Thor in the Marvel Cinematic Universe is one of the most storied and tragic characters in the franchise. When he first appeared, his hubris taught him a lesson in humility and protecting others, not for himself but because it was right. From there, he learned that he wasn't ready to rule and instead chose to be more traveled, protecting Earth with The Avengers. But when Ragnarok arrived, he had lost almost everything he held dear, from his home to his family. This was compounded in Thor: Love and Thunder when he even lost the love of his life, Jane Foster.
