"From Earth-12, the holder of four PhDs and the author of the book, "Everything is Meaningless, so Why Did i Buy This Book?", I give you ... Herr Harrison Wolfgang Wells."
Harry Wells introduces a resident of Earth-12 to Cisco Ramon.[src]

Earth-12 was one of the many universes in the original multiverse. It was the home universe of Harrison Wolfgang Wells, an ally of Team Flash and member of the Council of Wells, as well as the Green Lantern Corps.


At some point, Harrison Wolfgang Wells wrote and published a book Everything is Meaningless, so Why Did i Buy This Book?.

Felicity Smoak, Ray Terrill, and Nyssa al Ghul were transported to Oa by the Phantom Stranger, where Felicity pleaded the Guardians to let her read the Book of Oa. As shadow demons approached, Ganthet allowed her to do so, as the Green Lantern Corps fended the shadow demons off.[1]

This Earth was later destroyed by an anti-matter wave during the Anti-Monitor Crisis.

Behind the scenes

  • In the DC comics, Earth-12 was originally a parodic world home to a team of "heroes" known as the Inferior Five and it was half of Earth-B, the other half being Earth Thirty-Two. After Crisis on Infinite Earths, it was changed to be the universe where the DC Animated Universe series of cartoons took place, with several Batman Beyond comics serving as a companion/continuation of that series. Also, there was an Earth Negative Twelve in the Dark Multiverse, in which Batman killed Ares and took his power, went insane and became "The Merciless".
