Lost Weekend

Rex is sent on a mission to fix the Bug Jar shield. Van Kleiss comes to recruit the vengeful E.V.O, No-Face in the Bug Jar. When Rex finds out that the Pack is there along with Circe, he follows them wearing a stealth suit. He is discovered by Biowulf and Rex is saying how Biowulf is now becoming a henchman (as opposed to his previously right-hand man... wolf). Rex is knocked out by Circe after they have an argument. Rex is now taken into a stadium where he has to fight No-Face, very much to Circe's shock and horror. While fighting No-Face, Van Kleiss is saying, to a very shocked and horrified Circe, how they need Rex alive, but do not need him to have his brain working, although this angers No-Face who commands the E.V.O.s to attack the Pack. When Rex escapes and goes to the control shield room to find Bobo still holding on a lever (cause Rex said if he let go the machine would "go boom"), which he didn't need to anymore. The shield goes down and they both leave the room in the sewer and find Circe waiting for them and help them round up the E.V.O.s.

When Circe, who finally sees Van Kleiss for what he truly is, uses her ultrasonic sound abilities to summon and lure all the E.V.O.s with her hypnotic siren-like melody. She soon becomes tired and has to rest for a bit while the spellbound E.V.O.s come toward them. When it seemed that they could not keep on going Biowulf comes and saves them and orders Rex to fix the shield generator. Rex fixes it and only has a minute to get out of reach of the shield. He transforms into his Rex Ride and tells Bobo to get on board with Circe, and asked if Biowulf was coming which he rejects with saying they tell no one he helped them. They barely made it out with the back of the bike broken off barely missing Bobo. Rex tells Circe that now she can make her own choices now that she doesn't need Van Kleiss any more. Bobo gives her a Providence bike to use, and Rex tells her that "Hong Kong is nice this time of year" (reference to Rabble). She still neglects to join Providence and goes off on her own, while Rex drives back to base, Bobo rubs it in that he still didn't get a date with Circe.

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.
