Written by Paul Levitz and Keith Giffen, with art by Giffen and Steve Lightle this volume collects The Legion Of Super-Heroes #1-6 and its ground-breaking story that saw the Legion of Super-Villains reunite under the leadership of Lightning Lord.
The Legion of Super-Villains make a blood oath swearing they will each kill a Legionnaire.
Dream Girl, Shrinking Violet, and Starman fight Micro Lad on Ventura until he is teleported away. Colossal Boy and Chameleon Girl get an apartment together, and he is shocked to find that his mother Marte Allon has resigned as President. Radiation Roy kidnaps Light Lass on Winath. Mon-El and Ultra Boy are rebuilding Daxam when they hear of a Daxamite attacking Takron-Galtos. Ol-Vir releases the prisoners and recruits them to the Legion of Super-Villains.
Lightning Lord tries to convince his sister to denounce the Legion and join him in destroying them, whilst Dawnstar and Wildfire fail to stop Lazon, Magno Lad, and Titania from stealing fusion powerspheres.
Element Lad takes charge as new team-leader and organizes them against the threat from Legion HQ but Zymyr steals Earth’s protective shields with Radiation Roy, Sun Emperor, and Tyr.
Lightning Lad and his pregnant wife Saturn Girl nearly die trying to stop them, but the villains are called back by teleporter. Saturn Girl is taken back to Medicus One, where Doctor Gym’ll tells them she is in labour…
Can the Legion survive this all out attack?
