(It's a secret but lets just say it has to do with a modification by H.Y.D.R.A. oh and just imagine her with a black mask like the incredibles have)
Rad Girl punched through the metal door and ripped a small piece of it with quite some effort and strain but she then used it and spun throwing it at Tristan before climbing through the small hole and running up to the main area. She got on the computer and sent all files quickly to H.Y.D.R.A. luckily the computer had no security measures so it made it easier. Then she deleted all of it and stole some small bits of gamma radiation samples and put it in a pocket on her thigh she soon rushed back out of the hole. Luckily she knew he couldn't follow because it was a really small hole and she knew he'd just wait because it was the only exit for her but that didn't make her any less prepared because she summoned past anger to fuel her powers.
