Iron Man's White Armor Was Only Briefly Used In The MCU

White Iron Man armor has appeared in various contexts, often symbolizing purity, new beginnings, or specialized functions.

Tony Stark's Mark XXXIX armor, codenamed "Starboost," made a brief but memorable appearance in Iron Man 3. The sleek, white armor was for sub-orbital flight, featuring advanced thrusters and a reinforced design suitable for the extreme conditions of outer space. The Mark XXXIX was unveiled as part of the Iron Legion during the climactic final battle when Stark initiated the "House Party Protocol," summoning all his suits to aid in the fight against Aldrich Killian's forces.

The Mark XXXIX is the third armor from the left in the iconic Iron Legion image from Iron Man 3.

Despite its advanced capabilities, the Starboost armor met an abrupt end. After playing its role in the battle, it was destroyed alongside the rest of the Iron Legion when Stark activated the "Clean Slate Protocol." This dramatic self-destruction of his armor symbolizes Stark's commitment to Pepper Potts, emphasizing that his love for her is greater than his obsession with his suits.

Another white armor (Model 50) was introduced in Superior Iron Man #1 November, which was designed to imitate symbiote biology.
