Loki is a fictional character played by Tom Hiddleston, known mainly for being the antagonist in the 2011 film Thor and the 2012 film The Avengers. The Loki from the comics got absolutely no attention until the movie Thor was released, a fandom growing overnight originating from Tumblr. Since then, he has taken over the website with fan fiction, blogs, cosplays, gifs, and much more that I cannot fit on listing in this little definition of Loki. He has also spread along Deviantart, approximately 196,823 results coming up when searching Loki on Deviantart and about 32,800,000 results when searched on Google.
Many memes have been created based off of this character, a well known one being ’Loki’d.’
