his over-the-top personality and love for theatrics make him more ridiculous than fearsome. He acts like a psychotic villain straight out of a horror movie, but his behavior is so exaggerated that it becomes comedic.
His high-pitched laughter and dramatic way of speaking turn even serious moments into something amusing. While he enjoys torturing his victims, his enthusiasm often comes across as childish rather than menacing. This mix of horror and comedy makes him one of the funniest members of the Monster Association.
4. Black Sperm
Black Sperm stands out as one of the strongest characters in the Monster Association. His entire ability revolves around splitting himself into smaller versions, making it difficult to take him seriously.
The way he constantly boasts about his strength while behaving like an overgrown child makes him one of the funniest characters in the series. His arrogance and constant taunting make it satisfying when he is eventually put in his place.
Even when he reaches his final form, his behavior remains so exaggerated that it is difficult to see him as a real threat. His interactions with other characters, particularly his rivalry with flashy heroes, make him a consistent source of comedy.
5. Bug God
Bug God is supposed to be a tough and durable monster, but his design and personality make him unintentionally funny. With a name like “Bug God,” one would expect something terrifying, but he looks more like a rejected cartoon villain than a true threat.
His dialogue is filled with self-important declarations, yet he rarely lives up to his hype. His tough-guy attitude only makes his eventual defeats more amusing. The contrast between his supposed strength and his actual performance in battles makes him one of the more entertaining monsters in the series.
6. Do-S
Do-S is one of the more unique monsters in the Association, but her entire gimmick revolves around a dominatrix-like appearance and behavior. While she is designed to be seductive and manipulative, her exaggerated mannerisms make her more ridiculous than threatening.
Her way of speaking and her dramatic movements often make her seem like she belongs in a completely different genre. Despite her powers, she does not last long in battle, and her defeat is just as dramatic as her introduction. The fact that she takes herself so seriously only adds to the comedy of her character.
7. Vaccine Man
Vaccine Man’s role in the series is brief, but he leaves a lasting impression because of how seriously he takes himself. His exaggerated speeches about pollution and his grand sense of purpose make him a parody of classic villains.
His dramatic transformation is meant to be intimidating, but it only serves to make his eventual defeat even funnier. The fact that he meets an instant and unexpected end after all his grandstanding makes his character one of the most memorable jokes in the series.
8. Evil Natural Water
Evil Natural Water is an oddity among the monsters, as it is just living water. Its presence alone is enough to make it one of the strangest and funniest members of the Monster Association. The idea of a villain with no face, voice, or clear personality being considered a threat is already amusing.

While it is powerful, its unusual nature makes it difficult to take seriously. Watching heroes try to figure out how to fight something that has no solid form adds to the comedy of its existence.
9. Hundred-Eyes Octopus
Hundred-Eyes Octopus is exactly what its name suggests—a giant octopus with too many eyes. While this design could have been scary, it comes across as absurd instead. Its many eyes give it an expression that often looks more confused than menacing.
The way it moves and reacts to battle situations adds to its comical appearance. Instead of looking like a fearsome deep-sea monster, it seems more like something that belongs in a children’s fantasy story.
10. Pig God
Pig God is technically a hero, but his behavior and design make him feel like he belongs in the Monster Association. His entire fighting style revolves around eating enemies, which makes for some of the most bizarre moments in the series.
Watching a giant, overweight man casually swallow monsters whole is both unsettling and hilarious. His nonchalant attitude, combined with his absurd ability, makes him one of the most entertaining characters in the series.
The Monster Association is filled with powerful creatures, but some of them stand out more for their comedic value than their actual strength. Whether through their exaggerated designs, ridiculous personalities, or embarrassing defeats, these monsters bring much-needed humor to the story.
Their presence ensures that even in the middle of intense battles, there is always room for laughter.
