Epsilon Universe

The Epsilon Universe is a fictional shared universe created by the company Epsilon Publishing in which most of the comics published by them take place. The term is used to specifically refer to the primary continuity of Epsilon, which features most of the company's biggest characters such as Voltage, The Immortal Zombie, Shade, Dash, Paragon, Spartan, The Word, Magistrate Earth, Detective Lovecraft, and Alpha. It also features teams like The Shield, Cosmic Knights, the Runners, and the Pack, as well as supervillains such as Soliara, Dynasty, Ozymandias Rex, The Good Doctor, Siphon, and the Craftsman.

Like other comic companies, Epsilon also takes place within a multiverse, which is stated to consist of 24 "Sectors" named after letters of the Greek alphabet which consist of a million worlds each. The main universe of the comics is referred to as Epsilon-Prime, as it is the first and thus primary world in the Epsilon Sector of the multiverse.

History
The characters in the Epsilon Universe were initially not intended to be a shared universe, as the editors at the time believed it would be too confusing. However, following the success of other crossover works at the time, it was decided to print a versus story in the pages of Big Time Comics #8 (1941) in which the heroes Manhunter and The Human Rocket were tricked by Nazis into believing the other was a traitor. At the time, this was dubbed a "hypothetical tale", implying it wasn't canon, but it has since been retconned into continuity. Before this retcon though, the first canonical crossover between characters came in Captain Tomorrow #12 (1942), in which the titular Captain Tomorrow teams up with his fellow heroes Hourglass and The Human Rocket to take on the villain Tulok the Terrible. This story was unique at the time, as it ended with the three heroes agreeing to further team-ups which were seen in the comic The Heroes Three. At the time, events from one comic having impacts in another was unheard of and The Heroes Three went on to become a landmark of the company at the time, with events from that comic being referenced in and influencing the stories the titular three heroes were featured in.

In the late 1940s to the early and mid 1950s, there were limited attempts to continue the connected universe, with some going as far as to claim it was dead during this period. However, after the success of DC Comics's various reboots of their characters, some attempts were made to once again build an interconencted universe with mixed results. Some fans have gone as far as to claim the universe only came into its own in the mid 90s, when the crossover event Invasion was published, featuring a team-up of the company's seven most popular characters at the time. Since then, however, frequent team-ups, comic crossovers, and more have occured, most of which being well-regarded by fans. Additionally, in 2001, Epsilon bought fellow comic company Neo Comics, best known for works such as Might and Mister Midnight, and added their characters to its universe which, while not unheard of, was uncommon at the time.

The universe has also been established to exist within a multiverse since very early on in its creation, as an issue of the comic Tales Beyond the Stars in the 1940s claimed that there were many worlds and the one the stories took place on was the Epsilon Universe. This was later retconned into how it is now, with there being 24 Sectors and the prime universe being Epsilon-Prime. Along with this, the series exists in a sliding timescale, with characters aging very slowly and events being retconned to suit the present day.
