Soon after the search for the diamond started, Luke and Robert teamed up in their hunt (via Soap Central). However, Alex and Tony, who were working together, had a leg up on their search and were aware that the base of the Ice Princess held the formula to a massive weapon. Both groups followed the trail to Cassadine Island in Greece where it was revealed that Mikkos Cassadine (John Colicos) wanted to use the Ice Princess to freeze the world. In a bizarre “General Hospital” plot line, Mikkos revealed he planned to plunge Port Charles into an ice age as a warning to world leaders so he could garner power over them.
By this time Laura Webber (Genie Francis) had joined forces with Luke and Robert, who had discovered an ice chamber on the island where Mikkos was keeping frozen bodies. After a physical struggle between Luke and Mikkos, Luke was able to throw Mikkos into the ice chamber, killing him. Luke then guessed the password to the weather machine — “iceprincess” — and was able to shut it down, effectively saving the world (via Soaps In Depth).
