Super-Sons

Although the very first Super-Sons appearance stated that these were actual stories in the lives of Superman and Batman, the final story in World's Finest #263, "Final Secret of the Super-Sons", written by Dennis O'Neil, revealed that the Sons had never really existed — they were merely computer simulations of what might have been, created by Superman and Batman on the Man of Steel's computer in his Fortress of Solitude.

They later inspired the characters Joel Kent and Bruce Wayne Jr. in the three Superman & Batman: Generations comic book series.

It was thought that the events of the Crisis on Infinite Earths limited series had erased Superman Jr. and Batman Jr. from DC continuity, but this assumption was later shown to be incorrect.

[4] The Earth-154 variant of the Super-Sons (and their fathers) appear briefly during the Infinite Crisis limited series, during which time Alexander Luthor, Jr. of Earth-Three warps reality in an attempt to restore the DC Multiverse.

During his subsequent attempt to consume the multiverse, the evil Venusian worm Mister Mind altered each of the parallel worlds, creating distinct histories for each.

In this new timeline, the Super-Sons (Chris Kent as Superman and Damian Wayne as Batman) reside on Earth-16 as members of the Just—the sons and daughters of the classic JLA who have inherited a crimeless, utopian universe and so live as idle celebrities.

In December 2007, DC Comics published a trade paperback collection of the series entitled Superman/Batman: Saga of the Super Sons.

[11] In the Superman (2016) series, issues 20 to 25, a storyline known as “Black Dawn” features Damian Wayne (Robin) and Jon Kent (Superboy).

While their roles are not central to the overall storyline, it does effectively highlight their individual strengths and weaknesses, and sets the stage for their future team-up in the Super Sons comic book series.

This issue marks their first meeting since Jon aged five years ahead of Damian due to time travel, significantly altering their dynamic.

[12] An alternate version of the Super Sons named the Bizarro Boyz appeared in the four-part story "Boyzarro Re-Death".

[16] The Super Sons, Jon Kent and Damian "Ian" Wayne, are featured in a three-part graphic novel series by author Ridley Pearson and artist Ile Gonzalez.
