Scorpions are a class of predatory animals and beasts. Their main characteristic is the stinger on the end of their tails. Scorpions are inherently arthropods, and are often compared to spiders and crabs. There is believed to be a triangle rivalry between the three.
Scorpions are relatively useless when fighting other arthropods since their stingers are meant to pierce soft targets like mammals, and are useless against arthropod armor.
