  • Reasonable Authority Figure: He's indicated to have put up with a lot from Loki before exiling him to the Isle of Silence, and while he ultimately resorts to extreme measures (trapping him at the bottom of the World Tree with Jormungand dripping poison into his eyes), he only does so after Loki nearly destroys all Nine Realms. Moreover, while he initially credits Thor with saving Asgard and the Nine Realms, when Thor demurs and reveals that the Avengers saved him, and Asgard and the Nine Realms, he directs his congratulations to them, referring to them as, "the mightiest heroes in the Nine Realms."
