Rhomann Dey and the Nova Corps catch up to the Guardians of the Galaxy at the time when they are pursuing J'son and the stolen Nova Centurian Helmet. Nova escapes where he managed to make it back to Earth only to be attacked at his school by J'son who discovered that he can't removed the helmet from Sam due to it being tied to his DNA. Following the the Guardians of the Galaxy and Nova's fight with J'son at Sam's school, Sam finds that J'son knows where he lives and finds J'son confronting his mother and little sister Kaylen posing as a police officer. The Guardians of the Galaxy must help Sam keep his family safe from J'son.
Marvel's Guardians of the Galaxy features themes of redemption and the importance of friendships and family told through a series of riveting sequential story arcs. The series follows the newly-formed team who finds a strange artifact keyed only to the DNA of Peter Quill. Upon opening it, Quill unleashes a treasure map leading to a powerful weapon known as the Cosmic Seed which is capable of giving birth to the next universe.
It's up to the Guardians to find, protect and ultimately destroy the Cosmic Seed in order to keep it out of the hands of those who would abuse its power, from galactic big boss Thanos, to the conniving brothers the Collector and the Grandmaster, to a resurrected Ronan, to the ultimate trickster, Loki, in order to save the universe.
