A very brief history of the "inhibitor collar", based on my research and recollections.

-1957 Oms en série {aka Fantastic Planet):
Tiny humans imprisoned on a planet of gigantic alien beings known as Draags. We follow one, of which, is treated as a toy by a Draag child, held captive by "inhibitor collars". Written by Stefan Wul.

-1968 Star Trek episode- Gamesters of Triskelion:
Kirk, Chekov, and Uhura trapped on alien planet and forced to participate in gladiatorial games. Imprisoned with "inhibitor collars" that shock them. Written by Margaret Armen.

-1991 Wedlock:
Rutger Hauer film about a diamond thief sent to an experimental prison using "inhibitor collars" that connect you to another inmate and will explode if proximity distances from one another are not close enough. Broderick Miller wrote this.

-1993 Fortress:
Christopher Lambert film about a couple escaping America to the Canada border in order to have a second child (hmmm how prophetic). Lambert's character is caught and imprisoned in a maximum security prison and implanted with a device called an intestinator. Similar but not quite the same.

-2000 Batoru Rowaiaru (aka Battle Royale)
A group of grade school students are sent to an island to compete against one another with "inhibitor collars" to ensure no one escapes.

There was also the latest appearance of Wolverine and the X-Men.

Not this is not a critical examination of your use of it or a declaration of plagarism on your part. I like your versions better, because there has clearly been some thought put into the workings of them. I like the updated version from YJ: Invasion, especially episode "The Fix". Thank you for your time.
