When Superboy and Supergirl had temporarily to leave the Legion because of a kryptonite cloud that had surrounded the Earth, they asked the Legion to accept their choice of replacements. These were the disguised Star Boy (as 'Sir Prize') and Dream Girl (as 'Miss Terious'), both former Legionnaires.
Although some Legionnaires distrusted the disguised new members, they proved their worth and, once they revealed their true identities, were accepted back into the Legion as themselves once again.
