What If? Beast and Thing had continued to mutate. These stories rarely end well, but Thing’s does. Thing ends up cured, and Alicia’s blindness gets cured as well.
Not so for Beast, who ends up savage. He crawls back to Professor X for help, who dumps him in the savage land.
And a third story, not on the cover, has Galactus freeing Norrin Ladd from being Silver Surfer.
