"The Hulk's Last Fight!"
The Hulk wanders North, and eventually transforms to the form of Bruce Banner, who chances to see the newspaper's headline, announcing that Reed Richards has discovered a cure for Banner's condition, which will prevent his ever becoming the Hulk again. He sets off for New York aboard a freight train.
At the Baxter Building, the members of the Fantastic Four ponder whether their publicity will reach Banner. General Ross still hunts the Hulk, despite his daughter's protests.
Banner makes his way to the Baxter Building, but the guard accosts him, and he transforms to the Hulk in the lobby, and the fight with the Fantastic Four commences. Richards manages to get his hands on his specially designed ray-gun, and downs the Hulk. (20 pages).
