You might have not remembered her. She’s more a plot device than a character. She shows up as a world renowned genius we’ve never met but can build... life. Then she goes to a party where intron breaks out and most people just remember the avengers trying to lift mjolnir, she is brainwashed and helps Ultraman build his body, and then helps bipod vision. She’s never really a pivotal character nor is she ever really the focus of any scene. She shows up to solve a problem that was created just to make the plot work, then she pushes some of the more tedious scenes forward, and finally they check up on her a little so the audience doesn’t go: “wait... they don’t even care about the lady they were friends with earlier this week...?” I didn’t remember she was in the movie until I saw this meme.
The chick on the right is Helen Cho.
