Auroros

The Auroros is a pointy bird-like creature. It has a long and pointy beak, which it uses as a weapon. It dive-bombs from the air with its beak pointed straight at the ground. It causes massive damage to the players it hits, but gets stuck in the ground if it misses. Players can pluck them out of the ground and throw them at other enemies when this happens.

On a side note, Auroros' are one of three Subspace Army enemies to appear in at least one cutscene.
