Earth-221

"I have entered into people's minds using this very technology. From the unfortunate comatose victims of the Summerholt Institute to, yes, Jervis Tetch himself, the Terrible Mad Hatter Killer from Earth-221."

—Harrison Sherloque Wells^[src]

Earth-221 was one of the many universes in the original multiverse. It was the home universe of Harrison Sherloque Wells.

History

Sherloque sent Renee Adler to Earth-221 to keep her safe from Cicada.^[1]

After Cicada was defeated on Earth-1, Sherloque decided to return home. He went to CC Jitters to get a drink, then noticed the door opening all by itself. Realizing that it was opening due to the meta-human Renee Adler, he smiled.^[2]

In 2019, Earth-221 was destroyed by antimatter during the Anti-Monitor Crisis.

Trivia

Sherloque implied that Thanksgiving doesn't exist on this Earth.^[4]
According to Sherloque, there are no Zambonis present on Earth-221. During the winter, ice is cleared manually with squeegees. Winter also lasts for eight months of the year.^[3]
- This explains Sherloque stating, "I thought your Earth would be colder" along with the overcoat he initially wore upon arriving on Earth-1.^[5]

Behind the scenes

Earth-221's designation is most likely a reference to 221B Baker Street, the London address of the fictional detective Sherlock Holmes.
