Santana

Betrayed by his own kind and abandoned for dead on a desert planet, the protagonist fights predators for his life and becomes stronger and more dangerous than ever. The galactic mercenaries who hunt him turn out to be pawns in a grand plan for revenge. With enemies appearing in his path whenever he needs them, he begins his quest for vengeance.

Santana plays the archetypal antagonist—a cocky and ruthless bounty hunter who underestimates his opponent and pays for it with his life. His character highlights the protagonist's skill and survivability, contrasting the professional with the overconfident amateur.
He is also the head of the hired killers.
