Baron Silas Greenback is an evil toad out to rule the world, and the main enemy of Danger Mouse.
Baron Greenback is a round toad, with a round face, broad shoulders, thin arms, and even thinner legs. He wears a beige suit and purple tie. His pet, Nero is considered higher than his hench-crow stiletto!
- Edward Kelsey apparently based Greenback's voice on a farmer he had a disagreement with!
- The Baron stops the world from spinning in the original series season one episode 10, Ice Station Camel. However, he also attempts to stop the world from spinning in the reboot series in season one's 8th episode The Other Day the Earth Stood Still.
- In the pilot episode, he was called Baron Greenteeth.
