Ecco and the Vortex
The first Ecco the Dolphin serial begins when a strange force removes the life from Earth's seas, leaving Ecco to search for the other dolphins. His route through time and the oceans reveals the Vortex, an alien species using Earth as a food source. The six-part Return of Ecco the Dolphin resumes the conflict much later in the comic: the Asterite, a mysterious underwater ally, helps him reach the Vortex's world and rescue those taken. These two separated serials make Ecco one of the clearest examples of a Sega game adaptation continuing its own story across the numbered run.
