Thor Places Mjolnir On Loki (Thor)

Loki’s first appearance in the Marvel Cinematic Universe was in 2011’s Thor, in which he was the main villain – but he did have some weirdly warped good intentions.

He wanted to entice his biological father Laufey to attack Odin, and then use the attempt on the Allfather’s life as an excuse to destroy Jotunheim with the Bifröst Bridge, thus proving himself worthy to his adoptive father.

Thor stepped in, destroying the Bifröst to prevent Loki’s plan from coming to fruition – and trapping himself in Asgard, away from his new love Jane Foster – in the process. In the final battle between the adoptive siblings, Thor subdued Loki by knocking him to the ground and placing Mjolnir on his chest. Given that nobody other than Thor could budge the war-hammer, Loki was trapped there.
