Fan Fic: Agent Loki International Man Of Mayhem

Agent Loki: International Man of Mayhem by Dee is an exceptional 13-part series of The Avengers / Thor fanfics exploring the idea of What if SHIELD kept Loki instead of sending him back to Asgard and rather than keeping him in a cell forever decided to make use of him? Notable, among other things, for mostly being written as a Second-Person Narration from Loki's point of view.

Also has a number of outakes and deleted scenes.

Additionally, this Alternate Universe fic also has its own AU in the form of Dee's other massive story, Small Things.

It is with great regret that we inform you that Dee has recently taken down the story, and indeed, all her work from aO3. While links to alternate sites where the story may be found would be appreciated, it is important to note that the author herself does not wish it to be circulated any more than it already has been.
