I'm currently developing a sort of sequel to Supernatural that incorporates all these elements. In this story, the Antichrist becomes one of the main villains. The setting is in a different universe where Dean has twins—legendary as The Twins of Darkness—who are Amara's children but were raised by Dean himself. Alongside Sam's son, these twins embark on a journey to uncover and confront the legacy left by their fathers, all while forging their own paths. They grapple with their own inner demons and the sins of their fathers.

In this universe, Rogue Angels prefer Chuck to be in charge, so they plan to resurrect him. Jack is cast out of Heaven and unable to reach Sam and Dean for help, so he teams up with the twins, their cousin, a group of hunters, a vampire hybrid, and Crowley's daughter to prevent a new apocalypse. The Antichrist and the Twins of Darkness are key to bringing Chuck back, but Chuck's return is the least of their worries when they face Lazarus.
