While David Corenswet's debut as the Man of Steel in 2025's <em>Superman</em> will no doubt be exciting, he's not the only confirmed hero who will be introduced in the very first DCU movie. The Justice League International looks to be involved with characters such as Guy Gardner's Green Lantern, Mister Terrific, Hawkgirl, and Metamorpho. Beyond Superman himself, I'm very excited to see how Metamorpho will be translated into live-action. Played by Anthony Carrigan, Rex Mason aka Metamorpho can transmute his body into several elements and form them at will. As such, this will be a fascinating power to see on-screen.
