Marvel's "Ant-Man and the Wasp: Quantumania," which arrives in theater Feb. 17, will introduce viewers to lots of characters for the first time, including Kang the Conqueror (Jonathan Majors) and M.O.D.O.K. (Corey Stoll). But the movie is also set to reintroduce a new character from the Ant-Man series, Cassie Lang, played by Kathryn Newton. In this exclusive featurette about the new film, Newton and the rest of the cast lay out Cassie's journey and how she ended up at the center of the new film. Watch the clip above!

"Cassie Lang wants to change the world," Newton says in the featurette. "She likes the chaos, she wants to be fighting, and she wants to be in the middle of it. She's being influenced by these superheroes around her." The two biggest influences on the teen? Her dad Scott Lang (Paul Rudd), aka Ant-Man, and his girlfriend Hope van Dyne (Evangeline Lilly), aka Wasp.

In the new movie, Cassie has her own shrinking suit just like they do, and she's led creation of technology that contacts the Quantum Realm. When she, her dad, Hope, Janet van Dyne (Michelle Pfeiffer), and Hank Pym (Michael Douglas) get sucked inside the realm, things quickly get out of control.

"She just wants to be a superhero like her dad," Newton reflects in the clip. "She just wants to impress him." And Scott wants to impress his daughter, too. In 2015's "Ant-Man," which introduced the characters, Cassie (played then by Abby Ryder Fortson), is just a little girl. Her mom Maggie (Judy Greer) wants to protect her from Scott, who's a petty thief newly out of jail. Cassie also appears in 2018's "Ant-Man and the Wasp" as a little girl and tells her dad that she wants to be a superhero with him. But at the end of the movie, Scott is stuck in the Quantum Realm, and he doesn't get out until five years later, as shown in "Avengers: Endgame" (2019). By then, it's 2023, and Scott has missed so much time with his daughter.

In the new film, their relationship takes center stage, and where that will lead is anyone's guess. In the comics, Cassie does become a hero, and she's used two different names: Stature and Stinger. As Stature, she's a member of the Young Avengers, while as Stinger she's a hero duo with her dad. We'll have to wait to see which path she'll take in "Ant-Man and the Wasp: Quantumania."

"Ant-Man and the Wasp: Quantumania" hits theaters on Feb. 17.
