Characteristics

Location
Fisto! can be found on the upper area of the Derelict Power Plant right across from MDPL-13 Power Station next to a computer on a desk. This is northwest of Minefield. Inside the power plant are multiple Feral Ghouls, and, depending on your level, you may also encounter multiple Feral Ghoul Roamers, Glowing Ones and, with Broken Steel installed, Feral Ghoul Reavers.

Appearances
Fisto! only appears in Fallout 3.

Trivia

 * The Fisto! is a reference to the He-Man and the Masters of the Universe character Fisto, whose distinguishing feature was the large metal fist on his right hand.
