Cast and characters
Stephen Moyer as Reed Strucker: A father of mutants trying to balance his family responsibilities with his job as a district attorney. It is later revealed that Reed is a mutant with the ability to generate and manipulate energy, as well as disintegrate matter. Moyer said of the character, "He thinks he's doing the right thing by moving [the mutants]. He does know these camps aren't particularly nice. He knows a few people he's captured have disappeared. He also knows this could happen to his kids. He has no choice but to go on the run."
Amy Acker as Caitlin Strucker: A mother and nurse struggling with her "increasingly challenging" teenage children. Showrunner Matt Nix said that though Caitlin does not have mutant powers, she is not "just a mom" or "just the doctor" in the series, and "over the course of the show I really love the idea of showing the evolution of a suburban mom into an underground warrior."
Sean Teale as Marcos Diaz / Eclipse: A rebellious mutant who can absorb and manipulate photons. Eclipse was rejected by his human parents, and grew up smuggling drugs from Mexico to the United States. The mutant underground uses him to smuggle mutants to safety in Mexico. The character was created for the series, but has had his powers compared to Sunspot and his personality to Wolverine and Havok.
Natalie Alyn Lind as Lauren Strucker: One of the series' central children, a "perfect" kid. Her mutant power allows her to create force fields by pushing together molecules of air or water.
Percy Hynes White as Andy Strucker: One of the series' central children, a sensitive loner who keeps to himself. His mutant power is a form of telekinesis, being able to pull things apart at a molecular level with his mind.
Coby Bell as Jace Turner: A man struggling with the cold-blooded requirements of his job. Turner is a Sentinel Services agent, trying to find the Struckers and the other mutants. Nix said the character is "more than just a villain hoping to round up every last superpowered human," but is instead trying to balance protecting society with taking away the rights of mutants.
Jamie Chung as Clarice Fong / Blink: A "sarcastic, lively" mutant with teleportation powers. An "independently minded" member of the mutant underground, Blink begins the series using her abilities as "a way out of situations she doesn't want to be in", but her abilities and relationship to them evolve throughout the series. Chung wears heavy-duty contact lenses to portray Blink's mutant green eyes, and also has pink markings on her face.
Blair Redford as John Proudstar / Thunderbird: A strong-willed mutant possessing superhuman strength, durability, enhanced healing and superhuman senses. He is leader of the underground community. Nix said the character is "dealing with his own issues of feeling the weight of thousands of years of Apache history and mutant history and an obligation to both families."
Emma Dumont as Lorna Dane / Polaris: A brave and loyal mutant whose abilities include controlling magnetism. She is introduced as being "unstable" due to bipolar disorder. Nix explained that, within the series, there is "some awareness" that Polaris is the daughter of Magneto, leading to the question "does she accept the mantle of her birthright? Is it her job to be Magneto in his absence?" The character is depicted with green hair, as she is in the comics, but "subdued shades of green".
Skyler Samuels as the Frost Sisters: Esme, Sophie, and Phoebe Frost are telepathic triplets with their own agenda, separate from those of the mutant underground, Sentinel Services, and Trask Industries. The effect of the three characters together was created with a mixture of effects: split-screening, green-screening, and face replacements over doubles when Samuels worked with two other actresses portraying the other sisters.
Grace Byers as Reeva Payge: Leader of the "Inner Circle" with an elite band of followers who is introduced in the second season. She possesses destructive sonic powers.
