Character Background and MCU Timeline
Cassie Lang is the daughter of Scott Lang (Ant‑Man) and his ex‑wife Maggie Lang. In the comics, Cassie becomes the superhero Stature, but the MCU has thus far focused on her role as Scott’s daughter. Because the Ant‑Man films incorporate time‑travel and quantum realm elements, multiple versions of Cassie appear at different ages, sometimes overlapping in the same narrative space. This allows the films to explore Scott’s relationships and responsibilities across timelines while keeping Cassie an important emotional anchor in his journey.
