Crisis On Infinite Earths torrent

The title was originally conceived to be a celebration of DC's 50th anniversary; however, Marv Wolfman and Len Wein saw it as a chance to clean up DC's rather convoluted continuity (which was thought to have put many new readers off buying DC titles) that had built up over that time. The term "Crisis" was a word used frequently in DC Comics of the time, as it denoted an inter-dimensional crossover, such as the yearly Justice League/Justice Society crossovers that began with "Crisis on Earth-Two".
Wolfman came up with an idea which would reach across the entirety of the DC Universe and its 50-year history. First of all, he came up with the character of the Monitor who was initially a faceless character used in many of DC's titles over the course of a year. The Monitor supplied DC's villains with equipment in order to test its heroes for the Crisis ahead. As a result, the character was seen to be a villain himself and his real reasons were not revealed to the reader until Crisis #1.
