Infinite New Possibilities, Star Wars: The Force Awakens, with about a billion spoilers for the entire movie, rated General but with warnings for mentions of past torture. This work is what I go to fanfic for: it's filling in the blanks of what was missing during the movie; it gives us more character development for almost everyone who I care about, and the first chapter contains a lovely, touching scene where Poe gives Rey a tour of the Resistance base, and the two of them talk about what's to come. I haven't read the second two chapters yet, but I'm really impressed with the way the first part went, and I'm glad to recommend it.
Edited to add: The Force Awakens as an adorable manga-esque High school AU. This may just be the most adorable thing I've ever seen. It fits in with emo!Kylo Ren's twitter account nicely, too.
The Please Help Me Cosplay! tumblr is still chugging along, and there's a comprehensive list in the top entry right now that gives a ton of book and website references for everything from homemade foam armor to costume patterns.
American Captain is a diary comic about Steve Rogers' experiences in The Avengers and beyond. It's a rocky story: Steve struggles with PTSD and survivor's guilt; 2010 is alternately amazing and terrifying; and his new teammates are supportive but often confusing. I like how small it feels, and I don't mean small as in insignificant or stupid, but it feels small and right, the way things would if your universe suddenly exploded and reformed itself into something sort of familiar but not really. Such a great fan comic.
