Loki (Tom Hiddleston), Thor (2011)

Of course, one of the greatest assets of the MCU makes our list. As the adopted brother of Thor, Loki has always felt out of place and unable to escape the shadow of his more revered sibling in the eyes of Asgardian king Odin. Over the course of his three film appearances in the MCU, Loki — as brilliantly brought to life by Tom Hiddleston "“ has tried time and again to secure a throne of his own, even inadvertently uniting the Avengers in an attempted invasion of Earth. Despite his evil machinations, Loki has always been portrayed as a character plagued by inner turmoil and a desperation to secure a sense of belonging and control over his fate. In lesser hands, the role could have devolved into a one-dimensional caricature, but what Hiddleston has done with it is nothing short of astounding. No wonder the actor has inspired a legion of fans all his own, solely through his work in the MCU.
