The Mark XV Armor (codenamed Sneaky) was Tony Stark’s fifteenth Iron Man suit and was the first suit designed to specialize in stealth capabilities. It was a part of the Iron Legion. Notably, it was the first armor to receive a nickname that Stark would commonly use to refer to it. It was destroyed when Tony Stark fell from the explosion of the Mark XLII on the Battle on the Norco.
The Sneaky Armor was made by Tony Stark after the Battle of New York. As part of the Iron Legion, the Sneaky Armor was used by Iron Man and Iron Patriot during their battle against Aldrich Killian and hisExtremis-enhanced soldiers. It was destroyed when Tony Stark fell from the explosion of Mark XLII.
Designed to be the first Iron Man suit to specialize in stealth capabilities, the Mark XV integrates principles commonly used in stealth aircraft and other anti-radar-detection systems, as well as color camouflaging technology, and is primarily used for sensor invisibility. The armor features several angled surfaces, as well as radar absorbent materials, that make it virtually invisible to enemy early-warning systems. A chrome colored coating on the armor can darken or lighten to match the environment, and make the armor harder to see from a distance.
