He was initially an enmascarado ("Masked") mascot of the La Peste Negra group, helping them cheat against their opponents, but transitioned to a full-time Micro-Estrella wrestler in April 2017.

The wrestler later known as Zacarías started his wrestling career in 2007, working under the ring name KeMorito, an "evil version" of Consejo Mundial de Lucha Libre (CMLL) Mini-Estrella Mascota KeMonito.

When he teamed with La Peste Negra, Bucanero wore ring gear that looked more like Jack Sparrow from the Pirates of the Caribbean film series than he usually did.

The mascota was initially called "Perico" (Spanish for parakeet) and would accompany members of La Peste Negra to the ring occasionally helped them cheat during matches.

[8][9][10] In early 2017 CMLL recruited Zacarías and fellow mascota Mije to help establish a Micro-Estrellas ("Micro-Stars") division, featuring only wrestlers with dwarfism.

[14] For the 2018 Día de Muertos ("Day of the Dead") supercard show Zacarías, Mije, and Chamuel lost to Microman, Atomo, and El Gallito, two falls to one.

[15][16][17] Four weeks later the Micro-Estrellas also appeared at CMLL's Leyendas Mexicanas ("Mexican Legends") show where Zacarías, Mije, and Chamuel lost to Microman, El Gallito and Guapito in the second match of the night.

[27] They also made a special appearance for The Crash Lucha Libre, one of Mexico's largest independent promotions, with Microman and Gallito once again defeating Chamuel and Zacarías in their March 2, 2019 match.

[29][30] Súper Luchas magazine described the Micro-Estrellas division debut match between Microman and El Gallito vs. Mije and Zacarías, as "an encounter with a fall that literally stole the night.
