The Veleek is an amorphous alien creature that resembles a cloud of dust, but can form blades and teeth to attack its prey with, as well as arms, wings, and even functioning eyes on a whim. It isn't strictly one creature, but billions of tiny insect-like flying creatures that act as one and can take on any shape they want. Individually, they're the size of a flea, with hundreds of wings, upturned "bowls" that act as antennae, and two catfish-like filaments stretching out beneath their bodies. These beings feed on energy, which they absorb by draining it from their victims using the filaments.
