Hulk returns from space, and when he reverts to Bruce Banner, he finds he can remember things from his Hulk time more vividly than ever before. It turns out that the cumulative effect of Banner’s attempts to cure himself of being Hulk have given him the ability to become Hulk but keep his Banner consciousness. A bit of an underwhelming transformation.
In #272 and 273, he helps Sasquatch fight Wendigo. #273 ends that story and begins one with crop-eating aliens.
Hulk is a hero!
