The Kree Empire is knocked back on its heels when the Phalanx, a cybernetic race that converts hosts using a techno-organic virus, seizes control of Hala, the Kree homeworld. The person who accidentally brought the Phalanx right to the heart of the Kree Empire? Peter Quill, otherwise known as Star-Lord.
The remnants of the Kree are in utter disarray, their massive technologically advanced fleets totally susceptible to Phalanx control. Eager to make up for his genuine mistake (and without much choice), Star-Lord and a rag-tag team (Rocket, Groot, Gamora, Drax, and Mantis) are drafted into service to help turn the tide. Can a small group of poorly equipped mercenaries and misfits defeat the Phalanx before they consume the known universe?
Outgunned and outmatched, the Guardians of the Galaxy race to find anything or anyone who could hold the secret to stopping the Phalanx, a quest that will take them to the fringes of intergalactic civilization, and a shocking foe at the heart of the threat.
