Reed has been holed up in his lab for days working on a probability engine which can be used to predict when villains are going to commit crimes before they commit them. Johnny sees the invention as the best way to select members for his baseball draft. Accidentally he triggers a malfunction and is shunted off into a series of alternate earths. He visits a world where Victor Von Doom is a hero and the Fantastic Four are villains, a world all the men are dead but the Femmetastic Four seek to reverse problem, a world where Spider-Man leads the Fantastic Four, and a world where things we normal except life was a musical. He is eventually sent home by Uatu who decided Johnny was too annoying to travel freely through alternate dimensions.

In this issue the "Marvel Adventures" world is designated as Earth-20051. This is the first indication of multiverse placement.
