Santiago is a member of the Volturi guard, and one of few members who does not possess a supernatural capability. His only useful skills come from his superior physical strength.
In Breaking Dawn, when Irina reports to the Volturi about an immortal child being created by the Cullen family, the entire coven travels to Forks to destroy them. Therefore there is no doubt that Santiago is among them during the confrontation. Throughout the entire confrontation, he remains in the shadows, waiting for the opportunity to attack the Cullens with the rest of his coven. After the situation was resolved peacefully, he retreats to Volterra with the coven.
In Breaking Dawn - Part 2, he personally escorts Irina to the Volturi leaders' chamber. In Alice's vision of the probably battle, Caius orders Santiago to hunt down Renesmee and Jacob, who run across the forest to escape their slaughter. He quickly catches up to them, but is killed by Jacob when he bites off his head and escapes with Renesmee. Since the battle is avoided, Santiago's death is also prevented.
Other than that he was brawny and huge-looking, Santiago's physique was never fully described in the books.
In the movie, however, he displays a bulky body shape with dark-colored skin, and black dreadlocks that run down to his neck. Since he drinks human blood for a living, his eyes exert the traditional red color of human-feeding vampires that darken the longer he abstains from feeding.
He wears the traditional black and gray outfit of the Volturi's guards, and has pierced ears.
Powers and abilities
Similarly to Felix, he is not supernaturally gifted but rather possesses tremendous physical strength and combat skills that surpass regular vampires. Though he is not quite as skilled as Felix, he is not to be underestimated.
In the movie he is shown to be a very fast vampire; he quickly catches up to Jacob and Renesmee whilst chasing them across the forest despite the two of them having a headstart.
