But all is not lost, Toxie, with his newfound power, has joined forces with Major Disaster, Nozone, Headbanger, and Junkyard to form the Toxic Crusaders. No, not the ultimate heavy metal band, you moron! This motley crew is sworn to defend Tromaville and the rest of the U.S. from the polluting ways of Dr. Killemoff and his Radiation Rangers! It won't be any easy mop up operation, but with your help the Toxic Crusaders are sure to make a clean sweep of the six levels of sludge, slime, goop and grime, while washing Killemoff and his filthy friends off the face of the earth forever!
