"Vite mes ami! We face a mystery stranger than the King Tut killer of Earth-66."
—Sherloque Wells[src]

Earth-66 was one of the many universes in the multiverse.


At some point, Harrison Sherloque Wells investigated a case in Earth-66 regarding the King Tut killer.[1]

Earth-66 was later destroyed by antimatter at the beginning of the Anti-Monitor Crisis.[2]

A new version of the universe was later created, when the Paragons and the Spectre created a new multiverse.[3]
