Disclaimer: Sadly, they aren't mine, I'm just playing with them for a while.
Notes: Written for the au_bigbang. Art by the lovely and talented inanna_maat. Set from immediately after Dean drives away from Sam at the end of "99 Problems". A fusion of the Supernatural and Legion universes. You don't need to have watched the movie Legion to be able to read the story. Angelic lore and appearance is taken from Legion, so any deviation from SPN canon comes from the movie.

Summary: Unable to see any other way out, Dean says yes to Michael. But the result isn't what he or the archangel expected. When Raphael demands Sam's death, Michael rebels and with Gabriel's help, joins forces with Sam and Castiel. Together, they face not just Lucifer, who's hell bent on forcing his vessel to say yes, but also Raphael and the host of heaven.
