Quite possibly a human brain. The color doesn't seem quite right and the left hemisphere of the brain has caved in on itself.”
This brain is one of the brains that can be found in the Sierra Army Depot and be used to build a mobile body structure for Skynet. However, using the abnormal brain makes Skynet so stupid that it can only act as a pack horse. Although it can be issued commands, it must be forcefully disbanded by destroying it.
Behind the scenesEdit
The abnormal brain and its acquisition are a reference to the movie Young Frankenstein where Igor accidentally destroys the optimal brain for the titular scientist's monster and takes a brain labelled "Abnormal" (which he reads as "Abby Normal") instead.
