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. Philip J. 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.

Trivia

 * The word Omega means End, this may have reference to the fact it is used in assistance to destroy The Dark Ones, and appeared in the final movie, and originally, final episode.
