Cassie’s Super Hero Debut
In Young Avengers (2005) #2
Cassie debuted in MARVEL PREMIERE (1972) #47, the same issue her dad was introduced as the new Ant-Man. She realized over time that her dad was Ant-Man, and secretly experimented with Pym Particles on her own. When she tried to join the Young Avengers, the team didn’t accept her at first. As Cassie furiously criticized them, she grew in size, changing the mind of the Young Avengers under the codename Stature.
