Movie Battle: Pepper Potts vs Pepper Potts

Pepper Potts when she is wearing the Iron Man suit vs Pepper Potts when she is injected with the Extremis virus.

She actually had feats from when she had Extermis. Extermis Pepper wins.

Extremis Pepper shredded an Iron Man suit that was attacking her already, and it can be inferred that said suit had greater durability than the Mk. 42s truck feat.
