Milly Alcock’s Supergirl: A Playful Yet Complex Introduction
In Superman, Milly Alcock’s Supergirl makes her first appearance during a scene set in the Fortress of Solitude. As Indulgexpress reported on July 13, 2025, the scene is both comedic and heartfelt.

This light-hearted interaction showcases the playful chemistry between the Kryptonian cousins while hinting at Kara’s deeper emotional struggles.
Director James Gunn has described this version of Supergirl as “a bit of a mess,” shaped by the trauma of witnessing Krypton’s destruction. Alcock’s brief screen time effectively conveys a character who is both flawed and endearing, setting the stage for the complexities that will be explored in her standalone film.

Gunn revealed that Ozu served as the physical model for Krypto, with his own pet videos inspiring the dog’s movements.
In the movie, Krypto is revealed to be Supergirl’s pet, adding another layer of connection between the cousins. The unruly dog, who first appeared in DC Comics in 1955, plays a pivotal role in the story and is expected to have an even larger presence in Supergirl: Woman of Tomorrow.
