With the World War II raging, Hellboy's future guardian Trevor Bruttenholm enlists with Britain's Military Intelligence, where he uncovers a collection of strange messages. Believing it to be an occult language, he follows his hunch and is thrown into a world of animated corpses, deadly mystics, and Nazi agents. The treacherous journey leads him face to face with the man who will bring Hellboy to Earth--Rasputin! The two men responsible for Hellboy face off!

Bruttenholm and Sandhu reach the site of the Nazis' occult activity, where the shadowy ''Master'' himself is about to complete his occult experiment.

Longstanding mysteries from the Mignolaverse, finally solved in this collection of standalone stories! When did Rasputin find his calling to bring about Ragna Rok? How did the Visitor stay hidden on Earth for so long? And where did the legendary Sledgehammer armor really come from? These questions and more are answered in this new collection from the world of Hellboy! Three stories of instrumental side characters are explored in full, collected for the first time in a digital book perfect for any Hellboy fan's library. Hellboy creator Mike Mignola is joined by John Arcudi, Chris Roberson, Laurence Campbell, Christopher Mitten, Dave Stewart, and others to bring these hidden corners of the Mignolaverse to light. Collects Rasputin: The Voice of the Dragon TPB; Sledgehammer 44 TPB; The Visitor: How and Why He Stayed TPB.

Mignola returns to Hell and to the bizarre folklore that's filled some of his greatest books, reuniting with one of his favorite collaborators, Ben Stenbeck (Frankenstein Underground, Witchfinder: In The Service of Angels, Baltimore). This volumes collects the complete six-issue series plus bonus material. Sent to kill Hellboy by the Baba Yaga in Darkness Calls, Koshchei the Deathless hinted at a long and tragic life before being enslaved to the Russian witch. Now Koshchei relives every horrible act on his road to immortality and beyond, with none other than his one time enemy Hellboy himself--in a bar in Hell.

Little English girls are going missing, and the trail leads to a bloodthirsty cult wielding an ancient power of evil - the Cult of the Black Flame. No villain in the history of the Mike Mignola's line of books has caused as much death and destruction as the Black Flame. See what it was like when that power belonged to a secret order of priests hidden in the jungles of Siam. Christopher Mitten (Umbral, Criminal Macabre, Wasteland) joins Mignola and Chris Roberson (Hellboy & the B.P.R.D. 1953, iZombie) to explore an uncharted corner of the Hellboy's fictional world.
