Jasper Jacks is a fictional character from General Hospital, an American soap opera on the ABC network. He has been portrayed off-and-on by actor Ingo Rademacher since 1996. The role was temporarily played by Gideon Emery during Rademacher's absence in January 2008. Jack gained popularity due to the love triangle involving him and supercouple Sonny Corinthos and Brenda Barrett. When Brenda left the show, it continued on with Sonny and Carly Benson. Sonny and Jax became enemies due to their frequent affections for the same woman. Jax has left the show numerous times, but for the most part has been a steady presence since his debut.
