The Marvel Cinematic Universe has covered many realms of the universe, from the cosmic to the magical. However, the supernatural side of the MCU has many sects that have only just begun to be uncovered in Phase Four. Initially, sorcery was the farthest the universe went as that alone featured many dimensions like the Dark Dimension and Mirror Dimension. As a result, it took some time before other forms of magic, like witchcraft, took center stage in shows like WandaVision. However, the most surprising addition to the MCU so far has been the world of monsters, which was kickstarted officially with the introduction of Blade in Eternals.
