Loki, the god of mischief is the misguided brother of Thor, the god of thunder. Considering how much cooler thunder is than mischief, I can see where Loki believes he got the short end of the stick. But what if there was an alternate universe where Loki was the god of thunder instead of Thor? While not the exact plot, that is kind of the idea behind the new Loki series. We see an alternate Loki get recruited by The Time Variance Authority, tasked with keeping reality in order! That requires messing with time, and we are here to explain all the crazy stuff going on. We talk about mobius strips, pocket dimensions, tiny wormholes, and a quantum world where Ben only ties his left shoe.
