Hellboy Universe

The Hellboy Universe is the fictional universe of the Hellboy comic and its various spin-offs, created by Mike Mignola. Its first appearance was in a black-and-white, four-page promotional comic by Mike Mignola with a script by John Byrne published by Dark Horse Comics in San Diego Comic-Con Comics #2 (19 August 1993), distributed at the San Diego Comic-Con. There are currently 52 trades and 2 OGNs in the series.

This series, focused on the titular Hellboy, spawned the Hellboy Universe. There are generally two types of Hellboy stories; Pre-Cavendish (stories set chronologically before the first miniseries Hellboy: Seed of Destruction) and Post-Cavendish (stories set chronologically after the first miniseries). Post-Cavendish stories are usually very continuity heavy, and require the reader to be relatively familiar with Hellboy's history. Pre-Cavendish stories tend to be primarily short, stand-alone stories.

In addition to the comics, the Hellboy novels written by author Christopher Golden are also considered in-continuity, although his short stories are not.

Hellboy stories are collected in oversized hardcovers known as library editions.

Unlike previous Hellboy stories, Hellboy in Hell was an ongoing series. It was not a monthly series, but rather a new issue came out when it is finished. When there was an arc spanning multiple issues, each of those issues came out monthly.

On July 8, 2014, just prior to SDCC 2014, Entertainment Weekly and Nerdist announced the new title, kicking off with a five-issue miniseries. It is set in 1952, beginning with Hellboy's first mission for the B.P.R.D., a series of grisly murders in the Brazilian jungle. The title debuted in December 2014. This series is simultaneously a spin-off of Hellboy and B.P.R.D.
