Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
1 Fusion Monster + 1 DARK monster Once per turn (Quick Effect): You can target 1 face-up monster your opponent controls; place 1 Predator Counter on it, and if it is Level 2 or higher, it becomes Level 1 as long as it has a Predator Counter. When a monster effect activated by your opponent resolves, negate the effect if that monster has a Predator Counter. * The above text is unofficial and describes the card's functionality in the OCG.
