Baron Silas Greenback is a villain and character in the TV series Danger Mouse.


Greenback is a anthropomorphized toad who is Danger Mouse's deadly archnemesis.

His main goal is world domination and destroying Danger Mouse whom he calls "White Wonder" or "Wretched Rodent". He has several bases throughout the world where he conducts his operations with his pet caterpillar Nero and his two henchcrows Stiletto and Leatherhead.

His most common mode of transportation is the Frog's Head Flyer, a machine that can hover in the air anywhere at anytime.

Most of the time he sits at a control panel staring at a large screen either speaking to Danger Mouse, controlling his high tech weaponry or watching the progress of his latest schemes or he occasionally walks leaning on a purple topped cane.

His evil schemes have included destroying the world with a deadly sound ray, concreting over the entire planet, and melting the polar ice caps. Some of them have almost succeeded, although Danger Mouse always manages to foil his plans, which make the maniacal amphibian even more determined to destroy DM and rule the world.


Greenback has a hoarse voice and a wicked laugh. He is also quick to get angry when his schemes go wrong or his henchcrows mess up. He has a "Whack Box" in his hideout or on board the Frog Head Flyer that he uses to hit Stiletto when he gets something wrong or just simply just hits him with his cane.
