A sinuous, man-sized caterpillar undulates past, its thick body cloaked in bristly hairs that blaze through crimson, viridian, violet, gold—colors racing in rippling waves like liquid neon. Each hair quivers, ready to launch in a glittering, paralyzing storm.
A killerpillar is a giant, multicolored caterpillar native to the Fey Plane. As large as a person, killerpillars are covered with bristly hairs that constantly cycle through the entire spectrum of the rainbow, multiple colors running up and down its length much like strobe lights. However, though incredibly beautiful to behold, these creatures are also quite deadly. They fling the bristly hairs along their back at foes, injecting victims with a paralyzing compound that leaves them helpless.
Furthermore, creatures that merely look at their rainbow-hued hairs can be hypnotized, unable to move as they stare at the beauty of this deceptive assassin.
