Evangeline Lilly has revealed how her character Hope Pym has evolved since the first installment of "Ant-Man."

The actress shared that her character in the upcoming "Ant-Man and the Wasp: Quantumania" is "completely a different person" compared to what the audience saw in the 2015 movie.

"At that time, she was closed, she was cold, she was very isolated; she'd had her heart broken at a very young age, and had just remained a bit of a fortress ever since then," she explained in an interview with Fandango on Tuesday.

The 43-year-old actress went on to explain that in her character's journey throughout the Marvel movies, Hope allowed the ice around her heart to melt, especially after she "repaired her relationship with her father."

Hope has also changed because she has "brought her mother back from the Quantum Realm; as she has fallen in love - and then, also, as she has sort of taken on this mantle of stepmother to Cassie [Cassandra Lang]," Lilly noted.

Kathryn Newton plays Lang's character.

The actress feels Hope's life is now the "polar opposite" of what the audience has seen in her first appearance in the Marvel Cinematic Universe.

"Her life is full of intimacy and relationship, and she also has all the success she ever dreamed of and the super-suit," Lilly added. "I mean, nothing can touch her at this point, she's like on top of the world."

Aside from the first installment of "Ant-Man," the character also appeared in 2018's "Ant-Man and the Wasp" and 2019's "Avengers: Endgame."

She will now return in "Ant-Man and the Wasp: Quantumania," which is scheduled to release on Feb. 17.

Marvel Studios dropped a new trailer for the upcoming installment that teased a brutal fight between Ant-Man a.k.a. Scott Lang (played by Paul Rudd) and supervillain Kang the Conqueror (played by Jonathan Majors).

It will be the first movie to release in Marvel Cinematic Universe's Phase 5. Helmed by Peyton Reed, the movie features Bill Murray, Tony McCarthy, Samuel L. Jackson and Randall Park.
