Reality TV fans, get ready for Fox’s latest who-sung-it series, “Alter Ego,” which premieres September 22, 2021. The original music competition program tasks up-and-coming singers with performing their hearts out on the big stage, only with a twist: they don’t perform as themselves. Instead, the contestants appear in front of a panel of judges as animated avatars, fictionalized dream versions of themselves. In other words, think of “Alter Ego” as if “The Masked Singer” and “Avatar” had a baby. The aspiring artists range in age from 17 to 60 and hail from all parts of the United States, from Los Angeles to New York and everywhere in between. Meet the cast of Fox’s “Alter Ego” show, including the judges and contestants of Season 1, by scrolling through our photo gallery below.
