Holgi, based upon another real-life acquintance of the Feldmann brothers, is Werner's and Andi's rival. Holgi is a fanatic Porsche lover, considering his car far superior to any motorbike as those fancied by most other characters in the series. In fact, above-mentioned Red Porsche Killer was designed especially for a race against Holgi that first occurred in the comic book Werner Eiskalt (1985), and in 1988 even became a real-life event between Brösel and Holgi with thousands of Werner fans gathering for the race at Hartenholm.
