Berthier used this attack against Sailor Mercury when the Spectre Sisters fought the Sailor Senshi. Several episodes later, Berthier used the attack again the infused the Crystal Point, the Chess Tower, with Dark Power to prevent it from being used to create Crystal Tokyo.
In Bishoujo Senshi Sailor Moon: Another Story, Berthier as well as Nabu were able to use the move, however, the attack took the form of multiple slashes of water that only harmed enemies rather than freezing them.
