New spoilers for the "Supernatural" spin off show, called "Supernatural: Tribes," are here! Find out who the main characters for "Supernatural: Tribes" will be, and learn more about the spin off show based in Chicago.

The main characters' descriptions reveals some spoilers for the spin off: there will be an "epic battle involving five rival monster families and a vengeance-seeking hunter," TVLine reports.

Here are the details, via TVLine:

ENNIS ROTH: The de-facto star of the potential series, Ennis is "likeable, strong-willed, resolute, with a strong sense of justice." He's the son of a cop who grew up in poverty. He's en route to the police academy himself when someone he is close to is murdered - presumably by some kind of monster. He meets up with Sam and Dean and "learns the staggering truth" that Chicago is run by five families of monsters (including, but perhaps not limited to, werewolves and shape shifters). And with that, a new monster-hunter is born. Fun fact: Producers are looking to fill this role with an African-American actor in his early 20s.

DAVID HAYDEN: A shape-shifter from one of Chicago's ruling monster families. He's been living as a human for some time, but a tragedy propels him back into the life. David is in his early 20s.

MARGO HAYDEN: David's "professional, strong-willed, determined, ambitious" shape-shifter sister. She's an "ex-punk rocker gone corporate" who sets out to be the new head of the family in the wake of a tragedy. Margo is in her early 20s.

VIOLET DURANT: A werewolf and part of the wealthy, powerful Durant family. In a twist right out of West Side Story, the early-twentysomething is hot for family rival David (see above), but their love is forbidden.

JULIAN DURANT: Violet's "savagely handsome, strong, arrogant" twentysomething brother and Ennis' arch nemesis.

FREDDIE COSTA: A world-weary copy in his 30s, Freddie has a soft spot in his heart for Ennis (he knew his dad back in the day). Fun fact: Freddie's got a secret.

According to the Huffington Post, executive producers Jeremy Carver and Robert Singer told Entertainment Weekly that the characters from "Supernatural: Tribes" will be introduced during "Supernatural" season 9, episode 20, which will air later this spring.
