Hibernation pod

Hibernation Pods were a type of technology used by the Wraith.

Overview
These pod-like structures were typically situated in the aft section of a Wraith Hive ship and consisted of number chambers that contained hundreds of sleeping Wraith. They were normally situated in the cieling of the chambers.

There existed a variant of the pods which were located on the ground and was built into the wall. An organic membrane surrounded the sleeping Wraith with a console nearby that allowed for the deactivation of the pod. A red liquid was present in the pod which encased the Wraith and numerous organic tendrils were attached to the sleeping individual. When deactivated, the liquid drained from the chamber and the tendrils retracted after which the membrane opened after which the Wraith awakened from their slumber.

History
When Colonel John Sheppard killed the Keeper, he inadvertently resulted in her awakening all the Wraith Hives in the Pegasus galaxy.

In order to survive from a deadly disease spread among them, Todd and his Hive ship crew entered into hibernation and hoped that the Atlantis Expedition would aid them in their crisis. Sheppard later awakened Todd from his sleep to enlist his aid when the Hive ship was experiencing numerous random malfunctions.
