I'm glad someone asked about 'Elite' because there are a few book series with that name and I can never be sure which one people mean. You're probably talking about the Spanish TV series 'Elite' on Netflix? If so, the key characters are from different social classes clashing at Las Encinas, this super exclusive private school. The core trio from the working-class background are Samuel, Nadia, and Christian, who get scholarships after their public school collapses. Their arrival disrupts the wealthy students like Guzmán, his sister Marina, and their friend Polo.
Guzmán starts off as this arrogant, entitled rich kid, but his role is really as a catalyst for conflict and, later, unexpected growth, especially in his relationship with Nadia. Marina's role is more tragic; she's the center of the mystery in Season 1, the one whose murder everyone is trying to solve. Polo, along with his friends Cayetana and Valerio in later seasons, represents a different kind of privilege—old money with deep, hidden dysfunctions. Then you have characters like Ander, the son of the school principal, whose role often ties the friend groups together through his relationship with Omar, Nadia's brother.
It's hard to pin down just a few because the cast rotates so much each season. New faces like Patrick, Mencía, and Ari get introduced as older characters leave, constantly shifting the dynamics. The most consistent role might be Samuel's—he's often the moral compass, the one seeking justice and truth, even when it gets him into trouble. But honestly, half the fun is watching how their roles get subverted; the 'nice' characters make terrible choices, and the 'villains' sometimes earn your sympathy.
