Cassie Lang is from the Yost Universe series The Avengers: Earth's Mightiest Heroes.

Cassandra Lang is the daughter of superhero Scott Lang, also known as Ant-Man.


Cassie developed a condition that required many expensive hospital bills. Her father paid for them and she got better, but he was arrested because he committed robberies to do so.

He got out of jail and began work as a janitor at Grayburn College. Soon she was kidnapped by her father's former criminal boss Crossfire.

She was being held and threatened when her father came in dressed as Ant-Man. He gave Crossfire the money, but the boss wanted to use the Ant-Man powers to commit more crimes. Hank Pym, Luke Cage, and Iron Fist arrived to help Scott. Pym shot a Pym Disc at her shrinking her. Scott found his daughter and returned her to normal size, and she wanted to do that again. Her father then defeated Crossfire. Pym allowed Scott to keep being Ant-Man and her father was offered a job on the Heroes for Hire.


Cassie was voiced by Colleen O'Shaughnessey, who was uncredited.
