There’s a popular belief that Emporio Ivankov from One Piece is inspired by Dr. Frank-n-Furter from The Rocky Horror Picture Show. While that may be true to some extent, I believe his design resembles Cassandro El Exotico even more. Cassandro is a well-known Mexican-American wrestler who gained fame in Lucha Libre from the late ’80s to the early ’90s and has been a significant figure in the LGBT community within wrestling. Recently, a biopic about him, starring Gael García Bernal, was released on Amazon Prime.
Oda has often drawn from wrestling and Lucha Libre for character inspiration, as seen in Ivankov’s use of wrestling techniques. I think the visual similarities are striking, and the images really highlight this connection.
