This was the beginning of John Byrne's "fantastic" run on Marvel's flagship series. His first issue brought back long time FF foe Diablo with, what else, a plan to exact revenge on the FF by mystically bringing to life elemental statues he had stolen and using them to get rid of the Fantastic Four. He cleverly sent each of the four elementals (earth, water, wind and fire) after a member of the FF the most unsuited to handle its' particular attack. Still known as "The Invisible Girl" at this point, Sue Richards was attacked by a monstrous behemoth made of earth (which Sue even said reminded her of The Thing) which tried encasing her in a earthen tomb. Ben Grimm was attacked by a water elemental that surrounded The Thing with a watery cocoon, thus depriving him of oxygen.
