Superboy departed from the Legion due to a villain's plot, and the book was renamed simply "The Legion of Super-Heroes" starting with issue #259 (January 1980). Editor Jack C. Harris hired Steve Ditko as guest artist on several issues, a decision which garnered a mixed reaction from the title's readership. Jimmy Janes became the regular artist in a lengthy tale by Conway (and later Roy Thomas) involving Ultra Boy's disappearance during a mission, and his long odyssey to rejoin the team. This story told the tale of the Legionnaire Reflecto (only glimpsed during the "Adult Legion" stories in "Adventure Comics"), featured villainy by the Time Trapper and Grimbor the Chainsman, and saw Superboy rejoin the team.
