The Superior Spider-Man's unusual alliance with the Sinister Six takes a dangerous turn when the reformed Masters of Evil enter the picture.
While Otto Octavius continues controlling five members of the Sinister Six and forcing them to serve as his personal superhero team, Lightmaster launches a plan to steal the powerful Quantum Particle Engine from Parker Industries.
Spider-Man, the Superior Six, and the new hero Sun Girl are drawn into a massive confrontation with the Masters of Evil. During the battle, Sun Girl's secret connection to Lightmaster is revealed: he is actually her father!
As the fight intensifies, Otto's control over the Superior Six begins to weaken, threatening to turn his carefully constructed team against him. With enemies closing in and his plans falling apart, the Superior Spider-Man discovers that controlling villains is much harder than he expected.
