Doctor Dometone

Doctor Dometone is one of Third Earth’s great thinkers, scientists and gentlemen. He is the chief protector of the Great Oceanic Plug (a massive engineering project built to seal a crack in the ocean floor to prevent the planet's oceans from flooding its core). He is a little man but very chivalrous, and a skilled pilot of Hercules (aka "Herky"), a giant frog-shaped robot used to guard the sea floor. He also had another its name was Samson, but it was destroyed, which saddened the doctor greatly. He refers to these machines as his children.
