The 2001 Sin Piedad was the second event under that name that CMLL promoted as their last major show of the year, always held in December.
The event featured six professional wrestling matches with different wrestlers involved in pre-existing scripted feuds, plots and storylines.
Wrestlers were portrayed as 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 followed a series of tension-building events, which culminated in a wrestling match or series of matches.
In mid-2000 Shocker, Bestia Salvaje and Scorpio Jr. teamed up in Consejo Mundial de Lucha Libre (CMLL) to form a group called Los Guapos (The Hansome Ones").
[3] The group took part in a large number of vignettes with them visiting beauty spas and talking about their looks, which played for comedic value, especially considering none of the wrestlers were considered "classically beautiful", in fact Scorpio, Jr's father was nicknamed El Rey Feo ("The Ugly King") and the son took after his father.
[5] In the fall of 2001, Tarzan Boy found himself on the opposite side of both Brazo de Plata and Giganté Silva in a number of handicap matches.
The third and final fall saw El Satánico pin Mr. Niebla, ending the match after twelve minutes and six seconds.
The four had originally started working together in World Championship Wrestling (WCW) and continued to do so in CMLL under the La Familia name.
The rudo Familia took on the tecnico team of some of the most popular names in CMLL at the time, El Hijo del Santo and Negro Casas teamed up with Rey Misterio Jr. who made a special appearance in CMLL between working for WCW and starting for World Wrestling Entertainment (WWE).
The third fall of the match saw the advantage change from moment to moment as neither man dominated, but in the end Shocker took advantage of a miscommunication between Charles as Bestia Salvaje and Scorpio Jr. who tried to interfere in the match and pinned Emilio Charles Jr. for the third and final fall.
