If you could assemble an 850-page omnibus of your favorite "End of the World!" Marvel Universe stories (using no more than three What If...? tales, 'cause a person could likely fill the whole collection with just What If...? stories), what would you include?

My omnibus would have:

Punisher Kills the Marvel Universe (1995)
X-Men: Days of Future Past
What If...? The X-Men Lost Inferno
Hulk: Future Imperfect
Hulk: The End
Punisher: The End
The Last Avengers Story
New X-Men: Here Comes Tomorrow
Old Man Logan

Mine would have the equally-hypothetical story The Adventures of Franklin and Galactus.
