Starro

Starro is a creature that was frozen for centuries, but was able to survive. It was examined in the Atlantean Science Center in Poseidonis, by a team led by Vulko.

The Assault of Atlantis was led by Black Manta on behalf of The Light, primarily to steal the creature from the Science Center. The plan was thwarted by Aqualad and Garth. Black Manta blew up the creature with a missile, but a piece survived the blast and began regenerating. This piece was taken to the surface world to be protected and studied.
