Fantastic Four #118 (1972)

Johnny Storm has arrived in Terra Verde where he witnesses their local air force attacking the native peasants in the area. At first he thinks they are just practicing war games, but soon Johnny realizes the truth and comes to the citizens' aid by incapacitating the planes. One of the jets is able to sneak up behind him, but before Johnny is attacked the jet suddenly breaks apart. Johnny looks towards the cause of the destruction only to be shocked when he spots Crystal among the people down below. He rushes down to her side and kisses his long lost love. Crystal swats him away, and insists that she is the goddess Ixchel. "Ixchel" then warns him that if he hadn't aided in defeating her enemies any other would have suffered her wrath and if he should try such things again she wouldn't hesitate to make her anger known. When Johnny tries to press the issue, "Ixchel" uses her elemental powers to douse his flame then proceeds to leave with her followers. Meanwhile, Diablo has forced Lockjaw to teleport him into the palace of Terra Verde. After dispatching the guards, he confronts the ruler of the country, General Robles. Telling Robles that he intends to take over the country for his own ends, he teleports Robles back to the Mayan temple where he is stationed. There, they are attacked by the Human Torch who has made it to the temple before Crystal. Diablo tries to fight back, but the Torch's flame powers have grown stronger since their last encounter. When Crystal arrives shortly after their confrontation Diablo orders her to attack Johnny, but realizes that the potion that keeps her under his control is slowly starting to lose its effectiveness. Diablo changes his course of action by rushing into the temple to try and get more of the potion, however when he gets to the temple's entrance he finds that it is blocked by an invisible force field. This leads him to the conclusion that the rest of the Fantastic Four have arrived and upon looking towards the sky Diablo sees that they have flown to Terra Verde in their Pogo-Plane. Diablo orders his followers to attack, and, while the locals clash with Reed and Sue, Lockjaw teleports the Thing away. As the battle rages, Diablo is too late to reapply his potions, and the Mayan temple reverts back to its original ruined state. Crystal is freed from his control. With Diablo exposed as a fraud, the locals stop fighting. Inside the temple, Diablo attempts another potion to get revenge against his foes when he is suddenly attacked by General Robles, causing his potion to be knocked out of his hands. At that moment, Lockjaw and the Thing return, and the Fantastic Four head toward the temple. However, before they can get close, it is destroyed in a massive explosion. With Diablo seemingly dead and Crystal free, she is happily reunited with Johnny. The reunion is short-lived however as Crystal explains to Johnny that she cannot stay with him so long as Maximus rules the Inhuman throne and that she has to leave to help aid in the liberation of her homeland. Johnny is saddened by this but understands and tells Crystal that he will wait for her to return.
