Consider the possibilities if someone else had become Nova! And find out what would have happened if Ghost Rider, Spider-Woman and Captain Marvel had remained villains! Stephen Strange becomes a disciple of Dormammu, Spider-Man stops the burglar before Uncle Ben is killed, and the Avengers fight the Kree/Skrull War without Rick Jones!

And what if the radioactive spider bit Aunt May?!
