ALL RIGHT, HERE WE GO:
(My first forays into the Avengers fandom was through Frosthawk, so I have a few fics from that. Haven't read any of them recently so idk if I still like them even, but I have them saved, so here are the links:)

http://archiveofourown.org/works/1268161/chapters/2618806 (can you tell? I like de-aged Tony. he's adorable, okay?)
http://archiveofourown.org/works/903686/chapters/1747844 (kitty tony is also great)
http://archiveofourown.org/works/1617179
http://archiveofourown.org/series/105272 (First one was D: so many feels. Second one didn't quite have the same impact for me)

My own Superfamily ficet I will shamelessly (okay, fine, actually really self-consciously) promote:
http://archiveofourown.org/works/1850632
Not a fic, but...
http://ship-manifesto.livejournal.com/204146.html
Great run-down of the ship, leading us through years of backstory and history. But remember this is a few years out of date. Steve's alive, so yes, temporarily dead. (I mean come on. He's a comic book character. No one stays dead in comic books)
ALSO IS GREAT CHARACTER ANALYSIS AND THIS IS WHY "SUPERIOR" IRON MAN SHOULD PISS YOU OFF SO MUCH; BECAUSE GODDAMN TAYLOR IS A FUCKING IDIOT. And dear god, he's a Remender fan. That explains some of it. But fucking fuck, this is how Taylor thinks: "...the old Tony is back. Arrogant. Cunning. Witty. Superficial. Completely self-obsessed. Superior."

I can't wait until this is over and someone ret-cons it. Or it's along the lines of Jenngeek's theory (but this gets into the realm of "you won't get it until you get more into the Marvel-verse)
