In this newly made universe, costumed crime fighters are a relatively new phenomenon, with Superman being the first super-powered hero to come to public knowledge. Since then, several other heroes have come to the fore, with the formation of the Justice League. The success of the Justice League activities inspired the United Nations to create the government-sponsored team Justice League International.
Of course, there are also the supervillains, individuals that use their powers to commit evil, as well as N.O.W.H.E.R.E., an organization with a nefarious interest in superhumans and their abilities.

- Dick Grayson is said to have been taken in and adopted by Bruce Wayne at age 16.

- Jason Todd was introduced to Batman by the Joker.
- Neither of Oliver's parents died on that fateful safari. Moira Queen became a villain and Robert Queen becomes the first Green Arrow.

With his return, he revealed that Prime Earth had been robbed of an entire decade of experiences and memories by some unknown force, and this was the reason the universe did not revert to the way it was before Flashpoint, and why everyone was ten years younger.
According to Mister Mxyzptlk Superman had been split into two beings (New Earth and Prime Earth Superman) by a power beyond even his own. At the end of the battle with Mxyzptlk, his son Jonathan remerges his father and mother with their Prime Earth counterparts. Mister Oz reveals that this action caused the New Earth and Prime Earth realities to merge into a new reality both familiar and new.
In the aftermath of his battle with Mxyzptlk Superman reviews the records of his life at the Fortress of Solitude, but can't shake the feeling that something is wrong. Superman later confides to Batman and Wonder that he believes that his history was being twisted, shaped and reshaped. He also expresses concern that this has happened not just to him but to everyone.
