An animated series from the creators of ''WesternAnimation/{{Ben 10}}'', premiered on Creator/CartoonNetwork on April 23, 2010. The plot and characters are based on a two issue comic book, called ''M. Rex''. When ManOfActionStudios decided to turn this into an animated series, the title had to be changed to ''Generator Rex'' when they found out that ''M. Rex'' was already trademarked.

The plot focuses on a 15 year old boy named Rex, who gains the ability to produce bio-organic machines from his body due to an accident called "The Event", that spreads nanomachines called [[{{Nanomachines}} Nanites]] all over the world and causes random mutations in people, animals and plants. The central story is based around the organization called Providence that is tasked with the job of protecting civilization from the mutants called E.V.Os. Rex is used by Providence because of his ability to control his Nanites to produce machines from his body to fight the E.V.Os and cure them of their mutations so they can go back to being regular functioning members of society.

Due to Rex's mysterious past involving the initial outbreak of the Nanites he has amnesia and works with providence while trying to uncover what really happened to cause the event and his abilities. Rex is hunted by an evil scientist named [[BigBad Van Kleiss]] who has connections to The Event and is trying to capture and use Rex for his own means. Rex is assisted by his talking chimp, lazy, wisecracking E.V.O sidekick and a mysterious Providence agent named Agent Six.

Like all of Man Of Action's shows ''Generator Rex'' normally does not take itself seriously even when dealing with very serious subjects, such as the theme of people not being very fond of Providence, their methods and lack of transparency sometimes taking it to extremes such as creating their own E.V.O hunting groups and outright attacking Rex due to him being an E.V.O and his "messy" way of dealing with E.V.Os. Rex often does not listen to his superiors - especially not to the head of Providence, White Knight. Instead, Rex decides to run away and try to spend as much of his life as he can as a normal teenager but seemingly normal situations often lead to altercations with E.V.Os.

The show had a notable Crossover episode with Ben10UltimateAlien in the form of a special titled Ben10GeneratorRexHeroesUnited.

Has a CharacterSheet [[Characters/GeneratorRex right this way.]] And a {{Recap}} page [[Recap/GeneratorRex here]].

After three seasons the storyline concludes with the 2-part special "End-Game". An [[BonusEpisode unrelated one-shot]], "Rock My World", was released out of order afterwards.

The complete series, including the BonusEpisode, is available on iTunes and Creator/{{Netflix}}.
---------------
!!''GeneratorRex'' contains examples of:
[[foldercontrol]]

[[folder:A-E]]
* AbortedArc: [[TheBlank NoFace's]] ramblings about "the before".
** The before might be the Providence Agents who crashed earlier in the episode, or the people who were evacuated when the city was contained.
** Things have continued on from "Written In Sand" as if the episode never happened. Rex isn't wary of [[spoiler:Cesar]] and [[spoiler:ZAG-RS]] isn't seen or mentioned ever again.
*** [[spoiler:ZAG-RS]] had been around since early in the series; her death/reboot effectively ''ended'' her arc. As for [[spoiler:Cesar]], his questionable actions and motivations have been a plot point since his introduction. (See the notes for "Black and White" under WhamEpisode, below -- not to mention the episodes right after the time skip).
** Quarry showed up with some Providence Tech used to control EVOs (It's unknown how he got them, he may have stolen them, or Providence secretly gave it to him to test out), and caused lots of chaos. After the tech is destroyed, Rex states that it was lucky they stopped the menace. At the end of the episode, a warehouse is shown with hundreds of mind control devices, foreshadowing an entire army under providence, not just domesticated, but under direct control. Nothing ever comes of this revelation, because the series ended.
* AccidentalPublicConfession: [[spoiler: During "Black and White" Black Knight tells White she'd betray The Consortium without a second thought. White makes sure to record her saying this, keeping it as a trump card.]]
* ActionGirl: This series gives both genders time to shine, even if the men ([[TheWorfEffect excluding Bobo]]) have a better overall record, due to their lion's share of front-line fighters.
* ActionSurvivor: By "Badlands", Noah surely counts.
* AdaptationExpansion: The original comic was only two issues long and never really got off the ground.
* AIIsACrapshoot: ZAG-RS, a reoccurring computer program villain, [[spoiler: is a pre-Nanite Event computer that was created to destroy all escaped Nanites. Naturally, this would kill every living thing on Earth except White Knight]].
** Alpha, the BigBad of the ''WesternAnimation/{{Ben 10}}'' {{Crossover}} "Heroes United", [[spoiler:is a Nanite with the same ability to control other Nanites as Rex, and like ZAG-RS also wants to destroy the world.]]
* AHouseDivided: [[spoiler: John Scarecrow attempts to pull this on Rex, Holiday and Six after stealing information from them for New Providence. He actually succeeds.]]
* AlliterativeName: Subverted and lampshaded by Rex. Due to a bit of confusion, Rex briefly assumes Rylander is his father. When Rylander tells him this isn't the case, Rex decides this is probably for the best, as "Rex Rylander" is a silly name.
** Played straight with Noah Nixon.
* AllYourBaseAreBelongToUs: [[spoiler:Episode 21 in its entirety.]]
* AllJustADream: [[ZigZaggingTrope Zig-zagged]] in "Frostbite".
* AllOfTheOtherReindeer: Rex gets this treatment in the first episode after he stops giving people free stuff from vending machines.
* AlmostKiss: Between Rex and Circe. [[spoiler:Six and Holiday get one in "Family Holiday".]]
* AmbiguouslyBrown: Six was Asian in the M-Rex comics, Holiday is often headcanon'd as Asian, and Breach's original name was "Ting-Ting".
* AmbiguouslyGay: Gatlocke. Effeminate, and continuously repeats how he ''really loves'' Rex.
** He made it pretty clear that he "loved" Rex's powers, and was jealous. [[HoYay Still...]]
* AndIMustScream: [[spoiler: Van Kleiss in his hibernation chamber. Hundreds of years passed every time he used it (for a total of about 4000 years), and he was aware during every second of it.]]
* AndTheAdventureContinues: [[spoiler:The [=E.V.O=] threat may be over, but the world still needs a hero.]]
--->'''Rex:''' There's always going to be something, isn't there?
--->'''Six:''' Yes, there is.
* AnimalWrongsGroup: The Green Fist. Bobo even refers to them as "People for the Ethical Treatment of [=E.V.O=]s."
* {{Animesque}}: While it has the art design of shows like ''WesternAnimation/{{Ben 10}}'', the concept itself coupled with the action camera work and look of the characters themselves favor past and present anime more than a bit.
** The plot is also similar to ''Manga/{{Parasyte}}'', ''Manga/{{Guyver}}'' and arguably ''Manga/EatMan''.
** The ArtShift in Rex's flashback in "Double Vision" cranks this UpToEleven.
* AntiVillain: Garan-Set, who just wanted to [[FishOutOfTemporalWater things just like they used to be in his time]]. Even Rex has sympathy for him.
* AppleOfDiscord: Van Kleiss tries this on [[spoiler:Rex in regards to his recently-discovered brother. Seems to have worked, at least a little.]]
** Possibly subverted, as subsequent events made it so that one of the victims could only benefit from the gambit. [[spoiler: Van Kleiss sowing suspicion on Rex's part may have prepped him to take Cesar's eventual betrayal in stride.]]
* ApocalypseHow: A Class 0, with millions dead worldwide after The Event. And, [[FridgeHorror in thesis]], it could escalate all the way up to a Class 4 - maybe even Class 6 - [[ParanoiaFuel at any moment]].
* ArsonMurderAndJaywalking: At the end of "Rock My World", Rex lists the crimes Sebastian will be charged with:
-->"Attempted murder, assault and battery, construction without a permit..."
* ArtShift: The "Where Are They Now" montage at the end of "Without A Paddle" is done in a cartoon-ier style than the usual show.
** A bit of exposition in "A Brief History of Time" is conveyed through graphic novel-style stills.
** Rex's struggles with a recalcitrant bull in "Hermanos" are depicted in chibi-style art.
* AsceticAesthetic: Providence are big fans of this, in contrast to the various gribbly weirdnesses they battle.
* AsYouKnow: The second season opener pretty much spells out the first season finale in a couple of minutes, just in case you forgot or just started watching.
* AxCrazy: Breach, Breach, and, oh yeah, Breach.
** Biowulf also counts, strangely enough. Whenever he has a run-in with Rex or anyone else from Providence, the first thing he does is resort to violence. Check out how he freaks on Bobo when the Pack comes to New York. At this rate, it actually seems like ''Skalamander'' is the most stable member of the pack (if one doesn't count Circe). I mean, at least Skalamander tried to talk things out with Rex by saying "hey, we're on your side" before everything falls apart, in contrast to Breach or Biowulf.
* AsideGlance: In "Badlands", when Rex tinkers with the radio and a song by Orange (the band that made the ''Generator Rex'' theme song) starts playing, Bobo looks directly at the audience.
* BackFromTheDead: [[spoiler:Van Kleiss]], in episode 15. Oh, don't act surprised.
** It was actually more surprising that [[NighInvulnerability it took him this long]].
** [[spoiler:Rex himself, in the following episode.]]
** [[spoiler:Rylander]], who went with [[spoiler:Kleiss]], gets this treatment. [[spoiler:Kind of.]]
* BackToBackBadasses: Rex and [[spoiler: [[EnemyMine Van Kleiss]]]] in "Written in Sand". Also lampshaded.
-->'''Rex''': Back to back!
-->'''[[spoiler: Van Kleiss]]''': What?
-->'''Rex''': Back to back! Haven't you ever read comic books?
* {{Badass}}: Pretty much everyone on the show, from the agents to the scientists to the talking chimp and even [[BadassNormal Noah]].
* BadassAndChildDuo: Six and Rex were temporarily a prime example of one before Rex discovered his powers, as seen in a flash back in in "Promises, Promises".
* BadassBoast: Oso, the South American Providence agent, gets snared with bolos around his arms, he declares them to be toys and attacks.
* BadassBookworm: Cesar.
-->'''Hunter Cain:''' Who're you? An E.V.O?
-->'''Cesar:''' No. I'm a scientist.
** More notably, Holiday, who, despite mainly being in a 'mission control'/scientist role, can throw down like the rest of them if needed.
* BadassNormal: Six definitely qualifies
** As well as his four other numbered counterparts
* BadIsGoodAndGoodIsBad: Rex invokes this on Robo Bobo to be more like the real Bobo in his titular episode, but Robo Bobo exaggerates it in order to cause trouble.
* BashBrothers: Rex and Six.
* BatmanColdOpen: Used almost as frequently as the TropeNamer.
* BatmanGambit: Primary tactic used by [[ChessMaster Van Kleiss]].
** Rex pulls off one in "Alliance," even getting [[BaddieFlattery complimented on it]] by Van Kleiss.
*** As of "Black and White", White Knight has joined the club.
* BeachEpisode: In episode 3, they head to Cabo Luna, which Bobo describes as the greatest place for spring break... and bikini babes.
* {{Beat}}: Right after Noah asks Rex if he would rather hide from a giant bunny than go on a date.
* BetrayalInsurance: White Knight uses a mechasuit when he is forced to leave his sanctuary in Providence to help Rex with a world wide problem. Rex realizes that the suit was in fact originally designed to take ''him'' out if he ever went rogue on Providence.
* BigBad: Van Kleiss in the first and second seasons, Black Knight and the Consortium in the third.
** BiggerBad: The Consortium, who are behind Providence and have their own agenda.
* BigBrotherInstinct: Cesar.
* BigBrotherMentor: Re does this alot, the episode "Lions and Lambs" comes to mind.
* BilingualBonus: In Episode 2, "String Theory", the kid who trys to stop Rex is speaking fluent Latin American Spanish while in the season 2 premiere, Rex is seen watching a Mexican soap opera during his downtime.
* TheBlank: No-Face.
* BlessedWithSuck: E.V.Os in general. Those that turn are lucky to be anything more than feral monsters, even luckier not to be BodyHorror-incarnate, and before Rex would have just been captured and vaporized for study. After, they may not be curable by Rex. For bonus points, there's a small but noticeable amount of FantasticRacism that goes with the territory. Even Rex, who has the most stable batch, has frequent memory loss.
** Though there ''are'' some E.V.Os with complete control over their abilities and subvert this trope.
* BigApplesauce: Episodes 2 and 7, the latter focusing on the area around the United Nations building.
* TheBigDamnKiss: Between Circe and Rex in "Assault on Abysus". [[spoiler:Right before she lets herself get captured in order to save him.]]
* BigNo: By ZAG-RS in episode five.
* BigRedButton: Used by Holiday in "Double Vision" to fry some EVO vines.
--> '''Holiday:''' Always go for the big red button... [[spoiler: unless you don't want to drain the batteries to zero]].
* BlackAndGrayMorality: Van Kleiss is your garden variety [[CardCarryingVillain Card Carrying]] EvilOverlord. Providence is mostly staffed by well-meaning and good-hearted people, but its [[JerkWithAHeartOfJerk obnoxious]] [[WellIntentionedExtremist leader]], [[FantasticRacism White]] [[KnightTemplar Knight]]...
** While White Knight has redeeming factors, his hands-off superiors are borderline villains.
** Later gets into GreyAndBlackMorality when [[spoiler: Black Knight replaces White Knight]]. Policy changes from "Cure, Contain, or Kill" to "Cure or MindRape into obedience". And that policy goes for any employees who won't get with the program.
* TheBladeAlwaysLandsPointyEndIn: Six's [[{{Hammerspace}} sleevespace]] blades tend to do this.
* BlindingBangs: Breach
* BlondGuysAreEvil: Bobo jokingly says this of Noah in "Guy vs. Guy". There is a certian slug girl from "Breach" who tried to kill Rex. Roswell from the Consortium counts too. Weaver from "Frostbite". Braden Moses from "A Family Holiday".
* BloodFromTheMouth: Briefly seen on White Knight in "Promises, Promises". Also happens to Van Kleiss in "Leader of the Pack", when Rex punches him ''without using his powers.''
* BodyCountCompetition: Rex and Bobo have one in "The Swarm".
* BodyHorror: Lots of it. Some of which is actually quite surprising for a show on the Cartoon Network (at least on its kid-friendly hours).
* BondVillainStupidity:
** Lampshaded and averted in "Payback" by Biowulf. When Rex is BroughtDownToNormal and Biowulf is told to get rid of him, Biowulf goes for the nearest airlock. When asked if a more elaborate death trap would be more appropriate, Biowulf simply says "No" and drops him.
** Played straight by White Knight in the same episode. He traps Biowulf in an electromagnet, which could rip the Nanites right out of his body if it were set at maximum. When Biowulf asks why he didn't just do that, White Knight, having donned his PoweredArmor, more or less kicks him in response. He just wanted a good fight.
* BonusEpisode: The last episode of the series aired was "Rock My World", which doesn't really have anything to do with the overall plot. However, it seems that the producers realized it would be the very last episode instead of "End Game" and threw in an AnimationBump, AwesomeMusic original to that episode, some light {{Fanservice}} by bringing back Holiday's little sister, and crafted the plot to be just 22 minutes of [[CrowningMomentOfAwesome Rex being awesome]] to let the series end on a high note.
* BookEnds: The series begins with Rex diving out of a airship to attack a giant EVO. The final scene mirrors this, except against a giant robot.
* BootCampEpisode: In "Basic", Rex and Noah agree to go through Providence basic training to prove they are tough enough to make it.
* BottomlessMagazines: The non-energy firearms are shown to spit out an obscene amount of spent shells, but we rarely see anyone reloading. Also, the magazines themselves are ludicrously tiny.
* BreatherEpisode: Episode 20, "Badlands," taking place between the heavy Almost-WholeEpisodeFlashback "Promises, Promises" and the [[WhamEpisode epic]] episode "Payback."
** Most of the episodes centering Rex and Noah count as this.
* BroughtDownToNormal: One of Rex's powers is to do this to other E.V.Os, but subverted since it only works if they are mindless or want to be cured. If they want their mutation, they can resist. Animals are also harder to cure. Some are also simply incurable, and thus can only be killed or contained.
** Rex spends most of "Lockdown" with his PsychoactivePowers on the fritz. [[spoiler:Happens more literally in "Payback", when Van Kleiss steals his Nanites. Fortunately, all it accomplished was a DiscardAndDraw.]]
** In "What Lies Beneath" [[spoiler:Rex cures Van Kleiss. It doesn't last long, and Van Kleiss comes back with a vengeance and obtains [[DiscardAndDraw arguably even more dangerous]] (and certainly [[GeniusLoci less geographically limited]]) powers.]]
** In "Payback" [[spoiler:Van Kleiss figures out a way to cure Rex by taking his Nanites to become an evil opposite to Rex, while Rex is just a teenager now. Naturally it doesn't last.]]
** A completely different case in "A Family Holiday" where [[spoiler: Holiday's sister, Beverly, formerly an ''incurable'' E.V.O, gets turned back to an average human teenager.]]
** Yet again in "Deadzone", due to a nebbishy fellow who functions as a PowerNullifier.
** [[spoiler:"End Game" has a WorldHealingWave do this to virtually every EVO on the planet. Bobo, Van Kleiss and the Pack, and the Consortium are likely the only living [=EVOs=], not counting Rex himself.]]
* BubbleBoy: Or rather man. White Knight lives in a hermetically-sealed room to keep him nanite-free, since he's the only trustworthy leader of Providence (no random mutation).
* BullyingADragon: A large crowd harasses Rex in "The Hunter" because they learned he was an E.V.O from the news. Never mind that said news spot is him fighting ''a giant monster''. Taken to [[TooDumbToLive suicidally insane levels]] when Rex gets tired of their crap and brings out the {{Power Fist}}s to scare them off, only to accidentally backhand someone when the crowd doesn't back down. ''Despite this'', they just get more violent. It's hinted that it might have been a set-up to make Rex look bad, however, so it may be justified.
* ByTheBookCop: Six. However, he'll make [[PetTheDog exceptions]] if the orders are jackass-y enough.
* ChekhovsArmoury: The first SeasonFinale. In order to fight off the Pack, [[spoiler: we have White Knight's PoweredArmor, Dr. Holiday's E.V.O sister, and most importantly, the nanite that Rylander injected into Rex halfway through the season. On the other side, Van Kleiss is able to carry out the attack in part because Rex cured him a few episodes earlier.]]
* ChekhovsGun: The [[spoiler: earplugs]] in "Rock My World."
* ChessMotifs: White Knight [[spoiler: being replaced by Black Knight.]] Lampshaded even by Rex in "Back in Black" when he fights [[spoiler: Providence's new elite black pawns.]] Even more justified in [[spoiler: "Endgame" after White Knight took back Providence, while the black pawns still remain loyal to Black Knight]]
* ChickMagnet: Rex has managed to attract his fair share of women. Too bad the only ones he has a chance with are the one he ignores and the one [[DatingCatwoman working for the enemy]].
* ClockRoaches: Van Kleiss believes he's being pursued by one in "A Brief History of Time". [[spoiler:It turns out its a formless Breach, who keeps getting pulled to Van Kleiss due to her time travel rig being connected to his nanites. Rex manages to restore her physical form and remove the machine.]]
* CloseCallHaircut: A variation happens with Agent Six's tie in the premiere.
* CodeEmergency: Rex has problems keeping his codes straight. He once tells some friends not to worry as it's "only a Code 2". When a giant EVO crashes through a building, he remembers that "the lower the number, the '''worse''' the situation".
* ColorCodedForYourConvenience: Rex's original weapons (the Boogie Pack, the Smack Hands, etc.) are colored orange, grey, and silver, but his new makes, [[spoiler:which are centered around Rylander's control nanite]], are blue and black.
* ConspicuousCG: The spent shells from Providence's automatic weapons are the most obvious example. Some vehicles may be animated using computer generated imagery, especially in scenes where the plot requires many identical vehicles at once.
* ContinuityNod: A couple in "What Lies Beneath", to events from the first and ninth episodes.
** "Basic" featured captured E.V.O specimens from all throughout the series, used for practice at Providence's basic training facility. These included Weaver from "Frostbite", and a gluttonous businessman who was captured while attacking a grocery store. Finally explaining what's done with incurables who are too big and/or too dangerous to keep in the Zoo.
** Rambaur from "Basic" appears in "Moonlighting", albeit with a few extra pounds.
** A big point of "Alliance" is fixing the ForceField around the Bug Jar from "The Forgotten", and at the end, Rex advises [[spoiler: Circe]] to head to Hong Kong, ''a la'' "Rabble".
** "Grounded" brought back the teenagers from the first episode, as Noah's Jerkass classmates.
** In "Enemies Mine" when Gatlocke is interviewing a kid to join his gang he asks ''"by the way can you fly"'' because as we found out in "Badlands" that is the major difference between him and Rex.
* ContrivedCoincidence: Breach, in the episode that bears her name, dropping the smashed ice-cream trucks directly on top of the giant scorpions that were menacing Six and Bobo. What are the odds?
* CoolOldGuy: Agent Martello in "Outpost".
* CoolOldLady: Abuela, Rex and Cesar's adopted grandmother, in "Night Falls". She faces off against Hunter Cain without batting an eye.
* CoolShades: Agent Six. Rex's goggles may also count.
* CoolSword: Never mind Rex's BFS; Six owns a pair of [[KatanasAreJustBetter katanas]] that fold up to store in his sleeves, with a spring-launch for easy access. They can even be snapped together to form a car-lifting electromagnet.
** Let us not forget, the things are springloaded to ''work underwater''. Through a wet suit. Yeah.
* CrapsackWorld: As cool and fun as Rex's adventures may appear, the fact that every single living thing on the planet has been infected with Nanites and could potentially mutate into a hideous abomination at any time, without any warning or knowledge of what they could turn into, makes it a rather bleak place to live for your average person. What's worse, while Rex may be able to cure E.V.Os, it doesn't work with all of them, so those who mutate may never turn back. On the bright side, things seem to have improved somewhat from the flashback scenes in "Promises, Promises", since at least now people who turn have a chance of being cured, and it really looked like humanity might just outright go extinct before Rex.
** [[spoiler:Then there's Kiev, Ukraine. When the event happened, the unlucky bastards living there were hit with the single largest concentration of Nanites (because Earth's magnetic field funneled a huge amount to it). The whole city went E.V.O, and lacking the resources to deal with the problem (Providence didn't even exist), the world decided to do the only rational thing: put a giant spherical containment field around that hell-hole and never speak of it again.]]
*** On the bright side, [[spoiler:Alpha kills everything there and absorbs their Nanites in "Heroes United". It's "just" a ghost town now.]]
* CrazyPrepared: White Knight's MiniMecha and PoweredArmor (yes, he manages both at the same time) ''will'' have a weapon for the situation, and ''will'' keep him safe from Nanites. Period.
** Really, Holiday? You either had ready, or set up in under 8 minutes, an interrogation room with hand scanners, trapdoor, decending [[BuffySpeak wall-thingy]], Breach-sized restraints, and PROBE CANNON?
* CreatorCameo: ManOfActionStudios' founders had two. The teenagers who teased Rex in the first episode and return in the episode "Grounded" are modeled after and voiced by them. They even lampshade it by calling themselves "The Men of Action".
* CreepyChild: One of Breach's "dolls". [[spoiler:The fact that she isn't laughing at Rex's jokes is, according to him, a clue that she's an E.V.O. Which she is. Oh so much.]]
* {{Crossover}}: One with ''WesternAnimation/Ben10UltimateAlien'', entitled "Heroes United."
* CryptidEpisode: In one episode, the creature turns out not to be an EVO but is instead a (perfectly natural) chupacabra.
* CureForCancer: The nanites.
** The nanites could be the cure for ANYTHING: Cancer, AIDS, genetic malformations, lost limbs, you name it. That would be of course if they had actually been finished before The Event
* CuteAndPsycho: Breach has characteristics of this. She also likes cute, shiny things... and then there's her "dollhouse".
* CuteMonsterGirl:
** Breach, of course.
** While the vast majority of E.V.Os tend to be slavering monsters that look like they just left a BodyHorror pageant, Cricket from "Rabble" manages to mutate into a fairly attractive cricket-hybrid. She easily stands out in comparison to her companions, a [[{{Cthulhumanoid}} squid-faced guy]] and [[{{Mummy}} living mummy bandages]].
* DarkerAndEdgier: In the first episode alone, [[spoiler:we get to see a small army of dead {{Red Shirt}}s, and the hero actively try to ''kill'' the BigBad]]. Rex himself also isn't as squeaky clean as other Man Of Action heroes, demonstrating selfish and utterly reckless behavior.
** The series was already pretty dark but, from season 2 onward the series is just getting darker as it goes along with the [[MindRape treatment of evos]], [[CategoryTraitor Rex being a traitor to his own kind]], [[GoodIsNotNice a new even more unfriendly Providence with the new leader Black Knight]], and [[BiggerBad Providence's higher ups being revealed as]] [[AGodAmI having not so noble intentions]].
* DarkMagicalGirl: Circe.
* DatingCatwoman: Rex and Circe. [[DeconstructedTrope This show demonstrates why it is BAD.]]
* DeadpanSnarker: Circe, Bobo Haha, Six, and sometimes Rex.
** Add the Russian scientist Volkov to the list in "Gravity".
** White Knight as of "Plague".
* {{Determinator}}: One, the most dangerous man in the world. With nothing more than sheer mental strength and his techniques, he resisted losing himself to his E.V.O transformation for five years.
* DiplomaticImpunity: Van Kleiss arrives at the UN as a representative of Abysus in episode 7. It's safe to say he lost it by the end.
* DiscardAndDraw: Rex and Van Kleiss do this to each other. Rex takes Kleiss' powers, so Van Kleiss steals Rex's powers. Rex takes in some unprogrammed Nanites, which are then programmed by Rylander's injection to give him a new powerset, as well as getting the old ones back.
* DownerEnding: Combined with DownerBeginning and a HopeSpot for good measure. [[spoiler:In "Assault on Abysus", Rex's old crew in Hong Kong appears to be captured wholesale, except for Circe. She goes to Rex, then joins him in a mission to Abysus, which is now under Biowulf's control and serves as a safe haven for Evos who don't want to be controlled by Providence. Providence attacks and they manage to hold their own, then Black Knight corners them anyway. Circe, Biowulf, and Skalamander are all caught, and Rex is the only one to make it out.]]
** [[spoiler:Rex's old crew managed to escape, so that at least is a plus.]]
* DrillSergeantNasty: Though lacking the actual rank, the drill instructor in "Basic" qualifies. As an example, he randomly throws a flash-bang at Rex and Noah for poor marksmanship.
* DynamicEntry: The KillerRabbit in "Operation: Wingman" tackles Rex from off-screen no less than four times.
* DysfunctionJunction: Six is the closest thing Rex has to a proper father. Which makes Doc Holiday his "mom". His mom who he has been known to ''hit on''
* EliteMooks: Black Knight's Providence ninjas.
* EmergencyTransformation: Implied to have happened [[spoiler:with Rex. Rylander claims that Rex had an accident and an alternate nanite strain (not the worldwide unstable kind) was used to save him]].
* EnemyMine:
** Happens briefly and reluctantly in "What Lies Beneath" with the Pack and Rex. Then again in "Written in Sand" between Rex and Van Kleiss.
** Providence and White Knight's splinter group have been forced into teaming up in numerous episodes.
** "Enemies Mine", obviously, though not how you'd think. [[spoiler:Gatlocke, Valve, Hunter Cain, and No-Face team up to kill Rex. Rex calls Hunter out on teaming up with an Evo.]]
* EpicFail: Said word for word by Rex to Van Kleiss in "Payback". And to Breach in "Hard Target."
* EvenEvilHasStandards: Gatlocke.
-->'''Gatlocke:''' For us there are no rules.\\
'''{{Mook}}:''' Except no cursing...\\
'''Gatlocke:''' [Angrily grabs Mook, then a {{Beat}} and grins] ...True. We're anarchists, not animals.
* EveryCarIsAPinto: In "Deadzone", Rex and company attempt to escape from Providence at an airport by stealing a mobile stairway. The mobile stairway explodes when it crashes into a hanger wall.
* EverythingsBetterWithMonkeys: Bobo Haha, Rex's sidekick. Specifically, he's a grizzled, [[EyepatchOfPower eyepatch-wearing]], gun-toting, ''[[DeadpanSnarker snark-talking]]'', monkey sidekick.
** Actually he's a chimp... There must be a trope based on this misunderstanding.
* EverythingsBetterWithSpinning: Several of Rex's powers invoke this trope. Being PsychoactivePowers, it could be seen as FridgeBrilliance; Rex is the kind of guy who would see spinning things as cooler.
* EvilBrit: Van Kleiss
* EvilCounterpart: After Kleiss steals Rex's Nanites, he becomes this to Rex. Rex can cure E.V.Os, while Kleiss creates them.
** Further more, Van Kleiss controls nature; while Rex's powers are all technology based.
** [[spoiler: As of End Game: Part 1, Black Knight appears to have gained all of Rex's powers...just eviler.]]
* EvilIsNotWellLit: [[spoiler:Black Knight's office.]]
* EvilOnlyHasToWinOnce: Ever since the meta-nanites have been introduced [[spoiler:special nanites which can bestow the power over things like matter, antimatter and the like]], if the Consortium ([[spoiler:Providence's higher ups who [[AGodAmI intend to use them and become gods]]]]) or [[spoiler:Black Knight who intends to acquire their power for herself]], gets their hands on them it's game-over. However, it is revealed in the finale that [[spoiler:the meta-nanites were programmed to work only for Rex, so Black Knight's or the Consortium's efforts to gain their full power were actually futile from the start]].
* EvilSoundsDeep: The Black Pawns.
* ExactWords: "I said the Keep is returning to Base. I didn't say we'd be ''on'' the Keep."
* {{Expy}}:
** Rex could be considered one for Jaime Reyes, the third Blue Beetle from DC Comics, though it's mostly based on the fact that theyr'e both hispanic teenagers with machine-based superpowers.
** His character design (especially [[IconicOutfit the memetic red jacket]])is very similar to [[NoMoreHeroes Travis Touchdown's]], his mechanisms have a similar aesthetic to Travis' Beam Katanas, and they have very similar thrillseeking personalities (ignoring Travis' bloodlust and perversion, thankfully). His design and powers are also reminiscent of [[WesternAnimation/{{Ben 10}} another]] [[WesternAnimation/Ben10AlienForce Man of Action]] [[WesternAnimation/Ben10UltimateAlien character]]. His powers are also similar to [[VideoGame/{{Prototype}} Alex Mercer]].
** Breach might make one think "[[TheRing ...Sadako?]]"
** Van Kleiss is possibly an expy of X-Men's Magneto. They're both {{Well Intentioned Extremist}}s with a QuirkyMinibossSquad of super-humans trying to destroy humanity before they destroy them.
*** Or [[SelfDemonstrating/DoctorDoom Doctor Doom]], considering he's a [[MagnificentBastard Magnificent]] EmperorScientist with diplomatic immunity and a penchant for time travel.
*** Pale skin? Long, dull black (SkunkStripe not withstanding) hair? Needs to kill other super beings to survive? Nigh Immortal sans one glaring weakness? Pedophile undertones? [[ArsonMurderAndJaywalking Squarer chin than most villains?]] [[Manga/{{Naruto}} All he needs is a snake motif and he'd be Orochimaru.]]
*** Alternatively, he can be seen as a {{Dracula}} expy with his lethal feeding method, high resistance to killing, and need of his native soil to survive.
** Agent Six looks dangerously close to Agent Smith from the Matrix with a dash of TheMenInBlack as mentioned above, and also looks like he was [[http://www.invaderzim.tv/images/characters/bill.jpg transplanted]] from ''InvaderZim''. This one might reflect TheMenInBlack having an "anonymous" look though.
*** [[http://farm4.static.flickr.com/3206/3080121296_a0b5bd3f82_o.png He also resembles]] [[WesternAnimation/TeenageMutantNinjaTurtles2003 Agent Bishop]], another [[TheMenInBlack Man in Black]].
** The Bunny E.V.O. Well, considering it's a bunny with a vicious streak and a nearby soldier, when it's first seen, comments that "That is no ordinary rabbit!" in a British accent. Well, [[Film/MontyPythonAndTheHolyGrail it doesn't take a genius to figure it out]].
** Five is pretty much completely [[Anime/{{FLCL}} Haruko]] with a Cockney accent.[[/folder]]

[[folder:F-J]]
* FacelessGoons: Ironically, it's the good guys that use this trope, being a large organization. The BigBad has a QuirkyMinibossSquad. They're making an effort to subvert it by introducing a couple of [[MauveShirt recurring grunts that occasionally show their faces]]. Played straight and justified moreso now that Providence has become corrupt under Black Knight's leadership.
* FaceHeelTurn: Subverted. In "What Lies Beneath", Van Kleiss blackmails Rex into doing one by threatening to suffocate Six, Holiday, and Circe. Rex agrees... so Van Kleiss will let Rex get close enough to cure him.
* TheFaceless: The leader of the [=E.V.Os=] from the Bug Jar, [[spoiler: previously know as Kiev, Ukraine]] and the main villain of episode "Forgotten". And he's called [[ExactlyWhatItSaysOnTheTin NoFace]].
* FakeInTheHole: In "Badlands", Rex throws a can of soda at Gatlocke's gang; pretending it's a cannister of unstable nanites.
* FalseFlagOperation: Hunter Kain buys a batch of cloned E.V.Os, releases them to prove Providence is worthless, then has his men save the day. Except he cloned so many that their special E.V.O-killing ammo ran out, and Kain wrote them off since he was too busy fighting Rex. Rex, of course, saves the day.
** The scientist from episode 36 does something similar. He says he's made a device that can cure incurable [=EVOs=]. [[spoiler: Turns out he did, but he couldn't complete the last step because 1: he wasn't smart enough, and 2: It wasn't cost-effective. So he made the machine supercharge the nanites of incurables instead, and also implanted some sort of conditioning in them so he could sell them as superweapons to the highest bidder.]] He deserved those punches and slaps Holiday gave him in the episode.
* FamilyFriendlyFirearms: Zig-zagged schizophrenically. On one hand, Providence Soldiers generally use what just about anyone will identify as some sort of machine gun, some of which have what looks like grenade launchers mounted underneath. They have the distinctive muzzle flash, and even eject shell casings most of the time. On the other hand, these guns are referred to as "blasters", and being the RedShirts they are, Providence Soldiers never accomplish anything with them. The presence of microwave energy weapons that actually do something would seemingly make this show a straight example of this trope, except for the fact that they caused their targets, a bunch of giant insects, to explode into a red splatter. Honestly, Generator Rex could get its own folder on this page regarding the degree to which FamilyFriendlyFirearms applies, since the above examples covers about half of the zig-zags the series makes on this trope.
** Also, in another episode, two cops are shown using generic looking automatics with visible shell casing ejection.
** In another, there is a very realistic pump-action shotgun shown being cocked.
* FamilyUnfriendlyDeath
* FantasticRacism: The subject of "The Hunter".
** And loads of it sprinkled liberally throughout the series, running the gamut from simple fear all the way to all-out hate.
** In episode 36, it starts out with the scientist who says he can cure "incurables" averting this trope, insisting that [=EVOs=] (or ones that were human at least) have loved ones and deserve to be cured. He also says that Providence's "military solution" is not the answer, because they're essentially killing people who are sick. It's played straight when [[spoiler: he reveals that he's actually supercharging the EVO's nanites, making them harder to cure, and also conditioning them to be superweapons he can sell to the highest bidder, treating them like animals.]]
* FantasyHelmetEnforcement: Rex has a helmet when riding his hoverbike - but ''not when flying''.
* FertileFeet: Van Kleiss. A rare ''evil'' version of the trope.
* FishOutOfTemporalWater: Garan-Set from "Riddle of the Sphinx". His villainy throughout the episode is nothing more than a twisted attempt to make things the way they were in his time. Rex tries to reach out to Garan-Set when he realizes this and offers to help him adjust. [[spoiler:Garan-Set refuses, believing the world has no place for people like him and Rex, and crumbles to dust as his Nanites break down.]]
* FiveBadBand
** The Pack: A group of powerful E.V.O.s led by Van Kleiss.
*** BigBad: Van Kleiss.
*** TheDragon: Biowulf.
*** TheBrute: Skalamander.
*** EvilGenius / DarkChick: Breach.
*** DarkChick / SixthRanger: Circe.
** The Six: A group of mercenaries comprised of the most dangerous people in the world. [[note]]Their badness is ambiguous, being mercenaries and all, though their willingness to kill seems to point to this direction.[[/note]]
*** BigBad: One (Though it's debatable how bad he was. Turned E.V.O. Deceased.)
*** TheDragon: Dos (The team's current BigBad. His name is Spanish for 2.)
*** TheBrute: Trey (Not actually his real name. Stands for 3.)
*** EvilGenius: IV (Roman numeral for 4. Read as "Ivy".)
*** DarkChick: Five (Despite what her trope implies, is actually quite the opposite of "dark"[[note]]She's bright pink all over.[[/note]].)
*** SixthRanger: Six (Joined Providence to find a cure for the now E.V.O. One.)
* FiveManBand
** Providence: A high tech global military organization dedicated on curing, containing or killing hostile E.V.O.s.
*** TheHero: Rex
*** TheLancer / TeamDad: Agent Six
*** TheSmartGuy / TeamMom (Holiday only) / TheMedic: Doc Holiday, Ceasar
*** TheBigGuy / TeamPet: Bobo (Even though he's shortest member of the team.)
*** TheChick / TagalongKid: Noah
*** SixthRanger / BigGood: White Knight, Ceasar
* FiveRoundsRapid: Mostly played straight with the Providence {{Red Shirt}}s. They tend to stick to shooting things with conventional weapons. Subverted in episode 7 during a fight with a giant worm. When the bullets they have on hand don't work, they call in gunships and tear that thing apart.
** The concept is subverted in "Basic," where one of the {{Mook}}s-in-training realizes that they use FiveRoundsRapid not to kill the E.V.Os, but as a distraction so Rex can deal with them.
* FloatingContinent: The town of Greenville in "Breach".
* FluffyTheTerrible: The MaximumFunChamber full of E.V.O plants and animals is called "The Petting Zoo".
** The E.V.O in "Operation: Wingman" is... a bunny.
--->[[ShoutOut Look, that rabbit's got]] [[Film/MontyPythonAndTheHolyGrail a vicious streak a mile wide]].
* {{Foil}}: TheStoic Agent Six and TheEmpath Doc Holiday.
** Rex's powers are hi-tech hardware, while Van Kleiss has his GeniusLoci GreenThumb.
* FollowTheLeader:
** A show about a young man who gains superpowers and travels the country/world in a team of three, fighting monsters-[[WesternAnimation/{{Ben 10}} hey, wait a minute]]!
** It's made by the same people; looks like they weren't done with making adventures.
** The series main character, his powers and the title may seem rather familiar for anyone who's seen ''GeneratorGawl'', though the overeaching plots of the two series are wildly different.
*** And there are many similarities to [[http://www.firestorm-ink.com/fi_news.html Cybergeneration]] - ongoing global nanotech apocalypse, heavy-handed government agencies, and most of the [=EVOs=] with human intelligence are teenagers.
* ForkliftFu: Noah slams Van Kleiss with one in episode 22.
* FreudianSlip: Noah in the episode "Lockdown". [[spoiler:When in danger of being killed by a spider E.V.O, he accidentally blurts out his affiliation with White Knight, thus forcing him to spill the beans.]]
* FunWithAcronyms: "E.V.O" is short for '''E'''xponentially '''V'''ariegated '''O'''rganism; basically, a living creature that can look like and do any number of things - a living wild-card.
* GameBreakingInjury: White Knight suffers these in pretty much every fight he's in. A single hairline fracture in his faceplate is enough to put him out of a fight entirely.
* GeniusLoci: Van Kleiss's little sanctuary is ''literally'' a part of him. The entire place is seeded with his Nanites. This comes back to bite the team when Kleiss dies; without him around, Abysus' Nanites go out of control and threaten to spread everywhere.
* GettingCrapPastTheRadar: In "Lost Weekend", right before he's about to spew ink at an E.V.O., Skwydd says "payback's a -- ''blehhch''".
* GiantSpider: The main threat of "Lockdown". [[spoiler:Happens to be Dr. Holiday's sister.]]
** Other giant arachnids include the nest of scorpions in "Breach".
** And another spider is seen during the flashbacks in "Promises, Promises".
* GladiatorGames: Van Kleiss is sold into the arena after being captured by the Romans in "A Brief History of Time".
* AGodIAm: The goal of the Consortium.
** Also, Black Knight.
* AGodIAmNot: [[spoiler:Rex in the finale.]]
* GodzillaThreshold: [[spoiler:Rex uses a new version of his HumongousMecha in the finale, despite the fact that it may cause him to lose his memory ''and'' Six is supposed to kill him if he does. Thankfully, Rex turns out fine and even White Knight considers the situation so dire than he revokes the termination order.]]
* GoodIsNotNice: Providence may exist to protect people from E.V.Os, but they are very much a big picture organization. [[WeHAveReserves Soldiers are expendable and are taught as much]], and even Rex, their one method of curing E.V.Os, is at best seen as resource they could do without if necessary. To be more specific, Providence's doctrine is "Cure, Contain, or Kill." Since Rex is currently the only person in the world capable of making E.V.Os revert back to human, the second episode makes it clear [[NukeEm just how far they're willing to go]] if he can't deliver.
** This is especially true as of season three, since [[spoiler: Black Knight has taken over Providence in Rex's absence and White Knight's FreakOut.]]
* GoofyPrintUnderwear: Rex has motorcycles, according to Holiday in "The Swarm".
* TheGlassesComeOff: Played straight and inverted. When Rex puts his goggles on, it's time to kick ass (or do something generally risky). Sometimes, he keeps them on though.
** Six does this, but in a sympathetic reason.
* GogglesDoNothing: Subverted. Given that Rex's powers revolve around heavy machinery, it only makes sense for him to wear goggles.
** They also double as aviator goggles whenever he's riding his CoolBike or flying his jetpack.
** And as of "Double Vision" his new goggles have [[GogglesDoSomethingUnusual several different view modes.]] Infrared, microscopic, and so on.
** Caesar is seen using goggles while working, also in situations where their use makes sense.
* GoneToTheFuture: [[spoiler: Rex, as of "Lions and Lambs".]]
* [[GottaCatchThemAll Gotta Find Them All]]: [[spoiler:The Meta-Nanites. Nanites which possess the dominion code. They possess control over things like matter, antimatter, gravity, electromagnetism etc. and would essentially make the people in control of them Gods.]]
* GrandFinale: "End Game" and "Rock My World". The latter is a BonusEpisode episode that happens to be the last episode aired, but the production team seems to have [[AnimationBump pulled out]] [[AwesomeMusic all]] [[{{Fanservice}} the stops]] to make it end the series on a high note.
* GratuitousSpanish: Letting the audience know that Rex is Latino, he occasionally says things like:
-->'''¡Hola, feo!''' (Hiya, ugly!)\\
'''¡Vamanos!''' (Let's go!)\\
'''¡Belleza!''' (Very pretty!)\\
'''Que pasa, jefe?''' (What's up, boss?)
** Specially [[NonSequiturThud when he gets knocked senseless]]. That is when he goes full Spanish.
** [[LampshadeHanging His brother even finds it amusing when he tries to speak Spanish.]]
* GreatEscape: Valve, Gatlocke, Hunter Cain and No-Face bust out of what is supposed to be TheAlcatraz at the start of "Enemies Mine".
* GroupieBrigade: Rex and Noah get hysterical screaming girls kissing them and tearing off their Letterman jackets when Rex joins Noah's school table tennis team.
** The band [=TrendBenders=] has one in "Rock My World" that become a running gag when Rex has to do security for the band.
* GunsAkimbo: Bobo's and Holiday's attack method.
* HairRaisingHare: When Rex runs afoul of an E.V.O bunny.
* HealingFactor: Rex's Nanites can cure poison and destroy any foreign objects in his body.
* HeelFaceTurn: Kinda-sorta. Circe ''does'' quit the villainous The Pack and cease following Van Kleiss, but she doesn't join Providence, either. Instead, shes joins the rag-tag bunch Rex used to lead in Hong Kong, who are just out to survive... do we have a trope for going from evil to neutral?
* HiddenElfVillage: The village in "The Architect" is protected by a cloaking device.
* HiddenEyes: Van Kleiss' four-armed schoolgirl minion Breach has the typical "black hair covering face" look going. But considering what she is, seeing her face might be more frightening than the four-armed thing.
** Averted. Her face has been seen multiple times now, and she's definitely a CuteMonsterGirl. ''Insane'', but cute.
* HighSchoolDance: Noah ropes Rex into being his wingman for one. Given who [[TheJinx he's paired with]], he was probably safer with the evil rabbit trying to kill him.
* HijackedByGanon: [[spoiler:{{Subverted|Trope}} in the finale. Van Kleiss takes control of the meta-nanite project and combines all of the meta-nanites in himself to become God... but it doesn't work. Turns out the "god nanite" will only work inside Rex.]]
* HisNameIs: [[spoiler: Rylander is impaled by Van Kleiss before he can spill Rex's backstory. While this doesn't kill Rylander, the effect is the same.]]
* HorrorHunger: Van Kleiss has to feed on the Nanites of E.V.Os to survive. The victims of this process are petrified and make nice statues in his garden.
* HotScientist: Dr. Holiday.
* HowDareYouDieOnMe: Dr. Holiday to [[spoiler: Agent Six]] in "A Family Holiday".
* HumanoidAbomination: Van Kleiss gives off this vibe.
* HumongousMecha: Seen in a flashback in "Promises, Promises". [[spoiler: It's Rex.]]
* HunterOfHisOwnKind: Played with and perhaps deconstructed by Rex, whose job it is to stop the very thing he has become. His position as a Providence agent means that other sentient [=EVOs=] are distrustful or even openly hostile towards him. He gets called on this several times.
* {{Hypocrite}}: An old woman, seeking to prove that E.V.Os and humans cannot work together, works with an E.V.O to drive other E.V.Os crazy. She's defeated by Rex, obviously an E.V.O himself, who works with humans. Rex does not hesitate to draw attention to this.
** Hunter Cain is also likely this, he says in the episode he debuted in that he ''created and cloned those [=E.V.Os=] near the end of the episode himself'', despite the fact that his goal is to rid the world of [=E.V.Os=], he says he was doing it to prove Rex wasn't as good a protector everyone thinks he is, and did that just to kill Rex, which makes it ''worse''.
* ICallItVera: Hunter Kain's E.V.O-killing {{BFG}} is called "[[ShoutOut Sweet Caroline]]".
* IDidWhatIHadToDo: [[spoiler:Cesar and the other scientists who were working on the nanite project. When the Consortium tried to take the Meta-Nanites, they caused the Nanite event(yes THAT Nanite Event) in order to scatter them across the globe lest the Consortium use them to become Gods. Still what came after MassSuperEmpoweringEvent / BodyHorror abound wasn't his goal but still....]]
* ImDyingPleaseTakeMyMacGuffin: [[spoiler: Dr. Rylander injects Rex with a new nanite. Turns out it can control other Nanites... [[CoconutSuperpowers And bring Rex back from the dead]].]]
* IdentityAmnesia: [[spoiler:Rex. His personality has changed in the past between his amnesiac blackouts, such as his self-serving traitorous nature when he was in Hong Kong, as opposed to his current, more heroic personality. It is currently unknown whether Rex's current personality matches with his personality before the amnesia set in.]]
* IdiosyncraticWipes: Usually done such that if a character moves out of frame, they take the image with them, revealing the next scene behind it.
** The giant cog flash and nanite StockFootage are also part of the scene changing.
* IfItSwimsItFlies: Van Kleiss controls an E.V.O whale-blimp.
* IJustWantToBeNormal: Rex, being a teenager forced into fighting monsters for a living, naturally has some shades of this. One of the villains, Circe, also feels this way. Strangely, Circe looks completely human, yet feels her powers (which do make her look like a freak when she uses them... voluntarily) prevent her from doing this even though she could logically fit in anywhere. Instead she works for the BigBad. She does mention that she's a WeirdnessMagnet, however, though it's not clear if it's an active or passive facet of her powers.
** Not explained is why Circe didn't [[FridgeLogic just get Rex to cure her]]. Maybe she's one of the E.V.Os that he can't cure, but it's not even been ''tried''. And she must know he can by know, even if she didn't at the start.
* [[ImTakingHerHomeWithMe I'm Taking Him Home With Me]]: Breach does this with Rex in the episode named after her. It does not end well.
* ImYourBiggestFan: Sebastian claims to be this to the Trendbenders in "Rock My World". He not only considers himself their biggest fan, but their only genuine fan, as he liked their original stuff, which no on else has ever heard. He ends kidnapping them in an attempt to force them to go back to their roots.
* {{Infodump}}: A large one comes when [[spoiler: Rex meets his brother]].
* InsistentTerminology: Bobo's "simian undergarment".
* InstantExpert: Briefly averted in End Game Part 1, when [[spoiler:the consortium are all fighting Rex. He mentions explicitly that he has had much more practice with his Nanites and kicks some ass. Of course, then they fuse...]]
* IntrepidReporter: Diane Farrah, the (for a while nameless) reporter who appeared everywhere.
* IResembleThatRemark: Stated word-for-word by Bobo in "Gravity" in reference to ZAG-RS destroying all E.V.Os.
* IronicEcho: In Rampage, "Here's where you must be thinking: Did I think this plan through?", first said by Rex to Van Kleiss, then Van Kleiss to Rex after [=EVOing=] Noah.
* ItTastesLikeFeet: Said almost word for word by Bobo in "Badlands" when he drinks an expired can of soda:
-->"This tastes like feet! And not the clean kind!"
* JerkWithAHeartOfGold: Agent Six. He may stick to orders to a fault, but even he has his limits. [[spoiler:Despite orders to "bleach" NYC, he took the bomb's activation key to prevent it from detonating, giving Rex a chance.]]
* JesusTaboo: Averted in the second episode where the current E.V.O Rex was fighting was a priest, a rare example of a modern cartoon averting the trope.
* TheJinx: Annie, who has the nickname "The Blonde Widow". Her every action precipitates DisasterDominoes. This is played down in the second appearance.
-->'''Noah''': ''Every guy who's ever gone out with her has ended up in the hospital, or worse!''
* JokerImmunity: Van Kleiss. The show actually kills him off for a fair bit when Rylander throws him into a nanite reactor, but he eventually comes back. [[spoiler:Thankfully, Rex was able to find a way to [[BroughtDownToNormal bring him down to normal]].]]
* JustBeforeTheEnd: Five years after its outbreak, the E.V.O plague has devastated the world, reshaped its ecosystem, and even changed its political structure. Without a cure, it'll eventually wipe out the human race.
[[/folder]]

[[folder:K-O]]
* KentBrockmanNews: In "Exposed", a news team doing a story on Providence gets taken on a tour of the entire facility, and witnesses an EVO outbreak, getting every minute of their time there on film. The end result? A cheesy tabloid piece on Agent Six.
* KarmaHoudini: [[spoiler: Black Knight and the remaining Consortium in the GrandFinale.]]
** [[spoiler: Played with for Ceasar. He and his parents unleashed the Nanites, causing millions of deaths, and changing the world forever, but they did so under duress, and under the threat of The consortium or Van Kleiss obtaining the meta-nanites (Considering who they are, the world would be in worse shape). His parents die, but he continues to be mobile. Ceasar does several amoral things, and he does seem to lack empathy, very notable when he tried to mind control Rex. Rex calmly punches him in the face in the finale.]] His punishment vs. the things he did vs. the reasons in which he did them, make him an unusually case.
* KickChick: Cricket, who naturally got proportional leg-strength with her namesake mutation.
* KillEmAll: In "The Architect", [[spoiler:the AI decides the best way to protect itself from the Nanites to to make them all self-destruct. Naturally, the human race goes with them]].
** Hunter Kain also takes this view against E.V.Os, denying all logic to the contrary.
* KillerRabbit: Nanites + Bunny = One very dangerous rabbit.
** It's intro scene in "Operation: Wingman" in particular may have also been a subtle ShoutOut to the ''[[Film/MontyPythonAndTheHolyGrail original]]'' KillerRabbit scene, considering the Providence soldier Rex talks to has a Scottish accent.
* KnightOfCerebus: Black Knight. It's always been a pretty dark show, but it got significantly darker when she took over Providence. Even the breather episodes are more comedy painted over the conflict than straight-up funny.
* KnightTemplar:
** White Knight is willing to destroy all of New York City, along with everyone and everything in it, just to stop one E.V.O. Admittedly, it did have the power to [[ZombieApocalypse zombify regular people by touching them]].
** Black Knight is ''much worse''.
* LargeHam: Gatlocke is this in spades. Loves to hear himself talk, check. Has overblown mood swings, check. Overall flair for the dramatic, check and check.
* LaserGuidedAmnesia: Rex has no memories of his life a few months before joining Providence. Van Kleiss explains that the two of them were right at the base of the explosion, so that probably has something to do with it.
** It's confirmed in "Rabble" that Rex has some kind of condition [[spoiler:that gives him amnesia several times throughout his life, and it's not a matter of if, but ''when'' it will happen again.]]
** In "Six minus Six", Six loses all of his memories of the last six years; forgetting all of his friends, and turning into a morally dubious, casanova, jerkass.
* LastSecondChance: Rex offers one to Garan-Set, who unfortunately doesn't take it.
* LessEmbarrassingTerm: Bobo is always peeved whenever anyone refers to his "simian undergarment" as a diaper.
* LetsYouAndHimFight: How the ''Ben 10'' Crossover "Heroes United" starts
* LightningBruiser: The giant E.V.O bunny. Strong, able to take some solid hits and fast enough to run away to come back and hassle Rex latter.
* LikesOlderWomen: 15-year-old Rex really likes hitting on Doc Holiday who's in her late 20s, even after he falls for a girl his own age, though it switches to semi-teasing after that.
* LikeParentLikeSpouse: Rex is attracted to Doc Holiday, and according to Van Kleiss, Violetta Salazar was a willful, headstrong but brilliant scientist - sound familiar? [[spoiler:It doesn't hurt that GreyDeLisle voices both Holiday and Rex's mom AKA ZAG-RS.]]
* LimitedWardrobe: Most of the characters. Lampshaded right off the bat when Holiday asks Six if he's [[TheMenInBlack ever going to buy another suit]]. Rex actually manages to do this trope through a flashback, wearing the exact same clothes when he was five years younger. Even Six had a different outfit back then.
** Actually if you go back and re-watch that episode you will see that Rex's outfit was different: black shirt not white, blue jeans not leather(?), no goggles and no gloves.
** In the episode "Operation: Wingman" Rex borrows one of Six's suits for yet another formal occasion (in this instance, prom night). When Six returns to his flat and discovers his closet is ajar, the viewer catches a glimpse within—where there are twelve ''identical'' suits. Rex is wearing one and Six was wearing one all day, so that adds up to two green suits for every day of the week!
*** Rex even lampshades it "There isn't much choice when you're shopping in Six's closet."
* LivingBattery: There's a whole country that gets its electricity from a single EVO.
* LongLostSibling: [[spoiler: Rex]] learns from Rylander that [[spoiler: he]] has a brother, and then meets him later.
* LoonyFan: Sebastian in "Rock My World".
* [[LovecraftianSuperpower Lovecraftian Super]][[SuperpowerLottery power Lottery]]: The nature of many E.V.Os' powersets, from Van Kleiss to Meechum to Circe. Compare to BlessedWithSuck above, it's random what [[BodyHorror you'll look like]] or gain any powers from it. [[SuperpowerRussianRoulette (Hell, you'd be lucky to maintain sapience.)]]
* LukeIAmYourFather: An interesting example in "Written in Sand". It turns out that ZAG-RS was originally been a decontamination system designed by César, Rex's brother, in order to eliminate stray Nanites during the project. The trope really comes in, whoever, when César reveals that since he wanted the program to give the feeling of protection and safety, [[spoiler:he modeled ZAG-RS' voice after that of their mother.]]
* ManChild: Instead of being dark and truly evil, like other villains, Gatlocke seems to act cheery and a little childish.
* MagicPants: Justified for Rex, who can control his Nanites. Averted for RuleOfFunny in the first episode. The first person Rex cures of E.V.O infection had grown to a skyscraper-sized monster. He's naked upon being cured, and is quickly covered by a blanket. The old man then hugs Rex in gratitude, just in time for the blanket to fall off. HilarityEnsues. (It's generally accepted as {{fanon}} that he was showering at the time.) Beyond that, most cured E.V.Os revert fully-clothed regardless of the mutation, or at the very least still have pants.
* MakeMeWannaShout: Circe's power.
* MaleGaze: Doc Holiday's shot in the intro starts with a zoom-away from her chest.
* MamaBear: Holiday shows signs of this in "Breach".
* MassSuperEmpoweringEvent: The nanite explosion five years prior to the start of the series infected every living thing on Earth with Nanites. While they are dormant most of the time, they will occasionally activate. Unfortunately, most things (people or otherwise) are mutated into super-powered monsters as a result. Only the lucky ones get any control over their powers (or indeed, any semblance of intelligence). Worst part is that there's no telling ''when'' these powers will emerge, so technically all life on Earth are time bombs waiting to go off.
* MauveShirt: Pretty much all of the [[RedShirt Providence soldiers]] who are seen without helmets. Except [[VillainOfTheWeek Weaver]].
* MeaningfulName: Rex and Cesar's names both mean "king" - makes you wonder what their parents expected of them. Gabriel Rylander and Rafael Salazar, the two leading scientists on the nanite project, share their names with two archangels. Circe was an evil witch in Greek mythology whose voice could seduce and had the power to turn men into animals with her potions.
** Providence itself. Providence, Rhode Island was first set up as one of the first refuges for Puritan dissentors; in other words, a home for outcasts, such as Rex.
*** The name takes on a darker meaning in season 3 when it's true goal is revealed: [[spoiler:to deliver the power of gods (in the form of the Meta-nanites) to its financial backers the Consortium.]]
* MechaMooks: Rylander uses these to defend his base in his first appearance. [[spoiler:Black Knight's elite Black Pawns are revealed to be this in "End Game, Part 1".]]
* TheMenInBlack: Agent Six, in all but suit color. But even then, it's still a darker shade of green.
* MickeyMousing: The beginning of "Robo Bobo", when Rex is fighting the second KillerRabbit, is full of cartoonish sound effects.
* MiniDressOfPower
* MotorcycleDominoes: Rex kicks over a row of motor scooters in "Breach".
* MuggleBestFriend: Noah, [[spoiler:although he was hired to pretend to be Rex's friend and spy on him, but became so in truth]].
* MultitaskedConversation: In "A Brief History of Time", Cesar notices that someone cloaked is following him and the providence agents, he loudly proclaims what they're going to do for the followers benefit
* MundaneUtility: The Evos that Providence collars are put to use for such tasks as harvesting wheat and helping little old ladies cross the street.
* MyFriendsAndZoidberg: In "Enemies Mine", Rex gets called back to base and tries to stay saying, "My four worst enemies are still on the loose. Well, my three worst enemies and Valve." He spends practically the whole episode saying things to similar effect.
* MysteriousPast: Rex. In addition to everything else, [[spoiler:now it turns out Rex once ran a RagtagBunchOfMisfits in Hong Kong.]]
* {{Nanomachines}}: The source of all the powers/mutations in this show.
* NeverFoundTheBody: [[spoiler:Rylander and Van Kleiss apparently die when Rylander pushes them both into a nanite reactor. They just vanish, much like Breach just an episode earlier.]]
** [[spoiler:Van Kleiss and Breach both make a trimphant return in "What Lies Beneath". Kleiss was actually dead, though, so Rylander is no doubt gone.]]
** [[spoiler: Not gone, just spread a little thin]]
** [[spoiler: Breach and Van Kleiss in "Lions and Lambs". The latter of whom eventually has his own episode of how he returns to the present.]]
* NeverSayDie: Averted. They've said "kill" repeatedly, and actually tried to do just that just as much.
* NeverTrustATrailer: The trailer for "Frostbite" implied that Rex would be fighting some monster in a cold climate while at danger of nanite overload. [[spoiler:This is ''technically'' true, but almost all the voice-clips used are from TheTeaser, which ''also'' involved Rex being in danger of overload.]]
* NewEraSpeech: [[spoiler: Given by Black Knight during the second part of the GrandFinale. Oddly enough, it appears to have been ''pre-recorded'' as the speech starts with Black Knight, in her pre-metananite human form, talking to the camera while seated in the Consortium boardroom.]]
* NewPowersAsThePlotDemands: After he's injected with the Omega nanite, Rex gradually gets new weapons and sometimes demonstrates new features such as BackFromTheDead.
* NiceHat: Bobo Haha wears a fez.
* NiceJobBreakingItHero: "Lions and Lambs". Rex has just gained [[spoiler: Breach]]'s trust... then White Knight shows up, deciding to take her in by force. And everything falls apart.
* NoLongerWithUs: At the end of the "Ben 10/Generator Rex: Heroes United", Rex asks where the injured Six is, prompting this response:
-->'''Bobo:''' He's gone...
-->''(Horrified reaction from Rex)''
-->'''Bobo:''' ...to the little ninja's room.
* NoodleIncident: Lansky in "Moonlighting" has a RunningGag of "I can't go to (X). Long story."
* NotQuiteDead: Occurs [[spoiler:with Rex himself in "The Swarm". Remember that huge nano-chunk Rylander injected him with? It can keep him from dying over an extended period.]]
* NotSoDifferent: Gatlocke tries this on Rex in "Badlands", while they're having a swordfight atop an out of control truck heading toward a cliff. Just before the truck reaches the edge, Rex retorts that there is a major difference between them: Gatlocke can't fly.
** Garan-Set tries this on Rex as well [[spoiler:right before his Nanites break down and he crumbles to dust.]] He warns Rex that the world will never accept people like them.
* NotWhatItLooksLike: In "Robo Bobo", Holiday walks into Rex's room to find Rex kneeling on the floor with his face seemingly pressed up against Bobo's butt. Her "I'll come back later" is priceless.
* NowOrNeverKiss: Between Rex and Circe [[spoiler:just as they are close to the edge of Van Kleiss' castle while the Black Pawns have them trapped; Circe returns Rex's feelings for her, and the two share a passionate kiss before Rex falls and Circe is captured by Providence]].
* NuclearWeaponsTaboo: The "Bleach Protocol" isn't actually a nuke, but a "forced plasma cascade". When Six mentions this to Rex in "The Swarm", Rex points out that "NukeEm" still makes for a much better CatchPhrase.
* NukeEm: A proposed solution to the zombie-making E.V.O, but never implemented. Tried on the bugs in "The Swarm", which just made them multiply.
* ObliviousGuiltSlinging: In "Lockdown", when Rex gives Noah a tour of Providence's base.
* ObliviousToLove[=/=]SelectiveObliviousness: Cricket's crush on Rex.
* OfficialCouple: [[spoiler:Rex and Circe, basically from her introduction, but more blatantly in "Assault on Abysus" and then post-series]]
** [[spoiler:Six and Holiday at the end of "A Family Holiday" until Six loses his memories in "Six Minus Six"]]
** [[spoiler: "Mind Games" brings the relationship back into full view, forcing Holiday's feelings for Six to resurface in the worst way]]
* OfficialCoupleOrdealSyndrome: [[spoiler:Six and Holiday. They get together finally after two seasons of build-up, and then he immediately loses his memories and forgets everything that happened. Then it's brought up again in "Riddle of the Sphinx", "Heroes United" (slightly), and especially "Mind Games"]]
* OneWingedAngel: During the flashback episode "Promises, Promises", Rex somehow built himself into a giant robot with all his E.V.O powers combined. It gave the military a good fight until Six stabbed it in the shoulder, at which point it exploded just after grabbing Six and ejecting its hand, which contained the amnesiac Rex.
* OurVampiresAreDifferent: Just about everything about Van Kleiss screams "vampire" from his appearance and clothing to his creepy castle in the middle of a dark forest. And of course there's his [[ImAHumanitarian diet]] (albeit draining [[AppliedPhlebotinum Nanites]] instead of blood). He differs in his toleranceof sunlight and [[GeniusLoci control over the lands surrounding his home]], but needs to be around at least some of his native soil at all times, as in some vampire myths.
** With season two and his new power to [[spoiler: force Nanites into turning other people into E.V.Os, and leaving behind a visible mark after they change]], any possibility of him not being a reference to a vampire is lost.
* OutOfOrder: The crossover episode has several events which place it ahead of "Black and White", at least. It aired near the start of the season.
[[/folder]]

[[folder:P-T]]
* PantyShot: Averted with Cricket, who was wearing black shorts under her skirt.
* PapaWolf: Six in "What Lies Beneath". [[spoiler: He protected Rex from Biowulf with "Don't even breathe" ...]]
* PeoplePuppets: Peter Meechum, as an E.V.O, can activate the Nanites in anyone he touches, granting him control of their muscles, [[AndIMustScream but not their minds]]. The one guy Providence captured who had been affected, though, was a remarkably good sport about it. The rest just keep quiet.
** Quarry gets access to tech that can allow E.V.O.'s to be controlled remotely through their collars. [[spoiler:Providence is mass-producing it.]]
* PersonaNonGrata: Lansky can't go to New Jersey. ItsALongStory.
* PersonOfMassDestruction: From what is seen, it might be deconstructed with Rex. Despite being the only thing capable of curing E.V.Os and pretty powerful, the higher ups are more concerned with him doing his job rather than going rogue and Rex [[IJustWantToBeNormal just wants have a bit of normality in his life]] instead of being caged up like some animal.
* PhlebotinumBreakdown: Nanites from the time of ancient Egypt have been active, albeit in a sort of sleep mode, for so long that they shut off after just an hour or so of extended use.
* PhlebotinumMuncher: Van Kleiss [[OurVampiresAreDifferent drains nanites]] out of other E.V.Os to sustain himself. It doesn't end well for the victims.
* PhlebotinumOverload: A consistent problem for Rex, who absorbs nanites from E.V.Os. He does have space limits, so he has to be regularly evacuated to remote medical bases to have his surplus nanites offloaded. It's a major plot point in "Frostbite", combining terrors with borderline CyberneticsWillEatYourSoul.
* PinPullingTeeth: Hunter Kain does this in "Night Falls".
* PiranhaProblem: In episode 9, of the E.V.O-mutated, ExtremeOmnivore, FlyingSeafoodSpecial variety.
** Enters horrifying territory when a Providence soldier falls in the water. RedShirt, [[FacelessGoons Faceless Goon]], or not, that's just plain nightmare-inducing...
* PocketDimension: As if Breach wasn't scary enough. She treats this one as her personal dollhouse, having taken an entire town two years prior to the current time-frame.
* PowerNullifier: See BroughtDownToNormal, above.
** More conventionally, a man in "Deadzone" constantly projects a field which renders nanites inactive or dormant (Rex describes the feeling as "fuzzy"). This has the effect of making Rex's machines instantly fall apart if he tries to build them under its influence.
* PowersAsPrograms: Rex's constructs are literally a program giving the nanites instructions on what to build.
* PowerTrio: This is what Rex's old E.V.O. gang back in Hong Kong was once was when he left and before Circe joined them.
* PrisonRiot: Valve, Gatlocke, Hunter Cain and No-Face use a prison riot as cover for their break-out in "Enemies Mine".
* PsychoactivePowers: Rex's control over his Nanites seems to be linked to his confidence. When he gets nervous, upset, or angry, his {{Shapeshifter Weapon}}s [[PsychosomaticSuperpowerOutage fall apart.]]
* PyrrhicVictory: In [[spoiler:"Assault on Abyssus", Rex was able to acquire a meta-nanite. However, Circe and the Pack (who had teamed up with him to stop Providence) have been captured.]]
** There's also the inevitable fact that Black Knight will attack their base to get them anyway, at least once the threat of White Knight's blackmail is no longer relevant.
* QuirkyMinibossSquad: Apparently the villain is more GenreSavvy than the heroes in this show, as he forgoes an army in favor of such a group [[ConservationOfNinjutsu (and it works)]].
* QuoteMine: The news report in "Exposure" does this to Six to make him look even more cool/desirable than he already is.
* RaceLift: In [[http://www.comicvine.com/rex/29-70588/all-images/108-369083/rex1/105-1198378/ the original comic]], Rex is blond and blue-eyed, while in the show, he's Latino. Some conceptual art shows that they may at one point planned on using the original design, albeit aged up. There's also some with Rex looking like a humanoid version of the Megawhatt from ''WesternAnimation/{{Ben 10}}''.
* RealSongThemeTune: "Revolution" by the indie-punk band Orange is the show's theme, albeit in severely cut-down form. And yes, it is found on their latest album and can be downloaded on iTunes.
* RedOniBlueOni: Rex has two Blues in the form of Six and Noah. Possibly a third in Holiday, as well.
* RedShirtArmy: Providence's foot soldiers fill this role. While escaping Van Kliess' stronghold, Rex comments that he expected Providence to send an army to rescue him rather than just Six. [[spoiler:At that moment they run past the remains of one of Providence's drop ships...]]
* RealPlaceBackground: Greenville, Ohio and New York City get not only major backdrops to the plot but if you ever visit you might recognize a little too much from the show. Also several other locations which get named look like their RealLife counterparts.
* ReedRichardsIsUseless: The Architect uses nanites to create machines that help an entire village run smoothly, and could as well have divulged these inventions to the world. He doesn't because, as Rex is told, he is a "perfectionist". [[spoiler:It turns out there are entirely more sinister reasons.]]
* ResetButton: Notably averted two times when it was expected, with [[spoiler: Six's LaserGuidedAmnesia]] and [[spoiler: the TimeSkip]].
* TheReveal: Noah reveals to Rex in the fourth episode [[spoiler:that he (Noah) has been working for White Knight before he and Rex even met.]]
* RoadsideWave: Rex and Noah get splashed by the DrillSergeantNasty's jeep during the crosscountry run in "Basic".
* RoboticReveal: [[spoiler:The Black Pawns are robots.]]
* RuleOfCool
* RuleOfFunny: "Operation: Wingman" ran almost entirely on this.
* RunningGag: Trains. So many trains. Pretty much every time Rex gets ''near'' a subway or other train line he's pretty much guaranteed to have a near miss with a train. Even Breach seems to be aware of this: in "Hard Target" she sends him through one of her portals and straight onto a train line. Of course, there's a train heading straight for him.
** Also, when Providence {{Red Shirt}}s are having a bad day, the WilhelmScream is seldom far away.
* ScaryScorpions: Six and Bobo encounter a nest of giant scorpions in "Breach".
* ScaryShinyGlasses: Black Knight's EliteMooks have shiny visors.
* SchizoTech: Ancient Egyptian nanite technology. [[spoiler:Makes sense with the reveal that Van Kleiss was apparently sent there by Breach.]]
* ScrewTheRulesImDoingWhatsRight: Rex, Six, and Holiday do this. A ''lot''.
* SelectiveMagnetism: Agent Six's swords can be combined to create a single sword capable of lifting ''cars''.
* SelfDuplication: Sebastian in "Rock My World".
* SeriousBusiness: '''Table Tennis'''.
-->'''Rex''': I don't get this much respect when I save the ''world''!
* ShapeshifterBaggage: E.V.Os can get mass from basically nowhere, and the show's one attempt at a justification was quickly ignored in later episodes.
* ShapeshifterWeapon: Rex himself.
** {{BFS}}: One of the weapons his arm turns into, the "Big Fat Sword." It can also turn into a [[EverythingsBetterWithSpinning giant]] [[ChainsawGood buzzsaw]].
** {{BFG}}: The "Slam Cannon". A ridiculously huge gun that creates ammo by trash-compacting debris from Rex's surroundings. Essentially, it's ''VideoGame/{{Fallout 3}}'''s Rock-It launcher in a somewhat more realistic and practical form. It's interesting to note the tactical limitations of having a gun that requires external ammo- for example, Rex has been in a number of fights set on moving vehicles, where he wouldn't be able to grab anything to put into the Slam Cannon, and thus doesn't really have any ranged attacks.
** CoolBike[=/=]FlyingCar: "The Rex Ride", a hoverbike that grows out of his legs/waist ([[DoesThisRemindYouOfAnything see the page image]]), and also comes with a battering ram.
** GoombaStomp: The "Punk Busters" allow a rare non-videogame example, turning Rex's feet into a pair of giant spiked boots that can be used to stomp, kick, or otherwise teach enemies a lesson in pain. It also grants him InASingleBound abilities, crossing miles in just a few jumps.
** HelicopterPack: The "Boogie Pack" is basically a pair of turbines that grow from his back. Avoids the problem with most jetpacks as it's not using chemical propulsion and the turbines are well away from his body. It comes with giant bola that can be launched from the turbines.
** PowerFist: The "Smack Hands". Two ridiculously huge fists. If that wasn't enough, they can [[EverythingsBetterWithSpinning spin]] for more damage.
** WhipItGood: Rex's first new power, which also has ShockAndAwe abilities.
** EpicFlail: makes debut in "Rampage". Rex got one for [[DualWielding each hand]], and when slammed together they create a powerful [[KamehameHadoken energy blast]].
** AnAxeToGrind: Makes its debut in "Divided by Six." Like the aforementioned EpicFlail, he [[DualWielding uses two at once]].
** DeflectorShield: Debuts in "Hard Target", and they are projected by a pair of large gauntlets. [[spoiler: In the same episode, it also serves as an AttackReflector against Quarry's EnergyWeapon.]]
** HoverBoard[=/=]SkySurfing: First appearing in "Lions and Lambs", it's a board with PureEnergy turbines on each end, which can be used as weapons.
* SheIsNotMyGirlfriend: Circe to Rex. Not that it stops Six and Holiday from teasing him.
** Rex uses this exact line in "What Lies Beneath".
* SheCleansUpNicely: Dr. Holiday for a UN conference in "Leader of the Pack".
* ShipperOnDeck: After ''A Family Holiday'', Rex occasionally hints that Six and Holiday should get together.
* ShipTease: Between Rex and Circe. And a bit between Six and Holiday. [[spoiler:The latter reaches boiling point in 'Family Holiday', resulting in the two sharing an AlmostKiss during the mission and Six asking Holiday out once they're back at base. Quoth Holiday: [[LampshadeHanging "It's about time."]]]]
* ShirtlessScene: Rex in "Beyond the Sea".
* ShoutOut:
** [[Film/{{Tombstone}} Doc Holiday]]? ''Really''?
** The giant explosion in the beginning is an obvious ''Manga/{{Akira}}'' reference, and there's several more down the line.
** "Breach" is an obvious ShoutOut to ''SilentHill''. A foggy town filled with monsters, a creepy school, and a possible alternate dimension/reality involved. Check, check, and check. It wouldn't be surprising if "Man of Action" came out and said they're fans of the series.
*** Breach being shot with a small cannon at Doc Holidy's order is similar to a scene in ''Manga/ElfenLied''.
*** Also, the whole concept of magically making a town into one's own personal playpen is lifted from ''Series/TheTwilightZone''. There was an episode where a young boy used his psyhcic powers to magically remove his town from the rest of the world because he was mentally unhinged.
*** One of the alternate worlds that she takes Rex to in "Lions and Lambs" is a reflective surface surrounded by stars, similar to the setting of the dance scene in the ''RevolutionaryGirlUtena'' movie.
** The standard Providence Rifle looks like a white [[TabletopGame/{{Warhammer 40000}} Bolter]].
** Anyone else think those rat/dog things in "The Architect" looked like the mutated rats from ''VideoGame/ParasiteEve''?
** "Operation: Wingman": In the first part, it shows a Providence truck and crew wrecked and broken up, all done by a bunny who looks innocent, but isn't. [[Film/MontyPythonAndTheHolyGrail The soldier that tells Rex not to underestimate the bunny had a Scottish accent, for crying out loud!]]
** Hunter Kain and his goonsquad, from their ideals to their weaponry, seem to be a shout out of the Quarrymen from ''WesternAnimation/{{Gargoyles}}''.
*** Hunter Kain himself seems like a combo of ThePunisher (in terms of ideals, and it's directly stated that he lost his wife to E.V.Os) and the Juggernaut (in terms of last name and overall design).
*** And his gun is called "Sweet Caroline", an obvious Neal Daimond reference.
** The skyscraper-sized biomechanical monster ([[spoiler:which was actually ''Rex'']]) in "Promises, Promises" looks suspiciously [[Anime/NeonGenesisEvangelion EVA]]-like.
** The baddie ''Gatlocke'' bears a resemblance to ''Sword Hunter Cho'' from ''Manga/RurouniKenshin'', while his henchmen resemble the Mooks from ''CaptainHarlock''.
*** Also, one of his attacks (two blades sprouting from his metallic hand) looks almost exactly like one of the GurrenLagann's attacks.
** ''Series/KamenRiderDouble'' fans might think the way Van Kleiss controls and uses his glove in the first SeasonFinale looks a lot like the [=LunaJoker=] combination.
** In "Rampage", Van Kleiss uses his glove to imitate a [[Franchise/ANightmareOnElmStreet famous character who also sported claws]].
** "Waste Land" gives us a musical shout out, in the form of action music that's a blatant homage to the ''PiratesOfTheCaribbean'' theme.
** The Bobo robot loked very [[{{Terminator}} familiar...]]
*** Bobo's origin? He entertained children, and his owner was "a dude in a purple hat." [[IncrediblyLamePun Very]] [[CuriousGeorge curious]]...
*** Robo-Bobo's last words are from Film/Bladerunner
** ZAG-RS = [[Series/DoctorWho Zagreus]]?
** Five, with her pink hair and [[ImprobableWeaponUser guitar]], seems to be a shout out to [[Anime/{{FLCL}} Haruhara Haruko]]. All that's missing is the Vespa.
** Speaking of Five and the other mercenaries, anyone else catch a ''NoMoreHeroes'' vibe from Six's old crew. They're all ranked by how deadly they are, they look nothing like your traditional assassin/mercenary, and seem to have near superhuman powers without technically being superhuman.
** Episode 33, "Written in Sand" has Rex using his [[WhipItGood whip arm]] to trip ZAG-RS' massive colossus form, only for the whip to snap. Rex remarks how it "''[[StarWars Worked in the movie!]]''"
** Towards the beginning of "Heroes United," Rex tries writing a theme song for himself. The brief snippet we hear uses the exact same tune as the original ''WesternAnimation/{{Ben 10}}'' theme.
** The [[spoiler: Consortium's Meta-nanite powered]] faceless, multicolored, shiny armors are very similar to Marvel Comics' [[CosmicEntity Celestials]].
* TheSimpleLifeIsSimple: Both averted and played straight in "Hermanos". Rex thinks running a ranch will be simple and soon discovers that it isn't. However, Claire is able to learn an awful lot about farming just by watching videos on the internet.
* SlapYourselfAwake: In "Plague", Holiday uses a series of low-level elecrical shocks directly to her brain to keep herself awake after the eponymous plague causes everyone else in the world to fall asleep.
* SoundtrackDissonance: Considering the dark tone of the series the somewhat random surf music and cheery opening sometimes feel very out of place.
** The impact of some darker episodes, like "Breach" and "The Hunter", is somewhat lessened by the stock cartoon sound effects that run in the background during fights.
* SpitTake: Rex gets one in "Outpost" upon being told that the drink he is imbibing is made from rice that has passed through the digestive tract of a monkey.
* StandardEvilOrganizationSquad: The Pack straddle the line between this and a serious QuirkyMinibossSquad.
* StatusQuoIsGod: Astonishingly subverted in "Six Minus Six". [[spoiler: Agent Six [[LaserGuidedAmnesia loses all but his pre-Event memories]], but doesn't get them back by the end of the episode.]]
** Averted in "Back in Black" too-- [[spoiler: Providence is not restored to normal by the end of the episode. Rex is not returned to six months earlier. Our core cast of characters have created/joined a secret, smaller organization rivalling Providence.]] Generally, there is a lot less of this as the episodes go on.
** Eventually, [[spoiler: the status quo is partially restored by the time of Endgame, with White Knight and his team getting Providence back, Van Kleiss escaping the cure event and being a threat again, and Rex fighting for Providence again (see BookEnds above). However, the major difference is that all the EVOs in the world are cured (except that there are still nanites in the atmosphere) and Providence now deals with other threats, such as the giant robot Rex fights in the end.]]
* SteppingStonesInTheSky: Six in the pilot; Rex in "Breach".
* StockSoundEffects: Rex gets these quite often, but they're especially noticeable in "Breach" before things get ''really'' serious.
* StormingTheCastle: Rex in "Rabble".
* StrangeSecretEntrance: There's a village that is hidden behind some sort of invisibility field. You can only get into it if you know where to walk into/through it.
* StrappedToAnOperatingTable: Happens to Rex for the operation to fix his PhlebotinumOverload.
** Also happens to Rex [[spoiler:when Providence is planning to ''kill him.'']]
* StrongAsTheyNeedToBe: Rex's strength tends to vary wildly, even within single episodes. Compare "The Day Everything Changed" to "Badlands." In the latter, Rex fights a largely ordinary human in sword to sword combat, and defeats him after quite a bit of struggle, right after tossing aside one of Gatlocke's trucks. No matter how good Gatlocke's own enhancements, he's clearly not that strong. In the former, Rex jumps out of an airplane to take on a [[AttackOfTheFiftyFootWhatever giant monster E.V.O]]... Yeah...
* SunglassesAtNight: Six seems to wear his shades 24/7.
** In the episode "Divide by Six", we finally see his eyes for the first time.
* SuperHumanTrafficking: Thanks to [[spoiler: the new mind controlling collars]] Providence is now not only able to capture [=EVO=]s, but also use them for various tasks, like collecting crops. They don’t distinguish between sentient and non-sentient ones. Official propaganda says that it’s a method to create “a better future for all [=EVOs=]" and help integrate them into the society. [[spoiler: Quarry]] tried to use the same method to create his own personal army.
* SuperOCD: Breach doesn't like when you mess up her dollhouse-town.
* SuperPrototype: [[spoiler: Rex compared to the rest of the E.V.Os]], as revealed in "Dark Passage". Justified, however, in that the batch that caused the MassSuperEmpoweringEvent weren't fully finished or programmed yet, which causes their deficiencies.
* SuperpowerRussianRoulette: Becoming an EVO usually means turning into a mindless monster. If you belong to this small group that kept their minds, you still remain one mass of a BodyHorror. Even [=EVOs=] looking relatively normal experience unpleasant side effects. Van Kleiss has HorrorHunger for nanites, Circe became a WeirdnessMagnet, and Rex got a chronic condition that periodically gives him LaserGuidedAmnesia, along with a SuperpoweredEvilSide. The real winners are [=EVOs=] like Bobo--that is, animals who gained human-level intelligence. This group seems to be even smaller.
* SurrealHorror: Breach's pocket dimension.
* TheTeaser
* TechnologyPorn: Rex thinking up the blueprint for the whip.
* {{Technopath}}: In addition to his power over Nanites (both his own and others), Rex can control machines simply by touching them.
** As of "Frostbite," this seems to be reaching new boundaries. [[spoiler:With enough Nanites in his body, Rex seems to be able to channel some sort of speech pattern from them.]]
** And as of "Payback", he disarms [[SomebodySetUpUsTheBomb bombs planted all over]] [[spoiler: Providence's main base]] by shutting down everything in the building at once.
*** In the same episode, Van Kleiss has a Technopath of his own, in the form of a strange, crustacian E.V.O,
* TeleportersAndTransporters: Breach can fire portals from her giant hands, using them to wisk people off to god knows where, go wherever she wants, or surround people with portals and attack from every angle. She's essentially an {{Expy}} of Marvel's portal-creating character Spot in all but appearance, which is closer to that of Spiral.
** Bit of FridgeHorror here is that Breach can send them anywhere. Middle of the desert, over the ocean or into a volcano (probably, but this is on Cartoon Network), straight to Van Kleiss; ANYWHERE. And don't worry about pesky things like "heat" or "air-pressure". In her titular episode, she sends something ''straight to the bottom of the Atlantic'' without any noticeable effect on the "in" portal. Not to mention the fact that she 'tore' the town of Greenville from the ground, implying she can move the parts of a target she desires. Now imagine if she tried this on a person....
*** It's later revealed that she took the ''entire city of Greenville, Ohio'' and teleported it to a pocket dimension, where she turned it into a ''SilentHill''-like "dollhouse."
* TeensAreShort: For some reason, Rex, Noah, Circe, and really every teen on the show, most of whom are within the 15-17 range, are noticeably shorter than most human adult characters. It's hard to compare them with the InnocentBystanders or other normal humans though, and Six does seem to be fairly tall.
* ThatManIsDead: Rex pulls this in "Rabble". [[spoiler: When [[VillainOfTheWeek Quarry]] offers to buy him off with the journal he kept before his most recent memory wipe, Rex decides that his past self [[AmnesiacDissonance was such a phenomenal]] {{Jerkass}} that he doesn't really care about that part of his past.]]
* ThemeMusicPowerup: When Rex discovers his new nanite power, the full version of the theme starts playing. And he promptly gives Van Kleiss a much needed ass kicking.
* ThereIsAnother: In "Dark Passage", [[spoiler: Rex finds out he has a brother.]]
* ThirdPersonPerson: Valve, a.k.a. 'the Biker'.
* TimeSkip: [[spoiler: Due to Breach's time device, Rex is warped six months into the future. Holiday and Six have left Providence, White Knight has been replaced by Black Knight, and [[ArsonMurderAndJaywalking Cesar has a goatee.]]]]
* TitleThemeDrop: '''All the time.'''
* TorturedMonster: Not stated outright, but heavily implied. Most people who've gone EVO seem to become insane, rampaging beasts, and generally seem ''very'' happy to be cured.
* ToxicPhlebotinum: [[spoiler:The Nanites were released with improper coding, hence the craptastic mutations. Rex, by comparison, is infected with an earlier, more stable version. This is why proper beta testing is ''important'', people!]]
* TrainingFromHell: "Basic" is all about Rex and Noah going through Providence boot camp, on a dare from the pilots from "The Forgotten". It's not as exagerated as such training usually is (aside from the ludicrous number of push-ups and sit-ups they're assigned), though they still had a fairly-standard DrillSergeantNasty.
** Except the whole "crash-land a real plane" part and fighting fifty-foot E.V.O monsters. That's kinda extreme.
* TwentyMinutesIntoTheFuture: As evidenced by the presence of {{nanomachines}} and a working (after a fashion) space elevator.
** Cesar's self-contained self-propelled lab capsule is ''lightspeed'' capable, which kicks things up a notch to extremely advanced space travel. But otherwise, the 'verse has a lot of standard contemporary elements.
* TrueCompanions: The episode "Hermanos" reveals that Rex feels this way towards Noah, Annie and Claire
* TwoGuysAndAGirl: This is what Rex's old E.V.O. gang back in Hong Kong was once was when he left and before Circe joined them.
[[/folder]]

[[folder:U-Z]]
* UndersideRide: In "Back in Black", Rex clings to the underside of a Providence transport to learn where Black Knight is having the captured [=EVOs=] shipped.
* UnfazedEveryman: Noah seems to fulfill all the requirements. [[spoiler: Except he's, you know, an agent of Providence hired to be Rex's friend and keep him in line without letting him know. He ends up blowing that last part thanks to a stress-induced FreudianSlip.]]
** Played Straight after Lockdown
* TheUnfavorite: Rex's main issue in "Breach" in dealing with the title-character's parallel dimension occupant.
* UnspokenPlanGuarantee: Used excessively in "Black and White", using plans within plans of varying levels of [[BuffySpeak unspokenness]].
* UnstoppableMailman: In "Double Vision", a massive E.V.O. plant is threatening to convert every living thing into copies of itself. While all this chaos is going on, a delivery girl is just driving around, apparently oblivious to the carnage surrounding her.
* UtopiaJustifiesTheMeans: New Providence has this mindset. To curb the Evo problem, all Evos are getting collared and brainwashed, even the intelligent ones who aren't a danger to anyone.
* VillainousBreakdown: Happens both literally and metaphorically at the end of "Breach".
* VillainTakesAnInterest: Rex and Van Kleiss.
* VillainWithGoodPublicity: New Providence. Their method for controlling Evos makes them very popular with the world, since said Evos can be put to work doing menial labor, but there's more going on than the public knows.
* ViralTransformation: What all E.V.Os undergo, often with bonus BodyHorror.
* TheVirus: The Nanites that mutate living beings/creatures into E.V.Os.
** Also, Meecham's effect on others. Which is, of course, a form of controlling the Nanites.
** A better example would be Patient Zero in "The Plague", the source of the coma-inducing mega-virus that affects every non-E.V.O on Earth.
** Hell, as of season 2, Van Kleiss!
* WalkingTechfix: One of the many uses Rex has for his Nanites. [[spoiler: Almost causes TheEndOfTheWorldAsWeKnowIt when he uses this talent to help his engineer friends build the transmitter in "The Architect".]]
* WeHaveReserves: It takes a special kind of {{Jerkass}} to tell this to the faces of his own men, and even says that they already knew.
* WeirdnessMagnet: Circe claims to be this, but it's not clear if it requires her to actually use her powers. It being passive is the likeliest reason, else she could just, y'know, not use her powers. It also has some interesting implications for her relationship with Rex, who is, you'll recall, an E.V.O himself.
* WellIntentionedExtremist: Van Kleiss, if he buys his own propaganda. Circe is probably a better example, since she definitely does.
* WhamLine: [[spoiler: Cesar: "The day everything changed, we never imagined what would happen when we released the nanites."]]
* WhamEpisode: Episode 6. Just, episode 6.
** And now episode 9.
** Episode 15 has a handful of crazy-intense moments.
** Episode 19. We learn a heck of a lot about everyone, particularly White Knight, and what most of them were intending to do with Rex.
** Episode 33 Cesar reveals he created ZAG-RS and her voice is based of his and Rex's mother.
** Episode 36. [[spoiler:There's a working cure for the Incurables, and Holiday's sister Beverly is its first successful test subject.]]
*** While that's impressive on its own, there's also [[spoiler: Rex finally getting over his attraction to Doc Holiday and Six actually asking Holiday out on a ''date'']]. Someplace very hot just froze over, people.
** Episode 40: Long story short, [[spoiler:Rex is sent ahead in time six months, where White Knight has tried (and failed) to take over Providence completely, and has been replaced by a woman named Black Knight. And Six, Holiday, and Bobo are all missing, with Cesar the only one having stayed.]]
** "Black and White". [[spoiler:Black Knight and the Consortium behind Providence want the meta-nanites, which essentially contain the base code for the universe. Whoever collects them all would have control over the building blocks of the universe. Cesar and his team also deliberately triggered the nanite event, because it was the only way to keep the meta-nanites from the Consortium.]]
** "Assault on Abyssus" [[spoiler: Circe comes to Rex when his Hong Kong pals are captured by Providence. The reason Van Kliess wanted Rex was to get to a meta-nanite under his castle, which no one else could do. Rex gets it before Providence, but Circe and the Pack, all of whom were helping him, are put under mind control.]]
* WhatHappenedToTheMouse:
** After the TimeSkip when Rex got sent six months into the future, the disappearance of the former Van Kleiss minion who pulled a HeelFaceTurn and joined Providence left a lot of fans asking this. A later episode reveals that he's still around, and that he was doing covert ops missions the whole time which is why we never saw him. Rex does {{Lampshade|Hanging}} it, though: when he sees the guy again he's forced to admit that he forgot he even existed.
** Also, whatever happened to Beverly Holiday, Dr. Holiday's sister? After she's cured Rex admits that Dr. Holiday is too old for him and becomes a ShipperOnDeck for Holiday and Six, and implies that he's interested in Beverly instead... but then we never see her again.
* WhatMeasureIsANonHuman: White Knight sees Rex as a weapon with which to fight other E.V.Os, and nothing more.
** This also occurs in the way E.V.Os are dealt with. If it was once human, Rex will go out of his way to cure it. If it ''wasn't'', he'll go out of his way to kill it. Partly justified by animal E.V.Os apparently lacking the mental capacity to be cured, which normally requires the consent of the E.V.O.
** White Knight, in fact, sees everyone as either a tool or an enemy, since every single human except himself is either an E.V.O or a potential E.V.O.
* WhatYouAreInTheDark
** Rex, [[spoiler: when he ran away from Providence]], spent his time stopping random E.V.O attacks. And he [[spoiler: saved White from being infected by Nanites when his suit started breaking down.]]
** White Knight, [[spoiler: when he saved Rex from falling to death.]]
* WhereTheHellIsSpringfield: Abysus is supposedly somewhere in Eastern Europe, but your guess is as good as anyone's as to where exactly it is.
* WhipItGood: Valentina in "Outpost".
* WholeEpisodeFlashback: "Promises, Promises", though it is interspersed with some present scenes of Rex's "birthday" party.
* WhoIsDriving: Bobo lets go of the wheel of the truck in episode 20 to ogle girls with Rex and Noah, cut the truck drifting off the road and into a large tree.
* WilhelmScream: Something of a RunningGag for unfortunate Providence soldiers, further establishing that they're a RedShirtArmy.
** Both the original actual Scream, and several times what sounds like someone trying to imitate it.
* WorldHealingWave: [[spoiler:In the finale, Rex uses the combined Meta-Nanite to initiate one, curing every EVO on the planet. Bobo is exempt thanks to being shielded by his proximity to the reactor, the Consortium may have managed to retain some of their power, and Van Kleiss and the Pack (not including Circe) are rescued by Breach (whose pocket dimension probably protected them). White Knight also points out that nanites are still floating around, though whether or not they can cause mutations isn't made clear.]]
* WorldOfBadass: Everyone in this show is {{Badass}} at some point, even Doc Holiday when she's feeling [[MamaBear particularly protective]].
* WorldOfCardboardSpeech: Six, short and to the point in "End Game", upon discovering that the Black Pawns are Robots:
** "I hold back against people. You're not people."
*** This also sheds light on why he is only ranked the Sixth dangerous man alive, yet he can beat his fellow higher ranked assassins.
* WouldHitAGirl: In Six minus Six, Six [[spoiler: kicks Five in the face after slicing her guitar in half.]]
* XMeetsY: ''WesternAnimation/Ben10AlienForce'' meets ''VideoGame/{{Prototype}}''.
* {{Yandere}}: While Breach has shades of this, a definite example is her "doll", [[spoiler: that little girl in Greenville.]]
* YouCalledMeXItMustBeSerious: If Six ever calls Dr. Holiday 'Rebecca' instead of 'Holiday', then you know that something really serious is going down.
* YouHaveOutlivedYourUsefulness: Van Kleiss has an entire garden of dead E.V.Os that either refused to serve him, or weren't particularly useful. They were probably very filling though.
** Kleiss hires a new E.V.O in episode 9 to replace Breach. The fool accidentally messes up Kleiss' nanite dirt suit. He's a statue by the next scene, with barely enough time for an OhCrap facial expression before the scene shift.
** White Knight implies this will happen to Rex if Six can't keep him in line.
*** At one point Rex implies that if White Knight goes too far, ''he'' might outlive ''his'' usefulness, and that a sealed room wouldn't be enough to protect him.
** Not to mention Breach's habit of throwing away her broken "toys"...
** Quarry says this almost word for word when an E.V.O henchman of his gets cured by Rex.
* YouMakeMeSic: In "Enemies Mine", Gatlocke complains about Valve misusing the phrase "begging the question", although he immediately claims to be joking and says only a total pedant would get upset about something like that. Being Gatlocke, it's hard to know if he was being serious or not.
* YourOtherLeft: In "Exposed", Holiday is watching an EVO on the monitors and guiding Rex and Bobo as to where it has gone. At one point, she tells them it went "Right" and they take off in the wrong direction. She immediately adds "Camera right!". With embarrassed looks, Rex and Bobo turn around.
* ZergRush: The bugs in "The Swarm".
