Scrape is a salvage expert from the planet Blue Plunder and an adversary of Dr. Dometone. He rides around in the ocean and outer space in a ship that resembles a giant robo-electric eel.
While doing his work in salvage in the service of his superiors, Scrape was hired to mine a certain rock from Third Earth. In order to succeed, he attempted to drain all of Third Earths' oceans, not caring what would happen to those who lived on the planet. He soon came into conflict with the protector of Third Earths' Great Oceanic Plug, Dr. Dometone.
