Marvel Comics will unleash a terrible secret from Star-Lord's past in writer Brian Michael Bendis and artist Ed McGuinness' Guardians of the Galaxy #19. With the truth revealed, none of the Guardians will be able to follows orders from their leader ever again.

In the Marvel Universe, there was a period of time where Peter Quill, also known as Star-Lord, was missing. While the rest of the Guardians of the Galaxy thought their space leader was dead, Star-Lord was actually stranded in the Cancerverse, alongside Thanos and Richard Rider, the former Nova. Though references have been made, Thanos and Star-Lord have remained silent about what actually happened in the Cancerverse.

All is finally revealed in Guardians of the Galaxy #18. Fans will be asking themselves, why is Nova siding with Thanos?

Secrets are finally revealed in the Original Sin tie-in, Guardians of the Galaxy #19. In the crossover event, Original Sin, someone has murdered The Watcher and gouged out his all-seeing eyes. The Watcher's eyes have seen every shocking secret committed by the major Marvel characters. From Marvel's official Twitter, check out McGuinness' cover to Guardians of the Galaxy #19:
