Chernobog was a powerful Russian god that fell in an ancient war between good and evil. His spirit remained in the town where he met his defeat, looking for people to feed on to one day accumulate enough energy to return to his former glory and rejoin the war. He made a deal with a frustrated innkeeper to supply him with victims, so the innkeeper could continue harassing the tourists he despised. Chernobog found three more teenagers to feed on but was interrupted by another tourist,
Bruce Banner. Chernobog turned his wrath on Banner and soon had to deal with his alter-ego, the Hulk. Chernobog began absorbing Hulk's energy, but Hulk proved to be too strong and Chernobog’s host was too weak to handle it all at once. The Russian god had to retreat but promised he would return to face Hulk.
