Fandom: Iron Man (MCU) and Sherlock Holmes (Guy Ritchie movies)
Rating: Teen, for now (for violence, not sex)
Wordcount: ~4800 (Chapter 1 of ?)
Characters: John Watson, Tony Stark, Yinsen
Spoilers: For the first Iron Man movie
Notes: Um. Yeah. Okay. So awhile back, I was doing some prompt meme or another on Tumblr, and someone asked for Steampunk Iron Man. I wrote a quick Tony/Pepper ficbit (based on IM2 continuity) and joked that, if I were going to really write Steampunk Iron Man, it would have to be a crossover with the Guy Ritchie Sherlock Holmes films. As such ideas tend to do, it hung around in the back of my mind for awhile, nagging at me, but it didn't rise up and demand to be written until I realized it would make an excellent fit for one of my trope_bingo prompts: "doppleganger + fusion". It's really only the first chapter of what is likely to turn into a monster fic, but I think it stands alone well enough to submit for the squares.
