"Magpie Complex." An archcriminal stalks Legion Headquarters--while Sun Boy's in for a big surprise! Written by Paul Levitz and Mindy Newell, with art by Dan Jurgens and Karl Kesel. (Notes: Pages 9 & 10 are a cutaway map of Legion HQ; Monitor and Lyla in pre-Crisis On Infinite Earths #1 cameo appearance (they also appear in #319).) Plus: The 8-page back-up tale "Triangle?"

Written by Paul Levitz and Mindy Newell, with art by Dan Jurgens and Karl Kesel. (Note: Cameos by Charles & Kitty Storm, who uncannily resemble Charles Xavier and Kitty Pryde.) Cover by Jurgens and Kesel.
