Zack Calderon as Rafael Garcia
A quiet, sensitive teenager who lives in Tijuana but attends high school in San Diego. Straddling two worlds has made it difficult for Raf to get a clear and certain sense of himself, so he gravitates toward people with stronger, charismatic personalities.
Charles Alexander as Kirin O'Connor
Kirin is a short-tempered lacrosse player who doesn't have much patience for weakness. Among the castaways, he's ready and willing to take the lead first, though his hot-headed approach might not appeal to everyone.
Miles Gutierrez-Riley as Ivan Taylor
Ivan is an activist and aspiring playwright with an impeccable fashion sense and a razor-sharp wit. But his words can be cutting, sometimes too deeply, which has cost him friends along the way.
Tanner Ray Rook as Bo Leonard
Bo is a soft-spoken, contemplative teenager, also from the Florida panhandle. He has a naively optimistic outlook on life, despite a difficult upbringing and he'd gladly lie down in the street for his best friend Scotty. His loyalty knows almost no bound.
Aidan Laprete as Henry Tanaka
The opposite of his personable stepbrother Seth, Henry is an emo reclusive type who prefers to retreat into the safety of his noise-canceling headphones and dwell on the darkness in the world.
Nicholas Coombe as Josh Herbert
Josh is a talkative, hypochondriacal teenager from a wealthy family in San Diego. Unlike the rest of his athletic, tennis-playing family, Josh is an awkward, nervous type who takes a number of homeopathic supplements to handle his chronic stress.
Reed Shannon as Scotty Simms
Scotty is short in stature but big in personality. He's a fast-talking teenage entrepreneur from the Florida panhandle who dreams of making the Forbes 400 list one day. And by his side always, both in life and on the island, is his best friend Bo.
Alex Fitzalan as Seth Novak
Seth is naturally funny, Ivy-League smart, and full of charisma. Though he doesn't necessarily aspire to a leadership role, his steadiness and sense of humor win him the respect and loyalty of the others, except for his stepbrother Henry.
