Target Earth


Earth-Forty is the official name of the second oldest official alternate reality of DC comics.[1]

See the DC Database entry on Earth-Forty for more details.


Earth-Forty is an alternate universe, first described in Crisis on Infinite Earths: The Compendium (Nov., 2005)

Several Silver Age stories/comics were retconned in The Compendium to Earth-Forty. Theses stories include:

  • Adventure Comics Vol 1 120
  • Batman Vol 1 32, 131, 135, 145, 159, 163
  • Batman: The Dailies 1–3
  • Batman: The Sunday Classics
  • The Legend of Wonder Woman 1–4
  • Thrill Comics #1 (ashcan)
  • Superman Vol 1 46
  • Wonder Woman Vol 1 50, 156, 159, 165, 168


Earth-Forty's first hero was Superboy though he was raised and worked out of Metropolis rather then Smallville.[2]

In 1940 Billy Batson gained superpowers and took up the name Captain Thunder.[3]

During the 1940's Batman, Superman, and Wonder Woman all had adventures during WWII.

Bruce Wayne retired by the mid 1960's to make way for a new Batman and Robin Team. During this time he married Batwoman (Katherine Kane) and eventually retired passing the mantel of the Batman to his son Bruce Wayne, Jr.


  • Crisis on Infinite Earths: The Compendium lists entire issues rather than specific stories, leaving the question if any non contradictory stories in those issues occurred on Earth-One, Earth-Forty, or both.
  • The Compendium lists Thrill Comics, #1 (1940) as happening on Earth-Forty but doesn't count it as a first appearance (possibly because it was an ashcan comic)
  • The Compendium also doesn't count the 1943 Batman newspaper strip as a first appearance of Earth-Forty either (possibly because it wasn't an actual comic book).
  • The Crisis on Infinite Earths: The Compendium stated this was "revealed as a distinct parallel Earth in The Kingdom, #2" making this reality part of hypertime.
  • Queen Hippolyta is depicted as a blond in The Legend of Wonder Woman, #1–4 rather than having brown hair as on Earth-Two.
  • The Essential Wonder Woman Encyclopedia (2010) doesn't list Earth-Forty and assigns the "Golden Age" Wonder Woman stories to Earth-One resulting in those stories happening with variation on all three Earths.
  • If one counts Thrill Comics, #1 (1940) as Earth-Forty's true first appearance and Convergence #0's implication that Earth-Two didn't appear until The Flash, #123 then it is one of the three oldest alternate realities officially identified (the other two are Earth-Two-A and Earth-Quality). In any case Earth-Forty is the oldest official hypertime reality.


  1. Earth-Forty's first appearance was in the ashcan comic Thrill Comics #1 (1940) but this is beaten by Earth-Quality which goes all the way back to 1937.
  2. Superman Vol 1 #46
  3. Thrill Comics #1 (1940)
