Cassie Lang

The daughter of Scott Lang, whose congenital heart condition originally motivated Scott to steal the Ant-Man suit to save her life. In the comics, Cassie is the emotional anchor of the narrative; a resilient girl who faces the trauma of her father's death and fights desperately to honor his legacy. As the hero "Stature" (and later "Stinger"), she earns her place in the Young Avengers not just through Pym Particles, but through grit, heart, and a complex journey from a sick child to a giant warrior.
