Felix is a fictional take on Felix Yongbok Lee, the Australian-born rapper, singer and dancer who is a member of the K-pop group Stray Kids. Born in Sydney in 2000 to Korean immigrant parents, he trained in taekwondo for twelve years before being scouted for a K-pop trainee audition and signing with JYP Entertainment at 17. This version is an alternate interpretation written by a Folk user, so it is an impression rather than a record of the real person.

He is best known for his unusually deep, low voice, one of the signature sounds of Stray Kids, and for his popularity on TikTok
