Young Justice, Season 1

Amanda Waller:
I am the law of last resort. My name is Amanda Waller. I am not your mother, your maiden aunt, or your friend. I am your warden, and you are my prisoners. The proprietary collars you wear are custom designed to inhibit your specific meta abilities. No strength. No ice. In addition, the collars can and will be used to discipline inmates. A con who breaks the rules gets one warning. [Waller demonstrates] If order has not been restored, the next shock will render the offender unconscious. At the slightest hint of trouble this facility goes into lockdown. Belle Reve's walls are thick enough to hold Superman. We know - we've checked. No one's ever escaped Belle Reve. No one ever will.
