Gilbert Cosme (born May 25, 1976) is a Puerto Rican professional wrestler widely known by the ring names Ricky Banderas, El Mesías, Muerte Cibernetica and Mil Muertes. Over a multi-decade career he has worked for prominent promotions in Puerto Rico, Mexico and the United States, earning recognition for strong character work, theatrical presentation and a style that blends lucha libre technique with heavyweight brawling. For a summary of his professional background see a published career overview.

Early career and rise in Puerto Rico

Cosme emerged as a notable figure in Puerto Rico's wrestling scene with the International Wrestling Association (IWA), where he became a major draw. During his time with the promotion he captured the IWA World Heavyweight Championship on multiple occasions and accumulated a series of regional and secondary titles that established him as one of the company's top performers. His success in Puerto Rico provided the platform to expand his work internationally and to develop the larger-than-life personas that would define his career. Several pieces of his IWA tenure and title history are documented in promotional records and title lists (IWA, title lists).

Work in Mexico and character evolution

In 2006 Cosme began wrestling in Mexico for Asistencia Asesoría y Administración (AAA), debuting under the masked, ominous identity of Muerte Cibernetica. In AAA he evolved the El Mesías persona, a dominant, messianic character presented as an imposing figure in major storylines. He participated in a high-profile tournament in the promotion that led to him being recognized as an early AAA World Heavyweight Champion, a milestone that increased his visibility in the Mexican wrestling market. His Mexican run showcased his ability to adapt presentation and ring psychology to different audiences and formats.

Appearances on U.S. television and Wrestling Society X

Cosme also appeared on the televised project Wrestling Society X in 2006, a short-lived U.S. program that mixed music and wrestling. On that show he became the second and final WSX Champion, a title that reflected the program's brief but memorable broadcast. Around this period he negotiated and signed professional terms with an American company, which led to work under a new persona in the United States (contract details).

Total Nonstop Action and later television work

In September 2007 Cosme began appearing for Total Nonstop Action Wrestling (TNA) under the ring name Judas Mesias. His TNA run provided exposure on U.S. cable television and involved storylines that capitalized on his size and character work. After leaving TNA in 2008 he returned to freestyle bookings and to the Mexican circuit, later taking a leading role in the cinematic wrestling series Lucha Underground as Mil Muertes. He debuted in the Lucha Underground television series in November 2014 and became one of the program's emblematic, supernatural characters.

In-ring style and personas

Cosme's work is marked by a focus on theatricality and strong visual identity: masks, elaborate entrances and character-driven storytelling. In the ring he combines power moves, strikes and classic lucha techniques, often portraying a dominant heel (villain) or an antihero depending on storyline needs. His ability to reinvent himself across cultures and companies—shifting between Spanish-speaking and English-speaking audiences—has been a defining feature of his longevity.

  • Multiple-time IWA World Heavyweight Champion during his Puerto Rico tenure and holder of several regional titles in that period (IWA, title lists).
  • Winner of the AAA tournament that yielded an early recognition as AAA World Heavyweight Champion in Mexico.
