Scisers[1][2] are clawed, amphibious predators found on Zebes.


Super Metroid[]

Scisers are three-eyed crustaceans found inhabiting the Crateria and Maridia regions of Zebes. They typically crawl continuously in a single direction at varying speeds (some as slowly as Zoomers, while others move quite rapidly) on small legs, with their large, curved claws perpetually raised.

There are three different Zebesian breeds: Scisers found in Crateria tend to have green carapaces and yellow eyes; those found in Maridia have green carapaces and red eyes; and those found in Maridia's depths have orange carapaces and green eyes.

Scisers are fairly weak, being one of the few enemies easily dispatched with the Grappling Beam. There are also withered, rotten corpses of Scisers in Draygon's chamber, which were presumably devoured by the Evirs and Draygon itself.

Metroid Fusion[]

After the planet's destruction, Scisers were grown on the Biologic Space Laboratories research station's Sector 1 and Sector 4. These specimens on the BSL station were blue and gold in color; it is unknown whether this coloration is natural. As Samus investigates Sector 4 following the X Parasites' breakout, these specimens will often become infected by passing X Parasites.

The physiology of X-infected Scisers differs radically from that of their hosts: Gone is the third eye, and their shells grow thicker and spikier, with enlarged claws capable of shooting arcing projectiles. Coloration also changes radically, with the carapaces turning grey, the legs blue and the enlarged claws purple. Said claws are also now capable of releasing arcing projectiles, which the X-infected Scisers do intermittently while moving in repetitive left-to-right patterns. They can be found crawling around on the floor, walls, or ceiling of Sector 4.

In rare cases, a golden Sciser will form from X Parasites. These are much stronger than their average counterparts, and their claws can block some of Samus' weaponry.

  • This species shares some similarities with the Tallon Crab, as they are both crustaceans which possess three eyes.
  • It is unknown as to why there were X-infected Scisers in Sector 1, given that Scisers were native to Zebes and Sector 1 replicated the environment of planet SR388.
  • Metroid Fusion: The Official Nintendo Player's Guide refers to Scisers as a "crablike creature".
  • In the internal data of Super Metroid, Sciser is known as Kani, a romanization of the Japanese word for crab (カニ?).
