A suit stops a short way away from Iron Man. It's not Sentinel colors. Some sentinals fly near her and she immediately raises her hand and fires missiles at the closest one, exploding it on impact, she levels her other arm at the one who Stark would recognize as out of range. She fires anyway, and gets a bullseye, blowing it up in a spectacular explosion.

It turns to Iron Man, and Heidi's voice speaks out. "Hey, Tony. I'm the backup."

She turns off the mic. "Jarvis, increase cushioning and buffers around my stomach and chest." The suit whirrs into action at her command.
