There have been numerous rumors that Pepper Potts might wear her Rescue armor in Iron Man 3. However, what we’ve heard is that Pepper Potts does put on armor in Iron Man 3, but it is not necessarily called or identified as Rescue armor.
The new costumes from Disguise would seem to support that Pepper Potts wears armor in Iron Man 3, but it’s not called Rescue armor. One of the Iron Man 3 costumes is labeled as Pepper Potts in Mark 42 armor. One theory could be that the costume company just wanted to produce a woman in armor costume so they picked Pepper Potts.
However, there are two other Mark 42 armor costumes for women that aren’t labeled as Pepper Potts, so that would seem to eliminate the possibility that they felt they had to use a character from the film to create a female Iron Man costume.
Iron Man 3 is scheduled to be released in movie theaters in the United States on May 3, 2013.
