Fantastic Four (1961) 175-A

"When Giants Walk the Sky!"

It's a clash of titans as the High Evolutionary battles Galactus with the fate of Counter-Earth in the balance. It is Galactus who wins the head-to-head battle, and Counter-Earth is now his to feed upon. Meanwhile, Sue lays dying on the last planet but her near sacrifice is not in vain as she is discovered by the civilization that inhabits the planet, but has masked their existence. The planet's leader agrees to sacrifice his entire planet and everyone on it in order to save Counter-Earth. Galactus leaves Counter-Earth and devours the new planet, but he finds out too late that the planet has its own powers and devolves Galactus until he is no more. Sue returns home safely with the lone survivor of the sacrificed planet, the Impossible Man.
