Power fist

A power fist is a type of weapon that appears in every incarnation of the Fallout universe released thus far; one of very few weapons to claim such status. In all of its incarnations, it appears as some variation of glove or armoured gauntlet, with a powered ram or similar device which improves the impact of the wielder's Unarmed strikes.

"Big Frigger" Power Fist


The Big Frigger Power Fist is an armored gauntlet produced by BeatCo, and uses energy cells to drive a kinetic storage device, similar to the device used in the super sledge.

Big Frigger Mega Power Fist


 The Big Frigger mega power fist is a new model, upgraded from BeatCo's previous 'Big Frigger' power fist. A promotional excerpt states that it has upgraded power servos to increase its strength. However, it uses twice as much charge from power cells as well. 

Pneumatic Power Fist


The pneumatic power fist (referred to in-game simply as a power fist) is an Unarmed-class weapon which appears in Fallout 3 and Fallout: New Vegas. It appears as an armored gauntlet, like that off a suit of power armor. However, it appears to use a pneumatic ram instead of kinetic energy devices, making it function in a manner closer to that of the impact gloves. (see below)

Ballistic Fist


The ballistic fist is a gauntlet with a small pressure plate-activated shotgun grafted to it.

Impact Gloves


Impact gloves are an Unarmed class of weapon exclusive to Fallout Tactics. They appear to be a leather glove with a pneumatic piston bolted to the back of the hand, which extends on contact with the enemy for additional striking force. While not, strictly-speaking, a power fist, it is included as it functions in a more or less similar fashion. Impact gloves do not require ammunition.

Electric Power Fist


The electric power fist is a glove weapon that appears in Fallout: Brotherhood of Steel. It uses an internal power source, negating the need for power cells. The impact of the electric power fist deals damage similar to a raygun shot.

Mega Electric Power Fist


The mega electric power fist is an enhanced version of the electric power fist that appears in Fallout: Brotherhood of Steel. It uses an internal power source, negating the need for power cells. The impact of the Electric Power Fist deals damage similar to a raygun shot.

Unnamed model


The power fist was expected to return in Van Buren. It would've most likely functioned in a manner similar to the Big Frigger power fist.

HERAKLES
Herakles was one of the Enclave-Poseidon Energy weapon programs that was abandoned during the Great War. The Prisoner could find these plans and rebuild the Herakles model.
