Abnormal brain

The abnormal 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 you can issue commands to it, it will not leave your party unless you kill it.

Appearances in games
The abnormal brain only appears in Fallout 2.
