The Nemesis MXVII-10K is a Nerf blaster that was released in August of 2017 under the RIVAL series. It requires six "D" batteries or a Rechargeable Battery Pack to be operated.

It comes packaged with a Nemesis hopper, one hundred High-Impact Rounds, and instructions.


The Nemesis MXVII-10K is a fully automatic blaster. It features two tactical rails: a long rail on top of the hopper and a smaller one below the muzzle. On either end of the top rail are integrated, flip-up sights. The end of the blaster can act as a shoulder stock.

Unlike previous blasters, the Nemesis uses a large removable hopper with an agitator that advances the rounds into its flywheels. The feeding mechanism will not operate when the hopper is removed.


The Nemesis was originally leaked online on January 20, 2017. Five days later, it was officially announced on multiple news media sites.[1]

Color schemes

The Nemesis has been released with the following color schemes:

  • Team Red (red, black,white, and orange)
  • Team Blue (blue, black,white,and orange)

Reloading and firing

To reload the Nemesis, load up to one hundred High-Impact Round into the included hopper. Although the Nemesis can hold more than one hundred rounds in its hopper, to load more than one hundred is not recommended due to jamming.[2] Place the hopper into blaster's hopper receptacle.

To fire a round, hold down the acceleration trigger to rev up the flywheels. Hold down the firing trigger briefly to fire one round, or hold the trigger for automatic firing. It may take a moment for the flywheels to come to full speed; firing before that can reduce the blaster's range.


  • The Nemesis MXVII-10K is named after Nemesis, the Greek goddess who enacts vengeance on those who succumb to hubris (arrogance before the gods).
  • With its one hundred-round hopper, the Nemesis MXVII-10K has the third-highest ammunition capacity of any Nerf blaster in history, the second highest being the new Prometheus MXVIII-20K, with a capacity of two hundred rounds, and the highest being the N-Strike Elite Hail-Fire, which was advertised as having a 144-dart capacity and can hold up to 288 darts if used with sixteen eighteen dart clips held together by Flip Clips.
    • However, since the Hail-Fire is fed through the use of multiple clips, the Nemesis holds the distinction of the second-highest ammo capacity among single-fed blasters, the first most again being the Prometheus MXVIII-20K.
    • Along with that, it is also the second-highest-capacity RIVAL series blaster released by far.
  • The Nemesis is compatible with the Hera MXVII-1200's battery tray, meaning that it can potentially take "C" batteries instead of "D" ones.
  • It could be considered a successor to the Khaos MXVI-4000, since both feature full auto firing.
  • The Nemesis is the first Nerf blaster to use a hopper system. Only the aforementioned Prometheus also possesses this trait.
