<P> Batman sets to work, constructing an elaborate filter to separate the mingled dust . Robin asks him whether it might be in the world's best interests for them to alter the dust samples, so that humans can no longer harm one another . In response, Batman says that they cannot do so, reminding Robin of the fate of the Penguin's henchmen and their tainted rehydration, and can only hope for people in general to learn to live together peacefully on their own . </P> <P> With the world watching, the Security Council is re-hydrated . All of the members are restored alive and well, but continue to squabble amongst themselves, totally oblivious of their surroundings, but each of them now speaks the language and displays the stereotypical mannerisms of a nation other than their own . Batman quietly expresses his sincere hope to Robin that this "mixing of minds" does more good than it does harm . The duo quietly leave United World Headquarters by climbing out of the window and descending on their batropes . </P> <Ul> <Li> Adam West as Bruce Wayne / Batman </Li> <Li> Burt Ward as Dick Grayson / Robin </Li> <Li> Lee Meriwether as Catwoman (Miss Kitka) </Li> <Li> Cesar Romero as The Joker </Li> <Li> Burgess Meredith as The Penguin </Li> <Li> Frank Gorshin as The Riddler </Li> <Li> Alan Napier as Alfred Pennyworth </Li> <Li> Neil Hamilton as Commissioner James Gordon </Li> <Li> Stafford Repp as Chief Miles O'Hara </Li> <Li> Madge Blake as Aunt Harriet Cooper </Li> <Li> Reginald Denny as Commodore Schmidlapp </Li> <Li> Milton Frome as Vice Admiral Fangschleister </Li> <Li> Gil Perkins as Bluebeard </Li> <Li> Dick Crockett as Morgan </Li> <Li> George Sawaya as Quetch </Li> <Li> Van Williams (uncredited voice) as President Lyndon B.
