Just a lil PSA: According to Norse mythology, Thor, Odin and Fray die after the events of Ragnarok (doomsday). Also, in marvel comics, Thor dies after fighting a serpent, which is the probably the same one he is destined to in Ragnarok. The serpent is actually Loki's kid, so basically Thor gets killed by his nephew. Anyway, let's hope he doesn't die in the movie I don't need another dead Thor.
