Moonlighting

Noah convinces Rex to enroll in his High School, Benjamin Franklin High, to compete in the Ping Pong tournament, Noah's three previous partners having been hospitalized in practice matches against a team from another school which Rex discovers is a pair of twins named Gabriel and Michael, who have turned E.V.O. and been fused together into a Two-Headed E.V.O. (with the right head being Gabriel and the and the left head being Michael). At the school, Rex is actually enjoying being around other kids who virtually worship Rex and Noah since they are on the Ping Pong team which they take way too seriously. Noah lies about Rex being a foreign exchange student from a school run by "Principal Haha".

Rex does surprisingly well on a Trigonometry Pop Quiz given by Mr. Buchiner which has a reputation to give even the Principal nightmares. During the tournament, the Twins father and Coach pushes them way too far, going so far as to use the same technology Mouse used in "Lost Weekend" on the twins causing them to grow four extra arms and go on a rampage. Rex deciding the well being of the audience and twins takes precedence over the tournament goes to fight and calm down the twins. During the fight, Rex and the twins smash into Mr. Buchiner's classroom, where he helps Rex by pointing out he can use the floorboards as a catapult, launching the twins back to the stadium. When Rex leaves Mr. Buchiner goes back to grading papers and talking about wanting a pony. Using their father as a distraction Rex is able to short out the amplifying patches returning the twins to their previously mutated state, unfortunately Rex informs the Twins that they're incurable.

Rex chews out the coach for his reckless endangerment of his sons and both boys informs their father that they don't even like Ping Pong and would rather take piano lessons instead. With that the Coach decides to get them a piano teacher, enter them into a piano tournament, and make the lot of them proud. The principal however informs Rex for the destruction that Rex caused he's expelled. At Providence, Rex informs Dr. Holiday that he actually enjoyed his one week at school, which Dr. Holiday decides is a good thing since she believes she has been lenient in her tutoring of Rex making him also take History, Spanish, Trigonometry, and Science from her as well. The stylized epilogue shows that Noah's Principal met "Principal Haha," Mr. Buchiner gets his pony, the Twins live out their dream as a piano player making their father proud, and Rex is still being put through Dr. Holiday's tutoring.

Rex is 15, and like most 15-year-old boys, he likes cars, girls, music and sports. But unlike most 15-year-old boys, he can make his fists the size of boulders, sprout a jet pack out of his back and turn his legs into a lightning-fast motorcycle. These talents are extremely useful to Providence, a global organization chartered to fight mutant creatures known as E.V.O.s (Exponentially Variegated Organism). Rex is under their care and is their ultimate weapon.

Generator Rex takes place in the aftermath of a global accident, where microscopic machines known as nanites have merged with every living thing. For a select few, the nanites mutate their hosts into monstrous creatures called E.V.O.s.

Rex is one such E.V.O., but unlike the monsters he and Providence battle, Rex has control over his nanites. He alone has the ability to not only control these nanites- allowing him to create amazing mechanical limbs and gadgets that aid him in battle ' but also heal E.V.O.s of their mutation.

Rex's powers are incredible, and his importance to Providence and the world is undisputed. But on top of that, he just wants to be a normal teenager and must balance his adrenaline-fueled adventures with the everyday ups and downs of being 15. Rex is joined by a team of characters including his sidekick, a highly intelligent monkey named Bobo Haha who encourages Rex's mischievous side; his mentor Agent Six, so called for being the world's sixth deadliest man; the brilliant Dr. Holiday, who seems to be the only one that really understands Rex; and Noah, a regular kid and Rex's friend.

Rex's greatest threat is an E.V.O. named Van Kleiss, who with his minions called The Pack sees the nanites and resulting E.V.O.s as part of a greater plan and the future of humanity.
