Gilbert Cosme (born May 25, 1975) is a Puerto Rican professional wrestler, better known by his ring names El Mesías and Ricky Banderas. He began his career in the International Wrestling Association based on Puerto Rico. While performing in the company, he won the IWA World Heavyweight Championship on five instances and held minor championships on fifteen separate occasions, before leaving the company in 2006. On March 12, 2006, he debuted in Asistencia Asesoría y Administración, a promotion based in Mexico, as a character named Muerte Cibernetica and was involved in an angle where this character was “killed”. In November 2006, Cosme was involved in the tapings of the Wrestling Society X television series, where he was the second and last wrestler to win the WSX Championship.
Following a month of performing in the International Wrestling Association, Cosme returned to Asistencia Asesoría y Administración in a special event presented by the company, this time under the ring name of El Mesías. In September 2007, the company organized a unification tournament where all of the champions and first contenders participated. Over the course of the tournament, he won the GPCW Super-X Monster Championship and IWC World Heavyweight Championship, and on the tournament’s finale, he became the first wrestler to win the AAA Mega Championship. While working in Mexico, Cosme signed a contract with Total Nonstop Action Wrestling (TNA) where he debuted as Judas Mesias on September 13, 2007. In March 2008 his association with TNA came to an end and he focused most of his time on AAA. In 2010 Cosme debuted for Puerto Rican World Wrestling Council, where he won the Universal Heavyweight Championship.
