 Thor 's adoptive brother and nemesis , based on the Norse mythological deity of the same name . About his character 's evolution from the film Thor , Hiddleston said , " I think the Loki we see in The Avengers is further advanced . You have to ask yourself the question : How pleasant an experience is it disappearing into a wormhole that has been created by some kind of super nuclear explosion of his own making ? So I think by the time Loki shows up in The Avengers , he 's seen a few things . " About Loki 's motivations , Hiddleston said , " At the beginning of The Avengers , he comes to Earth to subjugate it and his idea is to rule the human race as their king . And like all the delusional <unk> of human history , he thinks this is a great idea because if everyone is busy worshipping him , there will be no wars so he will create some kind of world peace by ruling them as a tyrant . But he is also kind of deluded in the fact that he thinks unlimited power will give him self @-@ respect , so I haven 't let go of the fact that he is still motivated by this terrible jealousy and kind of spiritual desolation .
