Helen Cho (Earth-1352)

"What you are asking of me is impossible. The regeneration Cradle prints tissue; it can’t build a living body."

- - Doctor Helen Cho

Doctor Helen Cho (Hangul 초헬렌) was a South Korean geneticist and physicist and a long time friend of Tony Stark responsible for creating the Cradle, a device that could print living tissue. She was used by Ultron to create Vision with the help of the Mind Stone and killed afterwards.

Early Life
Helen Cho was born in Seoul, South Korea who became worldwide famous duo to her studies on the printing of living tissue. She eventually built the Cradle, a mechanical equipment which would allow Helen to continue her work. During her years of work, she became a friend of Tony Stark.

Return of Brainiac
Doctor Cho was called upon the Hall of Justice by Stark after his teammate Flash was injured during the final battle against HYDRA at Sokovia. She helped heal him with the help of the Cradle, and was then invited to celebrate a party at the Justice Tower.

Helen went to the party and even remained after it was over with the members of the Justice League, Colonel James Rhodes, and Maria Hill, where all of them attempted to lift Thor's hammer Mjølnir. However, they were soon interrupted by a returning Ultron, who infiltrated one of Iron Man's armors. She was almost killed by Brainiac, but was saved by Wonder Woman with her bracelets.
