This is super exciting: Two Iron Man 3 TV spots released today show Pepper Potts saving Tony Stark while wearing the iconic Iron Man armor. Looks like Tony's second-in-command Potts will be holding her own in battle.
She's been a capable businesswoman in the Iron Man movies and The Avengers, and has sometimes but not always escaped the damsel-in-distress role. She was part of the final battle in Iron Man 2, but only phoned in her contribution to the ending of The Avengers.
In the Iron Man comics, Potts had the superheroine name Rescue and began to use the armor only after undergoing a severe injury that left her heart damaged.
Iron Man 3 premiers May 3, 2013 and features Tony and Pepper facing off against The Mandarin.
