Metroid Database Bestiary

Wavers, named appropriately after their flying pattern, tend to inhabit long corridors and areas where Samus has difficulty dodging them. They are difficult to attack because they can be rather unpredictable.

Missiles or Charge Beam shots can usually take them out with relative ease.

When Wavers run into a wall in a room and turn around to go in the opposite direction, they can sometimes go higher or lower instead of staying at the same general height. Using this notion coupled with the Ice Beam can help you sequence break and reach areas that you may have thought were previously unattainable.
