Ancient brain scanner
Self-contained unit, portable component of a D.N.A. manipulator designed to measure the subject's physiology and feed it back into a genetic manipulation device
. The device is Ancient
in design, though likely created in some part by Anubis
to monitor the development of his genetically engineered creations.
Colonel Cameron Mitchell nicknamed the device an "ascend-o-meter."
Prototype - Major Altman finds and discerns the purpose of the Ancient brain scanner, returning it to Earth to use as a monitoring device for Khalek's rapid evolutionary growth.
