1	1	"The Day That Everything Changed"	Sam Montes	Man of Action	April 23, 2010[1]	693-001
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 has the ability to control nanites, allowing him to both cure some EVOs 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 EVOs 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 EVOs who pull them through a portal to Abysus, an EVO-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 Rex killing Van Kleiss during their escape, but Van Kleiss regenerates 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.
2	2	"String Theory"	Rick Morales	Man of Action	April 30, 2010	693-002
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 EVOs controlled by an EVO named Peter Meechum. Deeming the spread of 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.
3	3	"Beyond the Sea"	Chris Graham	Man of Action	May 7, 2010	693-003
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 EVO with the ability to summon other EVOs 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. In Abysus, Van Kleiss forgives Circe for her failure, as he intends to use her to manipulate Rex.
4	4	"Lockdown"	Sam Montes	Scott Sonneborn	May 14, 2010	693-004
A spider-like EVO escapes from 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 EVOs), 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 EVO is her sister, and 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.
5	5	"The Architect[2]"	Rick Morales	Amy Wolfram	May 21, 2010	693-005
While running away from Providence, Rex encounters a group of engineers under attack by EVOs, and helps them. 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.
6	6	"Frostbite[2]"	Chris Graham	Marty Isenberg	May 28, 2010	693-006
After absorbing too many nanites from an EVO and entering critical condition, Rex is taken to the remote Paradise Base in Antarctica for an emergency offload of his excess nanites. 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 a Providence scientist named Weaver, who is revealed to have been supplying Rex's excess 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 excess 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's 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 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.

Rex wakes up in a creepy boarding school in an empty town with no memory of how he got there. Contacting Dr. Holiday, Rex learns that he was attacked suddenly by Breach, who teleported him away to an unknown location using her power to create trans-spatial portals. 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," including a variety of hostile EVOs, 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.
9	9	"Dark Passage"	Sam Montes	Marsha Griffin	June 18, 2010	693-010
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, with Rylander targeting them 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.

However, when a seemingly unstoppable swarm of ghost-like EVOs attacks Providence, Rex decides to intervene. Cain attacks Rex, and reveals that he cloned the EVOs as a "demonstration" of the futility of Providence.

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 successful 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 EVO 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.

After learning that Rex has the ability to cure EVOs, 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.

Gatlocke realizes that the convoy was actually transporting the toilet paper as a ruse, and Rex's truck is the one with the actual nanites. Gatlocke and Rex encounter each other and battle, all while Rex tries to keep the nanites from going above sea level, as Six warned that doing so would make them "go off."

Van Kleiss then steals all of Rex's active nanites, restoring Van Kleiss's EVO abilities 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 Omega-1 nanite which Rylander injected him with.

Rex deduces that the source is Zag RS, who survived reentry in their previous encounter in space, and is now attempting to destroy all nanites using the storm. Van Kleiss reveals that Rex's Omega-1 nanite can self-replicate, creating new nanites, and Rex uses this knowledge to fight back against Zag RS until Van Kleiss deactivates her and vanishes. Zag RS is taken into Providence custody, and Caesar reveals that he originally designed her to eliminate stray nanites, and that her voice is that of Rex's mother, Violetta.

In the present day, Rex tracks down Van Kleiss to Paris, learning that the device he built was not a time machine but a storage chamber which preserved only his nanites, meaning he was aware of every single second that passed. Rex frees Van Kleiss from the machine, and confronts the entity, revealed to have been Breach, who was pulled along with Van Kleiss during his trips through time due to the machine he attached to her.

			Chris Graham	Rob Hoegee	January 3, 2013	694-060
Black Knight launches an assault on the Providence defectors' base in order to capture the remaining two Meta-Nanites. During a confrontation with Rex, Black Knight reveals that she herself is an EVO with the same powers as him; she was a test subject during the Nanite Project, and was turned into an EVO 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 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 EVOs with reality-warping 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 to his role as its 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 unstoppable powers to pursue personal vendettas and greed. Faced with this threat, Six reveals to Rex the existence of his full EVO 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 in order to gain the full, limitless power of the Meta-Nanites. Rex enters his full EVO 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 the Meta-Nanites were secretly programmed by his late parents to work only for Rex, preventing its purest form from being used by anyone else. Rex absorbs the combined Meta-Nanite and becomes omnipotent. He simultaneously cures every EVO on Earth, then permanently deactivates the Meta-Nanites, not wanting their immeasurable power to ever be abused again. In the aftermath, Providence continues its work to investigate nanites. Caesar and the Nanite Project scientists begin working together on a new project, and Rex is reunited with his Circe and his Hong Kong friends, all of whom have returned to their human forms. Black Knight and the Consortium escape to an unknown location, while Breach appears and takes Van Kleiss and the Pack away through her portals. The series concludes with Rex continuing his work for Providence to protect the Earth.
