S01 | EP 13 The Hunter

During a routine job in a small town neighborhood, a flea E.V.O. that Rex was in the middle of curing is destroyed by Hunter Cain, a Punisher-styled vigilante who uses an advanced weapon known as "Sweet Caroline" that causes targeted Nanites to self destruct. Hunter claims that Providence has been lying to the public for years and that the E.V.O. Crisis isn't caused by nanites in every form of life on the planet but in fact a disease that spreads from person to person. Six is able to prevent a fight from breaking out between Rex and Hunter and when they get back to Providence, Hunter's back story is explained. He went insane several months ago when his wife went E.V.O. and whom is the one he first euthanized. Six cites Hunter as a threat because of his rallying of the public against Providence. Meanwhile Rex has lost his will to fight E.V.O.s after a accident in which he was attacked by civilians and injured one by mistake. Meanwhile a large amount of phantom like E.V.O.s are on a rampage at the docks and are immune to conventional weapons. Hunter and his private army arrive on the scene with their specialized anti-nanite weapons and are able to fight off a large amount of the phantoms. Rex, having finally regained his belief in humanity, arrives to fight the phantom E.V.O.s and is attacked by Hunter. While the two are alone, Hunter reveals that he spent a fortune cloning a lone phantom E.V.O. to create the small army to prove Providence's ineffectiveness (not knowing a news team had captured his admitting the crime). After a rough battle, Rex ties up Hunter and leaves him for Providence and, with the help of Hunter's not so loyal army, Rex is able to kill off the phantom E.V.O.s. The episode ends with dozens of interviews about how Rex saved lives while at least partially repairing his reputation and strengthening his new-found belief in humanity, but knows that another person like Hunter will take his place.
