Take them all (one at a time).

"You're going to help me catch as many as I tell you to. Understood?"
"Yes, Master," Hyper-Girl/Wendy says.
"You aren't free until I will you to be. Understood?"
"Yes, Master."
"I have your word as a Superheroine," you ask.
"Yes, Master. You have my word, Master."

You untie your new (still-powered) ****. You know that her unwavering morality will **** her to do nothing against you now.

You send her home and prepare your fun takedowns of the group. You could go a number of ways with this...

You decide to go right to the top. If they need help, they'll go to Power Woman/Ms. Sampson, so it is best to take her out. It could play well into your long-term plans.

The next day, you prepare your trap. You use your limited ability to manipulate Reality itself to make the Coach give you a pass for Lunch and the next Class. You let her make up the proper excuse.

You take Wendy along as insurance- just in case things go awry.

You meet Ms. Sampson in her Office and offer her a drink. She doesn't know that *you* know her Secret Identity and Wendy's presence makes her feel safer. If only she knew.

You put in an additive to help cover the taste of the Diet Soda, making sure that she drinks enough. Will that affect how it works though?

As you go over some Routines on paper with Wendy and Ms. Sampson, you see her drink the whole thing down. With half an hour left to play, you decide to make your move.

Grabbing some cuffs from Wendy's purse (which you made her bring), you slip behind the Coach on the pretense of grabbing a file. You signal for Wendy to go over and grab her. Her strength is great, but about half of what Power Woman's is.

As you go to cuff the Coach, you hope that this works...
