Justice League of America #82 (1970)

The Batman of Earth-Two is a parallel version of the DC Comics superhero, who was introduced after DC Comics created Earth-Two, a parallel world that was retroactively established as the home of characters whose adventures had been published in the Golden Age of comic books. This allowed creators to publish Batman comic books while being able to disregard Golden Age stories, solving an incongruity, as Batman had been published as a single ongoing incarnation since inception.

Batman of Earth-Two first appeared in Justice League of America #82 and was created by Dennis O'Neil and Dick Dillin.

The character history of the Earth-Two Batman accordingly adopts all of the earliest stories featuring the character from the 1930s and 1940s, while the adventures of the then-mainstream Silver Age Batman (who lived on "Earth-One") begin later in time and with certain elements of his origin retold. Each were depicted as separate, though parallel, individuals living in their respective universes, with the "older" Earth-Two character eventually reaching his retirement and death.

A parallel to this character is introduced in Justice Society of America Annual #1 (2008) entitled "Earth-2" where the Post Crisis Earth-2 is fully introduced. The most notable difference between Pre-Crisis Earth-Two Wayne and his newer Post-Crisis Earth-2 incarnation is that the Post-Crisis Earth-2 Joker is suggested to have killed Wayne which led the Joker to learn the real identities of Robin and the Huntress.

A new parallel to this character was introduced in the 2012 Earth-2 series who remains alive and is out "to protect his only surviving family" at any cost.

Batman's origin and history is essentially similar to the Earth-One version of the character, but events unfold in more of a real-time fashion. For example, the Batman makes his debut in 1939, meets Robin, the Joker, Catwoman and Clayface at various points in 1940, the Penguin in 1941, Two-Face in 1942, etc. These dates reflect the publishing dates of the original stories, rather than taking the Earth-One and Modern Age approach of keeping the characters eternally youthful.
