It gives you total control over Power Girl

You turn to Power Girl. She stares back at you blankly. When you turn back around the mad scientist is running away.

“Power Girl, he's getting away!” you yell.

“Yes,” she responds, “he is.”

You wait a moment, but the blonde heroine continues standing there, watching you blankly. “Well? Aren't you going to grab him?”

“Do you want me to?”

“Well... yeah!”

Power Girl flashes past you, then instantly speeds back. She holds the crazy man in the lab coat up by the back of his pants, dangling him a few feet off the ground. Her eyes still follow you blankly.

“What did you do to her?”

The villain smiles arrogantly. “I created a mind control ray! However, it only works on someone with incredibly dense flesh, like a Kryptonian. The beam just passes through anyone else. That's why it passed through you. But after hitting someone dense enough, the rebound blast causes a reaction with whoever it hits. That reaction was supposed to make her my **** forever!”

You step in close to the madman and speak quietly. “But the rebound hit me, instead.”

His smile drips away. “Well... yes. And it took me three years to grow the crystals that make the gun work, so I guess she's yours now.”

Police sirens sound from up the street. You glance at Power Girl and marvel at her blank stare. “So you're saying she's my **** now? Can you reverse it?”

“Nope. But we could use her together! Come on, you've got this powerful, influential, and damn hot superhero as your total **** forever. You owe me! Just tell her to let me go and we can do anything with her! Anything!”

You glance over at the police cars as they screech to a stop. Officers begin to pour out and approach you.
