Guerra de Titanes 2018-B was a professional wrestling event produced and scripted by the Mexican professional wrestling promotion Asistencia Asesoría y Administración (AAA) or Triple A. The event took place on December 2, 2018, and was held in the Palenque de la Feria in Aguascalientes City, Aguascalientes, Mexico. It was the second Guerra de Titanes event of the year and was broadcast on Twitch.tv.
Starting in 1997 the Mexican professional wrestling, company AAA has held a major wrestling show late in the year, either November or December, called Guerra de Titanes ("War of the Titans"). The show often features championship matches or Lucha de Apuestas or bet matches where the competitors risked their wrestling mask or hair on the outcome of the match. In Lucha Libre the Lucha de Apuetas match is considered more prestigious than a championship match and a lot of the major shows feature one or more Apuesta matches. The Guerra de Titanes show is hosted by a new location each year, emanating from cities such as Madero, Chihuahua, Chihuahua, Mexico City, Guadalajara, Jalisco and more. In 2016 AAA moved the Guerra de Titanes show to January, with the 2017 version continuing that trend.
The Guerra de Titanes show will feature eight professional wrestling matches with different wrestlers involved in pre-existing scripted feuds, plots and storylines. Wrestlers portrayed 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.
