We've seen the primary armor. We've seen the Hulkbuster armor. Now, it's time for more of Tony Stark's Iron Legion to make their way into GTA V, thanks to the power of modding.

Over the years there has been countless variations of the iconic Iron Man armor which appeared in various comics, films, series and games created by Marvel. Some are upgrades of the jack-of-all-trades primary armor, some are specialized. Some adhere to the classic red and gold color scheme, some do not. Most are worn by Tony Stark, their creator, while others aren't. Either way, there are at least as many armor variations as there are alternate universes in the Marvel continuity, and more.
One modder, JulioNIB, decided some time ago to bring Iron Man to GTA V and created his mod. The files, once added to GTA V, allow players to don the powered exo-skeleton in Los Santos, and make use of its various abilities, such as super-strength, flights and the unibeam. He later also created a Hulkbuster mod, which allowed players to call on the gargantuan armor and its enhanced abilities.
