|
Five years ago, an unexplained accident results in the spread of billions of incomplete microscopic nanites into Earth's atmosphere. The nanites infect all living things and randomly activate, causing some organisms to mutate into Exponentially Variegated Organisms, or EVOs. In response to the Nanite Event, an international organization known as Providence is formed to contain the EVO threat. Rex, a 15-year-old boy, is an amnesiac EVO in Providence's custody who can control nanites, allowing him to both cure some E.V.O.s and manipulate his own nanites to form biomechanical weapons from his body. Under the supervision of Agent Six and Providence head scientist Dr. Rebecca Holiday, Rex deals with E.V.O.s around the world, curing as many as he can. Tiring of Providence's control over his life and poor treatment of him, Rex sneaks out of their headquarters with his EVO chimpanzee friend Bobo and meets Noah Nixon, an ordinary teenage boy whom he befriends. The two are then attacked by a group of E.V.O.s who pull them through a portal to Abysus, an E.V.O.-infested Eastern European country, where they meet Van Kleiss, the EVO leader of Abysus with the ability to manipulate its environment. Van Kleiss explains that Abysus was the epicenter of the Nanite Event, and heavily implies that he knows Rex and that he was involved with the events leading to the Nanite Event. Van Kleiss then attacks Rex, revealing that he feeds on fresh nanites. Rex escapes, and Agent Six arrives to rescue the group, with Van Kleiss seemingly being killed but later regenerating his body. Later, at the Providence HQ, Six and Holiday promise to treat Rex better and help him uncover his past, and Noah is revealed to be secretly working for Providence's leader, White Knight, to spy on Rex. | ||||||||

After Agent Six nearly kills a priest-turned-EVO whom Rex cures at the last moment, Rex becomes conflicted about Providence's ruthless "cure, contain, or kill" policy. Rex, Six, and Bobo are then sent to Manhattan, which has become infested by zombie-like E.V.O.s controlled by an EVO named Peter Meechum. Deeming the spread of Dr.Meechum's control too dangerous to contain, White Knight initiates Bleach Protocol, ordering for a nuclear weapon to be detonated on the Manhattan Bridge to kill Meechum and the infected. Refusing to let New York be destroyed, Rex learns that Meechum's daughter, Sarah, has been kidnapped by Van Kleiss and is being used as leverage to force Meechum to take over Manhattan. Meechum agrees to cooperate with Rex, and Rex cures him, along with the other infected individuals. Rex then rescues Sarah and reunites her with Meechum, who is placed under protective Providence custody. | ||||||||

Rex, Noah, and Bobo take a "vacation" to the resort island of Cabo Luna behind Providence's back, where Rex develops a crush on a mysterious girl named Circe. Hearing a strange noise at night, Rex encounters Circe under attack by a huge EVO sea monster. Helping her defeat it, Rex learns that Circe is herself an E.V.O. with the ability to summon other E.V.O.s with a sonic scream, and summoned the sea monster as part of an initiation ritual to join the Pack, the followers of Van Kleiss. Six arrives and helps Rex fight the Pack, but when Rex tries to convince Circe to leave the Pack and join Providence, she refuses, explaining that the Pack are the only ones who accept her for what she really is. Circe accompanies the Pack to Abysus, while Rex reluctantly returns to Providence to drown his sorrows in his work. In Abysus, Van Kleiss forgives Circe for her failure, as he intends to use her blooming romance with Rex to get to him. | ||||||||

| A spider-like EVO escapes special containment in Providence's headquarters, prompting Dr. Holiday to place the entire base on emergency lockdown. Rex and Noah, trapped inside of the Petting Zoo (Providence's containment zone for E.V.O.s), work together to evade the EVO until a panicked Noah inadvertently lets slip that he was hired by White Knight to spy on Rex. An outraged Rex loses access to his powers, and Noah is captured by the spider EVO. Rex and Holiday reach the center of the Zoo, where the EVO has captured a number of Providence agents and Noah and placed them in webbed cocoons. Holiday then reveals that the E.V.O. is her younger sister who, unfortunately, cannot be cured by Rex. Rex and Providence are able to subdue and recapture the EVO, and Rex makes amends with Noah. Rex threatens to hunt down White Knight if he ever tries to deceive him again, then flees Providence, while Six takes responsibility for revealing the truth about Noah. | ||||||||

| While running away from Providence, Rex encounters and aids a group of engineers under attack by EVOs. As thanks, the engineers lead Rex to their village, which is hidden from the world by a cloaking field. One of the engineers, Jacob, explains that the community consists of engineers who lost work after the Nanite Event, and are led by a man named the Architect who is building a tower capable of communicating with nanites on a global scale. While he grows fond of the community and their acceptance of him in contrast to Providence's coldness, Rex becomes suspicious of the Architect and investigates his tower, learning that he is in fact an android controlled by a malevolent artificial intelligence called Zag RS. Zag RS reveals that she intends to destroy all nanites, and all living things in the process, using the communications tower. Rex exposes the Architect's true nature to the townsfolk, and together, they are able to deactivate the tower and seemingly destroy Zag RS. Rex then returns to Providence, on the condition that he, Bobo, Six, and Holiday have meals together every Friday, like Jacob's family. | ||||||||

When Rex awakens from the procedure, he finds Six, Bobo, and Holiday missing, and encounters the Pack outside subduing them. In the base, Rex is betrayed by Providence scientist Weaver, who is revealed to have been supplying his nanites to Van Kleiss. Rex finds the others, and they confront Weaver and the Pack, with Weaver unleashing Rex's excess nanites to scare them off. In the process, Weaver is mutated into a massive EVO. Rex tries to cure him, instead finding himself communicating with the nanites inside of him and experiencing flashbacks of his past. Six defeats Weaver, and Rex is taken to Purgatory Base, located on a remote desert island in the South Pacific, to offload the remainder of his nanites. As Rex walks off to explore the island with Bobo, Six and Holiday privately discuss Rex's nature. | ||||||||

Van Kleiss and the Pack arrive without warning at the Headquarters of the United Nations in New York City, where Rex is forbidden from attacking him due to Van Kleiss possessing diplomatic immunity as the leader of Abysus. Van Kleiss claims he has come to deliver a speech to the United Nations delegates on Abysus' behalf, but Providence remains suspicious of him. Rex is invited to a party by Van Kleiss, which he attends with Six, Bobo, and Holiday. At the party, Rex encounters his friend Circe in an underground passageway, where Breach, one of Van Kleiss's followers, is using her powers to teleport soil from Abysus to New York, thus granting Van Kleiss his full power. Van Kleiss takes the U.N. delegates hostage, but Rex is able to defeat him by blowing a hole in the underground passages and causing them to be flooded by the East River. Rex prepares to kill Van Kleiss, but Van Kleiss reminds him that he knows the identities of his parents, causing Rex to hesitate long enough for him to escape. | ||||||||

Holiday, who has Breach in custody, demands that she reveal Rex's location. Rex, meanwhile, explores the abandoned town and learns that he is in Greenville, Ohio, which Holiday says disappeared without a trace two years prior; they conclude that Rex has been trapped in a pocket dimension created by Breach, who is keeping him there as her newest "doll". Realizing that the pocket dimension is a source of comfort and security for Breach, Rex is able to drive her to despair by wrecking all of her other "dolls" until she releases him and seemingly explodes. Later, Rex expresses sympathy for the loneliness that Breach must have felt and finds a new appreciation for what he has. | ||||||||

| Providence investigates a series of attacks on wealthy individuals carried out through mysterious boxes which temporarily mutate the victims into EVOs. They trace these boxes to Dr. Gabriel Rylander, a nanorobotics expert who went missing during the Nanite Event. Learning that Rylander had a son, Rex suspects that he may be his father, and accompanies Six, Holiday, and Bobo on a mission to South America to find Rylander. At Rylander's compound, they encounter Van Kleiss and the Pack, who are there in search of an allegedly limitless supply of nanites. Rex enters the compound and meets Rylander, who explains that he is not Rex's father, but rather the one who named him; Rex's family worked on the original Nanite Project which developed the nanites. After a near-fatal accident, Rex was infused with experimental nanites to save his life, which gave him his powers. The individuals Rylander attacked were the ones who initially commissioned the project, and were targeted as a warning as to the consequences of not finishing their work. Rylander reveals that Rex has a living brother, and injects Rex with an unknown nanite. Before Rylander can tell Rex the full truth about his past, however, he is stabbed by Van Kleiss. Rex and Van Kleiss battle until Rylander manages to push Van Kleiss into a nanite reactor, seemingly killing them both. | ||||||||

Rex, Six, Holiday, and Bobo travel to Abysus and find the landscape wasting away, and encounter Circe and the Pack, who explain that Van Kleiss's death has caused the unstable nanite-infused environment of Abysus to come undone. They claim that the only way to reverse the process is via a machine built by Van Kleiss, and Rex reluctantly agrees to help them after Dr. Holiday mentions the risks of allowing the corruption of Abysus to continue. However, Rex backs out after discovering that the machine is designed to resurrect Van Kleiss. The room then floods with nanite ink that begins to drown everyone, forcing Rex to activate the machine and bring back Van Kleiss, who refuses to save Rex's friends until he promises to join him. Rex agrees, and Van Kleiss releases the others. Rex reluctantly shakes Van Kleiss's hand, but realizing that Van Kleiss's new nanites have been altered, he successfully cures him.

After Dr. Holiday falls asleep as well, Rex is joined by White Knight himself in a massive battle suit, and the two close in on "Patient Zero", the source of the virus. When White Knight attempts to kill Patient Zero, he and Rex come at odds and then battle. White Knight reveals that he is the only pure human left on Earth, lacking any nanites in his body, and thus cannot turn into an EVO. Rex defeats Knight, but both are then attacked by a monster made of the virus. Rex is able to cure Patient Zero by entering the monster, and humanity is awoken from the virus.

On Rex's "birthday" (the anniversary of when he joined Providence), Agent Six reflects on the day he first met Rex. Years prior, Six and White Knight are partners working for Providence during its early days. During a battle against a gigantic mechanical EVO in Mexico, the EVO explodes and Six discovers a young Rex in its fist. After learning that Rex can cure E.V.O.s, Six secretly brings him to Providence and shows him to then-research assistant Dr. Holiday. White Knight, discovering Rex's nature, orders that he be dissected using a machine that magnetically strips nanites from a host body, killing the host. Six and Knight battle over Rex, and in the process, White is trapped inside of the machine and nearly killed until Rex deactivates it at the last moment. As a result, White Knight is stripped of all nanites but left alive, and is chosen to lead Providence as the only human on Earth who cannot turn into an EVO. White Knight reluctantly allows Rex to stay at Providence, but warns Six to kill Rex should he ever show signs of turning into the giant EVO again. In the present day, Six gifts Rex with a tantō, a ceremonial samurai blade, marked with a symbol of loyalty, stating that the two of them will follow the same path. | ||||||||

Van Kleiss and the Pack orchestrate a massive coordinated attack on all major Providence facilities on Earth, with Van Kleiss himself targeting the Keep, the aerial flagship of Providence. Rex, Noah, and Bobo attempt to stop Van Kleiss from taking over the Keep, but Van Kleiss captures Rex, revealing that some of Rex's nanites were left behind when he cured him, giving him knowledge of Rex's abilities. Van Kleiss then steals all of Rex's active nanites, restoring his EVO abilities and leaving Rex powerless. Van Kleiss's lieutenant Biowulf throws Rex out of the Keep, but Rex is narrowly rescued by Holiday. Van Kleiss then discovers that Rex's nanites have given him the ability to turn living things into EVOs, and he proceeds to mutate all of the Keep's crew, including Captain Calan. At the Providence HQ, Holiday discovers that Rex still has one active nanite - the mysterious and infinitely powerful Omega-1 Nanite which Dr.Rylander injected him with some weeks ago. Van Kleiss then rams the Keep into Providence HQ, and his EVOs swarm it. In a desperate move, Rex travels to Purgatory Base and fills himself with deactivated nanites, hoping the Omega-1 will control them. Van Kleiss and his allies have defeated Agent Six and the rest of the agents, but Rex is able to defeat him with a new and much stronger and effective weapon the Omega-1 generated. Although Van Kleiss escapes, Rex is confident that he can defeat him next time. | ||||||||

Meanwhile, a mechanical entity escapes from the portal and attacks Six, placing him in a coma. Rex blames Ben for Six's injury and captures him, but Ben escapes, subsequently realizing that he is no longer in his own world. The two reluctantly agree to help each other just as Caesar arrives. Caesar reveals that the entity that escaped the portal is Alpha, a prototype nanite AI that he developed during the Nanite Project with the intent of enabling nanites to control themselves. When Alpha became self-aware and attempted to assimilate living things, Caesar developed a device to send it to an empty dimension where it would do no more harm. However, Ben recognizes that Caesar instead sent Alpha to the Null Void, a pocket dimension used as a prison for alien criminals, and was thus responsible for bringing Ben into Rex's universe. Alpha continues to grow in strength by assimilating more living things, until Rex, Ben, and White Knight confront it in the Bug Jar, where it has absorbed all of the resident EVOs.

Black Knight launches an assault on the Providence defectors' base to capture the remaining two Meta-Nanites. During a confrontation with Rex, Black Knight reveals that she herself is an E.V.O. with the same powers as him; she was a test subject during the Nanite Project, and was turned into an E.V.O. after Rex as an "improved version". Providence captures Rex and his team, but Van Kleiss reveals that Rex has the fifth and final Meta-Nanite inside of him, preventing Black Knight from killing him. Rex is transported to the laboratory in Abysus, where Caesar reveals that the only way to safely remove the fifth Meta-Nanite from Rex is to place him inside of the machine that will insert the other four Meta-Nanites into the Consortium. The Consortium and Rex enter the machine - along with Black Knight, who demands the position after threatening the Consortium - resulting in the Meta-Nanites being unexpectedly split between Black Knight and the Consortium members, transforming them into E.V.O.s with mighty reality-warping, elemental and teleporting powers. Angry at the flawed results of the experiment, the Consortium take out their anger on Rex, until Providence suddenly intervenes, with White Knight having returned as leader. Providence evacuates Rex, and they begin plans to fight back against the Consortium. The Consortium begin to sew chaos across the world, using their powers to pursue personal vendettas and greed. Faced with this threat, Six reveals to Rex the existence of his full bio-mechanical E.V.O. form, which may be powerful enough to stop the Consortium, but could also result in him losing his memories. After contemplating this, Rex finally confronts the Consortium, just as they are attempting to redo the experiment to gain the full power of the Meta-Nanites. Rex enters his full E.V.O. form but is defeated by the Consortium, but retains his memories. The Consortium restart the process, but Van Kleiss betrays them, revealing that he has retained his sanity and has always intended the power of the Meta-Nanites for himself; he strongly implies that he killed Rex's parents after they tried to stop him. Van Kleiss activates the process, but it fails, and his arm is destroyed. Caesar reveals that his late parents secretly programmed the Meta-Nanites to work only for Rex, preventing them from being used by anyone else. Rex absorbs the combined Meta-Nanite and becomes all-powerful. He spontaneously cures every E.V.O. on Earth, then permanently deactivates the Meta-Nanites, not wanting to abuse their power. In the aftermath, Providence continues its work to investigate and perfect nanites. Caesar, Gabriel Rylander, and Peter Meecham begin working together on a new project, and Rex is reunited with Circe and his friends, all of whom have returned to their human forms. Black Knight and the Consortium escape to an unknown location, while Breach takes Van Kleiss and the Pack away through her portals. The series concludes with Rex continuing his work for Providence to protect the Earth as the last and strongest E.V.O. on the planet. | ||||||||||||||
