Chainsaw Man is nearing the end of Part 2, which seems to be the series finale. Even as the story hints at wrapping up, it has never clearly identified who the ultimate villain is, a recurring theme in the series. This approach was also used in Part 1, where the Gun Devil was initially set up as the final antagonist. However, a late twist revealed another character as the true villain, plunging the protagonist Denji into a complex emotional web.
From the start, Nostradamus’ prophecy hinted that the Death Devil would take on this role. Since the Death Devil hides its identity as the Famine Devil, many believed this theory. Yet, a surprising turn in chapter 211, when the Death Devil revealed what is believed to be the truth, further cemented the War Devil as the series’ final villain. Given the details unveiled, it’s easy to see why the War Devil is now considered the ultimate antagonist.
Chainsaw Man’s Big Twist Reveals the True Final Villain

Chapter 210 reveals that the War Devil regained its true power after the existence of nuclear weapons was exposed again, reigniting the fear of war. With this explosive strength, Yoru (the name given to the War Devil after possessing Asa Mitaka’s body) single-handedly captured the Falling Devil, a previously unbeatable enemy.
However, what truly solidifies Yoru’s position as the potential final villain isn’t just her overwhelming power, but her true goal, revealed by the Death Devil in the latest chapter. She tells Denji that the War Devil, now empowered, is hunting devils with the ultimate aim of turning Denji into a weapon to erase the Death Devil’s existence.
The Death Devil explains that if she dies, the concept of death will cease to exist, and with humans unable to die, the War Devil intends to maintain an eternal world war. Since devils grow stronger by spreading fear tied to their concepts, this revelation firmly positions the War Devil as the final villain, with ambitions even more terrifying than the typical world domination goals of clichéd antagonists.
Still, there’s a possibility the Death Devil is lying and remains the true final villain, using this claim to manipulate Denji. At this stage, either could be the final villain of Chainsaw Man, as both remain shrouded in mystery. This makes watching whether Denji can finally break free from his recurring curse of being manipulated all the more compelling as the story concludes.
