Just like several iconic movie franchises, such as the MCU and Star Trek, Riverdale has created its own multiverse by including several alternate timelines and universes. Beginning in 2017, Riverdale is a supernatural teen drama that initially followed Archie Andrews and his friends, who all find themselves caught up in a murder investigation after their classmate, Jason Blossom, is found dead in Sweetwater River. While this investigation was at the heart of the series in season 1, the Riverdale writers soon began to explore other genres, such as the supernatural and horror, to keep the viewers engaged as the seasons went on.

While Riverdale is often known for its wild storylines, the writers took a huge risk in seasons 6 and 7 when they began setting up their own multiverse. After Archie survived the bombing in "Chapter One Hundred And One: Unbelievable", he and the rest of the main characters learned they had superhuman abilities.
