Phase 4 of the Marvel Cinematic Universe could potentially confuse a lot of people. There have been hints about the multiverse throughout Marvel movies such as Doctor Strange, The Avengers and many others. The multiverse is a concept that suggests there are an infinite number of timelines that run parallel to the one we are following. That means that there an infinite number of each character known as variants.
The Loki series has opened this concept wide open. We were first introduced to Kang The Conquerer in the Loki series. Kang was responsible for looking after the timeline that we follow in the MCU. He created the TVA, (The Time Variance Authority) in order to keep the timeline from branching out which might allow all timelines to clash. Kang is now dead and the TVA no longer exists as it once did. Now variants of all characters from several different timelines will for sure appear in future projects. Is it about to be very confusing? Yes. Very. I don't know if I fully love the concept because it provides a lot of plot armor for the heroes and raises many more questions than answers in my opinion.
