Fantastic Four: The Animated Series #208

Poor Johnny Storm is still depress after his break-up with the Inhuman Crystal, but that depression soon goes away when he meets Frankie Raye, a superhuman with the same fire powers as his. Meanwhile, Terrax arrives at New York City and suddenly caused the entire island to rise in thin air. Terrax demands that the Fantastic Four defeat Galactus, and the team agrees. Later, they realized that Terrax betrayed Galactus and he lead him here so that Earth will be destroyed. Frankie's fate must be determined, whether she becomes Galctus's next herald so that Earth may be spared, or the world dies. Looks like Daniel Ketch and Thor's intervention may be useless here.

Note: This episode is a direct adaptation and combination of Fantastic Four Issues #242 until #244.
