Yes, that is a misconception of Disney and Marvel… Hades and Loki were a bit jealous of their brothers Zeus (for being king of Olympus) and Thor (for handling the Mnojir), that’s why they make them look like “Disney” villains…
If we go by the Tale of the Dragon campaign it would have to be Shennong (since they appear as enemies in almost every scenario), although in the underworld, the enemies workshipping for Fu Xi, so we would be between those two…
Don’t use MCU movies or Marvel comics to teach you norse mythology. Loki was never the son of Odin. They are brothers by blood pact. Not father and son.
Yes, you’re right… I looked it up on Wikipedia and because of the Mandela effect and general knowledge, I always considered Loki to be the son of Odin and brother of Thor, but Thor’s brothers were Baldr and Vidar, not Loki… damn it Marvel, now I’m going to have to get that fact into my head…
Heimdall is Odins son too. Many Marvel watchers forget that, because of Idris Elbas stellar performence of the MCU character of the same name and job description.
