When Captain Marvel's enemies Black Adam and Dr Sivana team up, Marvel enlists Batman to aid him.

Led by Faceless Hunter, the Starro Invasion comes on full swing. Only Batman and a handful of unlikely heroes remain uninfected to thwart the alien parasites and their mind-controlled hosts before all of Earth is sucked dry.

Star Conqueror may be defeated, but Faceless Hunter is not! The alien warrior manipulates B'Wana Beast, forcing him to combine thetiny starros into one massive beast he plans to use to destroy the planet! But Batman has his own back-up - the Metal Men!

Batman joins forces with Captain Marvel, Mary Marvel, and Captain Marvel Jr. to take on Dr. Sivana and his Monster Society of Evil. However, the villains gain the most likely of newcomers -- the wormlike Mr. Mind.
