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 portrayed by Gideon Emery during Rademacher's absence in January 2008. Jax 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 mortal 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.
