The Marvel Cinematic Universe has endured some massive shifts since the conclusion of Phase 3 and the defeat of Thanos. While Phase 4 served as a reconstruction period, introducing new names like She-Hulk and Moon Knight, Phase 5 picked up hot off the heels of the debut of Kang the Conqueror, or rather one of his variants in the Season 1 finale of Loki. With the death of a final variant known as He Who Remains, he promised that his death would unleash the Multiverse and a dynasty of Kangs that would wreak havoc on all realities. Now, with Loki Season 2, audiences are finally seeing the urgency of this situation in full force and the idea of trying to stop an enemy that's otherwise a mystery to everyone involved.
