Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
When this card inflicts battle damage to your opponent: 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. Once per turn: You can target 1 monster your opponent controls with a Level less than or equal to this card's; take control of it until the End Phase.
