Last week, it was announced that J.J. Abrams is producing a new Superman film for Warner Brothers which will be written by Ta-Nehisi Coates. Not long after that announcement, additional reports suggested that the film would be built around a Black Superman rather than having Man of Steel and Justice League star Henry Cavill reprise the role, although there has been no official indication whether or not this is true.
If the film does in fact introduce a black Superman, there are a couple of different ways it could do so. While it could be as simple as casting a black actor as Clark Kent there are also separate characters in the comics who are black and use the Superman identity. One such character is Val-Zod, who served as DC's second Superman of Earth-2 during the New 52 era.
Val-Zod was created by Tom Taylor, Nicola Scott, and Robson Rocha, Val-Zod first appeared in 2014's Earth 2 #19. As the title implies, Earth 2 was set in an alternate universe separate from the New 52's Prime-Earth. Earth-2 had its own version of Kal-El/Clark Kent who served as Superman, but he was believed to have died in the planet's first war with Apokolips. When Steppenwolf launched a second Apokoliptan invasion years later, one of his allies, called Brutaal, revealed himself as Kal-El, who had been brainwashed to serve Darkseid (it was later revealed that this was actually a clone of the real Kal-El). The clone killed Steppenwolf and decimated Earth 2's heroes before moving to conquer the planet himself. Aware that Terry Sloan was keeping an alien prisoner in the World Army's Arkham facility, Lois Lane, Thomas Wayne, Jimmy Olsen, Major Sonia Sato, and Aquawoman discover Val-Zod living in a regular apartment.
Val is staying in the apartment/cell voluntarily and is frightened to go outside. When the heroes enter the cell he has a reaction to a shard of Kryptonite Thomas (who succeeded his son as Batman after Bruce died) has with him, leading the others to realize he is Kryptonian. Val's parents had been executed by the Kryptonian court, after which he made friends with Kara Zor-El and was taken care of by Jor and Lara-El, Kal-El's parents.
When Krypton was near destruction Jor and Lara sent Val to Earth as they did with Kal and Kara. But Val wound up stuck traveling in his pod for a very long time, resulting in him being agoraphobic when he arrived on Earth, where he was taken in by Sloan. Lois managed to inspire him to face his fears and go outside so he could discover the power Earth's yellow sun could give him.
Because of his parents' teachings, Val was a pacifist, but he eventually took on the mantle of Superman and defeated the Kal-El clone in a final battle. After this, he continued to serve as the new Superman in both the Earth 2: World's End series and the subsequent Earth 2: Society in which he and the other Wonders (Earth-2's heroes) protected the survivors of their world, who had colonized a new planet after Earth-2 was destroyed.
Considering the much-hyped importance of the DC Multiverse and the Justice Society -- the team that inspired the Wonders -- to DC's cinematic future, Val would make sense on the big screen, given the mythology he is associated with that's already heading to the DCEU.
