Weevoids were one-eyed purple scorpion-like creatures that disguised themselves as rocks, found only in in the regions of Magnus. They shot Weevoid toxin from their tails, which would trap whoever happened to get caught in them. From up close, they used their tails and pincers to melee the heroes. They could also roll around in a rock from that was not harmed by weapons. According to Spog they were not native to Magnus.
