- "A huge swarm of four-legged spiders skittered in, electricity crackling at the end of their stinger tails."
- ―Narrator [src]
Scorpio-Spiders are a race of Visorak-like spiders with stinger tails. They were Mutran's attempt at creating an instant army for the Brotherhood.
Scorpio-spiders are four-legged insectoids with stinger tails and emerald-black coloration.
Scorpio-Spiders could create balls of electrical energy at the end of their tails and throw them at a target. Their stingers, similarly, created an electric shock upon contact. Their venom weakened a target to about half their previous strength, making it easier to capture, but the venom had to be directly delivered by their fangs.
Scorpio-Spiders are carnivorous, and they hunt their prey with pin-point accuracy.
Scorpio-Spiders make colony structures out of webbing which then house large numbers of the spiders.
They have been sighted everywhere. Their main concentration is at Crystal Island, but they are treated as normal Rahi everywhere else.
Burtok used them the take over Crystal Island and harass the Avenging Alliance. They also made enemies of the Crystal Raptors when they started taking Lightning Crystals and preventing the raptors from doing so. This made is easy for the Alliance to use the raptors as a strike force against the spiders.
When Burtok killed Jaykorax, he took the mutant Skakdi's talisman, thus gaining total control over the spiders. When Burtok was defeated, the spider army disbanded, and they were left at the mercy of angry and hungry Crystal Raptors.
- The Scorpio-Spiders are perhaps the longest-running coherent concept in the Altronia Continuity, persisting even from the early conception stages of the story.
