Koshchei the Deathless #1

Hellboy's immortal foe! 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 Hellboy himself--in Hell. 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).

Characters: Hellboy, Koschei the Deathless
