After watching the series of mini movies that are apart of Superman/Shazam!: The Return of Black Adam it is clear that DC could do a Jonah Hex Animated Series.
We have seen from Batman the Animated Series that Jonah Hex has already tangled with Ra’s Al Ghoul and his son. Vandal Savage could also be a villain in his quest to conquer the world. I like the idea of a western theme world where Hex deals out western justice. Two major villians who we all know will outlast him can help influence and shape the overall story arch. Create new villians for Hex to fight. You can do Jonah and Django 3 part episode.
