Brie Larson played Natalie V. "Envy" Adams, who dated Scott before she broke up with him in college. She also went on to date her band's bassist, Todd Ingram (Routh), who was one of Ramona Flowers' aforementioned seven evil exes. During the film, she returns to menace Scott during his battle with Todd. Afterward, she appears to make her peace with him after he calls her by her real name. Before departing, he tells her more people should call her Natalie. 

As the singer of the fictional band The Clash at Demonhead, Envy sings a song called "Black Sheep." The song is about shape-shifting and outer space, which is quite ironic given that in "Captain Marvel," Larson's Carol Danvers battles the shapeshifting Skrulls in space. This film, along with a stage production of "Our Town" in that same year, helped increase Larson's profile as an up-and-coming actress. In an interview with The Guardian, Larson stated that the movie was "a big life-changer."

Without "Scott Pilgrim vs. the World," Larson may not have followed the same career trajectory, which could have altered her destiny with the MCU.
