What Color is Your Cleansuit?.In order to fulfill a contract with his brother, Dr. Venture hires Billy Quizboy, Pete White, and several dozen college interns to work on the Palaemon Project, an ionic ray shield for J.J.'s Gargantua-2. Venture must also deal with Dean's new "emo" persona, which changes when he meets intern Thalia. Later, Venture and friends discover that the ionic radiation emitted by the shield array has been mutating the interns; the scientists have become four-armed telepaths and the builders have become terrifying monsters, with both developing a taste for the flesh of Dr. Venture's unmutated personal servant interns. Gary, now "Sphinx Commander" after the rest of SPHINX has been reincorporated into O.S.I., begins to handle his new responsibilities. Billy must deal with old rival turned Guild-authorized archenemy Augustus St. Cloud, with his albino Asian henchman Pi Wai, who has not yet forgiven Billy for outbidding him on eBay. And elsewhere, the Monarch lives in denial of 21's defection while Dr. Mrs. the Monarch seeks a way to fight Venture's "army of mutant soldiers".
