Tony as Villain
Hello all! I'm looking for recs of fics where tony either gets brainwashed, or does a SHIELD exercise to act as a villain. Cue everyone underestimating him, and then Tony subsequently kicking all of the Avengers' butts.
Prefer no AU where Tony is the villain for real from the beginning, but will accept villain!Tony fics where he goes to the 'dark side' after Afghanistan or CAWS or civil war, etc. What I really want is that underestimation and ultimate vindication that Tony is a surprising BAMF.
Any ships welcome. Thanks for your help!
