The tournament is a Gauntlet match featuring eight to thirteen AAA wrestlers ranging from mid-card to main eventers.
In 1992 then-Consejo Mundial de Lucha Libre (CMLL) booker and match maker Antonio Peña left the company alongside a number of wrestlers to form the Mexican professional wrestling, company Asistencia Asesoría y Administración, later known simply as "AAA".
[16] The following year AAA held the second ever "Antonio Peña Memorial Show", making it an annual tradition for the company to commemorate the passing of their founder.
[18][19] The Héroes Inmortales XVI show featured professional wrestling matches with different wrestlers involved in pre-existing scripted feuds, plots and storylines.
Wrestlers portray either heels (referred to as rudos in Mexico, those that portray the "bad guys") or faces (técnicos in Mexico, the "good guy" characters) as they follow a series of tension-building events, which culminate in a wrestling match or series of matches.
