With A Snap is an Original Flavor Avengers: Infinity War fanfiction created by ADdude.

Chapter 1 is a view of who besides the Avengers survived in this version of Earth. Chapters 2 to 45 are short stories focusing on different fictional worlds and how their populations deal with the dusting and its aftermath.

    • The Ben 10 Universe is a bit different from the prime universe. Word Of God confirms this is a parallel universe to that one.
