Fantastic Four #20

THE DARK FOREST, PART TWO! The Fantastic Four have been attacked by aliens that are intent on their extermination...and these creatures are so powerful that our heroes can't fight back with any hope of victory. Their only chance is to try to communicate with them, to plead for mercy. But with both language and dimensional barriers, there may not be any hope...unless Johnny Storm can find a way to save everyone. The Fantastic Four face their most mind-bending challenge yet - and it's one that nobody else in the universe has been able to crack!
