That version of Loki will lead his own Disney+ series, using the Tesseract (the Space Stone) to meddle with history. After fans were given their first tease of Loki via an image of the character in the 1970s, an MCU Disney+ Super Bowl commercial briefly showed Loki sporting a Time Variance Authority jumpsuit. In the comics, the TVA is an organization that monitors the multiverse and subsequent timelines, eliminating those deemed too dangerous.
Loki will reportedly introduce Kang the Conqueror, a time traveler who comes into contact with the TVA on more than one occasion. In the comics, Kang has close ties to both the Avengers and Fantastic Four.
Loki is slated to begin airing on Disney+ sometime in 2021.
