The Silver Surfer roams the universe in search of a planet for Galactus to consume. He spots the Kryptonian star system with two planets worthy of Galactus' consumption. Galactus immediately consumes the first planet with the aid of his worldship and his herald.
Galactus decides to consume Krypton next.
The Kryptonians have 6hrs prep time, because they detect Galactus consuming the other suitable planet in the Kryptonian star system first. The Kryptonians summon Superman, Superman Prime, and Silver Age Superman to join all Kryptonians in an attempt to stop Galactus.
The Kryptonian star is now yellow.
Can the combined forces of Krypton save the planet?!
