6. The Superior Armor
After his personal moral polarity was inverted, Tony Stark became a right evil jerkwad. Like, suuuuuuper evil. And, of course, evil means a new armor and a new comic book.
During the run of Superior Iron Man, Tony created the Model 50, or the Endo-Sym Armor. This armor wasn’t based on nanotech, but on alien symbiotes, like the kind that just loved trying to kill Spider-Man. If this sounds like a terrifyingly evil idea, that’s only because it was. The suit didn’t last super long, but neither did evil Tony, which I feel was a mistake.
Tom Taylor really had something fun going with that one. The suit was created during the Avengers and X-Men: Axis event, and it lasted for about a year, until Secret Wars did away with it in a hand wave.
It was best used in Unbeatable Squirrel Girl (Vol. 1) #2, which is hilarious, and in Nick Spencer’s Ant-Man run, which still makes me laugh every single time I read it.
