Gabe

Gabe is an oversized cyberdog found in the X-8 research center's testing facility $$ He is bigger than the other usual police or military cyberdog and is more powerful due to a huge intake of Psycho.

Background
Gabe was the pet of Doctor Borous before the Great War. Gabe's savage nature comes as a result of Borous feeding him excessive amounts of the chem Psycho in his dog food. It is also revealed in dialogue with Borous that he fed him Buffout.

After the completion of A Brain's Best Friend, Doctor Borous reveals that Gabe was his only friend during his rough childhood and was the only loyal animal when he was working at the Big MT. When Borous was talking to him about Richie Marcus and Betsy Bright bullying him, Gabe would sit by his side with his head on his leg. Ultimately, with proper Speech checks the Courier can show Doctor Borous the error in his actions and make him feel remorse for experimenting on his loyal pet.

Appearances
Gabe appears only in the Fallout: New Vegas add-on Old World Blues.
