4. The Model-Prime
Using what he learned from his evil time with the Endo Sym Armor (Model 50), Tony decided to apply that knowledge to a heroic armor. Here’s what he came up with.
Also known as Model 51, the Model Prime armor was able to shape itself into any needed suit, allowing it to be a sort of all-in-one suit. The result was sleek and elegant in its design. After the super-complex Bleeding Edge and Extremis armors, this took it back to basics in a really great way. I love this design. The suit came about after the most recent Secret Wars, and lasted Tony through the second Civil War.
During its run, Tony helped found the All-New All-Different Avengers, fought back the jailbreak of Pleasant Hill during Avengers: Standoff, and dealt with the Vision’s declining mental health in his own series.
The armor didn’t last crazy long, but it had some really fun stories in its time. It also inspired the Riri Williams armor, which I also think was pretty great-looking.
