Fantastic Four #16
CRASH LANDING! The Fantastic Four have crash-landed on a far-off world and have been repairing their spaceship for weeks as they blend in with the aliens who live there, trying to keep a low profile. But when an unexpected discovery - shared with the best of intentions - leads to chaos, only the Fantastic Four can stop an entire world from sliding into a destruction of their own creation! This won't be easy- and it may not even be possible. Because to save this world...the Fantastic Four must die!
