One idea that’s been floating around in my head lately is a story about a thief being hired (or deciding on her own accord) to steal a super soldier formula. She infiltrates the complex it’s being kept in stealthily and quietly. Then she finds it and for some reason or another ends up taking it herself. She grows from a thin, petite woman into a gigantic muscle monster, and smashes her way back out.
I find the contrast between her initial approach and her escape interesting.
