First: Evil!Tony! Eeeee! *vibrates with happiness*
Second: According to the internetz, this story came out a full year before Civil War. The whole time that everyone was running around going crazy, and Steve was hiding out in SHIELD safe houses, and Tony was doing that stuff, and Maria Hill was doing that other stuff... the whole time, SHIELD has got a second Tony Stark just lying there like a tuna on ice, and they ignore him? Or, if you want to be meta about it: Marvel ignores him? This is not some minor, throwaway character, guys! This is Evil Tony Stark, boy genius!
Third: There are two Tony Starks. Really. Canonically. Where's the slash?
The evil twin who didn't strike back
