Arachnoid

The Arachnoid-Strain Xenomorphs are a purple-and-black-hued brood which adapted significantly stronger leg muscles, allowing them to jump higher and move faster. They are assumed to be specialized variants of either the Warrior or Stalker Xenomorphs created through experimentation, in a similar way to both the Chrysalis and Razor Claw variants. Arachnoids are notable for lying curled up on the ground as they wait for foes.
