- Not to be confused with this subject's father, Bayon.
Bayon (バイヨン, Baiyon?) is a character of The Promised Neverland, and a minor antagonist of the Cuvitidala Arc. He was the son of the deceased owner of Goldy Pond, Bayon, and one of the heads of the Five Regent Families.
Has long black hair
Although the majority of the royalties and heads of the five regent families care more about their money and for their control over the world than the demon civilians, only Lord Bayon was an exception. Bayon was also shown to be concerned about the common folk, and therefore used to admire the former Lord Geelan.
On November 2047, in the Imperial City, Bayon stood in line with Pupo, Yverk, Noum and Dozza as they wait for the arrival of their queen Legravalima. Bayon reprimanded Dozza and told him to stand up. Dozza did not listen and instead reciprocated his rebuke. Pupo interjected the two's interaction and commented on how Bayon is as rigid as his father. The topic of conversation soon switched to a discussion on how Luce, Nouma, Nous, Bayon and Leuvis, had disappeared one and a half years ago. Dozza asked Bayon on his opinion on this subject, to which the latter replied by asking what are his implications. Not long after, Legravalima entered the room where Bayon and the rest stood as all of them bowed down to her.
Legravalima brought up the topic of the recent rise of the Factory Farms's theft rate. Bayon shared his view and opinions on the topic, and commented on how Lambda and other related farms had also been raided and destroyed, and actions should be done to cease the theft rate.
Lord Bayon greatly admired the former Lord Geelan, who was a selfless demon who cared about his underlings. However, Bayon's admiration for the former Lord Geelan faltered once the latter invaded the Tifari and revealed that he and his followers had consumed the royal families in order to ambush the heads.
