Is “Buddhism has no such protector, and the Daoist Marshal Tianpeng is also unrelated to pigs.” true?

Chapter 008 of Journey to the West writes that Zhu Bajie was originally Marshal Tianpeng, who mistakenly entered a pig's womb. The original text: "我本是天河里天蓬元帅。只因带酒戏弄嫦娥，玉帝把我打了二千锤，贬下尘凡。一灵真性，径来夺舍投胎，不期错了道路，投在个母猪胎里，变得这般模样。" (Journey to the West, Chapter 008). Buddhism has no such protector, while in Daoism, Marshal Tianpeng is originally a star deity general. The novel borrows his name and merges it with folk pig demon legends to fabricate this character.
