The release of The New Adventures of Superboy #1 (January 1980) coincided with Superboy's (temporary) departure from the Legion in The Legion of Super-Heroes #259, as well as the one-shot Superboy Spectacular #1. Much as Superboy's debut in Adventure Comics depicts Clark celebrating his tenth birthday, New Adventures of Superboy #1 features Clark celebrating his sixteenth birthday and includes a flashback to Clark's first days as Superboy at the time of his eighth birthday.
