A Mochtroid.

Mochtroids are an enemy type native to Zebes in Super Metroid, which are weaker versions of Larva Metroids. These creatures are the result of the Space Pirates' failed attempts of cloning the last Metroid stolen from the Ceres Space Colony. Mochtroids were only encountered in a sub-aquatic Pirate outpost in Maridia.

A Mochtroid is far weaker than any type of Metroid encountered in Samus' previous missions, as its membrane is extremely flaccid and offers poor protection; housed within it is a single minuscule nucleus. Contrary to a Larva Metroid's fangs which are attached to a mass of muscle tissue underneath its numerous and massive nuclei, a Mochtroid's fangs are directly linked to its nucleus without featuring any such tissue in between.

Mochtroids can drain life energy by latching onto their prey like their ordinary counterpart, but they do not possess the powerful grip of the former; as a result, Samus can easily remove a latched Mochtroid with quick movements. She can destroy these failed clones with ease, even without resorting to the Ice Beam or Missiles.

Possible homageEdit


First Hunt

In Metroid Prime Hunters: First Hunt, Samus trains in several arenas by battling against various holograms. Some of these bear an extremely similar appearance to Mochtroids, but behave quite differently.

Though never given an official name, the description of Survivor Mode describes them and other types of holograms collectively as Xenomorphs.


  • It is unknown why Mochtroids were only encountered in Maridia. It is quite possible that the Space Pirates "dumped" them in Maridia when they were deemed failures.
    • Beta footage of Super Metroid shows that Larva Metroids were initially going to be present in Maridia instead of Mochtroids.[1]
  • Considering their crippling defeats during the Phazon crisis, the loss of one of their homeworlds, along with the eradication of Metroids on SR388, the Pirates were possibly forced into a last stand scenario. Ideally, they would want to create as many Metroids as possible in a shorter time period, thus explaining their reason for resorting to not only beta-ray usage, but also to an unspecified cloning procedure, the latter of which led to the creation of Mochtroids.
  • The Super Metroid Nintendo Player's Guide suggests Mochtroids are young Metroids that never matured. Mochtroids may be a mutated stage found between Infant Metroids and Larval Metroids.
  • Some Metroids featured in Samus and Joey as a flashback are erroneously featured with a single nucleus, making them slightly resemble Mochtroids. [2]
  • Their name is a pun on the word "mock-up", making them "mock Metroids".
  • Their appearance is somewhat similar to a Phazon Metroid, as they have similarly shaped bodies and talons.
  • Mochtroids are mentioned in the Metroid Trophy description in Super Smash Bros. Melee: "Mochtroids, which look like Metroids, are weaker, with fewer internal nuclei.".
  • Mochtroids are extremely vulnerable to the Grapple Beam, as a single Grapple Beam shot can kill it. Although it is unclear as to why, a possible explanation would be that their weak membranes are vulnerable to electricity or physical stress.
