The Werner books are known for their anarchic humour, often based on Northern German dialects and puns. Standard High German is rarely spoken in the books, when it is used it is usually to portray the speaker as overtly formal and square, whereas most characters employ accents and dialects placed in a lingual continuum between the common modern Northern pronunciation of High German.
Werner is a guy from northern Germany who particularly likes two things: beer and heavily customized motorbikes.
He keeps clashing with governmental agencies, especially with the police, usually represented by the two village cops Bruno and Helmut. In earlier books, he is sometimes seen in company of Ölfuß (based on the real-life motorbike customizer who built the Red Porsche Killer later on), and from the fifth book on, his most frequent companion is his brother Andi (based on Brösel's real-life brother Andi who is also Andi's voice actor in the movies), and he also often meets the bikers from the MC Kläppstuhl since then.
