When Dr. Olga Pacherov succumbs to her new savage, animalistic side, and transforms into her powerful, slimy alter-ego, she's known as 'The Flow', after the codename given to the Parasitic Gene that inhabited her body and forcibly reassembled her genetic makeup. It cured her foot, but also 'cured' all other 'weaknesses' in her humanity. She's faster, stronger, smarter, and extremely dangerous. Approach with caution.
I wonder if there's a significance to the number of fingers she's holding up.
