Rafael Ramírez Solorza (born February 24, 1976) is a Mexican Luchador, better known by the ring name Monster Clown and previously worked as Aliens between 2004 and 2007 before adopting his current ring name. He is currently under contract with Lucha Libre AAA Worldwide. He is best known as Monster Clown, being part of Los Psycho Circus along with Psycho Clown and Murder Clown where they portray a trio of "evil clowns". Ramirez previously worked under the ring names Highlander and Aliens before becoming a part of Los Psycho Circus. In the summer of 2009 he was forced to change his ring name from Zombie Clown to Monster Clown due to copyright problems. Professional wrestling career Ramirez began his professional wrestling career in 1997 as the enmascarado (masked wrestler) "Highlander" working primarily in and around the Tijuana, Baja California area. He some times worked on Lucha Libre AAA World Wide (AAA) shows when the promotion ran shows in Tijuana, but was not a full-time member of the roster. In 2004 he began working more for AAA as AAA owner Antonio Peña came up with a new ring character for him called "Aliens". The "Aliens" character was that of an actual alien from space who had come to earth to wrestle. He was even given a mascota (a Mini-Estrella companion) called "Mungo". The odd duo joined up with Madrox and Kriptor to form the group "Los Alienigenas" and worked a feud with the colorful duo of El Alebrije and Cuije. When Peña died in the fall of 2007 the Aliens character quickly dropped as it did not fit with the direction the new management wanted. Los Psycho Circus In late 2007 AAA decided to repackage Aliens turning him into "Zombie Clown" and making him a part of Los Psycho Circus along with Psycho Clown and Murder Clown. Unlike previous Clown characters who wore fabric masks Los Psycho Circus wore rubber masks with more horrific, twisted facial expressions, inspired by the movie Killer Klowns from Outer Space. Zombie Clown's mask features rotting yellow teeth, skin blotches and a small blue tophat. The team made their debut on December 14, 2007 during a show in Chilpancingo, Guerrero where they defeated Real Fuerza Aérea (Aero Star, Super Fly and Pegasso). Los Psycho Circus was physically larger than most of the AAA wrestlers and soon established themselves as a dominant force in the ring as
