Fantastic Four #16 (1963)

Fantastic Four #16 is a true classic, and one of the most memorable issues from the early years of Marvel Comics. The issue starts off with the Human Torch rushing to the Fantastic Four, only to find the team shrunk down to a tiny size. They quickly grow back to full size, but none of them has any explanation for what has happened. As they're trying to figure things out, a mysterious voice speaks to them, warning that they're helpless before him, and that this is only the beginning.

The team soon realizes that they've all been shrinking down over the past few days, but didn't say anything because they didn't want to sound ridiculous. Mr. Fantastic suggests that they seek out the superhero Ant-Man for help, but the rest of the team is skeptical that he even exists. Nevertheless, Mr. Fantastic manages to call on Ant-Man, who arrives and gives them two drops of fluid - one that will cause them to shrink, and the other that will make them grow.

The story takes a dramatic turn when a mysterious voice warns the Fantastic Four about Doctor Doom's evil plan. The team finds themselves shrunk down once more, this time ending up in an entirely different world where they confront Doom himself. The villain has been using his advanced technology to conquer the planet and enslave its inhabitants, and he plans to do the same with the Fantastic Four.

The Fantastic Four eventually manage to escape from their underwater prison and return to the normal world. With Ant-Man's help, they defeat Doctor Doom and save the day.
