2. Hulkbuster!
The Hulkbuster armour is another suit that went through several versions, eventually resulting in something resembling a tank on legs, but the original version- depicted above- is the most iconic. Quite simply put, the Hulkbuster suit makes Iron Man look like the Juggernaut.
The purpose of the Hulkbuster suit is self-explanatory; it is designed to go toe-to-toe with the Avenger’s most powerful (but least emotionally stable) member. The necessity for this should be clear after The Avengers, which saw Loki succeed in goading Mark Gruffalo‘s Hulk into a destructive rampage aboard the S.H.I.E.L.D. helicarrier, damn near taking down the entire team in the process. If the Hulkbuster suit were to make an appearance on the big screen, it would undoubtedly be in a film focusing on the entire team.
In truth, Stark seems to operate a policy similar to Batman’s in the Tower of Babel storyline, keeping methods of taking down his fellow heroes at the ready, should the need arise. He developed not only a Hulkbuster suit, but a Phoenixbuster and even a Godbuster model, should the need arise to deal with fellow Avenger Thor. The Civil War storyline also saw him bring out tech specifically designed to neutralise Captain America. Its a wonder the other Avengers haven’t taken offence.
