Constrictor (DC)
From Multiversal Omnipedia
The Constrictor was a pink-colored imprisoning bubble-like object used by Saraar to catch Green Lantern (Hal Jordan) and the Flash when they came to the Doragians' world. The two heroes cooperated to realign the Constrictor's molecular structure so that the Flash could vibrate them free. Green Lantern later created a Constrictor to imprison his and Flash's own animated shadows.
