Hey! Mary here with Cassie Lang, the sweet daughter of Ant-Man. I honestly wished she looked like Emma Fuhrmann but ther are no icons of her and well, she was recasted with Kathryn so... Anyway, onto the important stuff!
Cassie is a mix of MCU Cassie and Comic Cassie. Why? Because I wanted her to have superpowers and I doubt Scott would have left an Ant-Man suit laying around she could play with, AND since we're not getting Quuantumania till 2023... I have to improvise lol I left it a little vague, just saying that she somehow can shrink or grow depending on her emotions, which she's working on controlling. But hey, she's 16 so maybe she ends up growing twice or triple her size if you piss her off, who knows?
She's rooming with Carol Danvers, which she thinks it's super cool. All her info is here.
