"The Skrull Takes a Slave!" Part 1 of 4. Script by Stan Lee. Pencils by Jack Kirby. Inks by Joe Sinnott.

The Fantastic Four's cataclysmic clash with the Mole Man is over! But danger is still lurking inside the Mole Man's house! When Reed, Ben, and Johnny try to question the Mole Man, the subterranean super-villain escapes and flees to his sub-surface home! However, the fabulous foursome (plus Crystal) have had enough of the Mole Man on this day and elect not to pursue him further. Meanwhile, a sinister skrull lands in New York! What is the alien's malevolent mission? Here's a hint: It involves the blue-eyed idol of millions and a galaxy far, far away! 

Note: The Mole Man returns in Incredible Hulk #127 and battles the FF again in Fantastic Four #127.
