Nightmare, the goopy, tentacled, skeleton King of Negativity, sat on his throne. He was also the leader of the Bad Sanses, a gang of villains who wreaked havoc of all kind. There was Error, his best friend of sorts, Cross, who wasn't very talkative, Dust, an absolute manic idiot, Horror, a talented chef with a big heart, and Killer, who was just unexplainably hyper and small for his age. The guys were all talking, except Cross, who hated talking, and Error.
