The origins of the Scavenger remain one of the mysteries of the seven seas. He appeared to menace Aquaman and Aqualad in the depths of the ocean in an attempt to find the "Time decelarator" - an ancient device created by an alien civilisation.

Without the usual posturing or boasting of costumed villains, Scavenger went after his goal without explanation of his unusual motif and advanced scientific equipment.

Aquaman was able to destroy Scavenger's heavily armed Scorpion ship, but not before Scavenger gained possession of the decelerator. His prize, however. only suceeded in sending him on a seemingly reverse tgrip through time, deveolving him into an infant and then nothing.

The decelerator sent Scavenger into a timeless limbo from which it took him years to escape. Once he did so, he had only one thing in mind - revenge on Aquaman.
