"Set the Controls for the Heart of the Sun!"
A far-off civil war rages on as brother fights against brother but Umbra has an advantage, he has a suit of battle armor that siphons off power from a sun. Meanwhile back on Earth, our sun is losing energy and the Fantastic Four spring into action to save our solar system. Reed creates a device that will cut the siphon effect on our sun but as he activates his device, Umbra's armor malfunctions and causes the battling brothers to be combined into one creature. Back on Earth, the FF start their descent to come back home but their craft is badly damaged and it is up to Ben to get them home safely.
