Waver

A self-dependent creature, Wavers will not usually group together in a pack to attack prey, an exception being a large, weakened creature. Wavers are hunter-scavengers, returning to nature that which is no longer needed, but will attack living creatures if the search for food becomes futile. These enemies constantly arc up and down when flying, creating a "wave" type pattern. It is unknown why they do this, perhaps to increase the chances of catching small insects flying through the air. It is believed that the Chozo created the Wave Beam to celebrate the Waver as a holy creature.
