Hannah John-Kamen last played Ava Starr, AKA Ghost, seven years ago. The character was introduced in 2018's Ant-Man and the Wasp as a woman who has an unstable molecular condition as a result of an experiment gone wrong. Although her condition allows her to phase through solid objects, it's also fatal, and she clashes with the movie's heroes in her attempts to stay alive.
Now, though, Ghost returns in Thunderbolts* – albeit in a much more stable, controlled state – reluctantly teaming up with some other familiar faces, including Yelena Belova (Florence Pugh), Bucky Barnes (Sebastian Stan), and John Walker (Wyatt Russell), to get themselves out of danger. But did John-Kamen expect Ava to have this sort of longevity in the MCU?
