History
Bruce Banner was taking refuge in Kolkata, India, trying to hide his powers and became a doctor to help the nearby villagers. One day, a little girl pleaded for him to go help her sick father. The girl led Banner to an empty cottage and disappeared without a trace. Inside, Natasha Romanoff was waiting for him, as S.H.I.E.L.D. had set up the whole thing in order to recruit him to join the search for the stolen Tesseract after it was stolen by Loki, as Banner was the world's foremost authority on Gamma Radiation.
