The regenerator is a common enemy found in the Aurelian Depths.
The Regenerator is a red jellyfish capable of quickly regenerating lost limbs. It has 3 tentacles that it uses for propulsion and defense and its large, somewhat piramidal bell is thick and transparent, allowing to the player to see the liquids inside its body.
The Regenerator will chase the submarine and latch onto it once it's near enough, disabling shields and penetrating the hull with its tentacles, creating three holes sticking its tentacles inside through them, which need to be destroyed for it to release the submarine. Once its limbs are destroyed, its bell will float around and, if not killed, will regenerate its tentacles and attack the submarine once again.
- The Regenerator can be seen in most of the art from the Squishy Update.
