Evil the Cat
Evil the Catwas the feline ruler of the planet Heck. Evil's ultimate goal is to destroy the universe. He has made at least two attempts to do this.
The first was when he stole Earthworm Jim's Fuzzy Wuzzy's Funny Animal Pop-Up Book, to gain access to history's biggest printer's error, the Secret of Ultimate Destruction. The Secret was to get all the Reeking Beasts to see a fondue fork. He was foiled by Earthworm Jim. His second attempt was when he discovered that the universe was a big snow-globe, and he decided to shatter it, but was forced out temporarily.
When not attempting to destroy the universe, Evil works day and night to make the world a more horrible place- from inventing disgusting meals like liver and onions to creating impossible homework assignments to make innocent children suffer. He also spends a lot of time worshipping at the Altar of Vileness (also called watching television), and plotting new ways to spread his evil. Evil the Cat is quite a guy.
