Paradise X
Volume 1

In Earth X, Captain America, the Fantastic Four, Thor, the Hulk and the X-Men discovered that their purpose - and the meaning of all super heroes and mutated people in the universe -- was nothing more than to protect their host planet, in this case Earth, from outside invasion. They learned super heroes are merely biological antibodies to protect a growing embryo within the Earth. An embryo for the Celestial race: This is the way these Gods fought back -- only to cause a terrible ecological imbalance, a rift at its core that in time would wipe out all life on the planet. In Universe X, Captain Marvel was reborn on Earth years after his death.
