Career
He made his professional wrestling debut in 1968. He was one of only a few to bodyslam both André the Giant and Yokozuna. Today Wanz organizes strong men competitions in Austria called "Austrian Giants".
He also held several records for tearing telephone books
Arnold Schwarzenegger has cited Wanz as an influence on his fitness and bodybuilding career. Wanz made his pro wrestling debut in 1968 working in and around his native Austria.
Later on he would work as "Bulldog" Otto in Japan, primarily working for New Japan Pro Wrestling (NJPW). In the early 1970s he created the Catch Wrestling Association based in Austria but promoting shows in the surrounding countries as well.
On August 2, 1973 Wanz defeated January Wilkens on a show in Cape Town, South Africa to become the first holder of the CWA World Heavyweight Championship, bringing the championship back to Europe once the tour was over.
Over the years Wanz toured the United States, wrestling for various promoters. The reign ended 41 days later as Bockwinkel regained the championship. There have been persistent rumors that Wanz actually paid Gagne for the title run but that has never been confirmed by anyone.
Wanz regained the title a few months later but Bulletin Power would start a second reign in 1989.
Immediately after the match Wanz retired from active competition to focus on promoting the CWA.
