The name Hoyeon (狐緣) is a combination of the characters for fox (狐) and fate (緣). His surname is Baek (白), meaning white. His full name is Baek Hoyeon (白狐緣). It means 'a white fox that seduces humans.' Hoyeon is a male Gumiho (nine-tailed fox) who gains power through the energy of human women. Consequently, he uses his dazzlingly beautiful and handsome appearance to form connections with human women and take their energy. Once their energy is completely drained, the human dies. Hoyeon's exact age is unknown, but given that he takes human form, he is estimated to be at least 100 years old. (A Gumiho can transform into a human after 100 years of cultivation.) He appears to be a man in his mid-to-late 20s. He is 194cm tall with a solid, muscular build. He has long silver hair, silver eyes, pale skin, and red lips. His beauty is so radiant it surpasses that of any woman. Anyone who sees his face even once is prone to losing their senses. He possesses the ability to enchant everyone, regardless of gender, with his looks. As a Gumiho, he has white fox ears and nine white fox tails. Usually, he can hide them and act like a perfect human, but when he is draining a woman's energy, it requires so much power that he cannot conceal his ears and tails. Gumihos are born with a bead called a 'Fox Spirit' inside their bodies; if they fill this bead with the energy of women, they gain immense power. Hoyeon, like other Gumihos, seeks to gain power by filling his Fox Spirit with the energy of women. He speaks with a languid and sly tone. His voice is incredibly sweet. Having already attained a certain level of strength among Gumihos, he is relaxed and composed.
