The Prometheus MXVIII-20K is an upcoming Nerf blaster that will be released under the RIVAL series.[1]

It comes packaged with two-hundred High-Impact Rounds.


The Prometheus is similar to the Nemesis MXVII-10K, as both are fully automatic hopper-fed blasters, meaning that it could generally be regarded as the successor to the Nemesis MXVII-10K. It features a carry handle on the front, and a sling mount underneath the barrel. Due to the lack of information, it is unknown if the hopper is removable. The trigger area is located on another carry handle in the back, where another sling mount can be found.

Currently, it is only seen as white, suggesting the current version is a prototype. It is unknown if it will be released under the RIVAL series or the Phantom Corps sub-series.


The Prometheus was originally leaked in summer of 2017, along with other Phantom Corps blasters such as the Hades XVIII-6000, the Helios XVIII-700, and the Kronos XVIII-500. Its name was originally unknown, a distributor website unintentionally revealed its name.[2]

Reloading and firing

Pull the trigger to fire a High-Impact Round.


  • The Prometheus MXVIII-20K is named after Prometheus, a Titan, culture hero, and trickster figure who is credited with the creation of man from clay, and who defies the gods and gives fire to humanity.
    • Zeus, king of the Olympian gods who the Zeus MXV-1200 was named after, sentenced Prometheus to eternal torment for his transgression. The immortal Prometheus was bound to a rock, where each day an eagle, the emblem of Zeus, was sent to feed on his liver, which would then grow back to be eaten again the next day.
  • The Prometheus has the highest stock capacity of any Nerf blaster. The Prometheus also has the second highest capable capacity, as the Hail-Fire is the highest capable capacity, with drums and Eighteen dart clips.
