Final Fantasy V
In Final Fantasy V, when Bartz and the other party members enter the Interdimensional Rift, they find a beautiful woman who was being held prisoner in the dungeon by a monster named Catastrophe. The party manages to defeat Catastrophe, and the woman rewards Bartz with a kiss.

Later, when the party try to leave Dimension Castle, the woman reveals herself to be Halicarnassus, who tells Bartz that he had taken his "kiss of death." A boss fight then begins, and Halicarnassus's first move is using Ribbit, temporarily turning the party members into toads. Once Halicarnassus has taken enough damage, he is defeated.
