4. Pepper Becomes Rescue
It's been rumoured for a while that Pepper Potts might end up getting her own Iron Man armour and become Rescue as she was known in the comics. Though this doesn't strictly happen, there are plenty of teases throughout the film. For instance, early on during The Mandarin's attack on Tony's home, Tony gets Pepper kitted out in one of his Iron Man suits, and then later on when Pepper is infected with the Extremis virus, we get to see her kick some ass. So no, she doesn't formerly become Rescue, but as for the next Iron Man film (come on, Iron Man 4 is inevitable), all bets are now off.
