Asterias, or Space Starfish, are creatures created by Metron for Stevonian war purposes. Asterias are used solely in space battles. Asterias latch onto passing enemy craft and self-destruct in a powerful explosion, and can also expel huge clouds of ink that will obscure an enemy's vision and block all enemy sensors, rendering them completly blind. And because the ink is liquid, the ink will splatter on the outside of the craft so that they will stay blind until they are either destroyed or the battle ends. Usually, Asterias will use a combination of these (ink, then self destruct)
- Asterias Forbesii is the scientific name for (Earth) Starfish.
