"I was trained in the art of escape by Thaddeus Brown from Earth-51."

Earth-51 was one of the many universes in the multiverse.


At some point, Sherloque Wells was trained in the art of escape by Thaddeus Brown.[1]

This Earth was destroyed during the Anti-Monitor Crisis. It is unknown if this Earth was restored following the recreation of the multiverse.

Behind the scenes

  • In the post-Flashpoint continuity of the comics, Earth-51 is home several of the creations of writer and artist Jack Kirby that he authored while working at DC, namely OMAC and Kamandi, as well as versions of the characters from Kirby's Fourth World saga. Thaddeus Brown being an inhabitant of Earth-51 is likely a reference to this, as Brown was a Kirby creation and debuted in Kirby's Mister Miracle series.
    • Prior to Crisis on Infinite Earths, an extremely similar world known as Earth-AD was home to Kamandi and OMAC.
