Juan Escalera (born March 27, 1961) is a Mexican luchador enmascarado (masked professional wrestler) better known as Octagón. He is currently with Asistencia Asesoría y Administración (AAA), having worked for the company since it was founded in 1992. In 2011 he was inducted into the promotion's Hall of Fame. Octagón formed a Tag team with El Hijo Del Santo to take on Los Gringos Locos (Eddie Guerrero and Art Barr) in a double mask versus hair match on the first pay-per-view put on by a Mexican wrestling promotion. Over the years the Octagón gimmick has spawned a Mascot called Octagóncito and an "Evil clone" known as Pentagón.

Growning up, Octagón was mainly interested in Martial Arts and earned a black belt in Shotokan Karate. He viewed Lucha Libre (professional wrestling) only as a hobby. This changed when he met Raúl Reyes, former professional wrestler from the Veracruz area. Reyes convinced Octagón that his martial art skills could help him earn a living as a pro wrestler. After learning the pro wrestling basics, he made his debut in December 1981 as "Dragón Dorado" (Spanish for "Golden Dragon"). Not long after, he changed gimmicks (in ring persona) and became known as "La Amenaza Elegante" (Spanish for "the Elegant Threat") in 1982. He was not very successful as La Amenaza Elegante, although he did manage to obtain a contract with Mexico's largest, and the world's oldest, wrestling promotion, Consejo Mundial de Lucha Libre (CMLL).
