In the end of the Injustice comic, there was a resolution that balanced justice and redemption. Different heroes and villains had their own fates, and it left readers with a sense of closure and hope for the future of the DC universe.
The first Shazam comic made its appearance in 1940. Since then, it has gained a considerable fan following and has been an important part of the comic book landscape.
The comic was the original source. The Injustice game was developed later, inspired by the comic's concepts and universe. This allowed the game to build on the existing lore and expand the story in a new medium.
