In the world of Chainsaw Man, there are countless demons — ranging from harmless and weak to truly terrifying. Each one embodies a specific fear, and the stronger the fear among humans, the more powerful the demon. But who is the strongest among them?
The answer is simple — it's the Chainsaw Demon. Even the oldest and most powerful beings fear him. When Denji transforms into Chainsaw Man, deadly blades sprout from his body, allowing him to literally tear enemies apart.

However, the main threat he poses lies in his ability to absorb other demons, erasing their existence from reality. When he destroys a demon, the fear it represents disappears from human memory. This is why the Chainsaw Demon is not just a hero but a nightmare for demonic entities, who seek to eliminate him at any cost.
