Indeed look, at how the story of Kringle has evolved, Odin was part of it in mythology with Christianity absorbing the ‘pagan’ Norse religion, but I bet Vadderung has in recent decades started to get a wicked thirst for Coca Cola, neat.
Harry has never done a summoning for Kringle it would be very interesting to see him do one, and what he would use given the evolution of his personal mythos.
The same should apply with the Odin aspect, the MCU will have been pulling that in a radically different direction in the last decade and a bit in particular, but sounding like Sir Anthony is better than an unquenchable thirst for the real thing.
I do wonder if the creation of the Vadderung persona was to counteract these different pulls? No real public aspect unlike Kringle or Odin to be manipulated. As Vadderung Odin/Kringle can be more himself. We know how Mab feels about Disney, how much of a pull is that on her? Does the freedom Molly has in the Good People reflect the effect of Frozen, allowing her to stay attached to her family? To do ‘good’?
The MCU/Marvel Comics doesn’t really include the Einenjhar (unless those were Hel’s Soldiers) but does include Valkyries. Is this reshaping Valhalla?
