Czernobog, a brutal Eastern European man, is actually the embodiment of a Slavic deity who causes all the bad things to happen in the world. He’s one of the old gods approached by Mr. Wednesday while rallying support for the fight against the new and powerful gods — Technical Boy, Media, among others — who are on the rise in society. Czernobog wields a sledgehammer — one he saved from his last job at a slaughterhouse — and he isn’t afraid to use it. Mr. Wednesday views Czernobog, if he can be persuaded, as a crucial fighter in the war he’s preparing to wage. Even if it looks like he’s never taken a shower. American Gods premieres April 30 on Starz.
