Alexander, Kevin Nowlan and Scott Hampton. In 2007, following after 2005's The Island, British artist Duncan Fegredo took over art duties on the ongoing story arc of Hellboy from Darkness Calls onwards. Mike Mignola returned as the full-time artist for Hellboy in 2012 for the series' conclusion, Hellboy in Hell. Abe Sapien In 1998 the first Hellboy spinoff, Abe Sapien, was launched. It was not written by Mike Mignola, but it did feature his Hellboy short story "Heads" as a back-up. Abe Sapien did not take off properly until a decade later in 2008's The Drowning. Since then it has had several short stories and beginning in 2013 it became an ongoing series with Scott Allie as the lead writer with Mignola. Lobster Johnson Lobster Johnson was the next spinoff, debuting as a back-up feature in 1999's Box Full of Evil. The series got its own title later in 2007's Lobster Johnson: The Iron Prometheus. It returned again with the miniseries The Burning Hand in 2012, followed by various short stories. B.P.R.D. B.P.R.D. was the third spinoff, but it was the first one which was conceived to be more than just a one-off side story, but rather a series of stories. It began with 2002's Hollow Earth, which continued on from Hellboy: Conqueror Worm. Beyond that followed a series of short stories designed to explore what the B.P.R.D. series could be. 2004's Plague of Frogs was the story that solidified what the series was, and would set the direction for future books to come, so much so that the first major story cycle is collected in omnibus editions titled B.P.R.D.: Plague of Frogs. A vast majority of the stories in this era were co-written with John Arcudi and drawn by Guy Davis. B.P.R.D.: Hell on Earth is the main series continuing after the catastrophic events at the conclusion of the Plague of Frogs cycle. Guy Davis left the series in 2011 with the conclusion of Hell on Earth: Gods. Tyler Crook became the new ongoing artist beginning with Hell on Earth: Monsters, but he is joined by several regular artists, most notably James Harren and Laurence Campbell. Continuing where Hell on Earth left off, The Devil You Know is written by Mike Mignola and Scott Allie with Laurence Campbell serving as the regular artist.
