Tom Hiddleston has become a staple for Marvel with his portrayal of Loki that has made every other villain after him look so boring and mundane. The actor brings an intensity that is unmatched to the role and was feared in three movies within the universe, but could he be heading to his time as the God of Mischief?
Hiddleston recently nabbed the lead in the King Kong prequel Skull Island, which could turn into a universe of its own with Godzilla also doing well and the two movies possibly leading to a merger. With Hiddleston now leading his own franchise, it may mean the end for him as Loki for Marvel.
The rumored plot for Thor 3 is to follow the Ragnarok storyline, which includes the destruction of Asgard. As of now, Loki is posing as Odin on the throne in Asgard but that could change when Thor returns home after the events of Avengers 2.
In the comics, Loki falls during Ragnarok, an event he helped begin, and this could be the exit Hiddleston gets to putting the character to rest for awhile. While he "died," during Thor 2, this could be the first major permanent death that Marvel does and would allow the villain to rest while its actor goes to do his own show.
If he doesn't want to completely give up the role though, the death would allow for another fake-out that Marvel has done multiple times by now and maybe he could return in a shorter role in either another Thor movie or a cameo in a Guardians of the Galaxy sequel.
Thor 3 is rumored for a 2017 release date.
