The Thirteen Origins is a series of one-shot origin stories for the members of The Thirteen, a group of Mexicans and Mexican Americans who discover they are chispas, able to wield impossible powers. On his eighteenth birthday, martial arts champ Bruno Vega discovers that-like his great-grandfather before him-he can fly and detect corruption in human souls. He adopts the moniker of "Zopilote"-vulture-and fights in Mexico City to protect the innocent and the weak from being harmed by both criminals and the authorities. "Perseverance is rooted in hope" is his guiding philosophy, and it gets the attention of the mysterious Father Tonal, who recruits Bruno to attend a very special college, where he and other chispas can hone their abilities.
