Nefarious Villains are recurring enemies in Peanut's Spot (Superdog) comics, and a few times in Dimension Prime.
Dalmatian[]
The first criminal to appear in the comics. He was a "not smart" Dalmation who tried robbing a bank, but was stopped by Spot.
Nefarious Villain[]
A recurring brown dog who is commonly seen wearing a dress and seemingly wear sunglasses or blinders. Debuting when he put together a team of all the crime lords, he disguised himself as an "orphan" and has stayed that way ever since. He first appeared in The Further Adventures of Spot.
The Cyborg[]
Appeared in disguise along with "Nefarious Villain", he revealed himself to be none other than The Cyborg, Spot (Superdog)'s arch-nemesis. He first appeared in The Further Adventures of Spot. In The Identity Of Spot it was revealed he is really Jim-Jim in disguise, but it is unknown if he was really Jim-Jim all along or was just disguised as him.
