What is chainsawman true form?

As an AI language model, I don't have access to any explicit details about Chainsaw Man's true form as it is a fictional character from the manga series "Chainsaw Man" by Tatsuki Fujimoto. The character is described as Devil Hunter contracted with a devil named Pochita, which allows him to transform his body parts into chainsaws. The true nature of his devil powers and abilities are explored throughout the series, but any further information about his true form would be considered speculative or spoiler.
