According to the comic book, Marvin went on to study at Ivy University, the fictional university where fellow superhero the Atom worked as a professor. Wendy moved to Paradise Island to attend an Amazon university and continue her training. Wendy and Marvin appeared again in a later issue of the "Super Friends" comic to aid the Wonder Twins, posing as Zan's and Jayna's human disguises, "John" and "Joanna", to fool a criminal who had deduced the Wonder Twins' secret identities and tried to use them to learn Batman's.
