[Detective Conan] It Begins with Watching

Conan discovers that they've arrived in a mysterious movie theater.

The theater's creator, Doctor Strange, explains that the mad killer Deadpool used the Reality Stone to merge the 4869 universe, where he comes from, with the 086 universe, triggering a crisis that threatens to destroy the universe. To clean up the mess he made, Deadpool seeks help from Doctor Strange and Doctor Jean Grey.

Doctor Jean Grey will use the power of the Phoenix to help them. Her plan is to have them watch the 049 universe in this movie theater, created using the Space Stone and the Time Stone, and gradually bring about the merger as they learn more about the 049 universe.

And so, saving the world begins with watching a movie.

No chapters written in advance, updates whenever inspiration strikes.

Crossover, with a little The Lost Tomb.
