Incredible Hulk, The (1968 series) #450

Story 1: Hurray Hulk!
The Hulk is talking to Janis after his battle with the Thunderbolts when the army attacks. They jump out of there to Universal Studios California. But Janis is still worried about Hulk's temporary weakness against the Thunderbolts. Hulk is uncertain, but is trying to cover it up. In the meantime, Wildman highjacks a limo from the airport and is still being drawn to the Hulk by the voices in his head. When he finally arrives, the battle begins! It is quickly apparent that Wildman is a tricky opponent, with a wide variety of powers that seem oddly familiar. Something strange is happening... The Hulk finally manages to get in a good hit when a sudden rainbow light appears. Wildman's powers vanish, along with the voices in his head. Turning around, the Hulk sees... The Hulk!

Story 2: A Little Leeway
Doctor Strange is in his sanctum, peering into the Eye of Agamotto, when he is assaulted by green and white energy spheres. Following them, he finds the Hulk! The green sphere traps the Hulk briefly, but he quickly shatters it. The white sphere encircles him like an enery shield, repelling all contact. Doctor Strange takes astral form to enter the white sphere to investigate this mystery. Inside, Strange finds himself in an entirely different world, one in which the Hulk stands in the middle of a ruined city. His spirit seems to exist here physically, able to be touched and damaged just like flesh. Strange is saved by the sudden appearance of the Fantastic Four, and together they manage to restrain the Hulk. Their success is short-lived, but Strange realizes that the Hulk is somehow responsible for this alternate universe. His spirit is suddenly pulled back to the real world when the Hulk breaks free from the white sphere. He tells the Hulk that he must break his connection with the other universe before its energy destroys him and the world with it, but Hulk does not stay to listen.
