As General Skarr is once again annoyed by Billy, Hector Con Carne and Major Dr. Ghastly arrive in his house with the intention of luring him back to the recently relaunched Evil Con Carne world domination organization. Although initially refusing to rejoin, Skarr later accepts with the condition that Billy and the other neighbors be destroyed. After weeks of living together and preparations, Evil Con Carne's ultimate weapon is revealed to be an army of tanks that shoot giant rubber bands. In the end, their all-out attack over the neighborhood is foiled when Billy tricks Hector into shooting Skarr's garden and they get into a fight, causing Hector to get crushed by the one of the tanks. Note: This episode aired as a segment of The Grim Adventures of Billy & Mandy but it is technically the official series finale of Evil Con Carne.
