Galactus ends up giving the Fantastic Four an ultimatum, telling a pregnant Sue that he'll spare Earth if she gives up her powerful unborn child to him. The group declines his deal, which further angers Galactus, sending him on a vengeful mission to both destroy Earth and take Sue’s child.

If the goal for The Fantastic Four: First Steps was for Marvel to finally get the comic world's first family right, then the mission has finally been accomplished.
