Professional wrestler Efrén Tiburcio Márquez, commonly known under the ring name Mr. Niebla, died on December 23, 2019, from complications of a blood infection after dealing with health issues for several months leading up to his death.

[1][2] Prior to his death, CMLL had announced that they were holding a benefit show for Mr. Niebla on January 4 to help pay for his latest medical expenses, but with Mr. Niebla's passing it became a tribute show, El Ultimo Vuelo del Rey del Guaguanco ("The last dance of the King of Guaguanco"), with the money collected going to his family.

The event featured six professional wrestling matches with different wrestlers involved in pre-existing scripted feuds, plots and storylines.

CMLL announced that Olímpico, Rey Bucanero, and Shocker would all wear their masks for one night, after having previously lost them in a Lucha de Apuestas (bet match).

[6] The developing feud between Felino and Bárbaro Cavernario led to the dissolution of La Peste Negra as well as the two being booked in the main event of the 2020 Homenaje a Dos Leyenas show, with both men risking their hair in a Lucha de Apuestas match.
