Pochita is the Chainsaw Devil who embodies the fear of chainsaws and was the original Chainsaw Man before becoming Denji's heart. Despite being regarded as the Devil that Devils fear the most and considered one of the most powerful entities in the series after the Primordial Devils, he also can be sentimental and even cry a bit. You can see it not only in our fanart Chainsaw Man Pochita Crying Sticker.
