The role of Victor Cassadine was originated by actor Thaao Penghlis in 1981 for the Ice Princess Storyline. Penghlis reprised the role on and off on a recurring basis from January 31 to September 16, 2014.
In 2021, the role was recast with actor Charles Shaughnessy, who previously played the short-term character of Alistair Durban in 1981. Shaughnessy made his first appearance as Victor on September 2, 2021.
The role of Liesl Obrecht was originated by actress Kathleen Gati on August 24, 2012 and she's been recurring since then.
Victor and Liesl were lovers in the 1980s. Liesl thought there was a possibility that Victor could be her son Nathan’s father.
In 2021, Liesl and Scott Baldwin’s private plane to St. Lucia is hijacked by two Greek men. Scott is thrown overboard with a parachute.
Victor is shown to be alive and he is the one holding Liesl captive in a castle (possibly Cassadine Island). He gives his condolences for Nathan’s death and says he spared Scott.
