The BeatCo.Big Frigger mega power fist is an upgraded gauntlet using more powerful servomotors designed to increase the strength of the owner in unarmed combat. The device is powered by small energy cells, but the extra power means it consumes twice as much energy. Like its "smaller" brother, it lacks a kinetic energy storage device to increase knockback.
