Social Behavior:

Extensive discussion of acceptance and tolerance, as Hellboy and his outlandish paranormal-busting team endure scorn and derision due to their appearance and odd natures after they go public. The public reaction to the relationship between Hellboy and his human girlfriend prompts a news anchor to ask rhetorically "Inter-species marriage -- A threat to traditional marriage?" A German-accented character's name, Kraus, is misspoken (somewhat derisively) as "Kraut."

Consumerism:

Some real-world brands are featured, like Tecate and Tecate Light beers and Baby Ruth candy bars. A brief snippet of Jimmy Kimmel Live is incorporated into the plot.

Drugs/Alcohol/Tobacco:

Characters speak of "needing a beer" as a prelude to talking about challenges and problems; mild comedic drunkenness involving non-human characters, resulting in a beer-fueled Barry Manilow sing-along; Hellboy smokes cigars.

Violence

Extensive fantasy violence throughout, including (but not limited to) super-powered fistfights, decapitations, stabbings, slashings, gun battles against gigantic monsters, and property damage. A paranormal supporting character controls flames to incinerate inhuman enemies. Pedestrians are threatened by debris and tentacles during a giant monster's urban rampage. Hellboy saves an infant from peril. A supernatural creature is interrupted as it prepares to eat a cat. A brutish monster is pulled into a large set of grinding gears and ground to bits. A character spends several scenes with a blade lodged in their body; epic battles between inhuman creatures; several supporting human characters are graphically devoured by tiny, hungry gnawing fantastic creatures. A supporting character commits a mystical murder-suicide.

Sex

Unmarried characters live together; a character takes a pregnancy test. Some kissing.

Language

Fairly mild, including "crap," "ass," "poop," "a--hole," "screw" and, obviously, "hell."
