Baron Silas Greenback: If it is difficult to dig out the facts on Dangermouse, it has proved downright dangerous to attempt to learn anything about Baron Silas Greenback. What he is, is common knowledge. At the mention of his name, tyrants tremble, strong men go pale and hard-boiled eggs turn to jelly.

But such is his power that no computer holds a single fact on him or his origins. He pays no income tax - who would dare collect it? He drives without a drivers license, shoots without a gun permit and keeps a pet caterpillar without a pet caterpillar license.

Nero: Right hand caterpillar of Baron Silas Greenback. Author of the best-selling guide to an insect-dominated society: "The Pest Decides". Nero comes from a long line of Champion Caterpillar at Tufts. The species, CREEPIO NASTISSIMUS, is noted for its evil intelligence, its loyalty to criminal geniuses and its cunning attempts to overthrow all that is good. At an early age Nero sold his own moth-er to a butterfly farm.

In 1979 a top level enquiry was launched into the mysterious disappearance of valuable roses from Colonel K`s garden in Chorleywood. All the evidence pointed to the rosenap being the job of an eight-man gang. Traces of white hair and mysterious semi-circular bite marks on the leaves made Nero a prime suspect. The eight separate sets of footprints, however, clearly eliminated him from the inquiries (since Nero presumably doesn`t have any feet).

It was not until early 1981 that DM was able to penetrate Greenback`s hideout by ingeniously allowing himself to be frozen into a block of blackcurrant-flavored ice. It was when Nero opened the door of the fridge to have a quick lick that DM was able to solve the mystery. Twenty-four hours later DM was explaining to Colonel K: "N-N-Nero, sir! Th-th-that`s why we n-never kn-kn-kn-knew he had s-s-s-sixteen feet! He w-w-w-wears eight p-p-pairs of m-m-m-moon boots - w-w-white furry..."

Stiletto: Nasaccio Mafiosa Cornetto, his real name, was born in the little walled Italian town of Semolina di Budino. "Rigoletto!" exclaimed his mother as the midwife pressed him into her arms, "but he is-a beautiful! Look Juan!" (His father was the famous Italian lawyer `Just` Juan Cornetto.) "Look! He has the handsome black feathers of a crow and the mouth of a jackdaw!" "OK!" said Papa. "If you say so!" And taking the infant, he hurled him into the garden. "Osso bucco!" screamed Mrs. C. "I said the 'feathers of a crow and the mouth of a jackdaw' - not 'throw him out of the back door!'"

Meanwhile, as the infant Stiletto was lying howling among the spaghetti bushes, a pair of wolves called Ron Millar and Remould passed by and lobbed the cheeping infant back into the house by way of the letter box. It was then that Stiletto decided to devote his days to the devious double dealing and disgrace of a desperado. Soon after these events, he was spotted by one of Greenback's scouts as he stole babies' rattles in the Piazza di San Marco and was recruited into Greenback's organization.

Greenback realized, as soon as Nasaccio signed on the crooked dotted line, that he had a right-hand man worthy of his evil. He was, as the Baron said, "One of the sharpest little heels the world has ever seen - we shall call him Stiletto!"

Count Duckula: Count Duckula is a vegetarian starstruck criminal vampire. He'll do anything to get on camera and gain his own television show...and he eventually did get his own show!
