The dangerous cosmic fissure known as The Fault has ripped opened a
portal to the Marvel Universe, spilling out the demented forces of a
horrific mirror universe where there is no death and life prevails
unchecked - the Cancerverse! From this dark realm, the evil Lord
Mar-Vell - a twisted version of the legendary Captain Marvel - leads his
army to claim our universe for their own! Nova, the Silver Surfer,
Quasar, Gladiator and more of the greatest cosmic champions of the
Marvel Universal rise to stop them, but when even they cannot stop the
forces of the Cancerverse, the fate of the universe lies in the hands of
the cosmos' never-say-die underdogs, the Guardians of the Galaxy! Facing
a threat like none other, Star-Lord and company cook up an
all-or-nothing plan to bring their prisoner, the mad titan Thanos, into
the Cancerverse to unleash hell! With everything on the line, the fate
of the universe rests in the hands of one of Marvel's greatest villains!
