Scrillin

The Scrillin were a Rahi-like species located primarily in the desert outskirts of Koya Nui.

Anatomy
Scrillin are four legged insect-like creatures with two arms that end in a long, barbed scythe. They have an hourglass shaped body, where the body is thick at the top and becomes thinner as it approaches the middle before thickening again. Their upper body is mostly hollow, with a silver ribcage-like exoskeleton protecting their vital organs.

Scrillin have clawed feet, and the scythes on their arms secrete a deadly poison that causes the affected areas of the body to completely shut down. Most Scrillin have large mandibles on their heads that surround their short fangs. Young Scrillin have four small eyes, but as they age the eyes merge and become a pair of large red eyes.

Roles
At birth, a Scrillin's role in the nest is pre-determined based on specific traits it possesses.

Warrior/Worker
The most common types of Scrillin, these are most easily recognized by their tan exoskeleton and the length of their legs. Warrior and Worker Scrillin are the most heavily armored but are much slower than Stealth Scrillin. They are most often seen defending the nest or searching for food.

Stealth
Stealth Scrillin are a rare type of Scrillin that can be recognized by their thin black exoskeleton and glowing green patterns on their scythes and faces. Stealth Scrillin, as the name implies, are the fastest and stealthiest Scrillin and serve to infiltrate enemy nests and relay information to the Queen. Their scythes do not secrete poison.

Queen
The Scrillin Queen is the rarest type of Scrillin, and only one can be found in a nest. Their exoskeleton is a pale white with slight transparency, allowing their red veins to be seen. The Scrillin Queen have the strongest poison and must remain in the nest, as it is responsible for the composition of the nest. If a Scrillin Queen dies, all the Scrillin of that nest will perish with it.

Story
Throughout much of the story of the Toa Koya, the Scrillin have merely served as a minor inconvenience from time to time, and it is only after the destruction of the Mask of Creation that the Scrillin serve an important role. Because of the imbalance caused by the Mask's destruction, many Scrillin mutated into Jetbugs and began rampaging in the cities, forcing the Toa to defend them. One Scrillin in particular was directly exposed to Creation Energy and alongside the Toa Koya and Darius, it was transformed to have Toa-like powers and began calling itself Wheua. Wheua attacked Fanua and Goll in the desert, but after being outsmarted and defeated, realized that the fate of Koya Nui was at stake and joined Fanua on his journey. Wheua, alongside the majority of the Scrillin, was killed when Koya Nui sunk into the ocean.
