Omega Device

The Omega Device was a device invented by a blind inventor, used to momentarily disable a Dark One via a localized blast of delta-band noise. Exactly how it works remains unknown, as its blind inventor only described it once to a deaf person. Or so the legend goes. Fry used it to momentarily disable the Dark One. When activated the device unfolds into a spear like shape and immediately creates a small green pulse. Apparently, the Omega Device requires a power source.
