The world's destruction is often the ultimate goal of powerful villains in shonen anime, especially those driven by deep-seated hatred for humanity. For some reason, they aim to wipe out entire civilizations without hesitation. Unfortunately, they can only be satisfied once there is nothing left to kill and destroy.
Over the years, shonen anime has produced powerful villains who cause massive destruction wherever they go. Most importantly, these shonen villains nearly defeated their strongest rivals and came dangerously close to bringing about true world destruction. Without the heroes, these villains could have achieved their ultimate ambition.
Eren Yeager Flattened the World With the Rumbling
Attack on Titan's World-Ending Threat
Eren Yeager did not hold back in destroying the world in Attack on Titan. With an army of towering Wall Titans, Eren’s Founding Titan form led the ultimate genocide, resulting in 80% of humanity being stomped and burned to death.
For the sake of infinite freedom, Eren unleashed the Rumbling to protect his loved ones, sending a bold and reckless warning to anyone from Marley who wants to cage his fellowmen like vulnerable cattle again. In the end, Eren achieved his goal, leaving only a small fraction of humanity alive to carry the memories of his tragic choice and the consequences of his actions.
Kaiju No. 9 Caused Widespread Destruction
A Powerful Kaiju With High Combat Intelligence in Kaiju No. 8
Kaiju No. 9 is one of the most persistent antagonists in Kaiju No. 8, driven by a desire to spread chaos and destruction across Japan, treating human survival as little more than entertainment. He is violent and manipulative, but what makes him extremely dangerous is his high level of combat intellect as well as his adaptability.
On multiple occasions, Kaiju No. 9 nearly wiped out the Defense Force members with his attacks. Even Kafka Hibino in his Kaiju No. 8 form struggled to defeat him for good, largely due to his mind games and deceptive tactics.
Ryomen Sukuna Was Nearly Unstoppable
Jujutsu Kaisen's King of Curses Was Ruthless and Merciless
Stopping Ryomen Sukuna’s rampage in Jujutsu Kaisen required the combined strength of the most powerful jujutsu sorcerers in the series. Even the strongest of them all, Gojo Satoru, failed to put Sukuna to rest, resulting in his tragic demise. With deadly curse techniques at his disposal, including the ability to command the Divine General Mahoraga, Sukuna caused massive destruction in Japan.
Had Yuji Itadori and his allies failed in their mission to defeat Sukuna, the King of Curses would turn the world upside down with his overwhelming power and ruthlessness, plunging humanity into absolute chaos and despair. Thankfully, even Sukuna knew when to stop, accepting defeat before things went too far.
Koro-Sensei Held the Power to Blow Up the World
His Self-Destruction Could Erase the Entire Planet in Assassination Classroom
In Assassination Classroom, Koro-sensei is extremely vocal in his plans to destroy the Earth. He even claims that he is responsible for the moon’s destruction, provoking his students to stop him at the right time before he could actually destroy everything. Under his mentorship, Class 3-E evolved into highly skilled assassins, carefully trained and refined in the art of killing.
In reality, Koro-sensei has no actual intention of destroying the planet. However, his body is unstable and dangerous due to the extensive experiments it was subjected to. Had his body ever exploded, Earth and its inhabitants would have been annihilated in the blink of an eye.
Tomura Shigaraki Nearly Defeated the Heroes
All For One's Successor in My Hero Academia
By the end of My Hero Academia, Tomura Shigaraki has successfully surpassed All For One. He became the strongest villain for whom Izuku Midoriya went to extreme lengths to redeem, even at the cost of his abilities. With the All For One quirk at his disposal, Shigaraki fought to the very end, not only for his sake but also for all the villains who believed in him.
Tomura Shigaraki came dangerously close to defeating Izuku Midoriya on multiple occasions throughout the series. Even the strongest foreign heroes arrived to Japan’s aid but ultimately fell before they could stop him. If it weren’t for Izuku Midoriya and the accumulated damage Shigaraki had sustained from other heroes, he could have easily taken over the world or even destroyed it entirely.
The Evangelist Wanted a Second Great Cataclysm
The Evangelist Wanted to Burn the World in Fire Force
An abstract being who delights herself in chaos and destruction, the Evangelist is the main villain in Fire Force. Hiding in the shadows, the evangelist manipulated the members of the White-Clad in an attempt to burn the world until nothing remains.
For the most part, the Evangelist wants a repeat of the Great Cataclysm that destroyed a large portion of Earth. She nearly wiped out humanity with spontaneous human combustion, burning millions of victims to death.

Kaguya wielded immense power far superior to the combined might of the old Team 7, forcing the heroes to rely on a powerful sealing jutsu to get rid of her. Without the Six Paths Planetary Devastation jutsu, Kaguya would have conquered the shinobi world with ease. Fortunately, Naruto and Sasuke were around, fighting stronger together.
Frieza Temporarily Destroyed the Planet
Frieza Blew Up the Earth in Dragon Ball
Throughout Dragon Ball, Frieza is portrayed as a cruel and ruthless villain with a deep hatred for Saiyans and a general contempt for most other lifeforms. He has an extremely high opinion of himself, and even after being defeated or killed, he consistently returns stronger than before.
It’s no secret that Frieza has destroyed a lot of planets in the series, including Earth, which he blasted with an Earth Breaker attack in the Resurrection F film. However, thanks to Whis’ intervention, Goku arrived in time before Frieza could use the Earth Breaker attack again, preventing him from destroying the planet.
