Top 1 in Top 10 strongest demons in Chainsaw Man manga.
As the most fearsome of all the demons in the Underworld, it is undeniable that the Chainsaw Man is the most powerful of all the demons that reside within Denji. Compared to the other Devils, Pochita and Denji's contract was quite unexpected. After Denji handed over the contract to Pochita, Pochita allowed Denji to transform into the Chainsaw Man Devil, a form that brought terror to every Devil in the Underworld.
What makes the Chainsaw Man truly terrifying is his ability to eat demons and completely obliterate their existence, to the point where no one can even remember them. Showing how strong Chainsaw Man is, Makima, one of the strongest Devils along with the others, couldn't even defeat him.
